Dehumidifier – Santa Fe Advance90

Item:  SF4034180



Santa Fe Advance90 Dehumidifier

The Santa Fe Advance90 was formerly known as the Advance 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 that 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 drying unit but neglect the other parts. Both vented and encapsulated crawl spaces can benefit from the use of an ATMOX System.

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. This can lead to an increase in electric bills. 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.

Features of the Advance90

The design of the Santa Fe Advance90 is for crawl spaces and basements. Its horizontal configuration of 14.5″ x 19.4 ” x 26″ and unique dual airflow outlets make it an ideal solution for small areas such as crawl spaces. It has a large capacity water removal of 90 pints per day. It features dual exhaust for better airflow. By design, it runs well in relatively low temperatures. In addition, it has an auto restart which allows the dehumidifier to automatically restart after a power outage.

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 unit. 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 unit 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 level.


Optional accessories for the Santa Fe Advance90 and Santa Fe Compact70 include a condensate pump kit and hanging kit. These are sold separately from the Santa Fe dehumidifiers. 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. The relay kit in turn plugs into a standard electrical outlet.
