Process chillers are refrigeration systems, which use coolants like halocarbon and ammonia for industrial applications. The main components in these cooling systems are the compressor, condenser, evaporator and thermal expansion valve. All of these work together to move heat away from a process load, as consistent temperatures are important. These have to be maintained 24/7. These chillers are built to work and weather extreme conditions unlike regular commercial chillers available on the market. To learn more about these equipment, here’s a brief discussion from Smart Cooling Products:

Multiple Industrial Uses

Process chillers are used in a number of industries. These include plastic industry for injection and blow molding, baking and food industry to make chocolate and process vegetables and meats, pharmaceuticals, printing, aircraft manufacturing, metal finishing, chemical industry, laser cutting machines, dry cleaning and others. They’re available in two categories – compact and central. Process chillers use air or water condensers for cooling. Refrigerants pick up heat from the fluid in the evaporator and change it into a vapor. These chillers work continuously to keep temperatures at a particular point depending on need.

Regular Inspections

For them to work at an optimal level, quarterly inspections are needed. Routine check for leaks, checking compressor to see that operating pressures are within range, and motor amps and voltage have to be checked. All electrical points in starts, relays and contractors also need checking. This is done to make sure there’s no tripping or burnt out circuits. Daily checks have to be done as well to shut off unused chillers. Assessment of condenser coils is also important, especially if the chiller is being used round the clock. Control functions for gas bypass and liquid injections have to be checked as part of the routine maintenance.

Annual Maintenance Checks

Annual maintenance checks are also necessary, so that oil changes can be done. Checking oil heaters and other valves will help ward off trouble and fix leaky areas. Depending on the size of the application and the process chiller, systems can be placed right next to the equipment or at another location. These can be designed and set up by manufacturers for seamless process functioning.
