Selecting the correct water chiller is one of the most critical decisions in a plastic manufacturing facility. An undersized chiller will struggle to maintain temperature, leading to defective products. An oversized unit means wasted energy and higher operating costs.
Heat Load (kcal/h) = Material Weight (kg/h) x Specific Heat (kcal/kgC) x Temperature Difference (C)
For most plastics, specific heat ranges from 0.3 to 0.55 kcal/kgC. Always add a 20-30% safety margin.
Cooling water flow rate for medium-sized injection molding typically ranges from 50 to 200 L/min.
Air-cooled chillers: ideal for small-medium operations, easier to install.
Water-cooled chillers: higher efficiency, better for large-scale facilities.
PID controllers maintaining +/- 0.1-1C ensure consistent quality in precision molding.
