A letter from Zhongnu Bearing Heater to a distributor in China

**A Letter from Zhongnu Bearing Heater to Distributors in China** Since its first production of bearing heaters in 1996, China Connaught Instrument has come a long way. From the initial manual-controlled ZN series to the second-generation microcomputer-controlled ZNE/ZNY series, and now to the third-generation high-quality platinum bearing heaters, our company has continuously improved its technology, focusing on safety, environmental protection, and top-tier quality. The ZN series was designed with simplicity and affordability in mind, making it ideal for domestic use. It helped transition from oil bath heating or damaging methods to electromagnetic induction heating, significantly improving efficiency. However, the control systems had limited accuracy, leading to imprecise temperature settings. This prompted us to develop the second generation—ZNE/ZNY series—with microcomputer control, offering precise temperature and time settings down to 0.1°C and 1 second. These models also featured an automatic heat preservation function, ensuring uninterrupted heating even when users were away. As market demands evolved, customers began seeking more durable, efficient, and eco-friendly solutions. In response, we upgraded the second-generation heaters with enhanced internal components and improved design. The third-generation platinum bearing heaters represent the pinnacle of this progress. They are built using imported cold-rolled silicon steel and pure copper coils, resulting in higher efficiency, better performance, and reduced energy consumption. These heaters come with a three-year warranty, ensuring long-term reliability and minimizing maintenance costs. Additionally, the new design includes better heat dissipation and ventilation systems, enhancing both functionality and aesthetics. Our commitment to continuous improvement ensures that our products meet the growing needs of the market while promoting sustainability and cost savings. Beyond product development, we also invest heavily in marketing and brand promotion through print and online media. We support our distributors by providing strong after-sales service, including annual on-site inspections by professional engineers. This helps maintain customer satisfaction and strengthens our business relationships. If you're interested in our distribution policies, feel free to contact our dealer hotline at 18262318318. We are confident that working together will lead to mutual success. Let’s continue to grow and achieve great things in the coming year!
