Technical data: HBOR

The HBOR is a Level Switch designed for automatic oil return in ammonia refrigeration systems. This sensor detects the difference between refrigerant and oil, ensuring that when oil is drained and ammonia surrounds the sensor, the drain valve closes without risking ammonia leaks. It is typically used for oil return and discharge in components such as evaporators, receivers, and oil pots, primarily on the low-pressure side of the system.

Technical data: HBOR/C

The HBOR/C is a sensor designed to detect oil in liquid ammonia, similar to the HBSR switch, but with enhanced capabilities. It can directly control a valve to fill or empty a container, helping maintain the correct oil level in ammonia refrigeration systems.
