The units are designed to operate with conventional group A1 HFC refrigerants, depending on the compressor type and operating conditions. Depending on the type of refrigerant used, the range of evaporation temperatures is from -50 °C to +20 °C. For higher evaporation temperatures and / or higher ambient temperatures, the units are equipped with a larger condenser for trouble-free operation. The units are supplied with a protective inert gas fill.
