A
Popular Alternative
A water chiller is an industrial water
refrigeration apparatus that produces cold water to cool
industrial process equipment. A water chiller is a complete
system filled with refrigeration components, including a
condenser, refrigerant, pipes, coolant expansion reservoir,
pumps, and so on. Water is cooled to temperatures around
20°C (68°F) and pumped through a water or glycol circuit to
reach the process equipment.
Water chillers are a popular alternative for industrial
facilities growing fast enough that the move from city water
to specialized chilling units becomes cost-effective. Water
chillers are also a well-known alternative to evaporative
cooling towers. They are often claimed to be superior to
towers in that the coolant water comes into contact with air
in a tower, but stays in a closed circuit in a water chiller
system.
Selecting a water chiller requires calculating the exact
amount of chilling needed, that is, the precise amount of
energy added to the coolant by the process machinery. Then a
water chiller may be selected for maximum efficiency.
Water chillers conserve water by cycling the coolant in a
closed circuit, rather than continuously pumping in city
water. Adequate cooling is especially necessary in precision
manufacturing, where slight overheating can cause thousands
of dollars in lost product or equipment. Some specialized
chillers can lower the temperature of non-water coolants to
as low as -50°C (-58°F). Process equipment that requires
cooling includes lasers, ozone generators, plastic
applications, vacuum pumps, cutting and welding machines,
packing and printing machines, X-ray machines, STM
microscopes, and plenty more.
