OCS Receivers

Cooling and Conditioning Components

Established in 1972 by Giancarlo Maggiolo, later on supported by his son Maurizio and his daughter Martina, OCS has become an important reality in the italian and international panorama of refrigeration and cooling components.

With its thirty years’s experience , OCS is a family owned  company which the first porpose is to supply custumers with a very high standard of quality. Thanks to its qualified staff and a versatile customer oriented
production , OCS currently offers a vast range of products, all of which carry TUV and ISO 9001 certification. 

Liquid Receivers

There are two different type of liquid receivers: VERTICAL or HORIZONTAL. The selection of the liquid receiver must consider the volume of the condenser coil and and the refrigerant load. The liquid receiver must be mounted after the condenser coil in order to ensure the compensation of refrigerant volume variations. OCS supply liquid receivers perfectly clean, dried and with hermetic closing. All OCS’s liquid receivers are supplied with ODS or ROTALOCK connection as well as safety valve connection.

Suction Accumulators

Suction accumulators must be mounted in vertical position and if it is possibile at the same height of compressor and as close as possibile to it.
Mounting of suction accumulators must follow the IN/OUT direction applied on the connection. The selection of suction accumulator must consider that the capacity of the refrigerant liquid must be at least within 50% of the total amount of the plant. In order to prevent suction accumulator it is recommended to heat insulate it. In order to guarantee a suitable oil return to the compressor, the refrigerant flow speed should be between 8 and 12 m/sec. For lower speed it is not guaranteed a suitable oil return. On request OCS can produce suction accumulators up to 600 LT capacity.

Oil Receivers / Separators

Oil Receivers must be mounted between oil separators and oil level regulators connected to the compressor case. The oil receiver allow a regular oil flow to the compressor. All oil receivers are suppliedwith sight glasses to visualize the oil level. The oil receiversmust bemounted always in vertical position.

Oil separators allow a regular oil return to the compressor. Oil separators must be mounted in vertical positioning the discharge line as close as possible to the compressor. Mounting oil separators must follow the IN/OUT direction applied on the connection. The selection of oil separators must consider the following condition:

  • type of refrigerant used
  • evaporation temperature
  • power compressor

Mufflers

Mufflers must be mounted on the discharge gas line next to the compressor in order to reduce the noise caused by gas pulses. Mufflers can  be mounted in horizontal or in vertical position. The selection of muffler must consider the diameter of the discharge compressor’s pipe. OCS recommend to install a proper clamp before the intake and after the outlet of the muffler

Manifolds

Manifolds are applied in a multi compressor system in order to distribute suction gas in homogeneous way permitting the oil recovery.
Manifolds are made with one pipe-in connection but they can have several pipe-out connection it depends on the number of compressor. In order to preventmanifolds it is recommended to heat insulate them. For more details about manifolds manufacturing please contact OCS’s  technical dept. On request OCS can producemanifolds up to 600 LT capacity.
