Shock-freeze systems
Planning / Implementation / Main components |
compressor from Bock Kältemaschinen GmbH in refrigeration systems for the food sector |
Refrigerant |
carbon dioxide (CO2) |
System start-up |
first plant in 1993 |
The trend towards natural refrigerants has arrived in the industrial sector - and particularly in the food sector. Years ago, innovative system developers called on Bock to develop a series of compressors for use with carbon dioxide, in addition to its standard compressors and compressor series for ammonia. |
|
Demands |
Reduce energy consumption while increasing the freezing speed of shock-freeze plants in the food sector, thereby improving product quality. Ensure temperatures of -40°C to -50°C in the shock-freeze room. |
Solution |
Refrigeration system in cascade arrangement with carbon dioxide used as the refrigerant in the low-pressure stage. |
Technical data:
Type of facility |
cascade circuit, direct evaporation, |
Refrigerant |
CO2 in the low-pressure stage |
Refrigerating capacity |
various capacity sizes, up to approx. 500 kW at an evaporation temperature of -50 °C (parallel cascade arrangement) |
Special features / Comments |
To date, more than 30 plants using this technology have been installed and taken up into operation in Germany. |
