Oil Air Cooler (Turbine and Compressor Oil Cooler)
The oil air cooler is designed for cooling low-pressure oil and lubricating oil used in gas turbine engines and compressors at gas compressor stations. It is intended for outdoor operation.
The unit is supplied as a single block in full factory-ready condition and does not require on-site assembly.
The cooler consists of one heat exchanger section with end chambers, cooled by an airstream generated by axial fans. The section is installed horizontally and mounted on a metal supporting frame together with axial fans, drives, louvers, diffusers, and ducting.
