OIL SEPARATOR
In the installation of air cooled units (AX-AD) with remote condenser, if the refrigerant pipeline are more than 50mt is recommended to
install an oil separator on site, in order to avoid that the oil goes away with the refrigerant causing compressor damages
Finally, the use of an oil separator leads to:
• a longer life of the compressor;
• a better performance of the whole system with consequent energy saving, due the high coefficient of condenser and evaporator perfor-
mance by almost completely removing oil deposits from their exchange surfaces;
• a quieter operation by reducing pulsations.
The oil separator have to be selected considering the following parameters:
• power cooling of refrigerant system
• refrigerant fluid type
• the inlet diameter of oil separator have to be equal to the dicharge gas diameter of compressor

* refered to evaporating temperature +5°C and condensing temperature 40°C
The oil separators have to be installed in the discharge line between the compressor and the condenser mounted securely in a vertical
position and reasonably close to the compressor.
Oil separator performs best when operating at or near the compressor discharge temperature. In location the oil separator, choose a posi-
tion to avoid, as far as possible, chilling of the shell, which may result in condensing of liquid within the separator. If this is not possible, it is
advisable to supply the separator with the insulation or strap heater to prevent the refrigerant in the system from condensing in the shell.
Acting as the lay out of refrigerating system, the return line may be run from the oil fitting to the suction line upstream the compressor.
A sight glass may be installed in the oil line, in a position that oil is flowing through the tube, to check the correct working of the oil separa-
tor. Oil separators must be always pre-charged before its use, as described on the table, with the same oil of the compressor.
