Features

  • [SUPER CONVENIENT USAGE] This high-quality dehumidifier is adjusted simply to the ideal humidity setting to minimize moisture and reduce odor. The MERV-1 Filter can protect internal components from dust when dehumidifying. The most convenient point is that you are not requested to pour away the water every hour like a typical domestic dehumidifier, there is no tank inside, it drains automatically.
  • [AUTO DEFROSTING SYSTEM] Auto defrosting is important, as ice buildup on the dehumidifiers coils can cause the units to malfunction. AlorAir commercial dehumidifier can truly make the dehumidifier work at the Low temperature (36 degrees Fahrenheit). The unit works continuously and efficiently without periodic stopping during the defrosting process. Not only saving the energy but also making the unit last longer.
  • [SAME FIT FOR CRAWL SPACES & BASEMENTS] We designed this professional dehumidifier with the modern consumer in mind, smaller size, compact design, rugged handle, easy and safe to transport from job to job, and even from downstairs to upstairs.

    • Great well designed unit fixes common dehumidifier design errors; Super support staff
In spite of some problems that I initially encountered, I believe that for its operating capacity the Alorair H55 (Blue) Sentinel dehumidifier is one of the best products on the market place today. Why do I think this dehumidifier is so good? To be honest my past experience with the entire dehumidifier manufacturing industry has not been a happy one. In the past 10 years I have bought (and obtained through warranty exchanges) over 8 dehumidifiers. I have a relatively small encapsulated crawl space (1,400 SF) which I kept dehumidified using residential 35 Liter per day units. The units that I bought were manufactured by Frigidaire, Friedrich, and Hense. They are all junk! They are designed to fail within 12 to 24 months. Although one would think with the vast choice with the plethora of various manufactures of residential dehumidifiers that quality would vary; having removed the cover off of these failed units it appears that the functioning components (compressor, condensing, and evaporating coils) are all the same and probably come from the same factory located somewhere in China. Why do they fail within such a short period? Bad design. (1) The evaporator coils operate under high pressure 410 Freon, with thin walled copper tubing (environmental and energy efficiency improvements), packed with aluminum cooling fins for condensing room humidity, all held together with carbon steel plates on the ends of the coil unit. The high pressure Freon environment within the thin copper tubing fails within 24 months due to formicary corrosion caused by the dissimilar metals (aluminum, copper, and carbon steel) in contact in a damp environment setting up a corrosion voltage differential on the evaporator coil. (2) Placement of the humidity sensor directly in contact with the evaporating coil in the upper corner, insures multiple and repeated false starts for the dehumidifier compressor. When the unit shuts down after reaching proper humidity levels, the evaporator coil is still wet, and as it drys out the humidity released will send a false signal that the room humidity is too high and thus trigger the unit to start up. Worse when moisture evaporates, the resulting water vapor is lighter than air and rises and triggers the sensor. Excessive cycling on and off results. Lastly it is impossible to repair the units when they fail. They are intended to be disposal products. When I hauled them off the the landfill (as hazardous waste) it was shocking how many failed dehumidifiers were stacked together at the landfill. I finally decided to quit buying junk and started researching crawl space dehumidifiers. Most crawl space dehumidifiers are overpowering for my needs (100 ~ 200 pints per day). The Alorair HD55 is one of the smallest crawl space dehumidifiers on the market. And it is a quality design. This unit has a coated coil (in which the aluminum fins and copper tubing are coated) and is held together with stainless steel plates all of which protects against premature evaporator coil failure due to formicary corrosion. Secondly the humidifier sensor is separated from the evaporator coil and is located on the lower end of the unit to minimize triggering by evaporating moisture from the evaporator coil. Additionally a remote controlling sensor is available as an option with a 25 foot cable to enable full separation from the senor from the evaporator coil. The unit has a MERV 8 removable filter to keep the coils clean. It is very quiet when operating. The only way for me to tell if the unit in the crawl space is running, I have to put my ear against the floor to hear it as the sound is too faint. Additionally, I highly recommend the hanging unit when installing. The rope system minimizes the conduction of vibration, and it raises the unit to get more height when running the gravity drain pipe. Additionally operating the unit directly below the floor joists is more efficient as humidity rises and can be more effectively removed during operation, than if the unit is located on the crawlspace or basement floor. Another plus is that while the humidity sensor operates to the nearest 5%, the actual humidity setting can be set within 1% intervals. I have a separate hygrometer sensor in the crawlspace which measures humidity within 1% intervals. This unit is able to keep a steady humidity level of 41% with a variation of only 1 % +/- when using the remote controller and keeps a steady 40% with no variation when using the sensor on the unit. None of the other junk units that I used to own could keep a steady humidity level, as they operated with variations of +/- 5% at a 45% setting. Yes I did have some problems as the first unit delivered failed almost immediately It is not clear whether the unit was defective or whether it was damaged in shipment. I suspect that damage in shipment is a common problem. The support staff was very responsive and arranged to get a replacement unit shipped to me in two days. I was also given a return label for me to ship the defective unit back at no cost. Replacement unit is running great. I would highly recommend that you save the shipping box for any future returns. In spite of this I still recommend this unit. ... show more

    • Consider sizing up if you are dealing with abnormal environmental conditions
MY ASSESSMENT: I like this machine and was very happy with the timely delivery, ease of set up and the low amount of noise it generates. I am however planning to return it as it does not appear to have the capacity to dehumidify as the specs imply based on my specific conditions. MY SITUATION: To give a little more context to this decision, my home is in a river basin in the Southeastern United States. The area I am dehumidifying is my crawlspace. The size is 1200 sq. ft. (which is EXACTLY what this unit is spec'd for). I have a feeling this machine is spec'd for "normal" conditions as anyone who lives in the South will tell you things can get pretty abnormal in terms of humidity. WHAT I FOUND: after running it for over 72 hours it is has not been able to pull the humidity down to the level I prefer (50%). I have 3 temp and humidity sensors in my crawlspace and they have been fluctuating between 57 and 65% (Started at 75%) since starting this machine up. Even the sensor on the unit itself has only been able to pull down to a low 56%. (Just checked it and it is back up to 61%). That said, having this machine run constantly until winter (when things "dry down") does not seem practical. EDIT: We just had a cool front come through that dried things out and the RH in my crawlspace finally dropped to 50-52%. That said, I believe my assumptions on my specific conditions is true. NEXT STEPS: Planning to SIZE UP considerably. I've read reviews on some of the 180 -220 PPD units and people seem to be very satisfied with their performance. I know it may be overkill and I will be spending a bit more money, but I'd rather have a unit that works harder in shorter intervals than something that runs 24/7 and burns out in a years time. ... show more

This was a bargain compared to some other brands I checked, and the quality is top-notch. I installed this into a very damp crawlspace that was running 90% humidity during the dry/cold winter season. It's kept my approx 600 sq ft space close to 60% humidity all summer— even without a vapor barrier. I also bought their hanging kit (which I recommend for ease of use). The only thing that remains to be seen is how long this lasts,but so far (8 months) so good. This is WAY more than adequate for my application. ... show more

    • Excellent at dehumidifying, could use some improvements though
I gave this a 4 because it's primary job - dehumidifying - it's a pretty good beast at. I have used it to dry up my mechanical room, a flooded hallway with carpeting, and it removes a lot of water in not a lot of time. Controls are simple to use and the entire unit is pretty stout. Where it can be improved: 1. The metal seams on the bottom of the unit are not watertight. As water builds up inside the unit, if it doesn't hurry up and get out of the drain it leaks around the metal seams. I've set this unit level and unlevel a number of different ways and best setup I found was slightly unlevel front to back with the back end higher so water accumulates near the gravity drain faster. 2. The drain hose setup. They should give you a threaded option so you can hook this up in a hard-pipe type method. The flexible hose that you end up using on the nipple is crap and kinks constantly so you have to really have this very close to a drain where the hose can be just a foot long or so. It's also just a pressure fit on the hose, and the barbs don't grab very well so the hose can pop off pretty easily. I would buy it again but the design of it could use improvement. ... show more

    • Great Customer Service
I had an issue with my Sentinel HD55 where it would need to be restarted every few days. I reached out to customer support and was helped by Eileen. I was quickly sent replacement boards which were very easy to install. I have had no problems with the unit since then. Eileen checked back in later to make sure everything went well. ... show more
