CARBOROBOT BIO wood pelet models are characterised by their large manual feed fuel container placed on the boiler. The wood pellet is feeded manually by the operator. The is ideal for single building heat, or multiplayed for the district heating plants.
They have instrumentation calibrated for the 3bar 95°C water or 0,5bar 115°C Steam

These models have large container what can be refilled manually or using the optional refilling auger (sold separately). There is two version of fuel container. Front feeding need for the manual feed or for the screw feeder. Top feeding good for external feeder system placed over the boiler or when using pathway over the fuel container. The size of this container varies from type to type, accomodating a quantity enough for autonom continuous operation at maximum performance of several days in the case of small boilers (40kW) and of 10-20 hours in the case of large ones.
Fuel is forwarded onto a rotating grate where it is burnt under automatic control. Cinders fall into the ash chamber wich is large enough to accommodate a quantity resulting from the burning of a whole container-load of fuel. Heating water is warmed up by the hot flue gas trough a heat exchanger. The flue gas is forwarded into the chimney by a special fan, so the boiler does not depend on chimney draught. Even after several days of being out of operation, combustion starts up automatically. This means that it is enough to starts up the boiler only once a year. These boilers do not require continuous supervision: they must only be re-filled with fuel and freed from cinders from time to time. Once set, they maintain an excellent combustion level ell trough the season, so properly set boilers do not smoke at all. The automatization level of CARBOROBOT boilers is equal to that of oil or gas boilers; they can be installed in any place where similar equipment the heating system do not defer. These boilers can be controlled by water or room thermostats. They can also be used with the most up-to-date, digital, programmable controls.
Thermal efficiency of the CARBOROBOT 78-90% and the nominal output power given with the fuel 17MJ/kg(4000kcal/kg)

Each type possible to produce in low pressure Steam mode (0,5bar 115°C) (exclude C30)
