Oil separators are installed at the compressors discharge line. They’re usually a vertical container with the discharge gas connections at the top and an oil return port at the bottom.
The function of an oil separator is to separate oil from the hot gas in the discharge line and return it to the compressor crankcase or to the oil reservoir in systems with multiple compressors.
Its ensuring efficient lubrication of the moving parts in compressors.
The use of an oil separator leads to:
• Longer compressor life;
• Better performance of the whole system with consequent energy savings;
• Quieter operation by reducing pulsing.
