ROJEK PK BIO 40 wood gasification boiler

ROJEK PK BIO top-loading wood gasifier for firewood and solid fuels

The ROJEK PK BIO wood gasifier represents the latest generation of modern heating technology. This innovative appliance is manufactured in the Czech Republic and meets all relevant standards and legal requirements for operation in Germany, including the requirements of 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 permits the trouble-free feeding of various solid fuels such as logs, bulk materials, 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, agricultural operations, families with larger gardens, and for all applications where the 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. This provides users with a flexible and reliable solution.
