air cooled screw chiller Rhoss

Klima-Therm’s wide range of air-cooled screw chillers offer between 300 and 1,700kW of cooling by employing semi-hermetic screw compressors. A variety of refrigerants are available from traditional HFCs to more modern low and ultra-low GWP alternatives.

Equipped with fixed speed or inverter-driven compressors, these reliable chillers with optional hydronic systems are available for quick despatch to suit your project deadline.


All our air-cooled screw chillers are ErP 2021-compliant, achieving outstanding EER values to reduce operating costs while, at the same time, improving building occupants’ comfort and wellbeing.

Units are available with a sound power level as much as 10dBA lower than standard chillers for whisper-quiet performance in noise-sensitive applications.

They are available for process cooling, allowing flexible water temperatures as low as -10°C with operations down to -20°C outdoor temperature.


A soft starter option can reduce the load and torque in the power train and electric current surge during start up to extend the life of the units and master/slave sequence control makes multiple chiller configuration possible.

With pre-painted coils for marine and seaside environments, the chillers can also include hydronic modules with pump, double pumps or tank and pump set up, gas leak detection, power factor correction, compressor shut off valves, building management system connection and a desuperheater as well as a 100% heat recovery unit.
