Air receiver tank design.

The air receiver tank supports the work of a primary heat exchanger. Efficiency benefits of air receiver tanks. A receiver tank is a form of dry compressed air storage in a compressed air system. 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.

The tank is a reservoir of compressed air that can be used during peak demand. 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. Lowering the temperature of the air an additional 5 10 f is not uncommon. As air sits in the tank or slowly flows through it it naturally cools over time.

The compressed air is created by the supply side stored by the receiver tank and released as needed to the demand side of the system. The air receiver tank acts as a secondary heat exchanger. 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. The receiver tank is usually 150 cubic feet minimum for compressors with a rating of 25 scfm at 100 psi.

V t c p a. Normally installed after drying and filtration and before end use devices receiver tanks help to store compressed air. An air receiver tank increases the amount of air available on demand allowing for higher duty cycles and more powerful applications. Visualization of the receiver tank concept.

An air receiver tank is an important component of a compressed air system.
