The Heat Lance is used to dry and prepare pavement cracks, potholes, and other distressed pavement surfaces for repair. It offers separate valves that control the mixture of fuel and compressed air at the point of combustion. The Heat Lance is capable of producing heat up to 2,600o F, with a velocity of 3,000 feet per second. The combustion chamber is constructed from stainless steel for lasting durability. All fuel is ignited before exiting the burner tube, providing flameless hot air at the point of pavement contact. The Heat Lance comes standard with a wheel kit, a 40-foot hose, an LP gas regulator, an air regulator gauge, a water separator, standard Chicago tank fittings, and abrasion wrap with quickconnect fittings. Lance weight is approximately 9.2 pounds with a one-year warranty against material defects and workmanship
