Design
The body measures 12 x 21 x 12 inches and weighs 65 pounds.
Santa Fe rates its sound at 58 to 63 dB from 6 feet away.
Controls
A single knob sets humidity from 20% to 80%, and a switch controls the fan.
It works down to 49 degrees F; below that, auto defrost melts any ice before resuming. It restarts on its own after a power outage.
Placement Tips
In a crawl space, set the unit level on a vapor barrier, blocks or a hanger kit, away from standing water, with clear space around the intake and outlet. Run the drain hose with a steady downhill slope, or route the pump line to a sink, sump or exterior opening.
Seal vents and lay a vapor barrier first. A dehumidifier in a vented crawl space spends its effort drying outdoor air.
Running Costs and Care
Check the filter every month or two during heavy use and rinse or replace it when dirty. Make sure the drain line stays clear and, on pump models, test the pump occasionally.
Set the humidity target around 50% to 55%. The compressor then cycles off once the space is dry, which keeps running costs down.
How It Compares
Against the ALORAIR HD55S, the Santa Fe is the professional-channel option with proven cold-weather operation, at several times the price.
Against the AprilAire E070, both are premium crawl space units; the Santa Fe adds auto restart and a simpler knob control.
