Modular Construction - Two main heat exchangers, an air-to-air and a refrigerant-to-air, are made up of a stack of individual coils with a common header at each end. Each double tube coil is individually fed by a refrigerant line from the expansion valve to eliminate hot spots and insure the most efficient cooling of air in the inner tube.

Heavy Duty Automatic Drain - Trouble-free, heavy-duty steel, ball float type, is externally mounted for easy monitoring and service. It can be manually checked and manually drained, if necessary.

Instruments - Full instrumentation permits complete monitoring of dryer operation under all operating conditions.

Hot Gas Bypass System - Controls refrigerant suction pressure in refrigerant-to-air heat exchanger. This allows trouble-free operation under zero load without danger of freeze-up.


Suction Line Accumulator - Included on all units 1/2 h.p. and larger; protects compressor under varying loads by preventing liquid refrigerant from returning to refrigerant compressor, which could cause damage.

Refrigerant Feeder Assembly - Refrigerant is metered in equal amounts to each coil so refrigerant effect is spread evenly throughout the entire heat exchanger system. This quality design means energy savings to you. Utilizes quick response expansion valves instead of less costly capillary tubes.

Mechanical Separator - An integral part of the heat exchanger, the mechanical separator uses the centrifugal action of the coiled tubing, baffles and velocity reduction to separate condensate from the air. This eliminates any possibility of the condensate being carried downstream.

  • Available in 115 or 220 volt versions (please specify in the order notes field in the Shopping Cart which voltage is required)
