Container Type Compressed Air System with Screw Compressor and Air Treatment Equipment

A containerized air purification station is a complete compressed-air generation and treatment system installed inside a container. It can include an air compressor, oil-water separator, refrigerated dryer, adsorption dryer, filters, receiver tank, control system, ventilation, and optional low-dew-point or oil-removal modules.

Its purpose is to deliver stable, clean, dry compressed air for industrial processes or as feed air for oxygen and nitrogen generation systems. Proper purification removes water, oil, dust, and other contaminants that can damage equipment or affect product quality.

A typical station includes a screw compressor, aftercooler, gas-liquid separator, refrigerated dryer, desiccant dryer when needed, precision filters, activated carbon filter if oil vapor control is required, air receiver, drains, PLC control, ventilation, and electrical distribution.

Compression increases air temperature and concentrates water vapor. As air cools, condensate forms and can cause corrosion, valve malfunction, microbial growth, product defects, and downstream equipment failure. Dryers reduce pressure dew point to a safe level.

A refrigerated dryer is suitable for general industrial compressed air where a moderate pressure dew point is acceptable. It is energy-efficient and commonly used before filters or as a first-stage dryer before a desiccant dryer.
