horizontal return tubular boiler systems, ZOZEN WNS series boiler adopts the corrugated furnace to increase the heating surface
After more than 30 years of development, Wuxi Zozen Boilers Co., Ltd. has made outstanding achievements in various industries. Recently, the ZOZEN WNS series gas-fired steam boiler has established a high-temperature sterilization safety line for the production of contact lenses, which has promoted the healthy development of the entire industry, horizontal return tubular boiler systems.

All equipment (includes boiler proper, economizer, burner, valves, instrument, electric control cabinet, chimney, water treatment, softened water tank, energy-saving circulating pump, raw water pump, deaerator, etc.) is designed to be installed on one or two prepared concrete bases. ZOZEN skid mounted boiler has all interconnecting piping completed and has passed the cold state test at the factory before delivery. After the boiler arrives at the site, it only needs to be connected to water, electricity and gas to operate.
horizontal return tubular boiler systems, ZOZEN boilers adopt the ultra-low nitrogen burner with flue gas recirculation method to realize low NOx emission. Adding flue gas to the combustion air to reduce the oxygen content in the combustion air and lower the flame temperature at the combustion center, so as to greatly reduce the generation of NOx. At the same time, superimposed use of world advanced technologies such as staged combustion of ultra-low nitrogen burner and internal flue gas circulation realizes the stable and low emission of NOx.
Wuxi ZOZEN Boilers Co., Ltd. takes the lead in integrating the programmable controller and touch screen in piping, electrical installation and electrical control, and applies them to the operation control of the boiler. It can realize various modern control functions such as automatic boiler control, networked device control, computer group control and remote control. The first-class hardware, practical and safe software technology ensure the fully automatic production and high-quality operation.
As a leader in the industrial boiler manufacturing industry, ZOZEN has won the recognition and trust of many well-known enterprises in Henan Province such as Keming Noodle, Xinzheng Thermal Power, Tongyuan Pharmaceutical, Zhengyang Luhua and Yuzhu Instant Noodle by virtue of the SZS series gas-fired low-NOx boilers with the technical advantages, quality assurance and one-stop services.
horizontal return tubular boiler systems, In the future, ZOZEN Boiler will further expand the business in the Colombian market, and use Colombia as the entry point to gradually radiate markets in Brazil and Chile, which is expected to open up a new situation in the South American market. Meanwhile, in the boiler industry, the good performance of ZOZEN Boiler in overseas markets has also played a positive role in promoting the high-end and international image of ZOZEN brand to further consolidate the leading position in energy-saving and eco-friendly boiler field, which provides a set of good development ideas for Chinese boilers and even Chinese brands to go to the world.
