Together with the burners RRR supplies feeding hoppers with a capacity of about 200 l. These hoppers deliver pellet directly to the burner, and are integrated in the burner control system to ensure an optimum pellet use.

Additionally, RRR can supply 300 l hoppers. 

However, aware of market demands and customer needs, RRR also offers the possibility of manufacturing tailor-made hoppers that fit into stairwells, garage nooks or whatever free space available.

Besides RRR manufactures outdoor silos where large users can store their biomass with no need for construction works inside machine rooms or buildings.

All these hoppers come with screw conveyors and sweepers described here.
