The SPRPN-Series Pro non-cycling compact refrigerated air dryers from Sullivan-Palatek operate by directing hot air containing moisture through an air/air heat exchanger. These dryers have a capacity range of 10 to 480 CFM at 100 PSIG.
The models 10-150 are offered in 115/1/60 voltage, while the sizes 175-480 are available in 230/1/60 voltages.
Features
Heat Exchanger Module
– Consists of air/air and air/refrigerant heat exchangers and a high-performance separator.
– Designed to facilitate efficient heat transfer and separate condensate.
Refrigerating Compressor
– Hermetically sealed and gastight units.
– Equipped with integrated safeguards to prevent overheating and excessive current.
Condenser
– Responsible for cooling and liquefying gas from the compressor.
– Must be kept free of dust and impurities for optimal functionality.
Filter Dryer
– Absorbs moisture within the refrigeration cycle.
Capillary Tube
– Made of copper and reduces refrigerant pressure.
– Optimizes evaporation temperature.
Hot-Gas Bypass Valve
– Helps maintain a constant evaporation temperature and pressure.
– Achieves this by diverting hot gas during partial load situations.
