The Santa Fe Rx operates much more quietly than the Santa Fe, making it an ideal choice for offices, residences, schools, and libraries. The smooth white cabinet creates a versatile dehumidifier that is suitable with any decor. The internal condensate pump and 20 feet of drain hose add extra convenience, allowing you to direct water outside or to a suitable sink or drain. Extremely efficient, the Santa Fe Rx removes more pints of water per kilowatt of electricity than most other residential dehumidifiers. The Santa Fe Rx, if desired, provides a secondary filter housing which can be connected to the back. This housing can hold your choice of HEPA, carbon plus pleated media, or high efficient (95%) filters, all of which remove dust and other airborne allergens. Santa Fe Rx features a free-standing design provides high efficiency humidity control and air filtration to areas up to 2,200 square feet.

The Santa Fe Rx utilizes refrigeration to cool the incoming air stream below its dew point as it passes through the dehumidification (evaporator) coil. This cooling results in the removal of moisture (latent heat) and reduction of the temperature (sensible heat). The cooled and dried air is used to pre-cool the incoming air stream resulting in up to a 200 percent increase in overall efficiency. After the pre-cooling stage the processed air is reheated by passing through the condenser coil. The latent heat removed by the evaporator coil is returned to the air stream at this stage as sensible heat, resulting in an overall increase in temperature from the incoming air.


  • The standard air filtration is provided by a pleated polyester and cotton blend media filter located at the air intake at the top of the unit. The efficiency rating of this filter is 40% in the ASHRAE 52-76 Dust Spot Test.
  • The optional HEPA filter is a micro-glass paper mini-pleat filter located in a special housing mounted on the back of the Santa Fe Rx cabinet. The efficiency rating of this filter is 99.97% on the D.O.P. test.
  • The Santa Fe Rx is controlled by a dehumidistat with positive "ON" and "OFF" settings and a variable setting range from "20%" to "80%".
  • The Santa Fe Rx has a built-in defrost system that is designed for operation down to 55°F - however, unit is designed to run in environments 70°F and higher.
  • The unit contains a blower switch that permits continuous blower operation for filtration, independent of dehumidification.
  • The Santa Fe Rx is portable and provided with four casters.
  • The unit contains a condensate pump and 20 feet of drain hose.
  • The wiring of the unit is through a factory installed six foot power cord; 115 volt with ground.
