The AlorAir Sentinel HDi65S is a compact crawl space dehumidifier with a built-in condensate pump. It removes 55 pints of water a day at AHAM conditions (80°F, 60% RH) and up to 120 pints a day at saturation (90°F, 90% RH), covering spaces up to 1,300ft² on a 4.1 A draw.
Its low, 13.3"-tall steel cabinet fits under floor joists in crawl spaces and the unfinished side of a basement, where it can stand on its adjustable feet or hang from a kit. Pump the condensate up to 19.6' to a drain, or drain by gravity, and the Sentinel HDi65S holds the humidity you set through the damp seasons.
Choose the standard model, or the WiFi model to check and adjust it from the AlorAir app.
Features
Built-In Condensate Pump
Pumps water up to 19.6' through the included drain hose, or switches to gravity drainage with the rubber drain plug. A pump fault shows as an E4 code.
Fits Low Crawl Spaces
At 19.2" x 12.2" x 13.3" and 44 lbs, it slides under floor joists and stands level on adjustable feet.
Automatic Humidity Control
The integral humidistat runs the compressor only when the space is above your setpoint. Continuous mode is there for drying out after a leak.
Auto Defrost Down to 33.8°F
Automatic defrost clears ice from the evaporator coil so the unit keeps working in a cool crawl space.
Memory Restart
After a power cut, the unit restarts on its last setting without anyone going under the house.
Energy Star Certified
Rated at 2.4 L/kWh, with a rotary compressor and a rare earth alloy tube evaporator. cETL listed.
Ducting and Remote Options
Duct dry air into a finished room through the 6" supply collar. Both versions also work with AlorAir's optional wired remote on a 25' CAT 5 cable, which has its own humidity sensor.
WiFi App Control
The WiFi model connects to the AlorAir app to monitor and adjust humidity from your phone. It ships set to gravity drainage; hold the Drain button for 3 seconds to switch to the pump.

Setup & Placement
Seal the space first: AlorAir specifies a vapor barrier on the ground and closed vents. Stand the unit on blocks or pavers so it sits level and off the vapor barrier, or hang it from joists with a hanging kit (sold separately). If it has been tipped in transit, leave it upright for at least 2 hours before switching on.
Connect the drain hose to the compression fitting on the discharge end, then run it to a sump, drain or outside. Keep 36" of clear space in front of the discharge. Plug into a grounded 15 A circuit with a GFCI outlet.

About AlorAir
AlorAir Solutions is based in Chino, California, and supplies dehumidifiers, air movers and air scrubbers for crawl spaces, basements and water damage restoration. Its Sentinel line is built for permanent installation in the spaces under and around a home.
In the Sentinel range, the HS35 and HD35P cover the smallest spaces, the HD55 and HD55S cover mid-size crawl spaces alongside the HDi65S, and the HDi90, HDi100 and HDi120 handle larger crawl spaces and basements. For restoration jobs, the Storm LGR series is built to be carried from site to site.
