Product Description

1.Product Description
1, High efficient and reliable;
2, Fully automatic control and running
3, Three-pass and wet-back structure
4, Threaded tube: Strengthen the heat transfer, increase the boiler heat efficiency

2.Features:
1. Adopting tried and tested three-pass and wet-back structure, more safe and reliable
2. Big combustion room design: Increase furnace radiant heating area, decrease the boiler size, reduce the emission of the NOx
3. Corrugated hearth make the boiler more safe
4. Threaded tube: Strengthen the heat transfer, increase the boiler heat efficiency
5. Multi-level sealing for flue gas chamber: No flue gas leakage
6. Boiler controlling system can run for a long time under high temperature and high humidity condition
7. Multi-level protections like boiler pressure, hot water temperature, gas pressure protection and so on.
8. High efficient thermal insulation material, low boiler surface temperature, the heat loss can be neglected
9. Produce according to the national standard, all pressurized components apply fine quality steel
10. Every boiler must be subject to strict inspection and testing before delivery, including hydraulic test and X-ray inspection
11. Selecting the most suitable burner to match the boiler so as to guarantee safety and reach rated output
12. All components, such as pumps, valves are limited to choose international or national renowned- brands.
13. Introducing manhole and hand hole: Maintenance is convenient customer-tailored design is available.
14. An economizer is optional and possible to save 15% fuel, decrease noise 20dB.

3. Advantages of our production and service
1), 100%safety, running stably, excellent water level and pressure control, fully automatic operation
2), Boiler running life > 20years.
3), Good after-sale service. It is free for you to get the damaged spares in warranty period(1 year) if there is any questions. Assure that we can supply you spares in boiler's all life.
4), We can arrange engineer to your company for installation and commissioning and training. If you need us at any time, we can send our technicians and prepare in a short time.
5), Special paint is used after assembly. Paint is particularly used in your climate area, which is anti-corrosion, anti-abrasion and color-fastness.
