Oil Pot Controller - Oil Return

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.

Key features

Liquid temperature range: Operate across a temperature range of -60°C to 80°C (-76°F to 176°F).
Pressure tolerance: Rated for pressures up to 150 bar (2175 psi).
Power supply: The switch operates on a 24 V AC/DC power supply.
Split design: Simplifies installation and diagnostics; electronic parts can be removed with two screws.
LED indicators: Offers clear visual indicators for oil level, alarms, and power supply, with an alarm output to a central panel.
Easy configuration: Configuration with a PC using HB Tool software.
