EKSC series screw-type water cooled chiller fetures a leading-edge total heat recovery technology, the
Condenser has a built-in heat recovery device with a high efficiency. This reduces the heat load in the condenser, improves heat exchange and cooling efficiency of the unit, and minimizes energy consumption.
The heat recovery device is built inside the condenser, and does not increase the dimensions of a unit. It is highly corrosion-proof, and can provide clean and sanitary hot water.

Note:
1. Working conditions for nominal cooling capacity: inlet/outlet water temperature in the evaporator: 12/7°C; inlet/outlet water temperature in the condenser 30/35°C.
2. Working conditions for nominal heating capacity: water flow in the above table; inlet/outlet water temperature in the condenser: 40/45°C; inlet/outlet water temperature in the evaporator 15/10°C (note: antifreeze is required when water temperature in the water circuit is lower than 3°C in winter).
3. Working conditions for nominal cooling + total heat recovery capacity: inlet/outlet water temperature in the evaporator ~/7 °C; inlet/outlet water temperature in the condenser 40/45°C.
4. Heating capacity parameters in the table are measured only for heat pump units. Cooling only units do not have this parameter.
5. In the parameter table, parameters marked with "cooling + total heat recovery*" are applicable to only to total heat recovery units, and are not applicable to cooling only or heat pump units.
6. The pressure drops of evaporators and condensers do not include resistance from external water pipes and parts.
7. For on-site electric wiring, see the name plate or installation menu of the unit.
