Wood gasifier ROJEK PK BIO 25 kW - Efficient boiler for firewood 🔥

Wood gasification boiler ROJEK PK BIO 25 KW

Toploader wood gasifier ROJEK PK BIO for firewood and solid fuels

The ROJEK PK BIO wood gasifier is a modern, state-of-the-art boiler, specially developed for convenient, efficient, and environmentally friendly heating with logs and other solid fuels. The boilers are manufactured in the Czech Republic and meet all technical and legal requirements for reliable and safe operation in Germany.

The outstanding feature of this ROJEK wood gasifier is the top-loading opening for fuel. Thanks to this top-loading design, fuel – whether logs, wood chips, bulk material, or garden waste – can be added quickly and easily from the top. A maximum log length of up to 530 mm can be accommodated. mm can be used, which means that even larger pieces of wood can be processed without any problems.

The ROJEK PK BIO boiler is ideal for heating single-family homes as well as for use in workshops, farms, or families with large gardens. Its design supports easy operation, especially when various wood fuels or waste wood need to be easily added.

Another advantage is that the combustion of different fuel types does not affect the warranty conditions of the ROJEK PK BIO. A maximum moisture content of 20 % required – dry wood is therefore not a prerequisite for trouble-free operation. The ROJEK wood gasifier offers flexibility in fuel selection without compromising on performance, safety, or manufacturer's warranty.

Advantages:

• The upper loading of the combustion chamber enables quick and convenient fuel supply via the hinged upper loading door.
• The large combustion chamber volume (PK BIO 20–30 kW = 130 l, PK BIO 40–60 kW = 180 l) allows longer heating intervals and larger fuel quantities.
• High efficiency at rated power ensures efficient combustion and energy yield.
• The ROJEK PK BIO boiler complies with current emission regulations according to BImSchV2 for Germany as well as the environmental standards in Austria and the EU.
• Maximum log length 530 mm is available for all power sizes (recommended wood moisture content maximum 20 %).
• Longer fuel burning time of 5 to 9 Hours at full load, depending on fuel quality and boiler output.
• Boilers of the ROJEK PK BIO 20 to PK BIO 60 model meet the class 5 for firewood according to EN 303-5. Furthermore, all models are ECODESIGN certified according to Regulation (EU) No. 2015/1189, which underscores their environmental compatibility.
• An advanced electronic control system ensures user-friendly operation; it regulates, among other things, the exhaust fan, the boiler water temperature including pump control, temperature ranges, various automatic modes, fuel burn-off time, heat-up function, fan speed, flue gas monitoring, safety functions, audible alarms, and language selection.
• The heat exchanger can be easily serviced from the outside using the operating lever and cleaning door (available as standard or left-hand version).
• A three-year leak-tightness guarantee is provided for the boiler body, which can be extended to five years if the boiler is operated with a buffer tank.

ST86 control unit for the ROJEK PK BIO wood gasifier:

• Control of the exhaust fan ensures optimal combustion and safe combustion.
• Monitoring and control of the boiler water temperature including automatic switching on and off of the circulation pump and switching off the fan.
• Individual setting of the desired minimum and maximum temperatures for maximum efficiency.
• Operation can be manual or fully automatic, with several variants of automatic operation depending on user preferences and operating situation.
• Display and adjustment of the fuel combustion time as well as a special function for the manual heating process.
• Continuously variable fan speed control allows fine-tuning to the desired heating operation.
• An integrated flue gas sensor, comprehensive protection for the boiler and controller, and a selection of different language options round off the convenient operation.
