REFRIGERATION SYSTEM WITH TWO-STAGE COMPRESSION 

• Compression refrigeration system with two-stage compression to achieve particularly low temperatures. 
  
• The two compressors are connected in series, with each compressor only having a relatively low pressure ratio. 
  
• The unit represents the refrigeration cycle process in the p-h diagram. 
  
• The unit contains hermetic low and high pressure compressors and adjustable intercooling via refrigerant injection 
  
• Heat exchange for additional super-cooling of the liquid refrigerant closed refrigeration chamber contains evaporator with fan and adjustable electric heater as cooling load 
  
• Digital display for temperatures, drive power of the compressors and cooling load power 
  
• Power consumption: about 550W  
  
• Refrigeration capacity: 1700W at -10°C' 
  
• 230V, 60Hz, 1 phase 
  
• Unit complete with all required accessories.
