Types of Compressors and compressor selection

By: Grant Laidlaw (F. SAIRAC) – ACRA CEO

In the last issue we looked at the first section involving types of compressors and now move on to power supply

In areas where only limited or no electrical power is available, compressors can be driven by internal combustion engines. In this case only open type compressors are suitable. It is possible to generate power with a generating set, though, because of the high currents required to start compressors, it is often not a proposition to provide a big generator to start the compressor which then runs at reduced capacity.
