ATTACK SLX COMBI PELLET Combination Boiler

The ATTACK SLX COMBI PELLET boiler is a multifunctional combination boiler from the 7000 series designed for wood and pellets. It is adapted for burning both wood and pellets, making the boiler very convenient to use. This model is based on the SLX model and can be converted exclusively into a wood boiler. To optimize the combustion process, a fully automatic Pellet Burner Automatic has been used, which ensures convenient and fully automatic pellet combustion and possesses all the advantages included in the base model of the SLX boiler with PROFI control. This boiler is a universal solution that provides automated and efficient biomass combustion, resulting in an efficiency of up to 91.6% for this boiler model. The boiler is additionally equipped with a burner on which you can adjust power, automatic ignition, afterburning, and cleaning.

Warranty for ATTACK boilers:

• 24 months
• 36 months if installed with a buffer tank and Laddomat charging unit

High Comfort

When using pellets with the fully automatic Pellet Burner Automatic, the comfort of your heating will be elevated to a higher level. The burner effortlessly handles most of the work, including automatic grate cleaning, ignition, and combustion termination. You can easily control its operation from a warm room through a thermostat, without the need to visit the boiler room.

Spacious Loading Chamber

The loading chamber of this boiler model has a capacity of up to 200 liters, based on the ATTACK SLX model. The oversized chamber extends the heating time per fuel load and allows for adding a larger amount of wood. If you choose to heat with this boiler using wood, you will save a lot of time on converting the boiler to this type of fuel and reduce the need for cutting wood into smaller pieces. Larger wood pieces not only save time but also prolong the combustion durability per fuel load.

Easy Fuel Switching

The fuel switch in the SLX Combi Pellet boiler has been designed to simplify this process as much as possible and optimize the time allocated to it. The conversion from a gasifying boiler to a pellet boiler is very simple and does not require much physical effort. The fully automatic pellet burner is mounted on a positionable pantograph, making it very easy to insert through the upper doors of the boiler and use pellets as fuel. A significant advantage of this boiler is the combination of inexpensive and environmentally friendly thermal energy obtained from wood gasification and the comfort provided by the fully automatic pellet burner.

High Efficiency

The SLX Combi Pellet boiler has been developed with a focus on high quality and high efficiency. With the use of movable turbulators, the boiler achieves excellent heating parameters. The boiler control is very simple and intuitive, utilizing only the PROFI control in this model. To achieve higher boiler power, we recommend purchasing an accumulation tank together with the Laddomat mixing device. The boiler features automatic shutdown after fuel burnout, automatic cleaning, control of heating pumps and accumulation tank charging, and even control of heating via a computer or smartphone.

PROFI Boiler Regulation

If there is a need for controlling a larger number of devices, it is worth considering a boiler with PROFI control. PROFI control utilizes a more precise PID regulator, allowing for more efficient parameter regulation. This results in a more precise and smooth control of the fan speed, thus improving the control of flue gas temperature and ultimately the boiler's final efficiency. In addition to PID regulation, the Fuzzy Logic technology contributes to better combustion efficiency. This technology uses sensors to monitor combustion and adjust the process in real-time to optimize performance. The PROFI regulation system enables the management of complex heating systems. It is possible to control the charging pump of the accumulation tank, domestic hot water, or heating circulation pump. The presented system also supports the accumulation tank and prevents its discharge by shutting down the boiler if there is no fuel in it.

PROFI Regulation Features

• Suitable for daily heating
• PID regulator - more precise and smooth fan speed regulation
• Fuzzy Logic control sensors
• Controls 2 pumps (heating circulation pump + accumulation tank charging pump or DHW)
• For systems with an accumulation tank - built-in logic for tank charging and protection against discharge
• Easy operation and display of current operational information (boiler temperature, flue gas temperature, accumulation tank temperature)
• Monitoring of parameters (fan operation, DHW/accumulation tank charging pump operation, heating circulation pump operation)
• Control of the heating circulation pump via a thermostat
• Automatic boiler shutdown after fuel burnout
• Manual adjustment of primary and secondary air
