ATMOS D 21 P/19.5kw without fan

Boilers are designed in such a way that the burner is built into the left or right side of the boiler, functioning as a heat exchanger, which draws pellets from the storage tank by means of a screw conveyor. The fuel tank is located next to the boiler or in an adjacent room and can be of any arbitrary size (the standard size is 250 or 500 l). A part of the boiler room can be used for storing pellets before conveying into burner.

The burner itself operates as follows. If the burner is triggered (the need to heat arises), the conveyor gets pellets into the burners spout and ignites them using a glowing coil. Following sufficient pellet combustion, the burner is adjusted to the set output where it remains until the system is heated. Thereafter, the burner is switched off and pellets in the burners chamber are burnt out. The whole cycle is repeated again when heating is required.

The boiler output and other burner functions are controlled electronically, which enables an adaptation of the boiler operation to specific system conditions. Addition of fuel, cleaning of the burner combustion chamber and removal of ash is performed once every 1 - 14 days, depending on the quality of pellets. You can add to the boiler automatic ash remover which assures even more comfortable operating.

In price not include burner, pellets container and pellet feed.
