Compressor - Wikipedia

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.An air compressor is a specific type of gas compressor.. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe.As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while

"Feedforward" is a rather under-used control strategy capable of managing a great many types of process problems. It is based on the principle of preemptive load counter-action: that if all significant loads on a process variable are monitored, and their effects on that process variable are well-understood, a control system programmed to take appropriate action based on load changes will

How do heat exchangers work? - Explain that Stuff

May 04, 2021 · Hot water is piped through it from a gas central heating boiler, giving up some of its heat to the air in the room in the process and returning to the boiler for more. This is a sort of heat exchanger because the heat from one fluid (the hot water in the pipe) is being given to another fluid (the cold air in the room) without the two fluids mixing.

Reliable air compressors with high energy efficiency

The average factory changes air compressors every 7-10 years, meaning that the initial capital expenditure is only a fraction of how much your compressor will cost you in total. It may surprise you to find out that 70% or more of your air compressor's lifecycle cost will come down to its energy usage.
