The Pyrot is a state-of-the-art wood-fired boiler that achieves an exceptional efficiency of 94% thanks to its rotary combustion system and modulating control. Its clean combustion technology reduces CO, NOx, and fine dust emissions to a minimum. It is easy to maintain, available as a containerized solution, and guarantees safe and sustainable operation.

The funnel extraction system operates similarly to an agitator and ensures that the fuel—which is usually dry—flows out on its own. The effective diameter of the cone auger discharge system can range from 4 to 6 meters. It is particularly well-suited for round silo bases.

With the LogicPro V4, we are introducing a completely redesigned control system that sets new standards in user-friendliness, technological integration, and efficiency. This new generation has been specifically tailored to meet the high demands of modern biomass combustion plants—both technically and in terms of ease of use.
Three key aspects were central to the development of the LogicPro V4: modern design, maximum user-friendliness, and the
use of the latest web technology. This combination enables particularly intuitive operation and powerful control of the system. The result is an interface that provides all relevant information at a glance while flexibly adapting to individual requirements.
A key feature of the new user interface is the integration of HTML5 technology. This enables a platform-independent, high-performance, and future-proof display of all user content. Compared to traditional control interfaces, HTML5 offers numerous advantages:
Up to 900 kW nominal capacity and with a maximum moisture content of fuel of M 35, electric industrial hot air blowers are available for igniting the fuel in the crucible or on the moving grate.
Wood chips, residual wood, wood pellets, wood shavings
Permitted fuels:
150–500 kW:
500–540 kW:

The patented rotary combustion system of the PYROT boiler represents the state of the art. A feed screw continuously conveys the fuel onto a moving grate, where the fuel is subjected to gasification (under lambda-controlled primary air supply). Continuous gasification takes place under oxygen-deficient conditions. Rising combustion gases are mixed with atomized secondary air imparted with rotational momentum by a rotary blower. This ensures thorough mixing with the combustion gases.
The PYROT’s proven combustion technology achieves similar emission values to those of a modern gas-fired plant and, depending on the fuel, keeps
CO, NOx, and particulate emissions to a minimum. The combination of combustion technology and digital modulating output control enables
efficiencies of up to 94%.
The digital modulating output control ensures optimal combustion by precisely regulating the ratio of combustion air, recirculated
flue gas, and fuel. The control system monitors:
