HL X Series
Low-ambient air-cooled chillers with R32 refrigerant, operating in ambient temperatures down to -20°C.
The HL X Series is built for demanding environments, operating reliably in ambient temperatures from -20°C to +43°C. Using low-GWP R32 refrigerant, these chillers pair a stainless steel plate heat exchanger with a large integral stainless steel water tank and centrifugal pump, making them ideal for year-round outdoor installation in colder climates.
Capacity Range: 20.4 kW – 58.9 kW
Operating Range: Ambient: -20°C to +43°C | Water outlet: -5°C to +35°C
