SP series flat-bottom silos: reliable grain storage with minimal losses
SP series flat-bottom silos are the optimal combination of capacity, reliability and modern technology.
Key features:
- Capacity: volume from 417 to 25,450 m³, storage of up to 20,360 tonnes of grain.
- Efficient discharge: most of the grain is discharged by gravity through special openings in the flat bottom.
- Storage versatility: the silos are suitable both for long-term storage of conditioned grain and for temporary storage of wet grain (with ventilation and cooling).
Design advantages:
- High-strength materials: the walls and vertical stiffeners are made of high-strength steel grades using modern metalworking technologies.
- Roof truss system for silos over 11.45 m in diameter — made of galvanized high-strength sigma profiles (up to 4 mm thick).
- Reinforced roof structure: roof sheets with stiffening ribs and reliable sealed joint assemblies.
- Manufacturing precision: the tolerance for the process holes is no more than 0.003 mm.
Loading and unloading systems:
- Conveyor galleries of various widths (1,400 mm, 2,100 mm, 2,480 mm) to accommodate one, two or three conveyors.
- A gentle silo-loading system.
- A gravity side-discharge system.
- Enclosures for open-type belt conveyors (made of profiled metal sheet or sheet polycarbonate) for protection against precipitation.
Ventilation and monitoring systems:
- Active ventilation as standard:
- roof air ducts in the form of TsAGI deflectors (operate thanks to the reduced pressure created by the wind);
- perforated panels for high-quality aeration of the product.
- Optional ventilation with 100% floor-area coverage — for maximum efficiency.
- Turbo deflectors (optional) — increase ventilation efficiency fourfold thanks to the rotation of the active head under wind action.

Thermometry system for monitoring grain temperature:
- fastening elements and from 3 to 19 suspensions to the roof;
- thermal suspensions with sensors;
- a thermal-suspension polling unit;
- the ability to monitor using a portable reader or via the computer in the operator's station.

Additional conveniences:
- a ladder on the silo wall (from the service platform to the roof);
- an additional service hatch with a service platform.
