Affordable feed systems

  • Low purchase cost. FlowFeeda offers a low capital investment compared to fixed, shed-based feed systems.
  • Low energy usage. Energy reduction with low power consumption. Low electrical energy requirement from soft-start walking floor systems, offering the lowest kWe (Kilowatt-electric) cost per ton handled.
  • Low labour costs. A powerful combination of high capacity, secure storage and on-demand, automatic in-feed work together to minimise labour costs.
  • Low maintenance & ownership costs. Extremely low maintenance and ownership cost from robust, reliable, wear resistant hydraulic moving floor equipment.

    Designed simplicity

    • Designed simplicity. Robust, well proven, dual moving floors with no belts, chains, sprockets and very few moving parts. With simplicity comes reliability and with reliability comes low service and low ownership costs.
    • Proven to work. FlowFeeda has logged thousands of operational hours and demonstrated safe and effective continuous or pulse feeding at any time of year and at any temperature. Proven to deal with the inherent non-uniform characteristics of fuel.
    • Versatile and adaptable. Multi-purpose dosing and feeding module designed for uniform, slow moving delivery of wet or dry feedstocks, including; biomass, SRF and RDF, energy crops, alternative fuels and more.
    • Modular and scalable. Modular, compact, aesthetic design with a range of configuration options available. Stronga supply bespoke feed systems to accommodate different layouts and storage capacity requirements with varied throughput.

    Controllable capacity

    High capacity, plug and play fuel drawing systems, arranged to maximise timings between refilling.

    Stronga build bespoke, optimised dosing systems designed for your required capacity. Modular walking floor systems can be scaled up to increase capacities further with easy loading via fully opening roof arrangements.


    Success by controlling

    The level of controls range from a fully automatic, self-feeding unit to a stand-alone system, controlled externally. FlowFeeda is designed for highly varied throughput from very low hourly output to significant, extra high fuel delivery. Integrated self-protection features include thermal protection for the oil and time out protection.
