MTS - Open Containment with Vacuum Conveyance

Vacuum Conveyance Transfer with Open Containment

The Rheo Material Transfer Station is a small footprint workstation that improves operator safety and efficiency during the material transfer and weighing process. The operator workstation with the integrated drum tipper provides a compact, GMP, ergonomic means of transferring material.

The Material Transfer Station with Open Containment is designed for simple open transfers. Containment levels of 100-10 µg/m3 can be achieved via the integrated Rheo Ventilation Sleeve.

Rheo has conducted containment verification tests on the Material Transfer Station. The tests showed excellent results for each of the different configurations tested. Copies of the executive summary, full reports, and supplemental documentation are available upon request.

The Vacuum Conveyance configuration is used to transfer materials from drums to another vessel using a vacuum hose. The Material Transfer Station can utilize any vacuum source and delivers a complete package that addresses ergonomics, containment, and inerting concerns often associated with material transfer systems.

Rheo can provide the entire material transfer package including the vacuum pump and receivers or we can utilize your existing vacuum system to deliver a more ergonomic and contained dump station. The Material Transfer Station with Vacuum Conveyance can also be used to pull product directly into an evacuated process vessel so that a separate receiver is not required.


The Material Transfer Station with Open Transfer Containment has several benefits when implemented in the manufacturing process:  

  • Ergonomic Product Transfer
  • Quick Deployment
  • Limited Cleaning Time
  • Modular Design
  • Easy Access to Product
  • Portable Dispensing Suite
  • Containment (100-10 µg/m3)
  • Small Footprint

Vacuum Conveyance Hopper

The Vacuum Conveyance Transfer Module uses a hopper to hold product before it is pulled away using a vacuum source for vacuum conveyance. For Open Transfer Containment, the integrated Rheo Ventilation Sleeve provides containment across the top of the transfer module opening while the bottom is connected to a vacuum hose. Using this process to provide containment has been documented to keep operator particle exposure to 100-10 µg/m3.

For difficult powders the hopper can integrate the Rheo proprietary Actively Managed Plug Prevention Technology (AMPP) to optimize the product conveyance throughput. AMMP is a controls and automation sequence that monitors the powder flow in the vacuum line and automatically activates flow aids when material begins to build up in the line.


Dust Extraction

The integrated Rheo Ventilation Sleeve provides localized dust extraction to contain airborne dust and vapor. The full perimeter slot design provides 360 degrees of extraction to ensure that proper air velocity is maintained in the dust zone despite obstructions, such as an operator’s hands or a drum liner.

Rheo has conducted containment performance verification tests on the Material Transfer Station. The tests showed excellent results for each of the different configurations tested. Copies of the executive summary, full reports, and supplemental documentation are available upon request.

Common applications for Material Transfer Station with open containment

Common Applications

  • Subsurface Vacuum Additions
  • Small Port Vacuum Additions
  • Dry Granulation
  • Wet Granulation
  • Blender Filling
  • Vessel Filling

Integrated Weighing

The integrated weighing system provides a compact solution for the weighing and dispensing operation. The weighing module that holds the receiving container is isolated from the workstation to provide excellent weighing accuracy.

The typical integrated weighing system includes the following features:

  •     150 kg Weighing Capacity
  •     Mettler Toledo IND570 or IND560X Readout
  •     4x Mettler Toledo Load Cells
  •     Weigh Accuracy to +/- 50 grams (higher accuracy, low capacity options are available)
  •     Can be Integrated with Computer, PLC, or Printer

The Rheo design library allows our team to efficiently tailor our products to meet the specific requirements of each application. During the design phase, the Rheo engineering team analyzes the application to develop a custom and comprehensive material handling solution. By using standard options as well as custom-designed features, a GMP operator-centric design can be achieved. Various 3rd party components such as mills, RTP’s, or HEPA/carbon filters are often integrated into Rheo equipment to provide a custom turnkey product or system of products. 

Modular Design

To increase the utility of this equipment, Rheo has developed a quick and easy change over from an open transfer system (that uses a dust extraction device to capture fugitive dust) to a high-containment system that uses a flexible Restricted Access Barrier System (RABS). This modular design offers two levels of containment controls to accommodate the full span of compounds.

Transfer Modules are also designed to be quickly replaced in order to change between different types of receiving containers (example: change from a Drum to Drum Transfer Module to a Drum to Bag/Bottle Transfer Module).

Operator Centric Design

By designing around an analysis of operator movements during the drum charging process, an unmatched level of safety, operating simplicity, and functionality is achieved. A drum can be raised, lowered, and tipped into the proper position by using a single hand or foot control. This approach to drum handling allows the operator to easily control the product flow during the entire charging process.  

Material Transfer Station by Rheo is engineered with operator centric design.

Clean the entire Material Transfer Station


All exposed surfaces on the Material Transfer Station can be fully washed-down for cleaning. Some configurations of the Material Transfer Station include WIP spray-ball systems to wash the product contact surfaces. 

Testing Center

Powder handling can be a challenging process and there are many factors that lead to the optimal solution. We can handle the risk for you!
