Oil reservoirs are storage tanks that receive oil from oil separator and provide its return to the compressor’s crankcase through oil level regulator. Amount of oil circulating in a system varies depending on operating conditions. Oil reservoir prevents compressor’s crankcase from staying without oil during potential fluctuations by providing additional storage capacity. Oil reservoir prevents liquid refrigerant from flowing to the oil level regulators and therefore fluctuations in the oil level caused by compressors are prevented. Recommended to be used in following systems: Flooded systems with large refrigerant charge, two or more compressors operating in parallel, long suction and discharge lines, double suction line risers. Oil reservoir should be installed between oil separator and oil level regulator. Select an oil reservoir according to the number of compressors connected, compressor oil charge, system refrigerant charge, operating conditions and oil volume of the unit.
