(Parallel Compressor Systems (Rack

Multi compressors – rack system – are assembled in a structure of metal base, by coupling two or four parallel compressors so that compressors are positioned in the top and all other equipment is positioned undernea
Oil reservoirs provide a holding charge of oil in an oil control system.the amount of oil circulating in a refrigerating system varies depending on the operating conditions.the oil reservoir caters for these fluctuations by providing additional storage capacity .the oil reservoir is fed by the oil separator and feeds the oil level regulators, mounted on the compressors crankcases . oil reservoir is supplied with two rotalock valves to easy connect oil fill and oil drain. a connection on the top permits the assembling of a pressure vent valve
The reservoir is provided of two sight glasses to check the oil level
The oil reservoirs are suitable for HFC refrigerant fluids,particularly R134a, R404A, R407C, R507 mixed with polyester lubricants . they are also suitable for old CFC or HCFC refrigerant fluids, mixed with mineral lubricants
Condensers can be air cooled, evaporative and shell & tube water cooled that connects rack to cooling tower
Rack system consist of
Oil level regulator
Connection adapter
Discharge line
Oil separator
Check valve
Oil reservoir container
