TIS HARD BIO 150 is a modern boiler with a maximum heating output of 300 kW with automatic fuel supply for burning wood chips. The boiler is designed to operate in heating systems for residential and industrial facilities. Distinctive a feature of the boiler is the ability to operate on wood waste fuel of any quality. The boiler is completed with a feed hopper device and automation.

System safety (thermal water protection with sensor fuel line temperature control) protects the boiler from fuel ignition in the system auto-feed. Due to the design features boiler and unique manufacturing technologies maximum possible recovery is achieved by the thermal energy of the combusted fuel. The exhaust gas temperature is not more than 155 °С.

An automatic ash removal screw system is an option also.
