Wood gasification boiler ROJEK PK BIO 40

Toploader wood gasifier ROJEK PK BIO for firewood and solid fuels

The ROJEK PK BIO wood gasifier represents the latest generation of modern heating technology. This innovative device is manufactured in the Czech Republic and meets all relevant standards and legal requirements for operation in Germany, including the requirements of the Federal Immission Control Ordinance (BImSchV2).

The outstanding feature of this ROJEK wood gasification boiler is its top-mounted loading opening, which allows for particularly convenient and easy filling of the boiler from above. This design allows for the easy addition of various solid fuels such as logs, loose material, wood chips, or garden waste. The maximum log length is 530 mm, allowing for a high degree of flexibility in fuel selection and loading.

With its generous combustion chamber volume, the ROJEK PK BIO wood gasifier is ideal for single-family homes, workshops, farms, families with large gardens, and all applications where simple and efficient handling of solid fuels is paramount.

The combustion of various suitable fuels, including wood with a moisture content of up to 20%, does not affect the warranty conditions. Therefore, the exclusive use of kiln-dried wood is not required. Users benefit from a flexible and reliable solution.
