American Geothermal

american geothermal's air blast system is a direct instantaneous aggregate heating system. We can also cool with an optional cooling system addition. The system is designed to direct large volumes of warm air directly through overhead aggregate bins. The system can heat coarse aggregate and sand at rates of up to 200 yards per hour. Since all of the heat is going into the aggregate, the operating cost is far less than other methods of heating aggregate. here are some of the air blast system benefits: * direct heat by gas-fired burners. * low operating costs per volume of aggregate heated. * reduces or eliminates the need for hot water for aggregate heating. * eliminates frozen materials. * eliminates the rusting of the plant through the use of steam and the related freeze/thaw problems. * optional cooling feature can provide up to a 25 degree f drop in concrete temperatures.
