The AlorAir Sentinel WHD120 puts more capacity into the compact WHD cabinet: 104 pints a day at AHAM conditions (80°F, 60% RH) and 85 pints a day at the DOE whole-home point (73°F, 60% RH), for homes up to 3,000ft² on a 6.8 A draw.
It shares the WHD100's 22.64" x 14.65" x 19.88" cabinet and 89.07 lbs weight, so it fits the same attic, basement and crawl space installs while covering more floor area. Ducts connect to its 10" inlet and outlet, with a 6" fresh air damper beside them.
Run the Sentinel WHD120 from the included wired controller in %RH or GPP mode, or switch it to central control from a 24 V AC HVAC signal.
Features
Ducted Whole-House Drying
10" inlet and outlet collars (included) let it pull damp air from one area and return dry air through ducts to several rooms, on its own or alongside an HVAC air handler.
Fresh Air Damper
A 6" electric damper can bring in outdoor air in step with the dehumidifier, within upper and lower temperature limits you set from the controller.
%RH or GPP Control
Set relative humidity from 35% to 90% in 1% steps, or grains per pound from 25 to 200. Continuous mode runs it nonstop for drying out.
Wired Wall Controller
The included controller on a 26' cable shows humidity and status, with a 1 to 24 hour shutdown timer, two fan speeds and a child lock.
More Capacity, Same Footprint
104 pints a day at AHAM from the same cabinet as the WHD100, with a discharge that can be turned to blow out of the back or the top.
HVAC and Pump Terminals
A 24 V AC signal on terminals A3/A4 switches it to central control, A1/A2 report its status, and A5/A6 or A8/A9 take an external condensate pump or float switch.
Memory Restart
After a power cut it resumes its last mode, humidity setting, fan speed and fresh air settings once the three-minute compressor delay has passed.

Setup & Placement
Install the unit in a fully enclosed space, level on its feet, on a platform or hung so the drain line can run downhill. Keep the inlet and outlet off walls. AlorAir asks for the unit to stand upright out of the box for 24 hours before it is first plugged in.
Connect the 10" supply and return ducts, and the 6" fresh air duct if used, then plug the wired controller into the unit with its cable. Power it from a dedicated, grounded 15 A GFCI outlet. For ducting into an HVAC system, follow one of the four layouts in the manual with a qualified installer.

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 and around the home, from crawl spaces to whole-house systems.
The Sentinel WHD series is AlorAir's ducted whole-house line. The WHD100 and WHD120 share a compact 22.64" x 14.65" x 19.88" cabinet, while the larger WHD150 and WHD200 add a pre-cooler and a second filter stage. For a single crawl space without ductwork, the Sentinel HDi and HD models or the Galaxy series are a simpler fit.
