Prosper de Mulder, the UK's largest pet food processor, had a requirement for an efficient plate freezing system to replace the old R-22 system for their pet food production facility in Doncaster, England.
Requirements
Replacement of the old refrigeration plant which used R-22 with a non ozone depleting refrigerant which would not be subject to impending F-gas regulations.
Solution
Installation of an environmentally friendly and highly efficient plate freezer syste
Technical data
Cooling capacity:
1,000 kW
Secondary refrigerant:
NH3
Main components:
Screw compressors, surge drum/pump set, 16 plate freezers
Special features:
The main environmental benefit is the low energy consump-tion of this system. The combination of CO2 with pressurized liquid defrost for a plate freezing system is a world first. Freezing times are 75 % of the traditional system and the system is running more efficiently at far lower temperatures without causing excessive power consumption.
