## Description

Review: Met my expectations (and I'm picky) - We live in a house built in 1940. The walls are rock, and 13" thick, so no moisture barrier or insulation. Same goes for the slab; nothing to stop moisture coming through. The house has always smelled musty. My wife is allergic to mold, so I needed to reduce the moisture inside the house in order to make it an unfavorable environment for mold growth. When I got the unit, it was plug and play: Just route the drainage hose to the outside, plug into power, turn it on, and let it get to work. Even without ducting, the humidity level in the most distant room reduced to 55% (with the humidity level set at 45%). Over the past few weeks, I have been ducting it into my HVAC, which could never bring the humidity below 80% (we live in Florida, near Gainesville). I first plumbed the exhaust (dry air) into the return at the base of the air handler. That move brought the humidity in the most distant room to 50%. Next, I bought 75 feet of Cat 8 cable, and installed the remote control near my HVAC thermostat. That worked perfectly. Finally, I cut an opening to my HVAC return 8 feet above where I connected the output duct, and ran flexible 10" ducting (Rubber-Cal HVAC Ventilation-Flex) to the intake on the dehumidifier. I now have even humidity throughout the house. With the remote set at 45%, the RH runs between 42% and 47% in every room. The unit itself is quiet, especially with the ducting connected. I can't wait for summer, when the humidity is so high, you need gills to breathe. *The remote control is convenient. I mounted it at 60" above the floor, which is the same level as the HVAC thermostat. The screen is readable from eye level, below eye level, and from either side. It is unreadable from above. I'm 6', and I have to read it from an angle, or stoop to see straight on. If you buy the remote, consider mounting it so the tallest user can see it at eye level. BTW, the CAT 8 is backwards compatible with CAT 5a (supplied), and the 75 foot cable works fine. *There are scant instructions on hooking up ductwork. The instructions say to limit the total length of ductwork to 10 feet, but no explanation for this limitation. The instructions offer no recommendations for plumbing the unit in to the HVAC. Aprilaire has diagrams and instructions. Researching various other sites I found enough technical instruction to plumb the unit in to my HVAC. *There are auxiliary electrical connections on the cabinet, but the manual doesn't say anything about them, other than to illustrate their presence. *The controls give you the option of running the unit continuously. I'm guessing this means the fan will run continuously, and the dehumidification function will cycle on as needed. I'm pleased with the dehumidifier. Our home is so much more comfortable! The user manual could stand some improvement. The first photo is the installation into my HVAC system. The next photo is the remote viewed at eye level (with me crouching to view). The next photo is the screen when it is below eye level.
Review: Great Heavy Duty Commercial Dehumidifier! - This is a great commercial dehumidifier! It is Energy Star certified, and will remove 55 pints a day. The outside is made of a metal casing that holds up great in more rugged conditions. This is a heavy dehumidifier and reduces moisture and minimizes odors. I purchased this to go in the crawl space of our home to help with moisture. It’s a great size for what I need and easy to use. Nice functioning machine.

## Questions & Answers

**Q: Why should i buy such expensive dehumidifier ?what benefit?**
A: Most of the consumer units on the market have the same internal system made by a company that doesn't seem to care about quality.

I found these units, when used in a basement that has a humidity problem, last no more than 18 months before dying.

And even with 5 year warranties and buying from a local box store, it was a pain to find service - in or out of warranty.

So I buy these sort of industrial units.   They cost three times more than the cheap ones, but work better, are more reliable, and actually run longer than the warranty.

So if you are strapped for cash, buy the cheaper units.   You will buy three to five of them in the same time that the industrial unit will run.   And the will cost you more in terms of energy.

The consumer units, having a "catch bin" are also larger, harder to move, and nosier.   You plumb this one once, and your only concerns are cleaning, as with any unit.

**Q: What is the Warranty terms?**
A: 1 year from date of purchase - free of defects in workmanship and materials; 3 years from date of purchase  - refrigeration circuit; 5 years from date of purchase - compressor, condenser and evaporator.  We have a seasonal property and I purchased 2 of these units because of the pump and also being more of a commercial unit.  One is in the crawl space and the other is in the living quarters.  Well pleased.

**Q: What are the energy efficiency of those units (L/kwh)?**
A: They are real Energy saving dehumidifiers,Sentinel HD55 current only 3.6A with COP
 2.4L/Kwh,Sentinel HD90/HDi90 current only 5.56A with COP 2.88L/Kwh

**Q: Is there a 230V 50Hz model?**
A: We can Both Offer 115V/60HZ Mode and 230V/50HZ Mode, and Ship to worldwide. we usually offer 115V mode when you are in the USA, Let us know when you are requesting 230V/50Hz Mode before Purchase.

### ⭐⭐⭐⭐⭐ A great little package with big service!
*by G***E on November 19, 2025*

This little dehumidifier punches way above its size! It’s kept my basement dry for over four years—far better than any big-box unit I’ve owned. I did have two control boards go out, but Alorair’s customer service was exceptional and replaced them long after the warranty. Fast fix, great performance, and even better support. I’d gladly buy from Alorair again.
