BIO SLIM – compact pellet boiler for small installation spaces and for high expectations of efficiency.
For high efficiencies A tube heat exchanger with swirlers ensures this.
The pellet hopper is located directly above the heat exchanger. This solution allows the installation of the pellet boiler in very small rooms.
Powerful and efficient pellet burner with automatic cleaning.
The tube heat exchanger with integrated turbulators ensures maximum energy yield and high boiler efficiency.
Powerful induced draft fan for the necessary negative pressure in the boiler and stabilization of combustion.
Intuitive and very simple operation of the boiler thanks to the modern APC 3 control system with touchscreen, which controls 6 pumps and two heating circuit mixers and is equipped with a factory-installed internet module.
Level sensor in the pellet container to indicate the fuel reserve and to interrupt operation so that the conveyor screw does not run empty.
