Specifications:
  • Area Coverage: 1,800 sq. ft.
  • Max Water Removal (Saturation) PPD: 95 pints/day
  • Max Water Removal (AHAM Standard): N/A
  • Process Air: 259 CFM
  • Power: 7.3 amps
  • Filter Type: Washable Filter
  • Drain Hose Length: Not included
  • Power Cord Length: 6 feet
  • Housing: Durable plastic
  • Operating Temperature: Down to 41°F
  • Auto-Restart:
  • Auto-Defrost:
  • Auto-Diagnosis:
  • Timer:
  • Wheels:
  • Warranty: 1-year full/5-year sealed system




This is an ideal pick for a coffee shop or a workshop, as it has a coverage capacity of 1,800 sq. ft. and can collect around 95 PPD of water. The fan runs at two different speeds and boasts a peak of 259 CFM. Nonetheless, the air isn’t simply drawn inside with all the impurities but it is purified first to prevent dust and other contaminants from damaging the mechanism. Another great news is that you can simply clean the mesh when it gets too dirty and place it back for a new round of filtering. No extra expenses on replacement filters.

Concerning the design, it is strong enough to resist tough circumstances. The plastic casing is durable and provides good sealing for the inner mechanisms. It integrates side handles and comes with 4 robust rollers for trouble-free transportation around the place, which could include carrying it on the stairs. It comprises a 6’ cord to place it far from the wall and decrease vibrations. The only detail it lacks is a pump that would have made water discharge easier. It does present a permanent drain possibility, but it is contingent on gravity to evacuate the water. Consequently, the unit should always be situated at a higher ground so the water can flow into the drain.

If you don’t opt for constant drainage, it offers a generous front container with a splash guard that can be effortlessly detached. But note that it has a smaller volume than this model’s dehumidification rate, therefore may have to empty it more often.

The price is indeed very attractive, particularly when we consider the 1-year service contract for the entire unit or the 5-year contract for the closed system. They are supplied by a renowned brand name, so you can be certain that they will be honored. But, conversely, we should refer to the expenses, which are not as reduced as you would have anticipated. It is Energy Star verified, but it consumes up to 870 watts, which will certainly show on your power bill if you resolve to run it continually. Some purchasers, however, noticed that if you run it on the lowest setting and pause it once every 24 hours, you can decrease the costs to a decent value.

Often ignored, the space under the house can easily turn into a hazardous place, where vermin and mold can multiply and, in time, find ways to move in the house. To protect your family, see our top-rated dehumidifiers for crawlspace and ensure humidity is kept under control.
What we like:
  • Quick wetness removal
  • Easy set up in less than 15 minutes
  • Uninterrupted drain option
  • Self-thaw prevents its internal components from freezing
  • Easy to transport
  • The timer allows for run-time customization and helps save power
What we dislike:

✖ It is contingent on gravity to dispose of the water
✖ The humidistat is not very accurate
✖ High power intake rate

Verdict

For a small space, this unit can work wonders. It is up for prolonged use and can face pretty tough situations. It is made by a trustworthy brand, so you can expect full coverage when it comes to repairs. A responsive customer support service is also at your disposal.


Q: Can the casters be detached?
A: Yes, you can detach them and make the unit shorter to fit lower spaces.



10. Waykar 130 Pints

Check Price at Amazon


Specifications:
  • Area Coverage: 6,000 sq. ft.
  • Max Water Removal (Saturation) PPD: 130 pints/day
  • Max Water Removal (AHAM Standard): N/A
  • Process Air: 180 CFM
  • Power: 9.8 amps
  • Filter Type: Washable Filter
  • Drain Hose Length: Not included
  • Power Cord Length: 6.52 feet
  • Housing: Durable plastic
  • Operating Temperature: 41-95°F
  • Auto-Restart:
  • Auto-Defrost:
  • Timer:
  • Wheels:
  • Warranty: 1-year full/30-day refund




It’s advertised as a model that can cover 6,000 sq. ft. but from our expertise, it should be used in spaces smaller than that. Still, it manages to retain around 130 pints of water daily. You will also like its design, which doesn’t resemble the other models, this one boasting a more modern and elegant housing, with rounded corners and a large grille at the front, that hides the reusable filter. Plus, it has wheels for easy transportation and two recessed handles so you can place it anywhere needed. It can handle extremely moist spaces reaching 80%, so don’t be afraid to use it for water damage repairs or for drying a construction.

The integrated humidistat enables it to sense environmental humidity so you can have real control over it and make the correct settings that will eventually reduce the level. Once it reaches the targeted moisture, it will turn off only so it can turn on back again when it starts to increase once again. Hence, you can leave it unattended and it will surely get its job done.

It works in any condition, no matter the season, as it self-defrosts in the winter when the coils accumulate ice and can handle excessive heat up to 95 degrees in summer.

  • Power Outage Restart: it also turns on again once it regains power, in case of a shortage
  • Automatic Drain: The 6.5 feet long hose can eliminate the retained water by simply placing it in sewage at a lower height
  • Manual Drain: It has a 5l reservoir to collect the water in case the auto drain is not available. Don’t worry about overfilling as you will be announced by a light indicator whenever you must empty the reservoir. When that light appears, the motor automatically stops
  • Customer Support: Don’t hesitate to resort to the help of the service team, as you will benefit from lifetime tech support and a 30-day money-back warranty, along with 1 year of free repairs, with the option of extending it to 2 years
Sometimes, the increased indoor temperature is strongly related to a high moisture level. See our smallest window air conditioners and get improved comfort, less moisture, and lower energy costs, all at a fairly good price.
What we like:
  • It looks modern, more appealing than the rest of the models
  • The washable filter is a nice touch
  • The water reservoir is hefty
  • The timer lets you set it and let it unsupervised
What we dislike:

✖Seems very loud even on the lowest level
✖The drain hose doesn’t attach too securely

Verdict

We liked all the smart settings it provides, especially considering the cost that is more than half of what other models cost. It incorporates most of the useful and indispensable features and it turns out to be very comprehensive. However, it’s best to have it work in a space smaller than advertised because it might not rise to the expectations.


Q: Can the casters be detached?
A: Yes, you can detach them and make the unit shorter to fit lower spaces.

Once you buy it, repairs and parts will be covered for 1 year.

Moisture doesn’t always appear as a consequence of a flood. It can be caused by the condensation that takes place in the bathroom and a whole range of other motives. If you often see droplets on your bathroom tiles or even on the walls, it’s time to invest in one of our best-rated dehumidifiers and keep mold under control.
What we like:
  • It can be easily moved despite the heavy weight
  • It defrosts automatically
  • The filter increases the efficiency in improving air quality
  • It works with various external humidistats
What we dislike:

✖The large top handle makes it hard to fit in crawlspaces
✖It sometimes shows incorrect readings

Verdict

Truly useful machinery that can handle large amounts of water, it is of great efficiency in removing moisture from walls, pieces of furniture, or simply the air. It’s straightforward and reportedly accurate, although it can sometimes show wrong levels until you restart it.


Q: Does it have a humidistat?
A: Yes, it has an integrated one, but it also works with other humidistats.



8. AlorAir Commercial Dehumidifier

Check Price at Amazon


Specifications:
  • Area Coverage: 2,300 sq. ft.
  • Max Water Removal (Saturation) PPD: 190 pints/day
  • Max Water Removal (AHAM Standard): 85 pints/day
  • Process Air: 210 CFM
  • Power: 5.4 amps
  • Filter Type: Washable MERV 8
  • Drain Hose Length: 15 feet
  • Power Cord Length: 19.5 feet
  • Housing: Rotomolded polyethylene
  • Operating Temperature: 33°F – 105°F
  • Auto-Restart:
  • Auto-Defrost:
  • Auto-Diagnosis:
  • Timer:
  • Wheels:
  • Warranty: 5-year




Removing moisture after a flood can be a problematic task, expressly if the space you are attempting to dry is ample. You will need a forceful unit that can work continuously for days in high-humidity conditions without being influenced by cold or rust. Tests revealed this model from AlorAir to be the best in these circumstances, as it has a very sturdy construction and comes with a pump to help drain the gathered water. The coils are epoxy-covered, therefore they will preserve their heat transference ability for longer.

The housing is made of rotomolded polyethylene, which is practically indestructible, very resistant to bumps and water. The system is completely sealed with rubber bands and can be immersed in the water without getting wrecked or developing rust and corrosion. Therefore, you don’t have to wait until the water is eliminated completely to start the restoration process. The fan is actioned by a 5.4 amperes motor that generates a high airflow of 210 CFM. Consequently, it can handle up to 2,300 sq. ft. The water withdrawal rate is impressive, with up to 190 pints of water that can be removed daily, or up to 85 pints conferring to AHAM standards.

It includes a 15 feet hose and 19.6 drain pipe and comprises a solid pump that will raise the water to a height of 14.7 feet. The cord is long as well, measuring 19.6 feet, so you can place it far from the wall for increased efficiency. Regarding its size, we have observed that it is more compact than most versions in its class and more lightweight, so it is easier to lift, chiefly as it comes with 2 rugged handles. Nevertheless, the burden is still serious, and it could use a set of wheels for easier transportation.

The electronic panel is straightforward, with only 4 buttons that allow for easy setup and function selection. It self-restarts and can function in subzero settings. The system can work at temperatures between 33F and 105F. Plus, the service assurance is very generous, as the company offers 5 full years for repairs.

What we like:
  • Watertight construction
  • Powerful airflow can cover large spaces
  • Very high water withdrawal rate
  • High-quality water pump
What we dislike:

✖Lacks wheels

Verdict

It draws less energy than the competition and comes with a timer, so the expenses of running it will be lower. Additionally, the hardwearing construction warrants that it can run in different conditions and keep doing a good job even after years of utilization.


Q: Can you install wheels on this unit?
A: Unfortunately, a wheel kit is not available, but you can stack the units and move them with a standard hand truck.



7. BlueDri BD-76P-RED

Specifications:
  • Area Coverage: 600-900 sq. ft.
  • Max Water Removal (Saturation) PPD: 150 pints/day
  • Max Water Removal (AHAM Standard): 76 pints/day
  • Process Air: 235 CFM
  • Power: 7.3 amps
  • Filter Type: Washable air filter

It is a versatile model that can be used in any location, whether we are talking about a construction site where the excessive dampness must be drawn fast, or in a cellar that was flooded and needs to dry out for the restoration to begin. The case is built of molded polyethylene, therefore it offers excellent protection against scratches and bumps, allowing for use in extreme circumstances. It rolls on two semi-inflatable wheels and integrates a rigid handle, so you can move it around if the whole space has been flooded.

It has a notable water withdrawal ability of 150 PPD in a space of up to 900 sq. ft. It isn’t the best area coverage, but many models promise to cover thousands of sq. ft. and prove to be ineffective. Tests revealed that, although this unit can perform well in bigger parts of the building, if used in a space under 900 sq. ft., it is exceedingly fast and performs as described. Additionally, it comes with a pump, which is already an extra, but very useful if you don’t have a ground drain.

It can work for days in cold environments, with values that can fluctuate from 33F to 100F. It has self-thaw and will resume on its own in case of a blackout. The electronic panel is located on the top, allowing for quick access to settings. It comprises an LCD as well that will show humidity points and count the hours of continuous use.

The stackable design will help you save space in your storage if you decide to buy more than one unit.

What we like:
  • Heavy-duty housing
  • Large rollers and rigid handle make it easy to reposition
  • The pump helps raise water to a higher level
  • Restarts on its own after a blackout
  • Stackable design
What we dislike:

✖Some purchasers found the directions to be hard to understand

Verdict

It is offered at an excellent price and can be put to work in a broad variety of spaces, so you will make a good investment no matter if you are planning to use it on a construction site or to restore your whole house after an unfortunate flood. Plus, it is toughly built and covered by a long warranty.


Q: What material was used for the casing?
A: It is built of molded polyethylene.



6. COLZER CFT4.0D

Check Price at Amazon


Specifications:
  • Area Coverage: 8,000 sq. ft.
  • Max Water Removal (Saturation) PPD: 232 pints/day
  • Max Water Removal (AHAM Standard): 110 pints/day
  • Process Air: 353 CFM
  • Power: 15 amps
  • Filter Type: Washable high-dense filter
  • Drain Hose Length: 6.56 feet
  • Power Cord Length: 5.9 feet
  • Housing: Scratch- and dent-resistant metal
  • Operating Temperature: 41℉ -95℉
  • Auto-Restart:
  • Auto-Defrost:
  • Auto-Diagnosis:
  • Timer:
  • Wheels:
  • Warranty: 2-year


This model offers a complex electronic panel with multiple smart functions that make it easier to customize for specific operating conditions. It comprises a digital humidistat, which is very accurate in tracking humidity values in the room. The two arrow buttons that are situated next to the large LCD screen allow you to set the preferred level and the system will run continuously until it is reached. It also incorporates a temperature sensor, which can be used in conjunction with the self-thaw function to reduce freezing effects. Additionally, a timer is available, which can help you save a lot to save energy, considering that this unit does eat a lot of power, with a peak usage rate of 1,400 watts.

Nevertheless, if we consider its ability to cover up to 8,000 sq. ft., the power usage rate can seem decent, as, usually, for this surface are used two units instead of one. The water withdrawal rate is outstanding, reaching up to 232 PPD or 110 pints according to AHAM norms, so we have ranked it among the fastest models. The fan can supply up to 353 CFM, and the air will be drawn through a high-density filter, designed to capture dust and other particles that can end up inside the system and gradually reduce its performance.

The case is built of strong metal that stands bends and scratches. It is provided with 2 semi-inflatable wheels that ease transportation from one work site to another and a large rugged handle for easy manipulation that attenuates a bit the discomfort of its bulky construction. These features, along with the self-restart allow you to set it functioning in any place and forget about it, as it is not prone to rust and can restart its system if a blackout arises.

The only defect we could find was the lack of a pump. It does offer permanent drainage but it’s based on gravity, so it requires a floor drain. The 6.56 feet hose and 5.9 feet power cord are pretty short as well when compared with the other models. However, it does make up through easy maintenance, as it features an error-detection function that signals malfunctions and allows you to obtain troubleshooting tips through error codes. Plus, the whole system is covered by a pretty good 2-year service assurance, which is offered by a reliable brand.

What we like:
  • Multiple smart functions
  • Portable design
  • Suitable for large job places
  • Fast water withdrawal in large areas
  • User-friendly electronic panel
  • Accurate digital humidistat
What we dislike:

✖No pump
✖Can reach high energy consumption rates

Verdict

It can do the job of 2 average units with maximum efficiency. The metal housing makes it practically indestructible, while the electronic panel makes it expedient to use. Plus, it comes with many smart functions, so it can run independently for long periods.


Q: Can a garden hose be attached to the drain?
A: No. A hose of this type would be too large. It requires a 3/4 tube.



5. XPOWER XD-125

Check Price at Amazon


Specifications:
  • Area Coverage: 1,500 sq. ft.
  • Max Water Removal (Saturation) PPD: 125 pints/day
  • Max Water Removal (AHAM Standard): 76 pints/day

  • Auto-Diagnosis:
  • Timer:
  • Wheels:
  • Warranty: 1-year

In areas that have been flooded, the dampness level is so high that only a commercial model with a strong pump can resolve it. You need a powerful motor and a pump that can quickly get the collected water out of the room, and XPOWER offers them, along with a long 20’ drain hose and a purge function.

The advanced electronic panel allows you to set the humidity standard between 26% and 90%, and the unit will work to bring it to the selected value. You can follow its progress on the LCD, which, apart from the RH value, will display total working hours as well. It cannot resume its run, but the self-thaw mode is present and will periodically heat the coils to maintain them in good shape if the temperature drops down to 41F or even lower.

With a water withdrawal capacity of 125 PPD and an airflow of 235 CFM, it will do its best in a medium-size space of up to 1,500 s. ft. Thus, it is the correct option for underground rooms, attics, shops, or construction sites, at which it was already tested and did exceptionally well. The housing is made of rotomolded polyethylene, which is the standard in the industry for its strength against parameter variations and its resistance to bumps and scratches. Two strong semi-inflatable wheels were added to absorb the shocks and slickly roll the unit on any terrain. A rugged handle will help you move it without bending and will prove very efficient if you need to carry it on the stairs.

It comprises a washable high airflow filter that will strain contaminants and remove microorganisms and mold spores. The 25’ cord allows you to find a good spot for it in the room. Moreover, the whole system is backed by a good 1-year service contract that can be used in case of manufacturing flows or other mishaps that are specified in the agreement.

What we like:
  • A strong pump can send the water to a considerable height
  • Can operate in cold environments
  • Easy to set up as it requires minimal assembly
  • Self-thaw function
  • Resistant housing and coils
What we dislike:

✖No self-restart function
✖No timer

Verdict

As it comprises a pump, it can handle all the hard work without supervision. You will only have to program it and check once in a while if everything is working as it should. The control panel will let you check the parameters and adjust the settings with ease.


Q: What does the manual water purge override function do?
A: It allows you to manually discharge the water collected by the machine when you need to clean, repair, or transport it.



4. Dri-EAZ F413 Revolution

Specifications:
  • Area Coverage: 7,000 sq. ft.
  • Max Water Removal (Saturation) PPD: 136 pints/day
  • Max Water Removal (AHAM Standard): 80 pints/day
  • Process Air: 180 CFM
  • Power: 6.2 amps
  • Filter Type: 3M HAF

  • Auto-Defrost:
  • Auto-Diagnosis: N/A
  • Timer:
  • Wheels:
  • Warranty: Limited lifetime on body, 6-year on compressor & coils, 1-year parts & labor

This brand is renowned for its high-quality dehumidification solutions which include both commercial units and products for residential use. Although their prices are higher than the average, we must admit that they deliver superior quality and excellent performance rates, so investing in a model like F413 Revolution will only bring you benefits in the long run. Everything is well-thought and carefully engineered for long-time use, starting with the rotomolded poly housing that encases the rust-resistant coils and ending with the superior functions that make customization easier.

The electronic panel has well-labeled buttons and an LCD that helps you set the preferred humidity. The value can range between 40% and 90%, and we advise you to run it at 50% for mold limitation and set it to 40% if you have recently dealt with a flood. With the digital humidistat, it presents three smart functions, namely a timer – for a customized run, self-restart – with a recall function that enables it to resume its activity in case of a blackout, and self-thaw – for cold periods.

It can provide fast water withdrawal for extra-large spaces of up to 7,000 sq. ft. or a volume of 15,000 cubic feet, so it is a viable choice for warehouses, professional garages, offices, or whole houses. It can draw up to 136 PPD, as it uses a strong fan to generate an airflow of 180 CFM. The air is drawn through a 3M HAF filter that includes an anti-microbial agent. Nevertheless, this is not a permanent filter, so you will have to replace it every 4 to 5 months to maintain the system’s performance.

Another expedient aspect is the built-in pump, which replaces gravity and even works against it by sending the water up through a long 25’ drain hose to the draining your preference. Moreover, the cord measures 40’, so you can place it near the window or sink even if the outlet is situated across the room. Worthy of mentioning as well, it can be linked to a duct if you choose to acquire the optional kit.

What we like:
  • Very effective in large spaces
  • Integrates a pump
  • 3M HAF filter is very effective in eliminating microorganisms and mold spores
  • Can be connected to an HVAC system
  • Strong construction
  • Long service contract
What we dislike:

✖Some users complained the hose leaks
✖It tends to slip in the stackable assembly

Verdict

If you are looking for quality, you should take a good look at this unit, which was certainly made to last. Everything, starting from the housing to the pump mechanism, was meticulously crafted to deliver remarkable results. Furthermore, multiple functions were encompassed for easy customization.


Q: Do you need to close the windows and doors before using it?
A: Yes. This is actually how all moisture withdrawal machines work. If you allow the outdoor air to enter the premises, it will affect the performance of the unit.



3. Aprilaire 1852 Pro

Check Price at Amazon


Specifications:
  • Area Coverage: 5,200 sq. ft.
  • Max Water Removal (Saturation) PPD: 95 pints/day
  • Max Water Removal (AHAM Standard): N/A
  • Process Air: 265 CFM
  • Power: 8 amps
  • Filter Type: Washable MERV 8
  • Drain Hose Length: 5 feet
  • Power Cord Length: 8 feet
  • Housing: Scratch- and dent-resistant metal
  • Operating Temperature: Down to 40°F
  • Auto-Restart:
  • Auto-Defrost:
  • Auto-Diagnosis:
  • Timer:
  • Wheels:
  • Warranty: 5-year

It presents a hard-wearing metal case that can resist scratches and dents and comprises corrosion-resistant aluminum coils. The feasible design allows you to integrate it into the HVAC system and provide water removal for your entire business place, particularly as it can cover up to 5,200 sq. ft. Nonetheless, you can decide not to duct it, if you need to cover an individual space, as it offers permanent drainage and comes with a 5’ hose. Thus, no matter the option you pick, you will avoid water reservoirs or buckets that usually fill too fast and need to be drained multiple times a day.

It packs an 8 amperes motor and supplies a notable 265 CFM airflow. Regarding the dehumidification rate, 95 PPD is a good value, but we must agree that it is not very fast. Though, you can enhance its functioning if you use it in an area of reduced dimensions or, if you buy 2 units, for your extra-large business place.

It comprises a washable MERV 8 filter, which is very sturdy and useful against impurities and large floating particles. Proper care and cleaning will extend its life, so you will only have to put a new one once a year to preserve the system in good shape. It has rollers for easy transfer, but it doesn’t have a handle, so carrying it on the stairs may be problematic. Nonetheless, it requires minimal upkeep and can stand cold air down to 40F. Additionally, it is backed by a very generous service contract that can be used in case of manufacturing flaws or mishaps.

The self-restart will show its value as well, as it won’t allow for long periods of pause within the water withdrawal process. Plus, it eats less power than the competition, with a peak of 638 watts, so running it for longer periods will be less expensive. Nonetheless, you won’t be able to program its functioning time as no timer is available.

What we like:
  • Very long 5-year service contract
  • Self-restart after an electrical malfunction
  • Works in cold environments
  • Can be integrated into an HVAC system
  • Long-lasting filter
What we dislike:

✖It is relatively slow
✖Doesn’t feature a timer

Verdict

Most purchasers pick it for its good price and performance, but there’s no doubt that the simple upkeep plays an important role as well. The fact that it can function as a part of the HAVC system is also a bonus, while the good service assurance makes it even more attractive.


Q: Where is this unit manufactured?
A: Aprilaire products are manufactured in South Central Wisconsin.

Large areas with increased humidity need to be handled by models with a high moisture intake rate like this one. Able to cover up to 8,000 sq. ft., it’s among the most powerful that can absorb water not only from the air but also from walls or furniture. Its compressor ensures it can collect no less than 296 pints in 24 hours, that is 143 PPD according to the AHAM standard. Don’t be afraid to use it in construction sites, warehouses, basements, etc. The fan circulates around 353 CFM, which is an outstanding performance. It can be used in extreme conditions, with a maximum temp level of 95 degrees and humidity exceeding 80%.

In terms of construction, we are talking of a solid metallic housing that is not prone to rust or damage, measuring 19.5(W)x 15.7(D) x 32.5(H) inches, significantly more compact than its competitors. Hence, you can squeeze it in confined spaces where other bulkier models wouldn’t fit. Don’t assume you will have a hard time moving it, as it includes two recessed handles on the sides and four solid casters.

It’s very intuitive, particularly due to the large touch-pad panel that displays all the settings and features. You will there find readings of the current humidity and temperature, and pictograms of all of its settings. Drainage can be done in two ways:

  • manually, in the 3.17-gal. bucket
  • automatically, using the integrated pump and the 3.28 ft. drain hose

It is packed with some smart features that guarantee optimal working conditions:

  • Auto On/Off: to ensure it will not work in vain, the machine starts and turns off at required times, to preserve the set humidity
  • Auto Stop: in case drainage is done manually, it will turn off when the bucket is full
  • Auto Defrost: it performs upkeep as it defrosts the ice that builds up on the coils in the cold season
  • Auto Restart: in case the power goes off, it remembers the settings and retakes them when the power comes back on
  • Timer: set it to work for a certain period from 1 to 24 hours
  • Error codes: it shows codes of the problems it encounters for effortless troubleshooting

The protection policy provided lasts for two years.

What we like:
  • The fact that it remembers and retakes the settings
  • Drainage can be done in two ways
  • It has a large surface coverage
  • It can be easily relocated
  • The large display provides intelligent humidity control
What we dislike:

✖Customers were upset with the quality of the customer support

Verdict

Indeed a heavy-duty model, it can not only draw a large amount of moisture, but it can also handle very large areas without it affecting its performance. Starting with the straightforward design and the series of smart settings, it proves to be a helping hand in drying tasks or restorations after a flood.


Q: Can you set a specific humidity to reach?
A: Yes, you can use the touch panel to make this setting.

When it comes to producing commercial models, Dri-Eaz surely knows the business. This is one of their most dominant products, designed to ensure optimal water withdrawal for restaurants, hotels, construction sites, or warehouses. In this direction, it was equipped with strong housing and advanced dehumidification technology that allow it to run in low-grain environments. It uses smart sensors to measure temperature and humidity and can adjust its operations to reach optimal parameters fast and efficiently.

Fast Moisture Removal

Many customers choose it for water damage refurbishments, as it can provide quick water withdrawal and work continuously without overheating or losing power. Plus, it comes with a high-quality pump, which provides efficient drainage by lifting the water and allowing evacuation into a sink or out the window. Its popularity is amplified by the following specifications:

  • Extra-large coverage – can provide moisture withdrawal for up to 26,000 cubic feet, being a perfect choice for whole buildings
  • Outstanding water withdrawal capacity – draws up to 235 PPD
  • Crossflow technology – ensures optimal dehumidification even if you have to deal with a low-grain environment
  • Powerful fan – produces an excellent 325 CFM airflow, which reduces water withdrawal time

It can run at temperatures between 33F and 100F so it won’t freeze in extremely cold conditions. Furthermore, the pump bassinet is very generous, so it can control the surplus of water produced by defrosting in case a blackout occurs. Thus, you can be sure that all its work won’t be wasted and the humidity won’t be raised again by accidental spills.

Indestructible Construction

It is an industrial unit, so it should be able to run for extended periods in harsh circumstances. Moreover, as you will invest good money into it, it should last for many years, and preserve its performance. Our investigation revealed that it is fit for the job, and this is easy to see if you look at the following features:

  • Rotomolded poly housing – is resistant to dings and dents and won’t get damaged if exposed to high humidity
  • Heavy-duty hose and cord – the first one measures 25’ and the second 40’, being appropriate for use in large spaces
  • Performant 3M HAF filter – is anti-microbial treated and will fight mold and mildew spores and microorganisms
  • Strong semi-inflatable wheels and handle – make it easy to transfer from one job site to another, even if stairs need to be climbed

Though it is bulky and rather heavy, at 121 pounds, with the ergonomic handle, it is easy to maneuver. Plus, if you purchase 2 units, they can be stacked one on top of the other to condense the space they take on the floor when stored. To provide this option, the handle easily folds down.

Smart Functions

Now, that we have analyzed its construction and capacities, it’s time to inspect its design. Is the control board easy to reach and operate? It is. It features 4 buttons and an LCD that allow you to set the desired functions, like, for instance, the moisture level it should reach. Nevertheless, what’s truly impressive is the multitude of smart functions:

  • Self-thaw – it triggers when the cold kicks in and shields the inner coils against cold and freezing
  • Self-diagnosis – generates error codes that can be used for easy troubleshooting
  • Self-restart – in case a blackout occurs, it learns the last settings and resumes on its own
  • Timer – helps customize run time and decrease energy expenses
  • Digital humidistat and thermostat – analyze the parameters on the premises and allow the unit to adjust its functions accordingly

Apart from all that, you can select the language, as it offers information in English, French, German, and Spanish. It also includes a wireless function that allows it to connect with a special monitoring system (sold separately) that will help you track the site state.

Long Service Contract

The housing is backed by a limited lifetime service contract, and you will perhaps never have to use it, as it is one of the most solid models. Conversely, if something should happen with the compressor or the coils, note that they are covered for up to 6 years, which is a very generous offer. Moreover, you get 1 year for parts and labor, and the pledge that the manufacturer will stand behind their offerings.

What we like:
  • High area coverage and water withdrawal rate
  • Easy to adapt due to the multiple smart functions
  • Sturdy construction
  • Built-in pump
  • Large pump basinet prevents accidental spills
  • Multilingual control panel
Verdict

The most trustworthy of all, with a high capacity and quick action, this machine is everything you need to ensure a safe environment in large building spaces. It is enough to program it and it can take it from there as it can evacuate the water on its own. Plus, you can always know how it is performing from a distance as it can transmit all the info through WiFi.
