Highlights / Advantages
⭐ 55 kW nominal output – designed for high heat demands
⭐ 180 liter loading chamber – long burn times of 5–9 hours
⭐ Top loading – convenient filling with logs
⭐ Electronic control – stable and optimized combustion control
⭐ EN 303-5 Class 5 & Ecodesign compliant – low emissions and standard-compliant
Application & Target Group
The ROJEK PK BIO 60 is intended for large residential buildings, apartment buildings, commercial applications, or agricultural operations.
Due to its high output, it is suitable for systems with higher heat demand and is recommended for efficient operation in combination with a sufficiently sized buffer tank.
Everyday Benefits
The large loading chamber volume of 180 liters enables longer burn times and reduces the number of reloading operations.
Top loading makes handling logs up to 530 mm in length easier. The heat exchanger can be cleaned via an externally located cleaning lever, which simplifies maintenance work.
