An air receiver is used to store high-pressure air from the compressor. These equipment are used to storage compressed air before entering to piping or pneumatic system. Its volume reduces pressure fluctuations arising from changes in load and from compressor switching.
Air coming from the compressor will be warm (if not actually hot!) and the large surface area of the receiver dissipates this heat to the surrounding atmosphere. Any moisture left in the air from the compressor will condense out in the receiver, so outgoing air should be taken from the receiver top.
MVH Global can supply the black start/emergency compressor with different capacity and pressure from well-known qualified brands.
