ZOZEN has been a leading industrial manufacturer after more than 30 years of development. In recent years, with the increasingly strict environmental protection policies, ZOZEN has intensified great efforts in the research and development of gas-fired boiler products and improving the environmental performance and overall thermal efficiency of boilers. As a star product of ZOZEN environment-friendly boiler, the WNS series gas-fired boiler adopts an advanced low NOx burner. In addition, ZOZEN optimizes the design of furnace size, volumetric heat load, and the flue gas flow rate of the convection area to ensure that the NOx emission is less than 30mg / Nm3. In terms of improving the thermal efficiency of the boiler, ZOZEN adopts threaded smoke tubes to enhance the heat transfer effect. Meanwhile, through the application of condensation technology, the sensible and latent heat in the high-temperature flue gas can be fully absorbed, which can increase the inlet temperature and improve the
With features of low pressure and high temperature, ZOZEN various series of thermal oil heaters have become heat source of many chemical enterprises. ZOZEN YLW series coal-fired(biomass-fired) thermal oil heater is a square coil horizontal chain grate shop-assembled heater of which the chain grate and heater proper are transported separately. Once connected the oil and electricity, the heater can be put in use. This series of heater adopts an advanced structure, including four parts: the radiation furnace heating area, convection tube bundle heating area, waste heat boiler and air heater, which has sufficient heating area and ensures high thermal efficiency of the boiler. Meanwhile, ZOZEN reasonably designed the combustion chamber according to different characteristics of different types of coal and biomass fuel, which not only ensures the complete combustion of the fuel but also improves the combustion efficiency and reduces the formation and emission of flue gas. This series of heate
Confronted with the increasingly severe environmental protection policies, ZOZEN has made progress in the research and development of technologies in recent years. WNS series gas-fired boilers with features of high efficiency and low emissions are preferred by the industrial boiler market. This series of boiler adds a radiant heating surface to increase the heat transfer coefficient. Besides, the boiler adopts high-efficient threaded flue tubes to slow down the flue gas flow rate and fully absorb heat. In addition, energy-saving devices are equipped at the tail of the flue to increase the thermal efficiency to above 98%. The efficiency is superior to level 1 national energy efficiency standard. Moreover, the advanced low NOx burner greatly reduces the emission of NOx to 30 mg/m３. The ultra low emission provides guarantees for clean production and sustainable development of enterprises.
Tianjin Normal University is a key construction college of the provincial and ministerial level in Tianjin. It has more than 30,000 faculty members and students. Ensuring such a large group warm in winter is a very important task for the school. Therefore, in the choice of boiler suppliers, Tianjin Normal University conducted a full market research in a rigorous manner.
In the manufacturing process of all kinds of chemical auxiliaries, the key process of concentration needs steam support produced by steam boilers, which direct affect the quality and performance of chemical auxiliaries. Jiangsu Han Kuang Industrial Co., Ltd. has become one of the national largest production bases of petrochemical auxiliaries. With a sudden increase in market demands, Han Kuang Industrial decided to introduce a branch of equipment that equipped with automation systems to accelerate the intelligent transformation of environmental protection and safety. Han Kuang Industrial planned to purchase environmental friendly and high efficient steam boilers featuring automatic and safe operation. After a series of careful and rigorous market research, Han Kuang Industrial reached cooperation intention with ZOZEN and ordered 2 sets of 4 tph WNS series condensing gas-fired boilers (WNS4-1.6-Q). The full automatic intelligent control ensures the long-time safe and stable operation o
As the essential thermal equipment in rubber industry, steam boilers are widely used in the processes of rubber calendering, vulcanizing and drying; the performance of boilers has a direct impact on the economic benefits of the company. Located in North Sumatra, Indonesia PT.Industri Karet Deli is a large rubber enterprise founded in 1956. The company's line of business includes the manufacturing of pneumatic casings, inner tubes, and solid and cushion tires for all types of vehicles.

ZOZEN is an industrial boiler manufacturing enterprise with strong comprehensive strength, has obtained a variety of international certifications including ASME; what’s more, ZOZEN has achieved fruitful results in the international market. ZOZEN won the trust of PT.Industri Karet Deli with rich experience in the rubber industr
Steam boilers play a key role in the production and processing of pressed vegetable, providing heat source for emulsifying and sterilizing. Chongqing Fuling Zhacai Group Co., Ltd. is a large-scale agricultural industrialization enterprise group, its leading products Wujiang series pressed vegetable is widely known and sold well in China, and has exported to many regions and countries such as the European Union, the United States and Japan.
As the environment pollution has become more and more serious in recent years, Fuling Zhacai decided to upgrade its existing equipment, promoting the transformation of pressed vegetable exploitation and utilization from extensive form to intensive and environment friendly form. Fuling Zhacai was in desperate need of introducing more environmental friendly boilers to ensure the NOx in flue gas emission below 30mg/Nm3, the boilers are the important facilities of the production line. ZOZEN stood out in the in the competitive bidding competition with r
