Santa Fe Compact70 Dehumidifier

The Santa Fe Compact70 was formerly known as the Santa Fe Compact 2. The dehumidifier paired with the ATMOX Controls offers the best crawl space moisture control system. The ATMOX ACE Controller will determine the best tool to reduce excess moisture at any given time. This means that most of the time the system will be using outside fresh air pushed and pulled in with fans. The dehumidifier acts as a back up for drying action when outside air is not available. In addition, use of internal fans in the crawl space will improve the air flow to the drying unit. This will better dry all corners and areas of your space more evenly. You don’t want to dry out the area near the dehumidifier but neglect the other parts. Both vented and encapsulated crawl spaces can benefit from the use of an ATMOX system.

How do crawl space dehumidifiers work?

A dehumidifier works almost like a mini air conditioner. An internal fan pulls the warm moist air into the dehumidifier. Then, that air is cooled down. (If you think back to middle school science, you may remember that cold air can hold less moisture than warm air.) That cold air can no longer “hold” the moisture. Therefore, the moisture condenses out of the air and becomes water that is pumped out of the unit. The drier air blows back out of the dehumidifier into the crawl space. The dehumidifier will continue to run and cycle air through it until it receives a signal to stop. In most cases, the operation stops when the measured air drops below its target humidity.

Energy Usage

The goal of an ATMOX moisture control setup up is to improve energy efficiency and air quality.  We believe moisture control systems should be effective as well as inexpensive to operate. However, dehumidifiers often have high energy usage. With use of the ACE Controller, it reduces the use of the dehumidifier when fans are better at drying. As a result, there is less energy consumption and also brings in some fresh outside air.


The design of the Compact70 is for crawl spaces and tight basements. Its compact size of 12″ x 12″ x 21″ makes it easier to get in and move around in small spaces. It has a large capacity water removal of 70 pints per day. By design, it runs well in relatively low temperatures. In addition, it has an auto restart which allows it to automatically restart after a power outage.


Optional accessories for this Santa Fe Compact70 include a condensate pump kit, hang kit, and Merv-13 air filter. These are sold separately from the Santa Fe products. The condensate pump drains condensation for the SantaFe Dehumidifiers. This pump allows for drainage when gravity is not available. Therefore, the pump allows flexibility as to where you install your drying unit. Also, you can use the hang kit to mount the unit to the floor joists. This will keep your unit off the ground in a crawl space.

Relay Kit

The relay kit allows an ATMOX crawl space controller to control the operation of a dehumidifier. The kit connects to the controller with the included low voltage wire to receive its signals to turn on and off. The drying unit plugs into this relay kit, and the kit plugs into a standard electrical outlet.
