Air Receiver Tank Design

As air sits in the tank or slowly flows through it it naturally cools over time.

Air receiver tank design.

The tank is a reservoir of compressed air that can be used during peak demand. Air receiver tanks are sized in gallons and can range from small 5 and 10 gallon tanks to massive tanks that hold thousands of gallons of air. P 2 minimum tank pressure psia example sizing an air receiver. Efficiency benefits of air receiver tanks.

Lowering the temperature of the air an additional 5 10 f is not uncommon. The air receiver tank supports the work of a primary heat exchanger. 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. Visualization of the receiver tank concept.

The air receiver tank acts as a secondary heat exchanger. Normally installed after drying and filtration and before end use devices receiver tanks help to store compressed air. An air receiver tank is an important component of a compressed air system. 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.

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 tank is sized 6 10 times the flow rate of the compressor system. V t c p a. The receiver tank is usually 150 cubic feet minimum for compressors with a rating of 25 scfm at 100 psi.

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.
