Green – Fast – Cure technology works by mixing fresh air and gas for a more effective infrared cure, capturing time and energy savings for you. This technology is patented and approved by CSA International. GFC technology uses a mixture of fresh air and gas fuel to provide an oxygen rich atmosphere for better oxidation of the fuel and to generate the amount of “amplitude” power necessary to reach long distances with the effective infrared for curing application. The “pressure” design into the venture/injection system maintains the amplitude to allow the GFC products to have the necessary power of infrared distances from 6 to 8 feet.
