Ecological and fully automatic pellet boilers ATMOS
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, 500 or 1000 l). A part of the boiler room can be used for storing pellets before conveying into burner.
Burner operates fully automatic. 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.
Make sure to choose "Feeding screw" from "Available options" before putting product to the cart.

Pellet burner ATMOS A25
Specified fuel: good quality pellets with 6 – 8 mm diameter, 5 - 25 mm lenght and 16 - 19 MJ.kg-1 caloric power (white pellets).
The burner screen: used to display the current status of the burner and adjusting her functions
Burner control: with an AC07X (AC07) electronic control unit that controls the operation of the external conveyor, two ignition spirals and the fan in accordance with requirements of the boiler and the heating system. The electronic system is protected with the safety thermostat of the boiler, safety thermostat at the pellet supply to the burner, the fan speed transducer and the flame sensing photocell. The operation of the burner is indicated on the electronic control display.
Fuel feeding: with an external auger conveyor controlled from electronic regulation of burner.
Basic functions of burner:
The possibility of using two spare outputs R and R2 for various applications
The possibility of the involvement of four different sensors TS, TV, TK a TSV
TS - sensor on the tank bottom
TV - sensor on the tank top
TK - boiler sensor or middle sensor on the tank
TSV - flue gas sensor or solar panel sensor
- burner controlling it in accordance with two temperatures (sensors) on the buffer tank
- control of boiler fan from burner with the help of the auxiliary output
- control of boiler pump from burner with the help of the auxiliary output
- control of the solar system directly from the burner
