SULLAIR Refrigerated Dryers

Refrigerated dryers remove moisture from compressed air by cooling the air — thereby reducing the ability of the air to hold moisture.


SULLAIR Refrigerated Dryers are available in the following configurations:

RN — Refrigerated Non-Cycling — 5 to 325 scfm

RD — Refrigerated Digital Cycling — 400 to 6000 scfm

RC — Refrigerated Cycling — 150 to 3000 scfm n RH — Refrigerated High Temperature — 15 to 100 scfm

SULLAIR refrigerated dryers are registered with CAGI and feature:

  • State of the art heat exchanger design n Evaporator with multi-stage separator stainless steel demister
  • Low power consumption with energy saving features including:
    • 3-in-1 heat exchanger
    • High efficiency compressors
  • Globally marketable refrigerant R-134a
  • Consistent dew point performance
  • Low pressure drop
  • Refrigerant analyzer indicator
  • Fan cycle switch
  • High quality fan motors
  • Oversized condenser
  • Removable side panels and parts for easy serviceability
