ENGIE Refrigeration GmbH has launched its new air-cooled QUANTUM Air chiller series.

In total, there is 28 versions of the new series. The company said 14 of these models use the refrigerant R-1234ze, and 14 models use either the refrigerant R-134a or R-513A.

The new air-cooled QUANTUM Air has achieved much higher levels of efficiency, this has been achieved through intelligent connections between the different components.

Second, the QUANTUM Air makes more efficient use of operating fluids, as the refrigerant fill level has been reduced significantly.

The size of the chiller has also been reduced without affecting its performance.

QUANTUM Air achieves a refrigeration capacity of between 250 kilowatts and two megawatts for the first time.

This means the chiller outperforms not only its predecessor model, but all air-cooled chillers with magnetic-bearing compressor technology that are currently available on the market.

Another special feature is its modified control system, which facilitates improved control and regulation options that are optimised in terms of energy efficiency.

Furthermore, it enables even better adaptation to customer-specific cooling requirements at every operating point and at different ambient temperatures.

Each model offers the optional Supersilent package, which incorporates additional noise-reducing measures – an essential aspect, especially for noise-sensitive applications in hospitals or office buildings, for example.

If needed, customers can also choose preconfigured hydraulic modules – i.e. pump units with a frequency converter – and integrated free cooling modules for free cooling, mixed mode or compression mode.
