A process chiller is a refrigeration system using halocarbon or ammonia refrigerants that provide cooling for a process or industrial application. Since Welltech Cooling Towers,only offers refrigeration systems, we will describe that type only. A refrigeration circuit consists of compressor(s), condenser(s), thermal expansion valve, and evaporator(s), at a minimum. Together, these components remove heat from a process load to provide consistent setpoint temperatures 24 hours a day, seven days a week. Process chillers are designed for the most rugged environments and conditions unlike commercial or HVAC chillers.It’s combined large buffer tank with integral unique coil and in-tank evaporator design has been adapted for varying load and flow conditions whilst minimising pressure drops.What’s more, it’s minimal footprint will help you save space and commissioning is simple with fast delivery of standard units – enabling you to capitalise on your process cooling immediately.

Components of Process Chillers

Process chillers are made up of many different parts depending upon the design. Each process chiller incorporates a compressor, condenser, evaporator, pumps, pipes, high pressure refrigerant relief valves, and possible cooling towers, tanks, filters, and fans. Contact Welltech Cooling Towers and one of our technical engineers will help you design one to meet your custom needs.

How Process Chillers Work

A process chiller may use an air or water condenser in its cooling process. As the subcooled liquid refrigerant passes from the condenser to the evaporator, a thermostatic expansion valve causes the pressure and temperature to drop. The refrigerant then picks up the heat from the fluid flowing through the evaporator, changing from a liquid to a vapor. It flows in a continuous cycle continually cooling the process.
