Pelltech PK 500 - Pelltech Burners

Base Features Specification Documentation

High efficiency
PK250-PK1000 pellet boilers have efficiency up to 94% when converting pellets into heat.
Automatic cleaning
Automatic cleaning of all three passes will extend the maintenance intervals significantly.

Smart connect
Remote control of the boiler via Boiler control unit (available as an option) gives you possibility to keep an eye on burners work through computer or smartphone. It enables to control boilers work, data logging and to get notifications in case of any faults.
Clean energy
With the possibility of integrating ash cyclone with the boiler, lowest flue gas emissions can be assured.
