Industrial chillers are typically used as closed-loop systems for complete packaging, including hot and cold water units, condensers and circulation pumps, expansion valves, no-flow shut-off, internal cold water tanks, and temperature control stations. Internal tanks help maintain cold water temperatures and prevent temperature spikes. The closed loop industrial chiller recirculates at constant temperature and pressure, increasing stability and repeatability of water cooling equipment and instrument cleaners with conditional addititives or clean water. Cool the water flow to the angle of application and use the back.

If there is a high temperature difference between the two, the large external tank will be used to store cold water. In this case, the cooling water does not go directly from the cooler application, but goes deep into the outside of the tank as a "temperature buffer sorting behavior. The cold water tank is much larger than the internal water tank. Cold water from the external fuel tank application And returning hot water from the application can be traced back to the external fuel tank, not to the unit.

Less common open-loop controlled industrial chillers in an open tank or oil sump it continuously circulates the temperature of the liquid. The liquid is coming from the tank, through the pump unit, back to the tank. An adjustable thermostat sensory makeup liquid temperature, circulating a cooler to keep the tank constant.

One of the new developments in industrial chillers is air cooling, not the use of cooling water. In this case, the condenser is not cooled with hot air refrigerant, but is used by a cooling water cooling tower. This development allows for more than 15% and allows for a reduction in energy demand in the cooler due to the small area of surface water, in the case of condensers and fans. In addition, the fans allow for a significant reduction in noise levels.

Most industrial chillers cool media cooling, but some simple techniques that rely on air or water include a cooling coil that regulates temperature. Water is the most commonly used coolant in the freezing process, although cooling mixtures (mainly with coolant additives to enhance heat sinking) are often used.
