The AlorAir Sentinel HDi90 is a crawl space and basement dehumidifier with a built-in condensate pump. It removes 90 pints of water a day at AHAM conditions (80°F, 60% RH) and up to 198 pints a day at saturation (90°F, 90% RH), covering spaces up to 2,600ft² on a 5.56 A draw.
Because the pump sends condensate out through the included drain hose, the unit can sit wherever the space needs it rather than above a drain. The Sentinel HDi90 runs on its own humidistat, warns you with an E4 code if the pump stops, and ducts dry air into a finished room when needed.
Choose the standard model, or the WiFi model to check and adjust it from the AlorAir-C app.
Features
Built-In Condensate Pump
Drains the reservoir automatically through the included drain hose. A Drain button purges the reservoir before you move or store the unit.
Pump Fault Protection
A high water sensor stops the compressor and shows E4 if the pump stops, so water does not overflow onto the floor.
90 Pints a Day at AHAM
Up to 198 pints a day at saturation, from 210 CFM of airflow and a rotary compressor, rated at 2.69 L/kWh.
Automatic Humidity Control
The integral humidistat runs the compressor only above your setpoint, with continuous mode for drying out after a leak.
Auto Defrost Down to 33.8°F
Automatic defrost clears ice from the rare earth alloy tube evaporator, and memory restart resumes your settings after a power cut.
Ducting and Remote Options
A 6" supply adapter comes standard, with an optional 12" return collar. Both versions 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-C app, so you can monitor humidity and change settings from your phone. A WiFi light shows the connection status.

Setup & Placement
Seal the space first: AlorAir specifies a vapor barrier on the ground and sealed vents in a crawl space. Stand the unit level on blocks or pavers rather than directly on the barrier, and keep the inlet and discharge away from walls. If it was tipped in transit, leave it upright for at least 2 hours before switching on.
Slide the compression nut over the drain hose, push the hose fully onto the fitting on the discharge end and tighten the nut, then route the hose to a drain, sump or outside. Plug into a grounded 15 A GFCI circuit.

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.
The HDi90 is the pump version of the Sentinel HD90, which drains by gravity, and it shares its capacity with the HDi90 Duct-able Version. For smaller crawl spaces, the Sentinel HDi65S covers up to 1,300ft², while the HDi100 and HDi120 step up to 100 and 120 pints a day at AHAM for larger basements.
