Oil Pot Controller

Technical data: HBOR/C

HBOR/C is a level sensor with a built-in controller for controlling the oil return from the oil collection points in industrial cooling systems. The sensor is installed in the oil pot at the level where automatic emptying should take place. When the sensor no longer detects NH3, it automatically opens the solenoid valves so that hot gas is fed over an ejector. The ejector forms a vacuum so that the oil pot is automatically emptied. The oil emptying function is set with a PC tool.
