An industrial water chiller is an appliance which eliminates heat from a fluid through a gas-compression or absorption cooling process. This fluid can then be distributed via a heat exchanger to cool gas or equipment. As a byproduct, refrigeration generates surplus heat which must be released to ambient or, for greater efficiency, recuparated for heating necessities.

The optimisation of production processes is an absolute priority in modern industry. The utilisation of chilled water is a significant aid in this optimisation process.

The use of a closed cooling circuit, where water is alternately heated by the process and chilled by a cooling system, is the best way to prevent waste of valuable water and the problems related to the drainage of impure water.

Closed circuit water cooling systems can essentially be divided into two main categories: the first category utilizes a refrigeration circuit (i.e. process water chillers), while the second uses ambient air to cool the water; a dry fluid cooler is undoubtedly the most common example of this second category.

Chilled fluid is needed to cool and dehumidify air in medium to huge commercial, industrial, and institutional (CII) facilities. Industrial water chillers can also be cooled by water, air or sometimes cooled via evaporation. Chillers cooled by water integrate use of cooling towers that advance the chillers’ thermodynamic efficiency as compared to chillers cooled by air. This is because of heat elimination at or close to the air’s wet-bulb temperature. Chillers cooled by evaporation offer greater efficiencies than chillers cooled by air but lower than chillers cooled by water.

As one can imagine industrial water chillers are extremely important in the industrial world where there are literally millions of machines that generate a lot of heat. If these machines are to last any time at all, they should be cooled. This is where chillers come in. A chiller may sometimes be used to cool any machine or process that operates at 60 degrees F or lower. A cooling tower may also be needed to cool any machine or process that operates at 85 degrees F or higher. Some of the more common applications are listed below:

Plastics

Within the plastics industry, a refrigeration process cools the hot plastic that is added, blustered, extruded or stamped. A cooling process can also reduce the temperature of the equipment that is important in creating plastic products that conserve on energy and on the wear and tear of the machine.

Laser

In industries that use laser cutting, light projection industry, etc. a chilling system is necessary for cooling down the lasers and power supplies.

Rubber

In the rubber industry to cool the multizone water temperature control units of the rubber extruder barrel, cool the rubber mill, calendars and bambury mixers.

Beverage

In the beverage industry, a chiller removes the heat gained from the process during mixing, cooking, or after pasteurizing the product.

Medical

In case high technology equipment is used for magnetic resonance imaging, scanning, cooling of blood and laboratory testing, a cooling system is needed to remove the heat generated
