ARIES G, Air cooled chillers

Air cooled chillers.

Nominal cooling capacity 228 - 1303 kW

The ARIES G chillers are the best solution for process cooling applications (such as automotive, plastic, chemical and pharmaceutical, food and beverage, wineries, machine tools, etc.), offering a large energy saving in all the functioning conditions. The design philosophy is strongly oriented to reduce the operating costs and to protect the environment with the introduction of the low GWP refrigerant R454B. The main characteristics of this range are: scroll compressors for a higher seasonal energy efficiency, high efficiency shell and tubes exchangers to perform in more suitable energy saving conditions and total heat recovery for sustainable use of absorbed electricity. The wide range of accessories and versions offers solutions to the most different installation requirements and at the same time facilitating installation, start-up and management of the system.
