DENSPLUS Pressure Vessel

The Core Pressure Vessel for Dense Phase Conveying

DENSPLUS is the core conveying vessel of VOLDE Dense Phase Conveying Systems, engineered to introduce powders and granules into the pneumatic conveying pipeline under controlled pressure and air conditions. Each vessel is configured according to the material characteristics, required conveying capacity, pipeline geometry and operating conditions to provide controlled material discharge and reliable dense phase conveying.

| Controlled Conveying Cycle

DENSPLUS operates through an automatically controlled conveying cycle. Material is transferred from the upstream silo, hopper or process equipment into the pressure vessel. Once the required filling condition is reached, the inlet is isolated and the vessel is pressurized with compressed air. The material is then discharged into the conveying pipeline under controlled pressure and air flow.

After conveying is completed, the vessel is depressurized and automatically prepared for the next filling cycle. The complete sequence is managed by the control system to provide repeatable and reliable operation.

• Automatic vessel filling and inlet isolation
• Controlled pressurization and material discharge
• Pressure monitoring throughout the conveying cycle
• Automatic depressurization and cycle restart
• PLC-controlled operating sequence
• Integration with upstream and downstream process equipment

| Vessel Geometry & Material Discharge

Reliable dense phase conveying begins with consistent material discharge from the pressure vessel. DENSPLUS vessel geometry, cone configuration, material inlet and outlet arrangement are therefore selected according to the flow characteristics of the conveyed product.

For cohesive and poor-flowing powders, vessel geometry and air introduction can be adapted to promote material movement and reduce the risk of bridging or incomplete discharge. Air injection and flow-assistance solutions can also be incorporated where required to establish stable material flow from the vessel into the conveying pipeline

• Material-specific vessel and cone geometry
• Optimized inlet and discharge arrangement
• Application-specific outlet sizing
• Controlled air introduction into the vessel
• Configurations for free-flowing and poor-flowing materials
• Flow-assistance options where required

| Vessel Design

Each DENSPLUS is sized according to the complete conveying requirement rather than vessel volume alone. Capacity, bulk density, material flowability, conveying distance, vertical lift, pipeline diameter and cycle time are evaluated together to determine the appropriate vessel configuration

| Industrial Construction

DENSPLUS is designed for demanding industrial operation with carbon steel, AISI 304 or AISI 316 stainless steel construction options. Different vessel volumes, process valves, instrumentation, PLC/SCADA integration and ATEX configurations can be provided according to project requirements

| Integrated Air & Pressure Control

The performance of DENSPLUS depends not only on pressure vessel geometry, but also on how compressed air is introduced and controlled throughout the conveying cycle. Vessel pressurization, conveying air and process valves are coordinated to establish the required discharge and pipeline flow conditions.

For long conveying distances, complex pipeline routes or materials requiring additional flow control, DENSPLUS can be integrated with VOLDE AIRPLUS Conveying Air Control. Controlled supplementary air is introduced at engineered locations along the pipeline according to material behavior, pressure profile and conveying conditions

By engineering the pressure vessel, air management and conveying line as one integrated system, VOLDE configures DENSPLUS around the actual material and process requirements rather than applying a standard conveying arrangement
