Basic data on the eChiller – the hitherto most efficient chiller:

The eChiller is perfectly suited for cooling of industrial processes, server and switching rooms and technical building equipment

The heart of our sustainable refrigeration unit is a proprietary compressor system known as the “ct turbo”.

This is a turbo compressor fitted with an exceptionally efficient power unit comprising a motor and electronics that achieves rotational speeds up to 90,000 rpm and adapts the performance of the compressor to the cooling demand by regulating the rotational speed. It is precisely these components, which we have assembled to a highly efficient cooling unit in the eChiller, that constitute the real innovation.

The technology – trailblazing, highly efficient and climate neutral

The modular design of the system makes it possible to operate only those components needed to achieve the required temperature lift by interconnecting the cooling units as a function of the internal heat load and outside temperature.

The transitions are continious and range from two-stage, full-load capacity to single-stage operation and even a pure free cooling mode. But, unlike other conventional refrigeration systems with “free cooling” modes, eChiller’s internal passive cooling kicks in even when outside temperatures are only marginally lower than the cooling water or brine intake temperature.

Feasible chilled water temperatures start at 10 °C. As a result of the system design, cold water temperatures of 22 °C and above, which conventional cooling systems cannot work with, are especially efficient. Here, the eChiller 2-35 achieves a cooling capacity of 35 kW.
