WOODCHIP HEATING SYSTEM WITH STEP GRATE TECHNOLOGY
Our Powerchip heating systems, with step grate technology, effectively combine maximum economy and minimum emissions. Subject to approval and model, these boilers can also be converted to alternative fuels, such as pellets, miscanthus and plant matter.
Summary of test assessments:
"exceptionally high level of efficiency and fuel flexibility thanks to unique industrial step grate technology (even in the lower output range); minimum power consumption and highest operational reliability result from a clever discharge concept; ..."

Highly efficient combustion
The woodchips are gasified on the step grate, where primary air is supplied, at an ember bed temperature of around 850 °C. The amount of combustion air and fuel charge is regulated by means of a lambda probe, so that the system achieves a level of efficiency of up to 94 %. With the aid of secondary air, the generated combustion gases are cleanly and efficiently converted into energy in a large rotating combustion zone.
low power consumption
The pioneering discharge system operates with slow turning motors that consume very little power and develop extremely high torque of up to 1200 Nm. In addition, the progressive screw conveyor incline and the optimised trough geometry ensure the highest operational reliability.
Advanced touchscreen controller
Operating POWERCHIP heating systems is particularly easy thanks to the well thought-out and user friendly touchscreen interface. All settings and scans of system data can be made in just a few steps.
HIGHEST CLEANING CONVENIENCE
An ash screw conveyor transports the ash from the self-cleaning step grate into an especially large moveable ash box. Dust from the automatic heat exchanger cleaning process is also continuously moved into a separate, easy-to-empty container. The optional automatic vacuum ash discharge into a 200 litre drum is highly convenient.
In order to ensure that our appliances meet our high quality aspirations and those of our demanding customers, we manufacture them completely and exclusively using the best possible materials in our ultra-modern Austrian factory.
It's all a matter of technology
Industrial step grate technology
POWERCHIP systems operate with a self-cleaning step grate which is generally only found in larger plants. This enables the ember bed height and boiler output to be adjusted in line with demand and fuel, without risking slag forming inside the boiler. The moving step grate keeps the primary air slots clean, ensures optimum combustion and also that ash is correctly discharged.
High grade components
In order to prevent unpleasant surprises, POWERCHIP boilers are made exclusively using the highest grade components. The robust version of the agitator motors and screw conveyor discharge, the reliable motors and gear units and the resilient silicon combustion chamber with step grate technology are but a few examples of this.
The optional pioneering control app from Guntamatic lets you regulate your heating system at any time and from anywhere. The intuitive user prompts and the touch/swipe controls allow you to call up and adjust temperatures and heating programs with a smartphone. Furthermore, the app keeps you informed of the current status of your heating system and offers various forms of analysis.

Woodchips cost around half as much as oil. Furthermore, they are also an ecologically sound choice, as heating is provided in a way that is neutral to our climate, as only the same amount of CO2 is released by burning as was absorbed by the tree whilst it was growing. That is good for the environment – and good for our children.
