Industrial Coaxial Bearing Oil Coolers For Screw And Centrifugal Air Compressors

Air compressors operate under high rotational speeds and continuous thermal load, making bearing lubrication oil cooling essential for reliable performance. To ensure stable temperatures and protect the bearing system, coaxial (tube-in-tube) oil coolers and spiral oil coolers are widely used due to their compact design, high heat-transfer efficiency, and resistance to fouling.

Key Features of Our Coaxial / Spiral Bearing Oil Coolers

• Compact and Space-Saving Design

Ideal for compressors with limited installation space, skid-mounted units, or retrofits.

• High Thermal Efficiency

Counter-flow or spiral flow paths achieve rapid oil temperature reduction with low coolant consumption.

• Durable Construction

Available materials include:

Copper

Copper–nickel (CuNi 90/10 or 70/30)

Stainless steel (304/316L)

Designed to resist wear, corrosion, and vibration.

• Low Pressure Drop

Smooth oil channels maintain proper lubrication flow to bearings, even under high viscosity conditions.

• Easy Maintenance

Simple construction allows easy inspection, flushing, and cleaning.

• Fully Customizable According to Compressor Brand

Dimensions, tube diameter, connection size, and heat duty can be manufactured according to:

OEM specifications
