Oil Separator 1.1/8″ ODS OS540/9 Castel

The Castel OS540/9 oil separator is used in refrigeration and HVAC systems to remove oil carried by discharge gas from the compressor. By separating the oil and directing it back to the compressor crankcase, it ensures proper lubrication and stable system performance.

In larger systems, oil can circulate through the piping network and reduce heat transfer efficiency. An oil separator minimizes this issue, protecting the compressor and maintaining cooling capacity.

Built for professional applications, this model with 1.1/8″ ODS connection is suitable for commercial and industrial refrigeration installations.
