Cooling Challenges in High-Capacity Industrial Applications

Large industrial equipment and production lines generate higher and more continuous heat loads. APT designs 20-50 HP large air-cooled chillers to support stable process cooling, reliable operation, and practical installation in demanding industrial environments.

High Heat Load

Large injection molding machines, extrusion lines, die casting systems, and thermal spray equipment can generate continuous high heat. A large air-cooled chiller helps remove process heat and maintain stable water temperature.

Multi-Point Cooling Demand

Large production systems may require cooling for multiple molds, tanks, hydraulic stations, heat exchangers, or process loops. APT can configure flow rate, pump pressure, tank volume, and piping connections based on system layout.

Continuous Operation Stability

High-capacity industrial chillers often run for long shifts or 24/7 production. Reliable compressors, condenser airflow, pump protection, and safety controls are essential for stable cooling performance.

Installation & Ventilation Requirements

Large air-cooled chillers require proper ventilation, maintenance clearance, electrical configuration, and site planning. APT supports custom layout, voltage, control, and installation requirements for industrial facilities.
