Oil Management Control Switch

Technical data: HBOC/C

HBOC/C is an intelligent sensor with a built-in microprocessor. It is designed to detect and control oil levels in oil separators and compressors. Apart from the sensor function, it also has a built-in controller.

The controller can be setup with all the parameters that are necessary to directly regulate a solenoid valve for oil level control.

HBOC/C is mainly used for the high pressure side of the refrigeration system.
