Product information "eChiller Turbo Compressor Recirculating Chillers"
Cooling Capacity up to 120 kW
The eChillers are the ideal solution when chilled water of 10 to 25°C and cooling capacities of up to 45 kW are needed. The refrigerant is water, R718. Steam is compressed in vacuum by a turbo compressor, condensed in a water-cooled condenser, expanded in the expansion device and evaporated in the evaporator.
The smaller eChillers are available for 35 kW (eChiller35 ) and 45 kW (eChiller45 ) of nominal cooling capacity and with single or double stage compressor units. The single stage is used for low ambient temperatures (hot side cooling water max 32°C) whereas the double stage is used for higher ambient temperatures (hot side cooling water max 45°C). The eChillers are installed in a cabinet of width 1300 mm, depth 700 mm and height 1980 mm and have a dry weight of 510 kg. When installed they need to be filled with 60 liters of tap water – it is that simple. A bigger eChiller with a single stage and 120 kW of cooling capacity will be available in 2021 (eChiller120 ).
The eChillers have connections to the cooling water side and to the chilled water side. Cooling water/coolant can be facility water or a glycol-water loop with outside air blast cooler/heat exchanger. The chilled water loop can be equipped with a buffer tank which increases the operating capacity range from 50-100% to 20-100%
