Air Receiver Tank Design

The air receiver tank supports the work of a primary heat exchanger.

Air receiver tank design.

Visualization of the receiver tank concept. An air receiver tank is an important component of a compressed air system. An air receiver tank increases the amount of air available on demand allowing for higher duty cycles and more powerful applications. Efficiency benefits of air receiver tanks.

The receiver tank is usually 150 cubic feet minimum for compressors with a rating of 25 scfm at 100 psi. The tank is sized 6 10 times the flow rate of the compressor system. The tank is a reservoir of compressed air that can be used during peak demand. As air sits in the tank or slowly flows through it it naturally cools over time.

Normally installed after drying and filtration and before end use devices receiver tanks help to store compressed air. The ideal size of an air receiver tank will depend on the type of. Lowering the temperature of the air an additional 5 10 f is not uncommon. P 2 minimum tank pressure psia example sizing an air receiver.

It is important to remember that higher pressure does not equal more flow cfm or l s but just the opposite as we raise pressure the flow decreases. Each air receiver should be equipped with a pressure relief valve which is designed to release pressure from the tank in case the tank reaches its maximum allowable pressure inside the vessel. For an air compressor system with mean air consumption 1000 cfm maximum tank pressure 110 psi minimum tank pressure 100 psi and 5 sec time for the receiver to go from upper to lower pressure the volume of the receiver tank can be calculated by modifying 1 to. A receiver tank is a form of dry compressed air storage in a compressed air system.
