In the modern multifunctional meeting room, there is a lot of domestic and international certification acquired by ZOZEN including the A-grade boiler and BRⅡ-grade pressure container manufacturing licence, ASME “S” (utility boiler), “U” (pressure container) steel seal licence of USA and ISO9001 international quality system certification.

Under the background of increasingly fierce market competition and rising comprehensive costs, Mengniu Dairy always adheres to the concept of sustainable development. When purchasing boiler equipment, it uses clean energy natural gas as fuel to reduce environmental pollution. So far, Mengniu Dairy has purchased more than ten sets of WNS series gas-fired steam boilers from ZOZEN.

The SZS series oil-fired/gas-fired boiler proper adopts the D-type structure. One side is the furnace, and the other side is the convection heating surface. The partition walls around the furnace body, the partition wall between furnace and convection section, and the front and rear walls all adopt the membrane wall structure. There are foreign advanced burner, economizer and condenser installed at the end of flue gas duct, which can lower the exhaust gas temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. This kind of boiler has the characteristics of energy saving and environmental protection, safety and efficiency, simple operation and maintenance, and fully automatic control system which can realize unattended operation, gas condensing steam boiler.

Since its foundation in 1996, Happy Alliance (M) Sdn Bhd has developed into one of the leading Nata De Coco manufacturers in Malaysia. It has established the well-known brand Captain Dolphin. Steam boiler is used to provide heat source for the production processes of cooking, drying, and sterilizing in food industry. In order to save the fuel cost, Happy Alliance (M) SdnBhd decided to use coconut shells as boiler fuel. In this case, ZOZEN’s engineers recommended one set of 4 tph biomass-fired fire tube boiler for the company.

ZOZEN WNS series boiler is designed with large-diameter corrugated furnace and wet-back structure. Depending on the velocity of different flue gas, proper heat transfer element will be selected. Advantages：high efficiency, low back pressure, ultra-low NOx emissions.
