Description
ATMOS AC is designed for burning coal and wood based on the principle of generator gasification using an exhaust fan (S), which draws flue gases from the boiler. The boiler body is made of high-grade steel sheet with a thickness of 3 to 6 mm. It consists of two chambers placed one above the other, the upper one serves as a fuel tank, the lower one as a combustion chamber and ash pan. Between them is a new, patent-protected rotating grate made of stainless steel, which enables gasification of burned fuel and easy ash removal.
In the rear part of the boiler body there is a vertical flue gas channel, in the upper part equipped with a valve for ignition. The upper part of the exhaust pipe is equipped with an exhaust nozzle for connection to the chimney. Primary and secondary air is heated to a high temperature to achieve high efficiency and combustion quality.
Advantages of ATMOS AC gasifying boilers for hard coal:
- Large fuel tank - long burning time
- High efficiency – primary and secondary air is heated to a high temperature
- Ecological combustion - boiler according to ČSN EN 303-5 class 5, EKODESIGN 2015/1189
- Exhaust fan - dust-free ash removal, smoke-free boiler room
- Cooling loop before overheating - no risk of boiler damage
- Automatic boiler shutdown after fuel is burned - flue gas thermostat
- Convenient ash removal
- Small size and light weight
- Choice of left / right doors
- High quality
Warranty:
- 3 years for a boiler installed with Laddomat or temperature valve TV and heat accumulation tank
- 2 years without heat accumulation tank and Laddomat
Primary fuel: hard coal
