HFO refrigerant R1234ze has low GWP and meets the strictest environmental requirements. However, at the same time, it comes with specific safety requirements of the class A2L. Our chillers can be built in the classic version with piston reciprocating compressors, or semi-hermetic screw compressors, or in an oil free version with Turbocor compressors and flooded evaporator. Chillers can be built in an indoor or outdoor version. On top of that, we can offer a special version of a built-in marine container in order to fully achieve a plug-and play solution.
