Multiple scroll compressors and R410A contribute to the energy efficiency of these compact units, which have a small footprint and low noise levels.

There are versions of Tetris chillers with 26 sizes offering cooling capacities from 110 to 930 kW. Options include heat pump, integrated hydraulic module, total or partial heat recovery and free cooling.

Further energy efficiencies are achieved with options such as electronic expansion valves and EC (electronically commutated) axial fans, providing up to 15% energy savings per fan, as well as less noise and finer control of air flow.
