![]() Reduce Operating Pressure for the Air CompressorĬompressed air storage also allows you to reduce the pressure at which your air compressor operates. A properly sized air storage tank reduces frequent cycling and venting. Over time, this adds up to the loss of thousands of cubic feet of compressed air that could otherwise have been used to power processes in your facility. Compressed air is released during the venting. Every time a rotary screw air compressor unloads, the sump tank (oil tank) is vented. Increasing the efficiency of the air dryer by reducing moistureĪs the air compressor cycles on and off, compressed air can be wasted.Lowing the pressure requirements for the air compressor and air network.Reducing waste of compressed air from excessive sump blowdowns.Efficiency Benefits of Air Receiver TanksĪdding an air receiver tank significantly improves the efficiency of your compressed air system. The air receiver tank supports the work of a primary heat exchanger lowering the temperature of the air an additional 5 – 10☏ is not uncommon. The air receiver tank acts as a secondary heat exchanger as air sits in the tank or slowly flows through it, it naturally cools over time. A heat exchanger is used to remove excess heat caused by compression. The condensed air must be cooled and dried before it is utilized. Hotter air also contains more moisture, which will result in excess water vapor that will condense in control lines and tools if it is not removed. This is too hot for most air-operated equipment to use directly. Depending on the type of air compressor you are using, the air discharged from the compressor may be as hot as 250 – 350☏. Heat ExchangerĪs air is compressed under pressure, its temperature increases this is a simple law of physics known as the Pressure-Temperature Law. The air receiver tank eliminates short cycling and provides more consistent system pressure to controls. Rapid cycling can result in excessive wear of the motor contactor or even a direct motor short because of winding insulation. Over time, frequent short cycling will lead to premature failure of switches and other compressor components. Each time the system turns on and off (or loads/unloads) is called a “cycle” it is better for the compressor motor to keep these cycles as long as possible. ![]() Uneven compressed air utilization causes uneven demand on the air compressor, resulting in rapid cycling of the compressor controls as the compressor turns on and off to meet moment-by-moment demand. The air receiver tank provides a steady stream of air to compressor controls, eliminating short-cycling and over-pressurization. Using an air receiver tank may also allow you to use a smaller horsepower compressor for larger jobs. Storing compressed air reduces sudden demands on your air compressor, prolonging the life of your system. The air in the tank is available even when the compressor is not running. This air can be used to power short, high-demand events (up to 30 seconds) such as a quick burst of a sandblaster, dust collector pulse, or someone using a blowgun to dust themselves off. ![]() You can think of your air receiver tank as a battery for your compressed air system, except it stores air instead of chemical energy. Storing compressed air allows the system to average the peaks in compressed air demand over the course of a shift. The primary role of an air receiver tank is to provide temporary storage for compressed air. When used as a “wet tank”, it acts as a secondary heat exchanger, increasing the efficiency of your air dryer.It provides a steady air signal to compressor controls.It stores compressed air that can be used for short, high-demand events.The air receiver tank has three main functions in your compressed air system: It also helps your air compression system run more efficiently. The Purpose of an Air Receiver TankĪn air receiver tank provides temporary storage for compressed air. The tanks come in a range of sizes and in both vertical and horizontal configurations. This gives you a reserve of compressed air that you can draw on without running your air compressor.Īn air receiver is a type of pressure vessel it holds compressed air under pressure for future use. What Is a Compressed Air Receiver Tank?Īn air receiver tank (sometimes called an air compressor tank or compressed air storage tank) is what it sounds like: a tank that receives and stores compressed air after it exits the air compressor. Before you buy compressed air receiver tank, take some time to learn about the device itself. Our guide to compressed air receiver tanks explains how they work, what they do, and how you can use them to maximize the efficiency of your compressed air system.
