1. Selection by Air Compressor Discharge Volume and Target Temperature
Selection depends on air compressor discharge volume, inlet temperature, target outlet temperature, and ambient temperature. SCA-03 (8.5 kW) is used for small piston air compressors. SCW-8 (21.5 kW) and above are used for screw air compressor after-cooling. Provide air compressor nameplate parameters for selection.
2. Evaporator Options for Compressed Air Pipeline Pressure
Compressed air side heat exchanger options include shell-and-tube or stainless steel plate. System pressure hold is 26 bar, suitable for standard air compressor discharge pressure range. For compressed air with high oil content, shell-and-tube evaporator allows periodic cleaning.
3. Water-Cooled and Air-Cooled Options
Workshops with cooling water can use SCW water-cooled series. Cooling efficiency is less affected by ambient temperature. Workshops without cooling water can use SCA air-cooled series. Installation is simpler. Air-cooled series requires sufficient space on air inlet and outlet sides.

Actual selection must consider air compressor discharge temperature, target outlet temperature, ambient temperature, and compressed air oil content. Provide air compressor nameplate parameters for technical calculation.
- Evaporator type: shell-and-tube, stainless steel plate
- Condenser type: shell-and-tube, tube-in-tube (water-cooled) or finned (air-cooled)
- Refrigerant type: R22, R407C
- Power supply: 380V/3/50Hz
- Connection size and port direction
- Brand logo and nameplate
- Export packaging marking and manual language
products are 100% inspected before shipment. Inspection focuses on compressed air side heat exchanger air-tightness, pressure held at 26 bar.
Each unit is vacuum leak tested before refrigerant charging. After charging, cooling capacity is verified on the cooling capacity test bench. Shell-and-tube heat exchangers are individually water pressure tested before assembly to confirm no cross-leakage between compressed air and water circuits.
Q: What parameters are needed to select a compressed air chiller?
A: Provide air compressor discharge volume (m³/min), discharge temperature, target outlet temperature, ambient temperature, compressed air oil content, and site power supply. If cooling water is available, provide cooling water inlet temperature and flow. After providing these parameters, technical personnel can calculate and recommend a model.
Q: Can the product connect directly to existing air compressor piping?
A: Yes. The unit has compressed air inlet and outlet connections. Connection size is confirmed by model. If existing piping connection size does not match, discuss a transition solution at order confirmation. An oil-water separator is recommended between the air compressor and the chiller to reduce oil entering the heat exchanger.
