Altherm C-Type Product family
chips burner 30-125 kW 

Due to the auger-feeding system of the burner it can be fed with several size and type of fuels, from the wood pellet, through the minced herbaceous plants until the rough wood-chips. Due to the boiler’s construction it is available to burn log and round log. Due to the connected large daily container, the boiler does not require constant supervision (optional sizing). The burner can easily be put into the aperture, then the fan insures the combustion’s air demand after ignition, based on data of the built-in pipe-thermostat. The mechanical sensor situated in the burner directs the movement of the auger, thus the refill of the fuel, too. In case of the daily container’s exhaustion the dosing stops, an optional GSM-module, or a sounder device warns to the exhaust of the fuel.
This system is especially suitable for heating family houses with hot water system and production halls.
