Smith water heater Jin GUI te Hu
A.O. Smith innovated and developed Jingui special care heating rod, which made a breakthrough in anti-corrosion and anti-pollution ability. Jingui special protection system composed of Jingui inner container and American strong anode rod improves the overall quality of water heater and ensures long-term and efficient operation.
1) patent Jingui special protection heating rod: long-term efficient heating, durable and energy-saving: Jingui coating is tightly protected, durable and antifouling. Low fouling ensures that the heating rod maintains high heat transfer efficiency and runs efficiently for a long time.
2) Patent Jingui special protective liner: the coating does not fall off: fiber is added to the special glaze, baked at 870℃, and it adheres tightly and does not fall off. The coating does not break: the coating expands and contracts synchronously with the steel plate of the liner without breaking, which is more effective in corrosion prevention and scale prevention.
3) High standard bearing capacity: under the strict "UL" standard, it passed 6,543,800 life tests. Cutting-edge technology eliminates virtual welding and ensures the pressure-bearing performance of the liner structure. Each batch of liners has passed the pressure test of 2 1 kg/cm2, which can ensure the safety even if the temperature changes.
