Process cooling systems

Cooling systems from -100 to 150 °C

 

Heating and cooling systems from the process cooling unit line of the type series SUK always consist of the modules compressor, pump, expansion vessel, evaporator and condenser. Depending on the lowest working temperature, single stage (down to -35 °C) or two stage compressors (down to -50 °C) are used. At very low temperatures down to -100 °C, two cooling systems in cascade connection are used. Cooling of the refrigerant condenser is done with cooling water or air. Output is regulated infinitely and precisely by injection control. If several compressors are used, an incremental switch ensures energy-saving, low-wear, partial load operation (automatic compressor control). With an electric heater or steam-heated heat exchanger, the SUK type series can be used for temperatures from -100 to 150 °C. Pre-cooling with on-site brine or air can be easily implemented using the modular system. The application alone decides whether or not a cold accumulator is beneficial.
