PHOENIX Z

PHOENIX Z 

Air-cooled liquid chillers featuring semi-hermetic screw compressors.

Nominal cooling capacity 332 – 1511 kW

The accurate adaptability of delivered cooling capacity ensured by the "Smart Stepless" function, combined with the use of negligible GWP refrigerant R1234ze, makes the PHOENIX Z series the perfect balance between high seasonal energy efficiency, application flexibility and environmental sustainability.

The 4th generation HFO R1234ze refrigerant characterized by an almost zero greenhouse effect, represents the green alternative to the main low pressure HFC fluids, such as R134a and R513A.

PHOENIX Z: The efficient choice with a negligible environmental impact.
