central heating system CWNS0.7-90/65

Shining points:
- This product has synthesized the merits of atmospheric pressure boiler and pressurized boiler.
- Patented technology: the body designed according to atmospheric pressure type and a built-in 1.0MPa pressure copper heat exchanger, effectively solved the problem of providing heating and clean hot water for top buildings.
- Bi-coil pipe technology: providing hygienic water and hot water for different use in the same time is available.

Features:
1. Tubes with horizontal furrows: improve heat efficiency.
2. Big combustion room: increase radiated area, decrease emission of NOx.
3. Big flue gas tube: reduce the resistance of smoke flowing and consumption of electricity.
4. Intelligent control system: multi-boiler control and remote control is available.
5. Compressed fin-tubes without cutting and paring: increase the area of heat exchanger and effectively transferring heat.
6. Faceplates are designed hooking type and easy for assembling and maintenance.
8. Antisepsis technique: dirt avoidance and supply clean water.
9 Surface treatment with anti-bask and transfer-color resistant powder, keep the original color for a long time.
10. A condenser is optional for gas-fired boiler. It is possible to save 12% fuel and decrease noise 20~30dB.
11.Applicable fuels: gas,oil,dual fuel.

Applications:
1. Providing heating for air-conditioning system and hygienic hot water.
2. Built-in heat exchanger can be designed to type of bi-coil pipe, providing hot water with two different usages in the same time.
3. The built in heat exchanger can be designed according to different pressure requirement.
