Sizing an industrial chiller is not about matching the chiller brand to your injection machine or simply picking the biggest unit you can afford. The correct chiller size is driven by the heat you need to remove per hour, then cross-checked against your machine clamp tonnage, material, cycle time, ambient temperature, and the water flow rate your mold requires. As a quick reference, 1 HP of chiller capacity is roughly 3,000 kcal/h, 12,000 BTU/h, or 3.5 kW of cooling, and a common rule of thumb for standard commodity plastics is about 1 HP per 80–100 tons of clamp force, rounded up for engineering resins, fast cycles, and hot climates. Undersizing is the single most common and expensive mistake buyers make.

In laser and injection molding industries, even a ±1°C water temperature fluctuation can cause defective products or equipment damage.This article explains how air cooled chiller and water cooled chiller solutions from LESINTOR — a professional chiller manufacturer — ensure stable production.We are an original factory, now recruiting global agents and distributors.
