WOOD CHIP and shavings heating system


750 – 1.500 kW

Wood chip and shavings heating system


Froling‘s Lambdamat is a unique, fully automatic heating system for burning wood chips, shavings and pellets. It not only offers innovative combustion technology, but also a high level of convenience and operational reliability. The boiler sizes in the “Communal” version are suited to fuels with a water content of up to 50%.

Thanks to the special combustion chamber shape, Froling’s Lambdamat is perfect for burning fuels of different qualities and with a high bark content. The hydraulic moving grate continuously transports the fuel through the combustion chamber, ensuring that even heavy fuels are completely burned. In addition to fuel loading by feed screws, this boiler technology can also be supplied with a hydraulic feed system.
