Easy Filter Change Out
The Rheo Vacuum Conveyance System Receiver has a side-entry filter change out that reduces receiver stack-up height and improves access. We also offer an optional safe-change filter option.
Clean in Place Design
The Rheo Vacuum Conveyance System has an integrated full-flush CIP system in the receiver head and can additionally be equipped with a retractable spray device to ensure coverage.
Product Testing
Rheo has extensive experience with the vacuum conveyance of numerous types of bulk solids, however every product is unique and needs to be tested using application-specific conditions to confirm the transfer rate.
- Process verification testing at Rheo provides proof of concept testing for new projects.
- The Rheo Testing Center has many on-hand powders in inventory as well as a testing performance database for reference.
- Multiple vacuum line configurations, diameters, lengths, and heights are set-up in our Testing Center for a wide range of testing options.
