Description;
Oil reservoir (oil receiver) preserves the oil isolated by the oil separator and feeds it back to the compressor carter via oil level regulator.
Oil reservoir prevents liquid backlash to the oil level regulators, thereby immediately eliminating the fluctuations in liquid flow caused by the compressors.

Functional Specification ;
Oil reservoirs should be installed higher than the compressor carter, and selected in accordance with the number of the compressors and the oil capacity of the unit.

Note ;
Oil should be added in case the oil rate is below the sight glass level on the oil reservoir.
Oil reservoirs are produced in accordance with the 97/23/EC directive.
