Air-cooled liquid chillers - Basic acoustic configuration 382 ÷ 1945 kW

Nominal cooling capacity: 382 ÷ 1945 kW

Refrigerant: R513A low GWP

Designed for liquid refrigeration in medium and large industrial processes, with high energy efficiency in compliance with the ErP EcoDesign directive. Thanks to variable speed inverter technology, the screw compressors modulate the cooling capacity according to the load, optimising energy consumption even in the presence of temperature variations.

Main features

• Low GWP R513A refrigerant, environmentally friendly and compliant with environmental regulations.

• High seasonal efficiency (SEPR HT).

• Inverter technology and Step control logic for flexible adaptation to all operating conditions.

• Wide range of operating limits, even in critical conditions.

• Complete safety, with continuous monitoring of compressors, oil level, HP/LP pressure switches, phase monitor and crankcase heaters.

• Modular condensing section, with fans that can be progressively stopped to optimise consumption.
