eChiller Chilled Water Units
The eChiller is designed for cooling processes with high chilled water outlet temperatures. Its optimal cooling capacity lies in a range from 16 °C to 22 °C, but outlet temperatures of between 10 °C to 28 °C are also possible – a spectrum that traditional chillers are only partially capable of covering.
The eChiller is available in four designs, with a nominal cooling capacity range of 20 kW to 45 kW, depending on the configuration of the chilled water outlet temperature, the compressor and the cooling water inlet temperature. Total capacity can be scaled to over 300 kW by combining several systems.
The standard equipment for easy integration into your application
The following diagrams describe the areas of application of the two versions. As described in diagram “Type 35”, for the required chilled water outlet temperature of 18 °C a maximum permissible cooling water inlet temperature of 40 °C is shown. The dark colored area marked “I” describes the optimum areas of application. The areas “II” are available on request. The lower diagram shows the efficiency characteristics of the respective systems as a function of the chilled water outlet- and cooling water inlet temperatures. The example “Type 35” shows an EER of “8” for a required chilled water temper-ature of 20 °C and a cooling water temperature of 25 °C.
