HVOF / Thermal Spray / Flame Spray / Metal Spray with natural gas

ASB Industries in Barberton, Ohio replaced propylene with high pressure natural gas and cut fuel gas costs by $10 per operating hour, eliminated downtime from gas reliquification in the spray gun and stopped refilling dozens of empty gas cylinders.

A G-TEC Torch Booster can be installed right next to your metal spraying equipment -

no need for an expensive compressor that requires an outdoor concrete pad !

Brochure - HVOF with high-pressure natural gas

High pressure natural gas is an excellent fuel for High Velocity Oxy-Fuel (HVOF) thermal spray, flame spray, combustion guns and similar metallizing applications.





Outdoor compressor costs more and is more expensive to install

Until now using natural gas required a large, expensive compressor installed outdoors on a concrete pad with expensive welded high pressure piping running through the building to the HVOF booth. Frequently a building permit is required to install this type of compressor.

TB-500H Torch Booster includes a Booster Module (right) and Cooler Module (left) connected by 5’ flexible  hoses. The system is compact, quiet and designed to be installed right next to the spray booth. Each cabinet is 28” wide, 20” tall and 24” deep- the Cooler Module can be stacked on top of the Booster to minimize footprint space. Utility natural gas supply should be 1/4psi (7” WC) to 5 psi

TB-500H Torch Boosters

TB-500H Torch Booster supplies 150 psi natural gas at a flow rate

up to 500 scfh (50000 BTU) from a ¼ psi utility natural gas supply.


TB-500H is easy to use...just turn it on and it is ready for immediate service

- there are no storage tanks to fill. The only controls are ON and OFF because

the Booster automatically adjusts to the gas flow used by your spray gun. When you are not spraying the Torch Booster automatically goes into recirculation mode. It is designed to be left running for short periods when the spray gun is not being used such as during breaks, lunch or while setting up the next spray job. It does not require operator attention as the spray gun is turned on and off.


Both TB-500H cabinets measure 28” W x 24” D x 20” T. The Booster Module weighs 330 pounds and the Cooler Module weighs 157 pounds. In North America electrical requirements are 208V, 60Hz, 30 amp service; Worldwide 230V, 50Hz, 30 amp service. Gas supply should be between ¼ to 5 psi and delivered in a 1 1/2” pipe which connects directly to the Torch Booster.


TB-500H Torch Booster connects to the building utility natural gas pipe with a 1 1/2” diameter pipe that reduces to 3/4” diameter at the Booster. One inlet is for gas supply under 1 psi and a second for gas supply between 1-5 psi.
