Thermal fluid heaters are indispensable equipment in chemical industry, which are used to provide heat energy for the distillation, rectification, hydrofining and other processes. Shenghongxiang Chemical Industry Co., Ltd. located in Henan, mainly produces purified petroleum benzene, methylbenzene, dimethylbenzene, heavy benzol, light benzol and other coal chemical industrial products. With increasing environmental awareness, Shenghongxiang Chemical Industry Co., Ltd. has weeded out the original boilers, whose flue gas emission cannot reach the latest environmental protection standard. This time, they have made a decision to order several eco-friendly thermal fluid heaters. ZOZEN uses unique technology for production of thermal fluid heaters. Therefore, ZOZEN’s thermal fluid heaters, which have created good reputation in kinds of industries, are superior to others in the quality and environmental protection performance. At last, Shenghongxiang Chemical Industry Co., Ltd. has chosen ZOZEN’s 6MW horizontal type gas-fired thermal fluid heaters after recommendation. This kind of thermal fluid heater adopts 3-pass round coil tube design for sufficient heating surface, making thermal efficiency reach above 98%. The advanced combustion apparatus is used for low NOx emissions. Furthermore, it has a complete control system and safety monitoring device that can accurately control the working temperature and ensure stable operation.
