Case info
ZOZEN’s WNS series gas boilers have automatic operation and interlock protection functions, which are very easy to operate and greatly reduce maintenance costs. The wet-back structure of the boiler body ensures the safety and reliability of the equipment;
In addition, the large diameter corrugated hearth not only reduces thermal stress, but also ensures sufficient heating surface and steam storage space; the spiral finned tube energy saver at the end of the boiler raises the boiler inlet water temperature and reduces the exhaust smoke temperature, making the boiler thermal efficiency as high as 98%, which is better than the national energy efficiency standard.
