The thermoforming food packaging firm, part of the Faerch Plast Group, has had Aqua Cooling design a bespoke and future-proof chiller system to replace its ammonia chiller technology.
Aqua supplied to the Anson site two 700kW and two 800kW air-cooled, thermosyphon free-cooling Turbocor units working on R134a refrigerant.
The system design spreads the cooling load, ensuring that optimum cooling and ultra-high efficiency levels are achieved at all times. The compressors are most efficient when operated under part-load. Additionally, the system has full built-in redundancy: if there should ever be a malfunction, the process will maintain full cooling. The system also enables free cooling to be achieved in a higher ambient temperature than normal.
Aqua said overall electrical running costs are now 60% more efficient compared with traditional scroll compressors that have integrated free cooling.
Faerch Plast said through the Turbocor technology, the site can now achieve maximum efficiency at a reduced load, and eliminates the need for excess machinery on standby in case of servicing or faults, which was always seen as a waste of investment.
