Requirements
The operator attached great importance to the refrigeration that should be economical and sustainable.
Solution
At the heart of the facility is a machine room with ammonia refrigeration units that chill cold water to a temperature of just 2°C by cooling the ammonia, which has a total refrigerating capacity of 8,000 kW, and evaporates at 0°C. The coolant is distributed to the various users via a network of pipes, where it absorbs the heat generated by the manufacturing processes.
