Wood boilers ATMOS Generator DC15GS, DC20GS, DC25GS, DC32GS and DC40GS with a large application space lined with ceramics for optimal combustion quality. It’s a real wood gas generator.

Advantages of gasification boilers for piece wood ATMOS

• Option to burn large pieces of wood 
• Large space for wood – long burning time – up to 12 hours, depending on boiler type
• High efficiency 88,8 to 91,2 % depending on the type – primary and secondary air is preheated to a high temperature
• Ceramic loading chamber – fuel pre-drying
• Ceramic combustion chamber
• Ecological combustion – boiler according to EN 303-5:2012 class 5, EKODESIGN 2015/1189
• Exhaust fan – dust-free ash removal, smokeless boiler room
• Cooling loop against overheating – without the risk of damaging the boiler
• Automatic shutdown of the boiler after the fuel burns out – flue gas thermostat
• Convenient ash removal – large space for ash (when burning wood, clean it 1x / week)
• Boiler without tubesheet – easier cleaning
• Small size and low weight
• Possibility of choosing a door R / L (right/left) for selected types
• Possibility of connection without accumulation tank
• High Quality

Installation

ATMOS boilers must be connected via the LADDOMAT 22 or ESBE thermoregulation valve (three-way valve controlled by actuator in case of using electronic regulation ATMOS ACD 03/04) to achieve keeping the minimum temperature of water returning to boiler at 65 °C. We keep the outlet temperature of the boiler in the range of 80 – 90 °C and set the temperature of the water to the radiators or floor heating on the mixing three-way valve as needed (e.g. 30 – 80 °C). The default configuration of all boilers includes a cooling circuit to prevent overheating. We recommend installing a boiler with accumulation tanks, which will reduce fuel consumption and increase heating comfort.

Boilers regulation

Electromechanical regulation – boiler performance is regulated by an air regulating valve controlled by a draft regulator, FR 124 type, which automatically opens or closes the air valve according to the set water outlet temperature (80 – 90 °C). In addition to performance regulation, the draft regulator helps protect the boiler against overheating. Its advantage is a quick ignition and firing up to the required output when the air valve is fully open. The boilers are equipped with a control thermostat on the instrument panel, which controls the exhaust fan according to the set water outlet temperature (80 – 85 °C) and a flue gas thermostat, which is used to shut down the boiler and turn off the exhaust fan after the fuel has burned out. In the case of connecting a boiler with accumulation tanks, the flue gas thermostat also controls the operation of the pump in the boiler circuit.

The advantage of regulation and design of ATMOS boilers is that the boilers work with a good chimney draft up to 70 % of the nominal power even without a fan.

Panel composition:
Main off switch, safety thermostat, thermometer, regulator thermostat and combustion thermostat

Electro-mechanical regulation is an optimal solution for easy management of the operation of the boiler (ventilator). The design of the panel with standard regulation is a basic design for all produced boilers.

Equithermal regulation ACD 03

Each boiler can be equipped with a modern touch electronic control ATMOS ACD 03 for controlling the entire heating system depending on the outdoor temperature, room temperature and time. This regulation is able to control the boiler itself with a fan with many other functions.

Equithermal regulation ACD 04

The boilers DC25GS, DC32GS can be ordered from the factory with built-in ATMOS ACD 04  touch screen control.The boilers are allready equipped with all necessary sensors.This unit is designed for comfortable control of the hot water system of the heated building. The controller contains functions for direct control of the boiler, boiler circuit, three heating circuits, domestic hot water, solar, etc.

Automatic wood ignition

The automatic ignition of wood is used for planned ignition of the boiler, e.g. before coming home in the afternoon or before arriving at the cottage. The ignition of the fuel is very fast (approx. 5 minutes) and allows the operator to arrive “into the heat”. Fuel ignition can be set and scheduled to control ATMOS ACD 04 according to time (weekly program), according to the requirements of the heating system or according to the temperature in the accumulation tank. Automatic wood ignition is intended for the DC40GS boiler.

A device for automatic wood ignition is built in between the upper and lower doors (a chamber with a heating spiral). High-quality wood pellets are used for ignition, which are used to fill the ignition chamber. The amount of pellets corresponds to the size of the shovel that is included in the delivery of the boiler.
The pellets are ignited at the set moment using an electric heating spiral (500 W).
