Obviously chiller is a cooling system that removes heat from one element and transfers it into another.  It decrease  the temperature of the equipment and to protect them. Meanwhile it also increase the production when you provide contant temperatute to in your processing equipment.

Equipment Protection
The most compelling reason for a chiller is the protection it provides your valuable processing equipment: such as spot welders, injection molding equipment and other applications. A chiller commonly represents a small fraction of the cost of the processing equipment, yet it provides solid protection of your investment, 24-hours-a-day, 7-days-a-week for years and years to come.

Increase Production
The speed and accuracy of production will increase as you maintain a constant and proper cooling temperature in the equipment. A chiller will reduce the number of rejected parts while increasing the number of parts produced per hour.
