Fröling Turbomatic 35 wood chip and pellet boiler

Fröling – premium Austrian boiler technology

Founded in 1961, the premium Austrian manufacturer Fröling specializes in log wood, pellet, and wood chip heating. The Turbomatic family combines automated combustion with adjustable heat generation.

Turbomatic TMC 35 – automated biomass heating

35 kW wood chip and pellet boiler for hydronic central heating systems. The model featured in the catalog was manufactured in 2005.

Main advantages

• Moving, vibrating, and tilting grate: The self-driven grate loosens the burning fuel, removes accumulated residue, and helps keep the combustion air path clean.
• Lambda control: The lambda probe continuously measures the oxygen content of the flue gas; the control unit adjusts the air supply accordingly when the fuel or its moisture content changes.
• Separate primary and secondary air: Primary air assists the combustion of the fuel bed, while secondary air assists the burnout of the released combustible gases.
• Automatic WOS heat exchanger cleaning: Turbulators moved in the heat exchanger tubes remove deposits and improve the transfer of flue gas heat to the heating water.
• Automatic combustion chamber ash removal: The system transfers the ash from the combustion chamber into the ash pan, requiring less manual ash removal for daily operation.
• Firebrick-lined combustion chamber: The heat-resistant lining maintains a high combustion temperature, and the large afterburning chamber gives more time for combustible gases to burn out.
• Controlled flue gas extraction: The exhaust fan ensures the flow of flue gas and supports uniform combustion.
• Independent drives: Feeding, the grate, and other units can be operated separately; the control system adjusts individual tasks to boiler operation.
• Wood chips, wood pellets, and wood shavings: The Turbomatic is designed for various wood-based fuels, so with proper feeding, it can also be adapted to locally available wood material.
• Log wood emergency operation option: The factory design also allows the use of log wood with a separately insertable grate.
• Automatic ignition: The built-in ignition unit ignites the fuel during the control startup process.
• Automatic auger feeding: The feed auger delivers the chips or pellets to the combustion point, adjusted to the boiler load.
• Backfire protection: The fuel supply route is separated from the boiler by a safety damper or rotary valve belonging to the design.
