EKO-KWRW: 40, 50, 60, 70
characteristics
KWRW boiler with water grate, air fan and microprocessor control allows the burning of hard coal, coal dust and biomass of different granulation. The nozzles built in the shell of the exchanger evenly aerate the entire fuel stack.
Boiler advantages:
- high combustion efficiency,
- low operating costs,
- simple attendance and maintenance,
- high-quality control and safety devices,
- rapid assembly during installation of the boiler in the boiler room.
The boiler is equipped with driver EL880 zPID
