PHOENIX G, Air cooled chillers

Air conditioning systems

Process cooling solutions Compressed air & gas treatment

Air cooled chiller

Nominal cooling capacity 263 ÷ 1364 kW.

The chillers of the PHOENIX G series, with R513A refrigerant, represent the best solution for centralised hydronic air conditioning for medium and large areas (such as airports, shopping centers, cinemas, etc.) ensuring energy savings levels in accordance with ErP EcoDesign directive. The screw compressors installed on PHOENIX G chillers are developed and optimized for R513A, and thanks to the "Smart Stepless" software algorithm they are capable to deliver the right cooling capacity according to the request of the system, even in situations of high load variability.

Condensing units are modular, allowing the fans to stop gradually as a function of the instantaneous thermal load, helping to increase seasonal energy efficiency of the units. The management of the units is entrusted to a control microprocessor which manage in total autonomy all main functions, including adjustments, the alarms and the interface with the outside.
