Equithermal controller ATMOS ACD01Wood Pellet Burner Gasification Boilers
- DC18S
DC18S, DC25S, DC24RS, DC30RS
are designed for burning wood and wood briquettes
C18S a AC25S
are designed for burning wood and coal
on the principle of generator gasification with the use of a gas exhaust fan (S), which withdraws the combustion gases from the boiler.
The boiler body, made as a weldment of quality 3 to 8 mm steel sheets, comprises:
- Fuel hopper (6 mm), which is equipped with a door having an opening for mounting the pellet burner in the upper section, and with a gasification nozzle or with a rotary iron gasification grate for easy ash removal at the bottom;
- Burnout part, which is equipped with ceramic pipe fittings for ideal burnup of all the combustible substances with a high efficiency and environmentally-friendly combustion.

The fuel hopper top stoking door is modified for installation on an ATMOS A25 burner.
- A25 burner
ATMOS A25
The ATMOS A25 burner is designed for burning quality white pellets made of soft bark-less wood with a diameter of 6 to 8 mm, length of 10 to 25 mm and the calorific value of 17 to 19 MJ/kg. Automatic fuel ignition by means of a glowing filament which ignites the pellets whenever heating-up is required, is an advantage of these burners. Thus, the burner and the boiler work at full power with maximum efficiency and the best combustion quality. Unlike a number of competition products that do not have any ignition device and must maintain a glowing layer in the combustion space. Thus, they are operated at low power when the temperature of combustion gases drops below 100°C. Therefore, tar and acids are generated in the combustion space which reduces the service life of the boiler, lowers efficiency, increases fuel consumption, decreases combustion quality, and further fouls the boiler which requires more frequent cleaning.
The following conveyors are designed for the ATMOS A25 burner:
- A screw conveyor for the ATMOS A25 model DA2000 with the length of 2 metres and diameter of 80 mm
- A screw conveyor for the ATMOS A25 model DA2500 with the length of 2.5 metres and diameter of 80 mm
- C18S and AC18S
Burner Standard Boiler Build-In Benefits
- A simple and affordable solution
- Comfort possibility of burning large pieces of wood or pellets without manual stoking
- Easy wood, briquettes, or coal stoking with no smoke removed by an exhaust fan = a clean boiler room
- Large (500 and 1,000 liter) pellets hopper (boiler room section) = refueling once in 7 and 14 days (once a year)
- Comfortable and dust-free ash removal with an exhaust fan once in 14 up to 30 days
- Automatic ignition of pellets with the ignition filament already built-in the burner
- High efficiency (83 up to 91%) by fuel and boiler type = high saving of heating costs
- Environmentally-friendly combustion = boiler according to ČSN EN 303-5 Class 3 = subsidized from the "Green to Savings" program of the Czech State Fund for the Environment (SFP) (except for C182 and AC25S due to the possibility of coal burning)
- Overheating protection cooling loop = no risk of boiler damage
- Automatic boiler turn-off with a combustion gas thermostat after the fuel has burnt out completely
- Small dimensions and modern design
Installation
When installing the burner into the upper door of the gasification boiler, it is necessary to use a conveyor with a minimum length of 2 meters so that the length of the hose between the conveyor and the burner is ma inimum of 15 centimeters for safety reasons. However, the optimum hose length is approximately 40 cm so that the door to the pellet burner is easy to open when cleaning the combustion chamber.

Recommended connection
We recommend a configuration with LADDOMAT 21 or a thermoregulation valve and a compensating tank with a capacity of 500 or 1,000 litres for achieving low fuel consumption and a high service life of the burner and the boiler. Use a specially designed control unit ATMOS ACD01 or the AS25 set, which is used for special functions of the burner ATMOS A25 to further reduce fuel consumption (up to 20 %) and ensure correct operation of feeding the compensation tank.

Connection of the boiler with the A25 burner and electronic regulation ACD01
The boilers DC18S, DC25S, DC24RS, DC30RS with pallet burner ATMOS A25 are included in the grant project "Zelená úsporám". Therefore, it is possible to order these boilers directly from the manufacturer in the left-hand or right-hand version with the pellets burner built-in modification already available. In case you would wish to install the burner into the standard or other ATMOS boiler, you could order a special set for its rebuilding allowing the installation of the pellet burner into the upper door. The set consists of the complete modified door, special electric wiring, and accessories with 23 items.
