The logistics industry faces persistent challenges in safely transporting and storing powdered materials like bulk cement and limestone. Delltank, a leader in tank container solutions, has introduced its 20-foot ISO bulk powder cement tank to address these challenges with a robust, multi-modal transport solution.

Delltank's ISO-certified container enables efficient powder transportation across diverse environments—from overland routes to maritime shipping lanes and railway networks. Engineered for bulk cement, limestone powder, and similar materials, the tank meets rigorous international safety standards while optimizing operational efficiency.

The container boasts a 22,500-liter payload capacity within its 26,000-liter total volume. Its 20-foot ISO frame construction ensures structural integrity during transit. Notable performance features include:

• Operating temperature range: -19°C to +80°C (-2.2°F to 176°F)
• 4.5mm thick Q345B steel cylinder with 5.0mm thick end caps
• Working pressure: 2.2 bar (32 psi), tested to 3.3 bar (48 psi)
• Pressure relief valve settings: 2.2 bar / -0.21 bar vacuum

The design incorporates multiple productivity enhancements:

• 500mm (20-inch) top manhole with secure sealing mechanism
• Air supply requirements: 0.2–0.3 MPa at ≥8 m³/min
• Quick-connect 100mm air inlet and 4-inch metric outlet
• Discharge rate: 1.0–1.5 tons/minute (for 30m horizontal/vertical transport)
• Residual rate: ≤0.3% (≤100kg for cement)

The container holds multiple international certifications including ASME Section VIII Division 1 (where applicable), TIR, CSC, and ISO standards (668, 6346, 830, 1496/3, 1161). It also carries certification from the China Classification Society for maritime applications.

Standard features include:

• 400mm wide anti-slip steel walkway with galvanized mesh
• Optional safety handrails
• Rear-mounted document pouch and grounding cable
• Stainless steel specification plate

The tank's design accommodates four primary use cases: cement storage, short-sea shipping, ocean transport, and rail carriage. This versatility enables seamless intermodal transitions across transportation networks.
