从China供应商批发进口Adblue Emission Fluid Heater-Urea Fluid Heater — FOB条款

Zhejiang Jinjia Auto Parts Co., Ltd. manufactures a DEF fluid heater assembly designed for installation within the urea reservoir of Volkswagen Passat vehicles, with cross-reference to part number 561198970. The unit integrates a heating element, liquid level sensor, and temperature sensor within a single plastic reservoir module. This addresses the critical need to maintain DEF fluidity in cold climates, as the 32.5% urea solution freezes at -11 degrees Celsius and would otherwise disable the SCR system.

The heater operates by raising urea temperature through an integrated heating device, enabling pumpable fluid delivery to the SCR dosing module even in sub-zero conditions. A liquid level sensor provides precise height measurement for on-board diagnostic monitoring, while the temperature sensor feeds back reservoir thermal status to the engine control unit. The plastic reservoir construction offers chemical resistance to urea solution and mechanical durability within the underbody environment. Typical materials include glass-filled polyamide or POM for the reservoir body, with stainless steel or ceramic elements for the heater core to resist urea corrosion and thermal cycling fatigue.

This assembly targets automotive OEM aftermarket, independent parts distributors, and specialist diesel service operations servicing Euro 5 and Euro 6 passenger vehicles in cold-climate markets. Buyers should confirm exact vehicle application coverage beyond the stated VW Passat reference, electrical specifications including voltage and current draw, and whether the unit carries automotive quality certifications such as IATF 16949 or component-level EMC compliance.

Zhejiang Jinjia Auto Parts Co., Ltd. is based at No.369 Road, Kaifa Yilu Development Zone, Ruian City, Zhejiang Province, China, postal code 325200. Ruian is a recognised concentration of automotive parts manufacturing in China, with extensive supplier networks serving both domestic vehicle assembly and export aftermarket channels. The company holds a harbour trust tier on the platform, with a 0.00% response rate and zero recorded average response hours, indicating no recent tracked buyer interactions.

The listing describes Zhejiang Jinjia as producing integrated DEF heater-sender units with emphasis on high integration, rapid heating, and precise liquid level sensing. No workforce size, annual revenue, years in operation, or specific certification details are provided in the source data. Buyers should independently verify IATF 16949 quality system status, OEM approval credentials, and laboratory testing capabilities before placing volume orders.
