Oil Reservoir Type ORV

Model Series

APPLICATIONS
This Oil Reservoir are used in Low and High Pressure Oil Control Systems. Due to system design, loading and defrosting cycle, the changing oil mass can be send back by oil separator, thus, a safety oil reserve is required for the operation of oil control system. In the oil reservoir, any refrigerant trapped within the oil is boiled - off and the oil is cooled and kept available. WELCOLD oil receivers are normally equipped with sight glasses with float ball level indicators, for upper and lower level indication, and with 2 shut off valves, the top valve receives valve from oil separator, and the bottom valve sends oil to the oil regulator.

CONSTRUCTIONS

• 2 or 3 sight glassses with level indicator balls
• check the oil level in the receiver
• 2 rotalock valves to easy connect oil fill and oil drain. These valves are not mounted on the receiver; they are in the package with the proper gaskets.
• a 3/8" SAE Flare connection on top of the receiver can allow to assemble a pressure differential check valve. Note: The pressure differential check valve is not supplied with receiver; if it's necessary to use a positive differential pressure between the receiver and the compressor crankcase, we recommend WELCOLD Pressure differential check valve.
• OPV-2003 (with differential pressure of 1.38 bar)
