horizontal hot water boiler WNS4.2-1.0/95/70

Functions

 Adopting tried and tested three-pass and wet-back structure, more safe and reliable
Big combustion room design: increase furnace radiant heating area, decrease the boiler size, reduce the emission of the NOx
Corrugated hearth make the boiler more safe
Threaded tube: strengthen the heat transfer, increase the boiler heat efficiency
Multi-level sealing for flue gas chamber: no flue gas leakage
Boiler controller system can run for a long time under high temperature and high humidity condition
Multi-level protections like boiler pressure, hot water temperature, gas pressure protection and so on.
High efficient thermal insulation material, low boiler surface temperature, the heat loss can be neglected
Produce according to the national standard, all pressurized components apply fine quality steel
Every boiler must be subject to strict inspection and testing before delivery, including hydraulic test and X-ray inspection
Selecting the most suitable burner to match the boiler so as to guarantee safety and reach rated output
All components, such as pumps, valves are limited to choose international or national renowned- brands.
Introducing manhole and handhole: maintenance is convenient
