Agras T25 PN 001438 Seed and Fertilizer Dispersion Tank | High-Performance Payload

In high-performance unmanned aviation, modularity is the factor that defines the economic viability of a fleet. The Agras T25 PN 001438 Dispersion Tank is the central component for the mission transition of the T25 platform, allowing the aircraft to switch between liquid spraying and solid spreading with surgical precision.

For the aerospace sector, handling seeds and granular inputs requires a design that minimizes structural resistance and maintains the dynamic stability of the UAV. This reservoir is not just a container, but an engineered piece molded to optimize material flow and ensure the aircraft's center of gravity remains within operational limits throughout the discharge. At Magallan Aerospace Supply , we deliver this original component as the gold standard for aerial seeding and fertilization operations.

What it is and how it works.

The PN 001438 Dispersion Tank is a technical polymer reservoir designed for the spreading system of the Agras T25 drone. With a volumetric capacity of 35 liters (supporting a nominal load of up to 25 kg), it acts as the supply chamber for the rotary disperser module.

Its operation is based on a gravity-assisted exhaust system. Solid material is loaded through the wide upper opening and flows to the tapered base, where it attaches to the wiring mechanism and the dispersing disc. The tank works in conjunction with electronic weighing sensors, which send real-time data to the flight controller, allowing the drone to adjust the flow gate opening according to ground speed, ensuring a constant application rate (kg/ha).

Operational Applications in Aviation and Drones

Precision Seeding and Reforestation

It allows for the uniform distribution of seeds in hard-to-reach areas or in soils that cannot support the weight of ground machinery, making it ideal for pastures and environmental restoration.

Topdressing and Solid Fertigation

Application of urea, granular fertilizers, and soil amendments with total dispersion control, avoiding waste and ensuring homogeneous crop nutrition.

Dispersal in Aquaculture

Used for automated feeding in fish farming tanks, where the drone follows pre-programmed routes to distribute feed in a balanced way over the surface of the water.

Technical and Operational Benefits

• Operational Reliability: Manufactured with polymers resistant to impacts and chemical corrosion, ensuring a long service life even under severe use with abrasive fertilizers.
• Flow Precision: The internal design prevents material buildup on the walls and the formation of "bridges," ensuring that the input flows uninterrupted.
• Reducing Logistical Failures: The quick-lock system allows for tank replacement in seconds, optimizing the refill cycle and maximizing flight time .
• Simplified Integration: Native fit into the T25 airframe, eliminating the need for modifications and preserving the aircraft's structural integrity.
• Performance Optimization: The aerodynamic geometry reduces lateral drag, allowing the drone to maintain stability in crosswind flights.

Key Technical Differentiators

• Large Diameter Loading Opening: Designed to facilitate quick gravity-fed or manual refilling, minimizing material loss.
• UV-protected material: Prevents reservoir degradation caused by prolonged sun exposure during field operations.
• Shielded Coupling: The lower interface of PN 001438 is designed for superior sealing, preventing dust or fine particles from reaching the electronic connectors of the spreading system.
• Reduced Tare Weight: Lightweight construction that prioritizes the drone's power-to-weight ratio, allowing for a greater net payload.

Technical Specifications

Compatibility and Installation Requirements

• Target Aircraft: Exclusive to Agras T25.
• Required Components: Requires the Agras T25 Spreading System (Motor and Disc) for full functionality.
• Installation: Direct replacement of the liquid tank. It is recommended to check the seals of the dispersion module before final coupling.

Important Technical Guidelines and Considerations

1. Component Hygiene: Clean the tank with compressed air or running water after use with corrosive fertilizers. Wet residue can oxidize the drone's weighing mechanisms.
2. Density Calibration: Remember that different seeds have different flow rates. Always perform discharge calibration in the control application before the mission.
3. Flight Safety: Never exceed the recommended payload capacity for the T25. Excess weight in the solids tank may affect the response of the propulsion engines during emergency maneuvers.
