WKS series.
Up to 68.1 kW
refrigeration capacity.
Active water coolers for all types of industrial applications.
The face of future cooling!
The WKS family now offers you water chillers with a cooling capacity of up to 68.1 kW. The WKS series is ideal for all kinds of industrial applications, e.g. laser machine tools, plastics and packaging industry, printing, food and beverage.
Thanks to the use of an innovative refrigerant with a GWP (Global Warming Potential) of <650, the WKS series sets you up to meet any future requirements. The result: Up to 50 % less refrigerant than on previous models with similar capacity.
- Developed for use in a wide range of areas. Ideal for all kinds of industrial applications, e.g. laser, machine tools, plastics and packaging industry, printing, food and beverage. Whenever precision cooling is required.
- Wide range of customisation options. Based on standardised products, you can choose customisation options to make our WKS products perfect for your specific cooling requirements.
- Short delivery times. Standardisation ex works and the modular design result in quick availability.
- Installation options. The variable air suction side either from the right or from the left side ensures flexible positioning of the units in the room.
- Intelligent. Thanks to smart engineering, the product can be tested during operation by a service technician. The result: No failures or unnecessary downtimes.
- Dependable. All models comply with the currently valid EC directives, standards and regulations: ISO 9001, EN 378, VDE and BGV.
- All-inclusive package. Our service doesn't end with the delivery and commissioning of your system. With maintenance packages tailored to your needs, we ensure that your system continues to perform its tasks problem-free for many years.
- Logistics. Thanks to a refrigerant filling of <12 kg and a non-flammable refrigerant, the units can be transported by air freight with no problems.
- Usable worldwide. Thanks to bifrequent design (3 Ph / 400 V / 50 Hz, 3 Ph / 460 V / 60 Hz).
