WSW Techno

Water Cooled Industrial Chiller

Water Cooled Industrial Chiller

Liquid chillers designed for process coolin 24/7, 365 days a year, water cooled with one or two refrigerant circuits and screw compressors optimized for the use of the environmentally friendly refrigerant R513A, dry expansion evaporators and shell and tube condensers and cooling capacity from 230 kW to 1530 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 the chillers in the WSW range are characterized by high levels of energy efficiency (Class A or B) and compliance with the limits required by the  2009/125/EC Ecodesign ErP 2021 Directive.

The HT version is designed (on request) 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.

 

Eco-friendly LOW GWP version

WSW units are available with environmentally friendly R513A refrigerant that provides a reduction in global warming potential (GWP = 572). Rated A1 R513A is non-toxic and non-flammable.

Free Cooling thanks to WFM module

Thanks to the integration of the main hydronic components (plate-type water/water exchanger, servo-controlled valves and one or more inverter-controlled pumps), the WFM CyberCool Free Cooling Booster module makes it possible to transform a system consisting of a WSW chiller and a drycooler into an energy-saving free cooling system.

These Free Cooling systems provide significant energy savings, especially in applications requiring high cooling fluid temperatures (plastics, data centers) and installation in areas with cold or temperate climates.

The CyberCool Free Cooling Booster control software monitors both outdoor and operating temperatures and adjusts the cooling capacity of the remote dry cooler: this ensures both optimal control of the WSW unit’s condensing temperature and maximum Free Cooling effectiveness during mid-seasons, with low operating costs and minimal environmental impact.

Depending on the outdoor temperature, the most efficient mode is automatically selected throughout the year, whatever the local temperature profile.

  • Compressor Mode (DX): the heat load of the utility is met by the WSW refrigerant circuit.
  • Mix Mode: at mild temperatures, the WSW operates energy-efficiently in Mix Mode, a combination of Free Cooling and mechanical cooling with compressors to reduce energy consumption.
  • Total Free Cooling: at low outdoor air temperatures, the fluid is completely cooled by the ambient air and the compressors are turned off. Energy consumption is minimized by operating only the variable speed fans of the drycooler.

 

Due to its characteristics, the use of WSW Techno is particularly suitable in the following applications:
