Double pipe box

Double Pipe Box – Efficient Dual-Pipe Fuel Extraction for Hopper-Bottom Silos

The Double Pipe Box is engineered for reliable extraction of biomass fuel from hopper-bottom storage silos. Built in durable galvanised steel, it ensures long-lasting performance and smooth, uninterrupted fuel flow towards the heating system.

Optimised Fuel Extraction

Designed specifically for dual-pipe (bitube) systems, the Double Pipe Box uses airflow to fluidise the pellets and reduce material pressure.
Its pyramidal top prevents compaction and ensures a constant, clog-free extraction process—ideal even in demanding conditions.

Easy Maintenance and Practical Design

The unit features generous inspection openings that simplify cleaning and routine checks.
Installation is quick and straightforward, making the Double Pipe Box a practical choice for both new and existing biomass systems.

System Compatibility

The Double Pipe Box is compatible with most biomass suction and feeding systems.
The only excluded model is the AP1000.50.01 Nova 2.
This versatility ensures easy integration with modular or integrated pellet transport systems.
