Wood gasifying boiler ATTACK SLX 55 kW
Wood Gasifying Boiler ATTACK SLX
The ATTACK SLX 7000 series wood boiler is a professional solution for the most demanding customers who require the highest quality in heating and efficiency. It's designed for burning wood, making the boiler very user-friendly. The gasifying boiler is eco-friendly, offering high-quality construction and excellent efficiency. The larger loading space saves time needed for continuous refueling. Heating with the SLX boiler ensures high comfort and long lifespan. This boiler is a versatile solution providing efficient biomass combustion. Additionally, the ATTACK SLX gasifying boiler is equipped with a choice between two control systems: PROFI control and LAMBDA control. We've equipped the ATTACK SLX with a loading chamber with above-standard dimensions. With the LAMBDA Touch version, it's possible to connect the boiler to the internet and control it remotely using a mobile phone.
Warranty for ATTACK boilers:
- 24 months
- 36 months if installed with a buffer tank and Laddomat charging unit
Long Burning Time
With full utilization of the loading chamber, the fuel in the boiler will burn continuously for 8-12 hours. Pieces of wood with a length of 1.2 meters only need to be cut in half once to fit into the extended loading chamber, allowing for significantly larger wood pieces to be loaded.
Wood Boiler and Its Quality of Construction
We've developed the boiler with a precise emphasis on construction quality. It was important to choose the right materials and technological procedures to ensure the boiler's resistance to various influences. The boiler's long lifespan is guaranteed by 6 mm thick boiler steel. Reliable performance is also provided by a high-quality refractory concrete nozzle that can withstand temperatures up to 1350°C.
Modern Technologies and High Efficiency
The ATTACK SLX is equipped with a high-efficiency tubular heat exchanger with turbulators, which contribute to the boiler's high efficiency. Additionally, the turbulators ensure a clean heat exchanger in the SLX LAMBDA Touch version. The boiler is also equipped with protection against tar emissions, which is maintained by a dry jacket placed around the entire loading chamber.
Enhanced Boiler Comfort and Control Options
The wood gasifying boiler SLX is equipped with: PROFI or LAMBDA Touch control. Boiler control is very simple and intuitive, with many functions being automated. It features automatic shutdown after fuel burning, automatic cleaning, control of heating pumps and accumulator tank charging, and even computer or smartphone-based heating control. To achieve greater boiler power, we recommend purchasing an accumulator tank along with a mixing device like Laddomat.
PROFI Boiler Regulation
If there's a need to control multiple devices, consider the boiler with PROFI control. The PROFI control uses a more precise PID regulator, allowing for more efficient parameter adjustment. This leads to a more precise and smooth regulation of fan rotations, consequently improving control of flue gas temperatures and overall boiler performance. In addition to PID regulation, the Fuzzy Logic technology contributes to better combustion efficiency. It utilizes sensors to monitor combustion and adjusts the process in real-time to optimize efficiency. The PROFI regulation system can handle complex heating systems. It allows control of accumulator tank charging pump, domestic hot water, or heating circulation pump. This system also controls the accumulator tank and prevents its discharge, shutting down the boiler if fuel is depleted. PROFI regulation is straightforward and intuitive. The display shows all necessary operational information (boiler temperature, flue gas temperature, accumulator tank temperature) and the current status of individual components (fan operation, charging pump for domestic hot water / accumulator tank, circulation pump operation).
PROFI Regulation Features
- Suitable for everyday heating
- PID Controller - more precise and smooth fan speed regulation
- Fuzzy Logic control sensors
- Controls 2 pumps (heating circulation pump + accumulator tank charging pump or DHW)
- For systems with an accumulator tank - built-in logic for charging and protection against tank discharge
- Easy operation and display showing current operational information (boiler temperature, flue gas temperature, accumulator tank temperature)
- Parameter monitoring (fan operation, DHW/accumulator tank charging pump operation, circulation pump operation)
- Control of circulation pump via thermostat
- Automatic boiler shutdown after fuel burning
- Manual adjustment of primary and secondary air
LAMBDA Boiler Regulation
To achieve even better efficiency, power, and user comfort, you can use Lambda control. This control utilizes a Lambda probe for more precise combustion regulation. Measurements obtained from the probe are evaluated, and based on them, servomotors control the amount of primary and secondary air supplied. This technology optimizes the combustion mixture, resulting in higher efficiency compared to PROFI control. Achieving greater efficiency also leads to lower measured emission values, which better protect the environment. With more precise combustion process control using Lambda regulation, the boiler can ignite faster, as it can gasify fuel for up to 12 hours, saving your time. More efficient combustion significantly contributes to the boiler's longer lifespan. All combustion operational parameters are displayed on a clear LCD screen. Parameter adjustments can be made using the boiler control panel. With Lambda control, you achieve high-quality control with improved combustion values and higher efficiency.
LAMBDA Regulation Features
- 7-inch touchscreen display
- Internet connection - control via computer and smartphone
- Easy setup and troubleshooting diagnostics
- Possibility of remote system updates
