Cooling systems from -100 up to 150 °C
LAUDA Heating and cooling systems from the line of process cooling systems in the SUK model series always consist of the compressor, pump, expansion tank, evaporator and condenser modules. Depending on the lowest operating temperature, single-stage (down to -35 °C) or two-stage compressors (down to -50 °C) are used and with very low temperatures two cooling circuits are used in cascade (down to -100 °C). The condenser can be cooled by water or air. The output is continuously and precisely controlled by the injection controller. If multiple compressors are present, stage switching saves energy and ensures low-wear partial load operation (automatic compressor system). With an electric heater or a steam heat exchanger the SUK model series can be expanded for temperatures from -100 up to 150 °C. Also precooling using in-house brine or air can be easily realized using the building kit. The application itself dictates whether a cold storage buffer tank is advantageous or not.
