A Vulcan Catalytic heating system is controlled with state-of-the-art UL approved controls, which incorporate our unique gas pulse technology (GPS). Proved and tested for many years GPS is the most economical method of providing multi zone capability for catalytic ovens via PLC based controls. GPS carefully meters precise volume pulses of gas, ensuring ideal temperature settings while allowing for multi zoned heating arrays. The Vulcan Gas Pulse System incorporates a recipe-based menu which interfaces with digital output cards. Operators call up the recipe on the touch-sensitive PLC screen and the system automatically sets the control using the Gas Pulse System.
