Flexibility and low energy consumption
Fuller Technologies is a leading provider of alternative fuels (AF) solutions. We offer a wide range of products, such as the PFISTER® TRW-S/D Rotor Weighfeeder, Feedex™ Overhead Reclaimer, the FUELFLEX® Pyrolyzer, and the HOTDISC® Reactor. We also provide the patented FEEDflex™ technology, which significantly lowers the minimum feed rate (feed range 1:100) of the PFISTER® DRW Rotor Weighfeeder. This enables the highest possible AF substitution rates and maximizes primary fuel savings.
Versatile solution for AF
Suitable for a wide range of alternative fuels (AF), including:
- Refuse-Derived Fuels (RDF)
- Municipal Solid Waste (MSW)
- Biomass materials such as wood chips and rice husk
- Many other non-free-flowing materials
Ideal for storing and handling non-free-flowing fuels with maximum reliability.

Safe enclosed operation
Reliable reclaim for non-free-flowing and compressible alternative fuels
Non-free-flowing and compressible fuels - dry and wet RDF, MSW, wood chips, rice husk - behave unpredictably in storage. They compact under their own weight, bridge across discharge openings, and leave dead zones that reduce effective capacity. Conventional storage concepts were not designed for these materials.
Feedex is designed for exactly these conditions. Inside the enclosed box, the overhead frame moves continuously - distributing, stacking, and reclaiming material to ensure complete discharge with no bridging and no dead zones. The system eliminates the blockages and uneven flow that cause downstream instability, keeping material moving from storage to reclaim without interruption.
Flexible storage configurations for controlled blending and consistent firing
The modular design - from a single box to multiple boxes - is flexible to match the needs of each plant. You can store different fuel types in separate boxes and blend the fuel to facilitate optimal firing. The system is optimised for blending fuels and ensures AF homogenisation - both in the box and between boxes.
The technology is proven to handle extreme climates, at temperatures from -25 °C to +50 °C. The drive in the Feedex frame is designed with a built-in dust filter and a self-cooling motor, maximizing reliability even in the most demanding operating conditions.
The system supports a high Thermal Substitution Ratio (TSR) in both the kiln and calciner, significantly reducing fuel costs and helping plants become more sustainable - ultimately lowering the CO₂ footprint.
The Feedex overhead reclaimer is suitable for several sizes of alternative fuel:
- Main burner: 30×30 mm (2D)
- Calciner: 100×100 mm (2D)
- HOTDISC® Reactor: 300×300 mm (2D)
- Gasifier: 300×300×300 mm (3D) - particles < 1 kg
- HOTDISC® Reactor: 300×300×300 mm (3D) - particles < 1 kg
