Water chiller WSA/WSI ErP Techno

for screw compressorshigh-performancefree cooling

WSA is a range of air-cooled liquid chillers featuring high efficiency and low environmental impact with free-cooling technology and cooling capacities from 280 to 1860 kW. Designed for 24/7, 365-day-a-year process cooling applications, the new WSA – WSI liquid chillers are characterized by one or two refrigeration circuits with stepless screw compressors (WSA) / inverters (WSI) and use plate or shell and tube evaporators with dry expansion and high heat exchange surface. The WSA/WSI range is characterized by high energy efficiency levels (Class A or B), complying with the limits required by Directive 2009/125/EC Ecodesign ErP 2021. Thanks to the special W-shaped configuration of the microchannel heat exchangers and their sizing, it was possible to achieve specific power levels (kW/floor area) at the top of the category. HT Version for High Temperature Water Applications (e.g. plastic) The HT version’s refrigeration circuit is specifically designed to produce chilled water with evaporator outlet temperatures from +15°C to +25°C. The compressor has an enhanced motor, allowing wide. Even in the Low Noise version, ideal for installations near residential areas, our units maintain high performance and significant energy savings, ensuring low noise levels. The compressor housing effectively reduces transmitted noise (-4dBA) thanks to a specific sound-absorbing composite material coating. Chiller LT version for Ambient Temperatures Down to -20°C Thanks to a sophisticated condensation control system based on partialization of the condensation surface and control of EC fan speed, the CHILLER LT version can operate in ambient temperatures as low as -20°C
