Liquid chillers designed for 24/7, 365 days a year process cooling applications, water-cooled with one or two refrigerant circuits and screw compressors optimized for the use of the eco-friendly refrigerant R513A. They feature dry expansion evaporators and shell and tube condensers with cooling capacities ranging from 236 kW to 1,529 kW.

Cosmotec’s experience in process cooling has led to the development of this range of industrial chillers capable of meeting the broad operating limits (both environmental and user side) required by new energy-saving technologies. All WSW chillers feature high levels of energy efficiency (Class A or B) and comply with the limits required by Directive 2009/125/EC Ecodesign ErP 2021.

Low Noise version
Even in the Low Noise version, ideal for installations near residential areas, our units maintain high performance and significant energy savings while ensuring low noise levels. The compressor casing effectively reduces transmitted noise (-4dBA) thanks to a specific composite sound-absorbing material lining.

HT version for high-temperature water applications (e.g., plastics)
The HT version’s refrigeration circuit is specially designed (upon request) to produce chilled water with evaporator outlet temperatures from +15°C to +25°C. The compressor has an enhanced motor, allowing for broad operating limits and high suction temperature. 

Eco-friendly LOW GWP version

The WSW units are available in a low environmental impact version, which ensures a reduction in global warming potential with R513A refrigerant (GWP = 572) classified as A1 non-toxic, non-flammable, and with zero impact on the ozone layer.

Thanks to the integration of the main hydronic components (plate water/water heat exchanger, servo-operated valves, and one or more inverter-controlled pumps), the WFM module allows transforming a system consisting of a WSW chiller and a dry cooler into a free cooling system capable of saving energy. These Free Cooling systems offer significant energy savings, especially in applications requiring high cooling fluid temperatures (plastics) and installations in areas with cold or temperate climates.

The WFM module’s control software monitors both external and operating temperatures and adjusts the cooling capacity of the remote dry cooler. This ensures optimal control of the WSW unit’s condensation temperature and maximum Free Cooling efficiency during mid-seasons, with low operating costs and minimal environmental impact.
