By Ron Marshall A mine located in northern Canada has a compressed air system used to generate 150 psi compressed air for diesel engine starting duty. Due to the failure of the original compressor, a new compressor was purchased as a replacement. The previous compressor operated in load/unload mode with timed shutdown. This ensured the […]

Compressed air fail: High discharge pressure
By Ron Marshall for the Compressed Air Challenge An automotive manufacturer was having trouble with its large centrifugal compressors, which were constantly going into surge condition. This is a damaging condition where the air going through the compressor suddenly stops and starts, shocking the fast spinning rotors in the machines and causing stress on the internal […]

How important are storage receivers to my screw compressor?
If you have one or more lubricated screw compressors that run partially loaded in load/unload mode, the size of the storage receiver is quite important to the compressor operating efficiency—and may affect its lifespan. If your compressors run in modulation mode, the least efficient way to run a screw compressor, the compressor efficiency is likely […]
