Despite being designed for high consumption, it achieves high performance with tight consumption. Thus achieving energy and economic savings, all thanks to the fact that it incorporates GreenTech technology along with other features, such as EC forced draft fans.

The ECO-HK range includes the Hargassner ECO-RA collector. With a performance of more than 90%, it achieves significant energy savings, among others, thanks to a low driving power of the silo auger (only 0.18 kW) and the highly efficient and robust flat pinion gear. Savings of up to 67% can be achieved, compared to other conventional augers.

With its stepped crushing grill, it prevents the formation of crusts. It is made up of two grills located next to each other (three from 150 kW), with independent movement that allows the bed of embers to be kept uniform during combustion and to ensure proper cleaning of the grills. The smoke recirculation system included as standard will also have an impact on avoiding the formation of scabs.

Thanks to its ember monitoring system, it allows you to achieve the most efficient combustion state depending on the quality of the fuel. The boiler always operates with the required power and at the optimal combustion values.

As accessories, an integrated return temperature increase and an ash aspiration system with a 300-liter capacity tank are available as options.
