Tank heating is the process of hot water cleaning, degreasing and phosphating the car body before pre-treatment electrophoresis. The traditional heating process is to use boilers to heat high-temperature steam or hot water for heat exchange. The equipment is complex, the boiler (special equipment), the thermal efficiency is low, and the operating cost is high. J.Parker uses gaseous fuels such as natural gas and liquefied petroleum gas for combustion. The burner flame is in the water tank heating pipe, and the hot flue gas is discharged along the heating pipe. The cold water in the tank is fully exchanged to form a stable hot water source. J.Parker provides a complete combustion system. According to the specific space of the project site, the burner, fuel valve skid and control cabinet are integrated together
