5–20 HP Industrial Air-Cooled Chillers
APT 5–20 HP industrial air-cooled chillers are designed for medium-capacity process cooling applications such as injection molding, laser equipment, electroplating, CNC machines, thermal spray auxiliary cooling, factory equipment, and industrial water cooling systems where cooling tower installation is not preferred.
When Should You Choose a 5–20 HP Industrial Air-Cooled Chiller?
A 5–20 HP industrial air-cooled chiller is suitable when a production machine, laser system, injection molding process, electroplating bath, CNC machine, thermal spray auxiliary loop, or factory equipment needs stable medium-capacity chilled-water cooling without a cooling tower. It is usually a better choice than a 1–5 HP compact chiller when the heat load, operating hours, pump flow, tank volume, or industrial duty cycle is higher.

What is a 5–20 HP industrial air-cooled chiller used for?
It is used for medium-capacity process cooling applications such as injection molding, laser equipment, electroplating, CNC machines, thermal spray auxiliary cooling, process tanks, factory equipment, and industrial water cooling systems.
How do I choose between 5 HP, 10 HP, 15 HP, and 20 HP?
Selection depends on heat load, target outlet temperature, process water flow, pump pressure, tank volume, ambient temperature, operating hours, and required cooling margin.
When should I choose a 5–20 HP chiller instead of a 1–5 HP compact chiller?
A 5–20 HP air-cooled chiller is recommended when the heat load, duty cycle, flow rate, tank volume, or industrial operation requirement exceeds the practical range of compact chillers.
Can this series be used for injection molding cooling?
Yes. 5–20 HP air-cooled chillers are commonly used for small and medium injection molding machines, mold cooling, hydraulic oil cooling, and auxiliary process cooling when the heat load is suitable.
Can this series be used for electroplating or chemical process cooling?
Yes, but electroplating or chemical process cooling requires water quality, corrosion risk, heat exchanger material, pump, tank, and secondary loop review before final selection.
Does a 5–20 HP air-cooled chiller need a cooling tower?
No. An air-cooled chiller rejects heat to ambient air through the condenser and fans, so it does not require a cooling tower. Proper ventilation and service clearance are still required.
What pump flow and pressure should be confirmed?
Pump flow and pressure should be reviewed according to equipment heat exchanger resistance, pipe distance, height difference, filters, tank size, and process circulation requirements.
Can APT customize voltage, pump, tank, and controls?
Yes. APT can customize voltage, frequency, pump flow, pump pressure, water tank, control panel, alarm output, cabinet layout, and other project-specific configurations.
When should I consider a water-cooled chiller instead?
A water-cooled chiller may be considered when the project has larger heat load, stable cooling tower or condenser water, indoor heat rejection limits, or continuous-duty efficiency requirements.
What information is needed for a 5–20 HP air-cooled chiller quotation?
Please provide application, heat load or equipment power, target temperature, flow rate, pump pressure, coolant type, voltage, ambient temperature, installation space, operating schedule, and any customization requirements.
Need a 5–20 HP Air-Cooled Chiller Recommendation?
Share your application, heat load, target temperature, process flow, pump pressure, coolant type, voltage, ambient temperature, and installation conditions. APT engineers can review your medium-capacity process cooling project and recommend a suitable 5 HP, 10 HP, 15 HP, or 20 HP air-cooled industrial chiller configuration.
