Technical data: HBOR
HBOR is a liquid level switch designed for automatic Oil return in ammonia systems. The sensor measures and detects the difference between the refrigerant and oil in a refrigeration system. Increased security is achieved as the sensor measures when the oil is drained and ammonia surrounds the sensor, the Oil Pot Switch closes the drain valve, without the risk of ammonia being emitted to the surroundings. Used for oil return / discharge of separated oil in e.g. evaporators, receivers and oil pots.
HBOR is mainly used for the low pressure side of the refrigeration system.
