RHT Series

High Inlet Temperature Refrigerated Dryer

Gardner Denver RHT Series High Inlet Temperature refrigerated dryers feature a unique design which works directly with reciprocating air compressors. A unique heat exchanger allows the dryer to accept elevated inlet air temperatures, up to 180°F (82°C). This allows compressed air users to send high temperature air straight from their compressor directly to the RHT Series refrigerated dryer and maintain a 50°F pressure dew point. The RHT Series is ideally suited for auto body shops, auto service centers, and light industrial facilities with 5 to 30 horsepower reciprocating air compressors.


  • Stainless steel heat exchangers with high heat transfer coefficients allow inlet temperatures to 180° F (82° C). All models feature air-to-air and air-to-refrigerant heat exchangers.
  • Adjustable timed electric drain—valve open and closed time—reliably discharges condensate from the dryer

  • Widely spaced Inlet/Outlet connections, flow direction stamped into cabinet, for ease of installation and filter mount

  • Instrumentation with lighted compressor On/Off switch, dew point temperature indicator and fault light

  • Top mount fan, upward condenser air flow allows installation in tight spaces

  • Bottom base rail with pre-drilled mounting holes for secure floor mount
  • Quick release front panel for ease of access to dryer internals for routine maintenance
