Combined boiler ATTACK DPX COMBI PELLET 40
ATTACK DPX COMBI PELLET Combined Boiler
The ATTACK DPX COMBI PELLET boiler is a multifunctional combined boiler from the 6000 series, designed for wood and pellet combustion. This boiler offers the convenience of burning both wood and pellets, making it extremely user-friendly. To optimize the combustion process, the fully automatic Pellet Burner Automatic has been incorporated, ensuring convenient and fully automated pellet combustion with all the features of the DPX boiler with PROFI control. The built-in pellet burner allows you to enjoy pellet combustion, providing you with the comfort and advantages of a pellet boiler.
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 system will be elevated to a higher level. The burner effortlessly handles most tasks, including automatic grate cleaning, start and end of combustion. Its operation can be easily controlled from a warm room using a thermostat, without the need to visit the boiler room.
Spacious Loading Chamber
The loading chamber of this boiler model is very large and based on the ATTACK DPX model. A larger chamber extends the heating time per fuel load and allows for a larger wood load.
Easy Fuel Type Change
Changing the fuel type in the DPX Combi Pellet boiler is designed to simplify the process and optimize the time required. Converting from a gasifying boiler to a pellet boiler is straightforward and does not require significant physical effort. The fully automatic pellet burner is mounted on a position-adjustable pantograph, making it easy to insert through the top door of the boiler and use pellets as fuel. One of the great advantages of this boiler is the combination of affordable and eco-friendly heat obtained from wood gasification and the comfort provided by a fully automatic pellet burner.
High Efficiency
The DPX Combi Pellet boiler is developed with a focus on high quality and efficiency. By using movable turbulators, the boiler achieves excellent heating parameters. Gasification is controlled by a closely monitored technology similar to the DPX boiler. The boiler control is simple and intuitive, utilizing only the PROFI control in this model. To increase the boiler's power, we recommend purchasing an accumulator tank together with the ATTACK Oventrop mixing device.
PROFI Boiler Control
If you need to control multiple devices, consider opting for a boiler with PROFI control. The PROFI control uses a more precise PID regulator, allowing for more efficient parameter regulation. This results in a more precise and smooth fan speed regulation, leading to better control of exhaust 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 for optimization. The PROFI control system handles complex heating systems. It can control the circulation pump of the accumulator tank, domestic hot water, or heating circulation pump. This system also maintains the accumulator tank's charge and shuts down the boiler when fuel is depleted.
PROFI Control Features
- Suitable for daily heating
- PID regulator for more precise and smooth fan speed regulation
- Fuzzy Logic control sensors
- Controls 2 pumps (heating circulation pump + accumulator tank charging pump or domestic hot water)
- For systems with accumulator tank - built-in logic for charging and protection against discharge
- Simple operation and display of current operational information (boiler temperature, exhaust temperature, accumulator tank temperature)
- Monitoring of parameters (fan operation, domestic hot water/accumulator tank charging pump operation, circulation pump operation)
- Heating circulation pump control via thermostat
- Automatic boiler shutdown after fuel combustion
- Manual adjustment of primary and secondary air
