Wood gasifying boiler ATTACK SLX
The wood gasifying boilers ATTACK SLX are intended for economical and ecological heating of dwelling houses, cottages, small plants, work rooms and similar objects. Prescribed fuel for SPX boilers is dry wood. The volume of the SLX boiler´s feeding chamber is unique and ensures longer burning on fuel load. This unique chamber also makes possible to load big wood logs and enables to load the wood logs of half-meter, which saves time by chopping the wood.
The volume of the SLX boiler´s feeding chamber is unique: 200 – 230 l and ensures longer burning on fuel load. This unique chamber also makes possible to load big wood logs – length of the feeding chamber is 690 and 790 mm and enables to load the wood logs of half-meter, which saves time by chopping the wood.
From technical view it is a boiler line with high efficiency, low flue gas temperature and more effective combustion process. Achieved efficiency of the ATTACK SLX boiler is up to 92 %. By installation of more efficient boiler of the ATTACK SLX line it comes to significant decrease of the operating costs, projected into the fuel savings, in comparison with less efficient boilers that combust same fuel.
From the social-wide view, it is an enviroment-friendly source, combusting wooden biomass, which is a kind of CO2-neutral fuel. Considering the harmful emissions, the average concentration of CO value in the flue gas, is during operation of the LAMBDA version under the level of 200 mg/m3 related to 10 % of O2. Under the valid European norm EN303-5, classifying the solid fuel boilers by efficiency and emissions to individual classes, the ATTACK SLX boiler (version LAMBDA) reaches 25 times lower concentration of harmful CO emisions in the flue gas incomparison with the allowed level of this norm!
The ATTACK PROFI of the „PID“ generation is a kind of the advanced regulator, which enables to modulate the heat output in the ATTACK® wood gasifying boilers by regulation of the fan rotations. The well-readable display shows the necessary information and makes the boiler control easier.
The ATTACK SLX PROFI boiler brings the improvement of the PID regulation to control the fan rotations according to the temperature of water and flue gas and thereby to achieve the optimal efficiency. The regulator uses the advanced Fuzzy logic system for control to regulate the wood gasification system in the optimal way – to ensure the lowest heat loss possible.
The boiler equipped with the regulator ATTACK PROFI „PID” can control the heating system equipped with the following items: a pump for charging the accumulation tank, accumulation tank, circuit pump of heating circuits and room thermostat, by the lowest loss of heat energy possible. The regulator can be connected and set in the way enabling to control the pump of heating circuits and pump to charge the tank for domestic hot water.

Regulation LAMBDA TOUCH
ATTACK SLX LAMBDA Touch electronics consists of the well-readable touch display for quick access to the necessary information and settings. Software of electronics can be anytime upgraded by the USB key. The boiler can be connected to internet by the LAN cable and controlled from the distant point, even by the Smartphone.
The boiler is designed with reference to the user comfort. Thereby is the exchanger cleaned automatically by motor and turbulators. The boiler electronics can be extended with additional external modules to control the heating mixing circuits, D.H.W. tank, solar panels or other automatic boiler ATTACK LAMBDA Touch.
