ATMOS D 50 P

Product detailed description

- 13.5-45 kW ecological, fully automatic boiler for pellets only

- is designed for perfect combustion of pellets in such a way that a pellet burner is built into the left or right side of the boiler, according to customer needs, which fully automatically draws pellets from the storage tank using a screw conveyor. The fuel storage tank is usually placed next to the boiler or in an adjacent room and can be of any size (standard 250, 500 or 1000L). Often a part of the boiler room is used as the fuel storage, which is then sufficient for the entire heating season.

The operation of the pellet burner itself is completely automatic. When the burner receives a start command or when heating is needed, the conveyor feeds pellets into the burner nozzle and ignites them itself using a heating element (spiral). After the pellets have sufficiently ignited, the burner runs at the set output, which it maintains until the system (house) is heated. Then the burner switches off and the pellets in the burner chamber burn out completely. The burner is thus ready for a new start. The whole cycle repeats whenever heating is needed again.

The boiler output and other burner functions are controlled by an electronic control unit, which allows the boiler operation to be adapted to the specific conditions of the whole system. Refilling pellets, cleaning the burner's combustion chamber and removing ash is done once every 1 – 30 days, depending on the pellet quality and the size of the storage tank.
If needed, the boilers can be equipped with an automatic ash removal system for comfortable heating with minimal maintenance.

Accessories required for the boiler:
A45 burner	DRA50 screw conveyor - various lengths	pellet tank - various

Frequently Asked Questions

• How to choose the right output for a solid fuel boiler? Base your choice on the calculated heat loss of the heated building; however, with wood/coal boilers also consider that the boiler burns for several hours at essentially constant output during a single filling - it is therefore common practice to supplement the boiler with a buffer tank, which stores excess heat for later use instead of the boiler having to be inefficiently throttled down.
• What else do I need to install this boiler? Besides the boiler itself, the system usually requires: a buffer (equalizing) tank of adequate volume, a circulation pump (often already with a built-in Laddomat or thermoregulatory valve against low-temperature boiler corrosion), a safety valve, an expansion tank and a flue/chimney with sufficient draft corresponding to the boiler output - exact draft values can be found in the technical parameters above.
• What fuel is suitable and what is not? Use only the fuel recommended by the manufacturer for the given model (typically split logs of a defined length and moisture content, or possibly brown coal briquettes or coal depending on the boiler type) - unsuitable or too moist fuel reduces efficiency, increases tar and deposit formation, and can damage the boiler.
• What about chimney inspection and legislation? Before putting the boiler into operation, as well as regularly during its use (usually once a year for solid fuels), a chimney inspection/cleaning by an authorized chimney sweep is required by law - without the relevant inspection certificate, an insurance claim in the event of a fire may also be disputed.
• How much maintenance does the boiler require? This normally includes regular removal of ash and cleaning of heating surfaces/flue gas passages from soot (interval depends on usage intensity, usually every few weeks), and once a year a thorough inspection including seals and the chimney.
• Can I install the boiler myself? The actual placement and connection of the boiler to the heating system, chimney and safety elements should be carried out or at least professionally inspected by a heating technician - this is a device with an open flame, high temperatures and pressure components, where a connection error can be a safety risk.
