Mechanical oil level float

Proper oil management is essential to ensure compressor lubrication. .

Control and maintain the oil level inside the compressor crankcase, which protects the compressor from damage such as wear on the compressor pistons and excess oil in the cooling or air conditioning system, which reduces the efficiency of the system by:

• Reduction in heat transfer due to oil coating of the condenser and evaporator walls.
• Oil does not change state from liquid to gas and is not a coolant.
• A minimal amount of oil flowing through the system is necessary to provide lubrication for the valves.

Suitable for use with HCFC and HFC refrigerants and compatible oils.

The SN model is unique in its ability to be used with ammonia, R410A, and subcritical CO2.

Technical data:

• Maximum working pressure 31 Barg
• In the SN model, maximum working pressure is 40 Barg.
• Operating temperature 0°C to +130°C
• In the SN model, the operating temperature is 10°C to +110°C.

In systems that use parallel compressors, a low-pressure oil management system is used. This system has three main components: an oil separator, an oil reservoir, and oil floats. The system is designed to allow joint discharge from the compressors to the oil separator, thereby increasing the efficiency of oil separation before it passes to the condenser.

A critical addition to this system is the use of pressure valves to maintain constant pressure in the oil reservoir, which improves the oil return process. Oil floats play a vital role in maintaining the proper oil level in each compressor, opening to feed oil when levels drop and closing when levels are sufficient.
