## Description

desertcart.com - ALORAIR Commercial Dehumidifier 113 Pint, with drain Hose for Crawl Spaces, Basements, Industry Water Damage Unit, Compact, Portable, Auto Defrost, Memory Starting, 5 Years Warranty, Sentinel HD55

Review: CRAWL SPACE encapsulation-ish: So far so good - I have a shallow/short crawl space (think 22'-24' inches max height) under a 1950's single story ranch home in Texas. I was on the fence about which route to go to address moisture but ended up at partial encapsulation and adding (this) dehumidifier. I say partial because I haven't insulated the walls yet and holy moly this has been a labor intensive journey that I was not willing to pay $15-$20K for. The labor is where the cost is at and this has tested my resolve. I went with this one(HD55) because there was no condensate pump which seem to fail well before the units do based on hours of reading reviews. In March I paid right at $500 after taxes (I've seen the price jump a bit now). I've added a VCMA-15 Little Giant stand alone pump that feeds into my HVAC condensate drain line, about a 9 foot run which has given me no issues and which adds more reliability. I've added a water alarm in the pan I keep the pump in and the dehumidifier sits about 8 inches above to gravity feed into the pump. I ran a dedicated 20A duplex outlet into my space to feed the unit and pump. I have two Govee smart plugs that connect to wifi and tell me the energy use of each and that I can remotely control in the event of failure. I have a tight opening that I didn't care to enlarge at 12 ¼ x 16 inches, this unit fit perfectly through it. It's absolutely miserable to crawl into and work down there but man, the savings and feeling of doing it yourself (clearly I don't value my time). But again, I'm not paying 5 figures on something I can do, I'll spend it elsewhere. My original crawl was a dirt floor and 5 foundation/perimeter vents with a decimated 6 mil barrier covering about 25% of the floor. That had the humidity at 99% in the crawl space in the summer and not too much better in the winter. I was getting ridiculously high humidity inside the house and the wood moisture readings from the joists were unacceptable. Building science has changed significantly since my home was built, yours too. It was due time to address the moisture. This unit became a necessity. I added a perimeter drain in my backyard (you need to address where the water is coming from first). I sealed the vents, I laid down a 10 mil vapor barrier and wrapped all of the 25 pillars (miserable work). After sealing up about 95% and leaving room along the walls for insulation I added this (the HD55). After letting it run for 3 days the humidity is now at 56% (i have the unit set at 50%) and it has run the entire time (which I completely understand and don't fault it for doing so). I have the humidity monitored by wifi Govee sensors that I placed down there 6 months ago, they're more accurate than the unit's internal humidistat but within an acceptable margin. This unit has been a workhorse so far. I am hesitant to give it five stars off the bat and leave y'all feeling like this is the best because of the other reviews regarding longevity but it has been a five-star experience in the time I've owned it. I've relied on the reviews others have left here so it's only fair to do my part. I will update this accordingly. I have'nt finalized the placement yet. I have it in a central location without the ducting (be aware the manufacturer specifies only 6 foot of ducting may be added), so I've held off thus far and it seems convectively fine where it is at it's current angle. Given the headroom I have I was initially going to mount it with 3/8 threaded rod with horizontal brackets that accept all thread but for now I have it 8-9 inches up on a leveled stack of insulation board I cut to fit the width/length of the unit, there are zero stability concerns and it sits plum level. If you are here I'd imagine you are facing high humidity somewhere in your home and you are going to do the DIY route - I admire that and have chosen the same. That said - would an April air unit have performed better, probably but not by much. But they have their limitations too and suffer all of the same reliability issues, probably at less frequency but I couldn't justify the $1,700 upfront cost. I may reevaluate my stance on that after the peak of this summer or the next. But for now, this unit has proven to be more than capable of a tight/shallow 1,600 foot crawl space at removing gallons of water in the air. Quite amazing when I think about it more. Would I like more features and an included remote, of course. But the $100 they charge for the remote is absolute bull 5hi7. A smart plug and wifi hygrometer is the same and less expensive. But at this price point, I am pleasantly happy, so far. The unit seems well put together and fits into my opening. It is a slight hum that you'll barely hear above and soon not notice at all. Best of luck on your moisture removal journey. Ultimately, if I pay hundreds for anything, I expect it to last - you and this company will hear about it if it doesn't. But so far I am content and imagine you will be too. I just checked on the unit and didn't bring my phone down to take pics but I'll upload some later of the actual unit. I did add the "results" from the hygrometer and a pic to show you the constraints. Regarding efficiency I've uploaded a pic from the smart plug showing the electrical use - it'll end up being about $20 a month if it works as much as it does daily (it won't have to maintain that usage 24/7) but I am showing you the peak. (Edit from 18 months later - ZERO problems and it's still humming along. I'm happy.
Review: Just installed - looks well made and was very well packed - fired right up. - I've got a sealed crawlspace under my home that needs dehumidification. I bought this unit because it is short (not a lot of height in the crawlspace) and had a ducted option, which helps me circulate dry air around several large obstructions in the space. The unit was double boxed (dehumidifier w/ 4 foam corner brackets in a box, then that box was padded and inside another box). There was a hole punched in the outer box during shipping, but the inner box was still intact and undamaged. The unit itself was in perfect condition and started right up. The funnel piece where you attach the ducting (not required) was interesting. I expected that the ducting would go OVER the plastic funnel and would be secured using a band clamp. Instead, you have to use expandable ducting with a wire spiral in it and the ducting then screws INSIDE of the funnel piece. It attached nicely (luckily I had the right kind of ducting) and it worked well. Here's the duct kit that I bought, which I would order again: https://www.desertcart.com/gp/product/B07WNK7N7F/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 The unit felt very industrial and was well made. I opened it up and took a quick look around... components were well made and electrical connections were solid. The filter is easy to remove and reinstall after cleaning. The controls were intuitive. I also bought the additional remote control (on a 25" wire, provided with the unit) and was happy with that (allows me to check on the humidity level and change settings without crawling on my belly to get under the house). It makes a bit of noise (It's got a fan moving a lot of air, so that's to be expected), but it was quieter than I had anticipated and I was happy with the sound (I can't hear it in the house, even when standing 2-3 feet above the unit (it being in the crawlspace right under the floor I was standing on).

## Features

- 113 Pint Dehumidifier: AlorAir Sentinel HD55 commercial dehumidifier can remove 113 PPD at saturation, 53 pints per day at AHAM, up to 1,200 sq.ft, lowering the humidity to comfortable levels in a short period. On the other hand, this cETL-listed dehumidifier is made of a metal outer casing that withstands more rugged conditions, ensuring long-term use and easy maintenance.

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
- Automatic Defrost: Our advanced auto-defrosting system continuously monitors the ambient temperature using built-in sensors. When the temperature is detected to be low, the unit initiates an automatic defrost cycle to prevent frost buildup and related issues. During this process, the compressor temporarily stops while the fan continues to operate, allowing the frost to thaw. Once the defrost cycle is complete, the dehumidifier resumes normal operation. This feature conserves energy and helps extend the lifespan of the unit

## Questions & Answers

**Q: How many watts does it draw?**
A: The manufacturer says it takes 4 A of current to run this device---okay, so draw this current over 120 V of potential difference (the RMS average for N. American line power), and it checks out at 4*120 = 480 W of power drawn. To run the device continuously for 24h per day, you'd use 480*24 = 11.52 kWh of energy each day (note that the other provided answer of "10kW per day" makes no sense, not because 10 is different from 11.52 (that would be forgivable) but because kWh are a measure of energy and kW are a measure of power---completely different units). Anyway, 11.52 kWh per day works out to an energy use of approximately 30*11.52 = 346 kWh each month---so at my local residential service rate of $0.1765 per kWh , I'd be paying the power company around 0.1765*346 = $61 per month to run this device continuously. That's $731 per year...

I don't know how the company can claim on its photos that this device is "energy efficient"---it lacks EnergyStar certification, or any similar such certification from any bona fide agency, and it costs more than $700 per year to run this thing in North America...

**Q: How much heat does the unit put out?**
A: The "manufacturer" answer makes absolutely no sense. Degrees is not heat, and the number of degrees it might raise the temperature of a room depends on the size of the room, the humidity in the room, the time the devices runs, the airflow in the room... etc.  In short, someone else estimated the power consumption of the unit at 480 watts. I can't swear to that, I did not do the math, but if that is correct you can use that number to determine the energy added to the system in a given period of time. If you want to just get a rough idea, then imagine the heat put out by four 100watt conventional light bulbs (some of that power is actually going to remove the water from the air)... or picture a hair-dryer set on very low (1/3 power).  A fair bit of heat.

**Q: Can it run CO all the time ?**
A: If you mean continuously-  you can leave it plugged in and set at a humidity level of your desire and the unit will turn on and run as it needs to in order to keep the moisture at the level it is set at. So in times of high humidity it will run longer versus dry times of the year.

**Q: Does it automatically stop when water is full so i can take it out and drain it outside?**
A: There is a hose  attached and it drains continuously. All you need to do is to place the house in the drain.

### ⭐⭐⭐⭐⭐ Great crawlspace dehumidifier and great company
*by J***T on December 5, 2025*

This has been a great crawlspace dehumidifier. It's been running great for 2 years. It's small enough to fit through crawlspace openings and built like a tank. The main board developed an issue after 2 years and a quick email to support and I received a new board. The unit is back to working perfectly. Alorair really stands behind their products.
