Air cooled industrial liquid chiller Liquid chillers designed for process cooling 24/7, 365 days a year, air cooled with two refrigerant circuits and screw compressors optimized for the use of the environmentally friendly refrigerant R513A, dry expansion shell and tube evaporator and cooling capacity from 480 kW to 1627 kW. Cosmotec experience in process cooling has led to the development of this range of industrial chillers capable of meeting the wide operating limits (both ambient and user side) required by the new technologies used for energy saving. All chillers in the WSA range are characterized by high levels of energy efficiency (Class A or B) and comply with the limits required by the 2009/125/EC Ecodesign ErP 2021 Directive. The integrated Free Cooling version available for the WSA range also allows for significant energy savings, especially when installed in areas with cold or temperate climates. Available also in Low Noise version, ideal for installations near residential areas, our units maintain high performance and high energy savings, ensuring low noise. The HT version is designed for applications with high temperature water (up to +25°C) and includes screw compressors with oversized motor. The Electronic Expansion Valve (EEV) optimizes temperature and pressure of gas evaporation, increasing the efficiency at partial loads on the user side and helping to extend the operating range of the unit. The Microchannel condensers are entirely made of aluminium and expressly designed to maximize the performance of the chiller, they allow to reduce the overall dimensions and to minimize the refrigerant charge.
