Compressors

• Consider variable speed drive for variable load on positive displacement compressors.
• Use a synthetic lubricant if the compressor manufacturer permits it.
• Be sure lubricating oil temperature is not too high (oil degradation and lowered viscosity) and not too low (condensation contamination).
• Change the oil filter regularly.
• Periodically inspect compressor intercoolers for proper functioning.
• Use waste heat from a very large compressor to power an absorption chiller or preheat process or utility feeds.
• Establish a compressor efficiency-maintenance program. Start with an energy audit and follow-up, then make a compressor efficiency-maintenance program a part of your continuous energy
management program.
