country and have been a major part of the drive to apply the latest technologies . The client brief of the project was essentially to supply Cooling as a Service ( Caas ) at the most economical price . The client requirement also included a steam contract for outsourced steam with heat recovery from the refrigeration plant for hot water generation . The ownership of the refrigeration plant would remain with Energy Partners .
The plant provides cooling to the new meat processing facility for cold storage , process cooling , climate control in the process areas , and spiral freezers . The design cooling capacity is 2200kWR high stage , and 1320kWR low stage .
The MT Bitzer ammonia compressor racks .
THE INSTALLED REFRIGERATION PLANT SYSTEM The plant is a two-stage ammonia plant with direct pump circulation to the spiral freezer , freezer rooms and chiller rooms .
A secondary glycol system has been installed for the climate-controlled areas and product cooling . Waste heat recovery from the compressor oil cooling is used to heat the 200kl hot water tank for wash water .
Fresh air supply and ventilation systems have been installed for the high-risk areas and medium risk production areas .
Notably for this project was the selection and installations of the latest Bitzer ammonia compressor packs ( ACPs ) that have been designed specifically for ammonia
