Oil Ejector

Technical data: HBEJ-MK2

HBEJ-MK2 is an oil ejector for automatic oil drainage for industrial ammonia refrigeration systems. The ejector is used together with an HBOR oil pot controller and 2 magnetic valves. The ejector uses hot gas as propellant and is designed for a hot gas pressure of max 120 bar. The ejector is made in stainless steel and has compression fittings as well as a thread connection.
The ejector is a simple economical solution for transporting oil from point A to point B without worn parts and with a low energy consumption.

HBEJ oil return ejector could be used on CO2 system to return the collected oil / refrigerant mixture from the evaporator to the suction line on flooded systems.

The ejector will empty 0,05 l/minute minimum.
