Ecochillers in the
Plastics Industry
Ecochillers® have proven experience in the plastics industry, which guarantees the most efficient designs. Our chillers are installed to cool injected, extruded or blown plastic. The equipment used to create a plastic mold may also require cooling allowing the machine to run more efficiently.
This will help the machine run more efficiently and contribute to a longer machine life.
Please contact us if you need help selecting a chiller for your plastic cooling, mold cooling, injection molding coolers, process cooling equipment, plastic injection molding, etc. needs.
What is a plastic cooler?
A plastics chiller is a refrigerated unit that cools water to cool plastics molding, extrusion, blow molding throughout the manufacturing process. A closed loop system is recommended, so plastic waste cannot mix with the process water.
Capacity calculation
Chiller for plastic injection
The selection of the chiller is obtained based on the following tables, the ideal selection is based on the closing capacity of the machine Table 1, tables 2 and 3 are complementary based on the kilograms of product or the hp of the injector.
Based on Table 1, if it handles 3 injectors of 150 to 200 tons, the recommended chiller would be 15 tons if only the Mold is cooled, if it is desired to cool the Mold and the Oil 20 tons.
Tables for calculation and selection of Chillers on injection molding machines
Chiller calculation for plastic injection molding based on machine injection tons or clamping force.
Example: 3,024 K Cal = 1 ton of cooling.
Cooling mold and oil
1 150 ton machine: 16,000
2 200 ton machines : 40,000
Total k cal/hr: 56,000
In tons = 56,000 / 3024
Chiller capacity = 18.51
