The huge efficiency from about 90% belongs to the central signs of the LIGNOTHERM series. Clean combustion, even for difficult fuels, with the targeted addition of pre-heated secondary air or vortex air ensures complete combustion at high temperature. This falls well below the TA-Luft (Technical Guidelines on Air Quality Control) values, so future requirements for operators of NESTRO plants do not pose a problem. The quadruple-shell structure leads to extremely low radiation losses by medium-sized boilers.
Lignotherm - intelligent and adaptable

Convenient fully-automatic operation thanks to the optional microprocessor control with remote diagnostic capabilities and an interface to facility management highlights the market leadership of state-of-the-art technology. It can also be perfectly adapted to existing systems and ambient conditions.
Fröling boilers satisfy the highest requirements of modern heating systems as well as the applicable admission requirements.
