Submit RequirementsFAQ About 3HP Compact Air-Cooled Industrial Chillers
What is a 3HP air-cooled chiller?
A 3HP air-cooled chiller is a compact industrial water chiller that uses an air-cooled condenser to remove heat from process water. It is commonly used for small equipment, laboratory systems, laser machines, water tanks and general process cooling.
How much cooling capacity does a 3HP chiller provide?
A typical 3HP air-cooled chiller provides approximately 8-9 kW of cooling capacity, depending on chilled water temperature, ambient temperature, compressor selection, condenser size and pump configuration.
Does this chiller need a cooling tower?
No. This is an air-cooled chiller, so it rejects heat through the air-cooled condenser and does not require a cooling tower or cooling water system.
What applications are suitable for a 3HP compact chiller?
It can be used for small laser equipment, laboratory instruments, reaction baths, small molds, auxiliary CNC cooling, water tanks, fish tanks and other small process cooling applications.
Can the water tank and pump be customized?
Yes. APT can customize water tank volume, pump flow rate, pump head and water circuit configuration according to the customer's process requirement.
Can this 3HP chiller be used for laser cooling?
Yes. It can be configured as a laser cooling chiller for small laser machines when the required cooling capacity, water flow and temperature accuracy match the equipment requirement.
Can this chiller be used for laboratory cooling?
Yes. It is suitable for laboratory cooling water circulation, test loops, reaction baths and instruments that require stable chilled water in a compact installation space.
What clearance is required for the condenser and top fan?
The side ventilation panels should have enough air intake space, and the top fan outlet should remain open so hot air can discharge smoothly. Final clearance should be confirmed according to installation conditions.
Can APT supply 220V, 380V or 415V versions?
Yes. Voltage and frequency can be customized according to the destination country, including 220V, 380V, 415V, 50Hz or 60Hz configurations.
How do I know whether 3HP is enough for my process?
The correct chiller capacity should be selected based on heat load, required water temperature, water flow, ambient temperature, working time and insulation conditions. APT can help review these parameters and recommend a suitable model.
Can the evaporator material be customized?
Yes. Water contact materials and evaporator structure can be selected according to water quality and application requirements, including stainless steel options when corrosion resistance is needed.
Is this chiller suitable for high ambient temperature?
Standard air-cooled chillers should be checked carefully for high ambient conditions. For hot climates or outdoor installation, APT can customize condenser size, fan airflow and compressor selection.
