You can choose built-in coal-fired or diesel dual-mode heating system. The insulation layer is made of high-temperature-resistant rock wool and polyurethane composite structure, which can keep the asphalt temperature above 160 ℃ for up to 72 hours. The spiral heat conduit design ensures even heating of the material, and with the hydraulic lifting and unloading port, the flow of paving asphalt can be precisely controlled. Key application scenarios include highway maintenance and municipal engineering construction.
