The German automotive industry has always been a pillar industry of the national economy, owns the world-class automotive brands such as Audi, Mercedes-Benz and BMW. And, Germany's auto parts industry is also very developed, which has established an important foundation to support the healthy, stable and rapid development of the auto industry.

The shock absorber is an important part of the vehicle suspension system. This metal-based auto part requires the treatment of the metal surface. Otherwise, it is prone to corrosion damage. GOTEC Group has a global market share of 55% in the surface treatment part of the shock absorber, providing support service for recognized car companies such as BMW, Ford and Audi. In the process of chemical heat treatment, thermal spraying and other processes on the surface of the shock absorber, the industrial boiler plays an irreplaceable role as a piece of important supporting heat source equipment.

In 2014, GOTEC Group set up Gotec Automotive Technology (Suzhou) Co., Ltd. in China and introduced ZOZEN WNS series gas fired boilers to provide a stable heat source for thermal treatment and spraying of shock absorbers. GOTEC spoke highly of the boilers due to their high efficiency and sufficient steam output.

With the development of global economic integration, GOTEC Group has set production and sales bases in Poland, Spain, USA and Brazil. This time, GOTEC Group built a new plant in Toluca, Mexico, to expand its world map. As the important energy equipment for a new plant, the efficient and stable operation of the gas-fired boilers would directly affect the company's production efficiency and product quality.

Based on previous friendly cooperation with ZOZEN, GOTEC Group contacted ZOZEN and put forward more detailed requirements for the new system of boiler automation control.

Aiming at the characteristics of load changes in the actual production process of the Mexican plant, ZOZEN equipped the easy-to-operate PLC automatic control system for the boilers. The PLC automatic control system adopts advanced frequency conversion technology and fuzzy control technology to achieve high-efficiency and energy-saving operation by changing the gas volume of the boiler. After the automatic function is turned on, the controller can also automatically control the system according to the mode set by the user to ensure the safe and stable operation of the boiler.

In addition, WNS series gas fired boilers use large-diameter corrugated furnaces and threaded smoke tubes in conjunction with the energy-saving devices at the tail of the flue, to reduce exhaust temperature to 60 degrees and improve the thermal efficiency over 98%.

The recent round of cooperation with GOTEC Group not only marks their recognition of the high quality of ZOZEN, but also indicates that ZOZEN has obtained strong competitiveness in the international market.
