Description

The largest Hercules.

The Werstahl Hercules HS320 to HS520 are automatic multi-fuel solid fuel boilers from 372 to 605 kW. They burn olive pits, kernels, pellets, nut shells, coal and bark, and with the special grate wood too, loaded by hand. With the matching burner they also run on oil, LPG or natural gas.

The fuel reaches the burner through an auger driven by a geared motor, and a fan with adjustable speed supplies the combustion air. You set the feed and the fan on the analogue control panel.

The burner has double flashback protection, electronic and mechanical, and a fire extinguishing system. Software keeps the flame alive. If the fuel runs out, the fan stops and the panel shows it.
