In the heat treatment and coatings industries, a range of cooling and chiller devices are used. It is common in vacuum heat treating to use the cooling performance of a chiller to provide cooling to diffusion pumps, as well as heat exchangers on the gas quench operation.
In the plastics industry, chillers can
be used for a variety of purposes. Some are used for cooling the hot plastic
that is injected, blown extruded or stamped and others are used to ensure
productivity levels by cooling down the equipment in the manufacturing process.
Chillers are also used in the printing industry to
remove the heat generated by the printing rollers and also cool down the paper
after it comes out of the ink-drying ovens.
On machine tools, the spindle and
cutting fluid can be cooled by chillers. In EDM processes, chillers cool the
machinery. Lasers and their associated power supplies are cooled by chillers,
and high powered electronics (used in MRI scanners) also take advantage of
chillers to remove unwanted heat.
