Dual-Fuel Road Marking Preheater is a machine used to melt road marking coatings. During marking construction, the powder coating is first heated and stirred using the hot melt kettle until it turns into a liquid state. Then, the coating is placed in the marking machine for marking construction. Due to the direct relationship between the melting quality of coatings and the quality of marking, the hot melt kettle is a key component of the hot melt marking equipment. It is an essential part of the melting of coatings.

The diesel and gas dual-purpose hydraulic dual cylinder hot melt kettle can freely choose diesel or liquefied gas as the heating fuel based on factors such as temperature, region, and fuel cost. It is the main equipment for melting coatings in hot melt marking construction.
