The AlorAir Sentinel HDi120 is a crawl space, basement and whole-home dehumidifier that steps up from the HDi100, with a built-in condensate pump. It removes 120 pints of water a day at AHAM conditions (80°F, 60% RH) and 93 pints a day at DOE conditions (73°F, 60% RH), and is rated for up to 3,300ft² with 290 CFM of airflow.
That capacity comes in the same 23.8" x 14.7" x 17.9" cabinet as the HDi100, drawing 7.8 A. It is sized for large basements, whole homes and big sealed crawl spaces, where the Sentinel HDi120 can be ducted at both ends and left to hold humidity on its own humidistat.
Features
120 Pints a Day at AHAM
Removes 120 pints a day at 80°F and 60% RH, and 93 pints at 73°F and 60% RH, with 290 CFM of airflow from a rotary compressor.
Covers Up to 3,300ft²
Sized for large basements, whole homes and extensive sealed crawl spaces, on a 7.8 A draw from a 15 A GFCI circuit.
Built-In Condensate Pump
Pumps water out through the drain hose automatically, with a Drain button to empty the reservoir and an E4 alarm if the pump stops.
Two-Stage Filtration
A washable MERV-1 pre-filter and a replaceable MERV-10 filter slide out of the intake side.
Microchannel Condenser
Pairs a microchannel condenser with a rare earth alloy tube evaporator, rated at 2.7 L/kWh.
Ducting on Both Ends
Inlet and supply each take 10" flex duct through optional adapters, with a 10' maximum total run. An optional wired remote on a 25' CAT 5 cable adds its own humidity sensor.
Automatic Humidity Control
Holds any setpoint from 36% to 90%, runs continuously below 36%, defrosts automatically down to 33.8°F and restarts on its last settings after a power cut.

Setup & Placement
Seal the space first: AlorAir specifies a vapor barrier and sealed vents in a crawl space. Stand the unit level on blocks or pavers rather than directly on the barrier, with 6' clear in front of the inlet and discharge. If it was tipped in transit, leave it upright for 2 hours before switching on.
Slide the compression nut over the drain hose, push the hose fully onto the fitting and tighten the nut, then route it to a drain, sump or outside. For ducted installs, keep the total duct run within 10'. Plug into a grounded 15 A GFCI circuit.
