Oil level controllers

Maintaining oil level at required levels in compressors like reciprocating and scroll compressors is an important task to be performed in order to avoid damage to the compressor crankshaft, gears etc. Mal functioning of compressor can lead to shutdown of the entire refrigeration system. The oil helps in lubrication and dissipation of frictional heat from the contacting members and increases compressor life.

In rack compressor arrangements, the oil level can be maintained passively through oil equilibrium lines. But these systems function properly only under constant operating conditions.

 

The oil level is maintained at desired levels by specially designed control systems. Modern oil level controllers use electronic circuits to achieve the objective. A typical electronic oil level controller that performs both functions of oil level monitoring and oil level balancing is described below.

The system is compatible with most refrigerants like HFC, HCFC, and CO2.

The mounting onto the compressor is simplified by the dual pitch flange design. In case of different compressors fittings some adapters are available to allow a quick and easy installation.

The electronic Oil Level Controller monitor the oil level in the compressors crankcase, and in case of oil lack is capable of directly try to restore the oil or give an output signal.
They have been designed to be mounted directly onto various types of compressors.

The optical sensor monitors the level of the liquid by electro-optic infrared technology.

The electronics is designed to control the oil level of the compressor by activating a solenoid valve for automatic oil filling and integrates also a separate alarm contact.
The oil level controller can be customized to function with various brands of compressors available worldwide.
