Industrial Chillers – Working, Types and Applications

Industrial Chillers

An industrial chiller is a type of machine which removes heat via absorption refrigeration cycle or vapor-compression. It involves the process of installing various condensers, piping, pumps and other components to create an industrial cooling system. This industrial refrigeration equipment utilizes either absorption or water vapor to eliminate the heat out of liquids such as glycol, lithium bromide solution, water, inhibitors or other fluid. In order to cool the liquid, the system uses water, air or evaporation.

 

Chillers for various industrial applications can be centralized or decentralized. Each system has its benefits. Centralized chillers typically have capacities from ten tons to thousands of tons. Decentralized chillers are commonly small in size and have cooling capacity from 0.2 to 10 tons.

 

Most of industrial chillers circulate approximately four hundred tons of water, in large industrious facilities. A chiller of this type tends to be rather bulky and large, thus, they are located on rooftops and on the sides of buildings. These are commonly used when commercial and industrial buildings need to switch from city water as they are growing and expanding enough to justify it. Sometimes, these are utilized as a substitute of evaporative cooling towers, since cooling towers enable refrigerant chemicals to come into contact with cooled water while in chillers; the refrigerants are kept within a closed circuit.

 

Closed-loop industrial chillers circulate a clean water or clean coolant with condition additives at constant pressure and temperature to increase the reproducibility and stability of water-cooled instruments and machines. The water runs from the closed-loop industrial chiller to the application’s point of use. The less known open loop industrial chillers have the capability to control the temperature of liquid in an open sump or tank by consistently circulating it. The liquid flows from the tank, runs through the chiller and back.

 

Industrial water chillers use water cooling rather than air cooling. With this type of chiller, the condenser does not use ambient air to cool the hot refrigerant, but utilizes water which is cooled by a cooling tower. This process enables a reduction in energy consumption by at least 15% and also permits a reasonable reduction on the chiller size, due to the absence of fans and the small space occupied by the water-based condenser. In addition, there is significant reduction of noise levels because of the absence of fans.

 

Applications of Industrial Chillers
• Chillers are employed to cool hot plastics that are blown extruded, injected or stamped in the plastic industry.
• In the printing industry, industrial chillers are utilized to remove the heat created by printing rollers. These also help to cool down the equipment employed in manufacturing process.
• Industrial chillers help cool down the source of power supply and the laser equipment.
• Top standard chillers are utilized extensively in the high powered electronics within the machines such as PET and MRI, employed in newly innovated diagnostic tools.
• These are used for controlled cooling products, factory machinery and mechanisms in a broad array of industries.
• Industrial chillers are employed in machine tooling and die-casting, pharmaceutical formulation, chemical processing, vacuum systems, food and beverage processing, welding equipment, metal working cutting oils, X-ray diffraction, analytical equipment, power generation stations, semiconductors, cement processing as well as compressed air and gas cooling.
• These are also installed in hotels, campuses and hospitals.
• Water-cooled chillers are often intended for indoor operations and installations while air-cooled chillers are designed for outdoor operations.
