Oil Separator Type

APPLICATIONS
Both the oil separators OSN & OSC are designed for installation on commercial refrigerating systems and on civil and industrial conditioning plants can protect systems. When the compressor is running, the outlet of compressor always has lots of refrigerant oil. If too much oil moves to the system, it will affect the flow control components and the performance of evaporator and condenser.

The oil separator installed on the discharge line of the compressor intercepts the oil mixed with compressed gas and returns it to the oil receiver or directly to the compressor crankcase thus assuring an efficient lubrication of its moving parts. Furthermore, the oil separator maintains a high coefficient of condenser and evaporator performance by almost completely removing oil deposits from their exchange surfaces. Moreover, the oil separator, damping the valves pulsations, reduces system noise with an open or semi-hermetic compressor.

The use of an oil separator leads to;

- A longer service life of the compressor
- A better performance of the whole system with consequent energy saving
- A much quieter operation by reducing pulsations

TECHNICAL DATA

• Design working pressure : 4.8 MPa (48 bar)
• Working with temperature : -10℃ ~ +120℃
• For use with HFC & HCFC Refrigerants (R134a, R404A, R507A, R407C, R22 etc). To cover the demand for components with an increased working pressure for R410a and as well for subcrtical for CO2 applications.

CONSTRUCTION

WELCOLD supply 2 types of oil separators : Closed Type and Demountable Type.

• Separators series OSC are hermitac type and they cannot be dismantled from the system, except cutting the piping.
• Separators series OSN are demountable type.

The internal device is simple in order to assure a trouble-free long operation. Appropriate metallic screens, placed on the inlet and outlet, rapidly reduce gas speed, and create the conditions required for the separation of the oil from the refrigerant. A float operated needle valve, set on the bottom of the vessel, returns the oil to the crankcase of compressor.
