Description
FYRA for End of Primary Drying Detection | Vacuum Drying Monitoring | CE, UL, CSA
The DigiVac FYRA End of Primary Drying Detection package is designed for vacuum drying applications such as freeze dryers and vacuum ovens where monitoring the end of primary drying is critical. By comparing a convection-enhanced Pirani sensor with a gas-independent capacitance manometer, the system helps indicate when most water or residual solvent has been removed from the product.
During primary drying, the Pirani sensor typically measures a higher pressure because of the increased water vapor content generated by sublimation. As drying progresses and the amount of vapor decreases, the Pirani and capacitance manometer readings approach the pressure difference established in a dry, empty, refrigerated system. Approaching this established ΔP provides an indication that primary drying has reached its end.

FAQ
What is the FYRA End of Primary Drying Detection package used for?
The FYRA End of Primary Drying Detection package is designed for vacuum drying applications such as freeze dryers and vacuum ovens. It helps indicate when most of the water or residual solvent has been removed and primary drying has reached its end.
How does the FYRA system indicate the end of primary drying?
The system compares readings from a convection-enhanced Pirani sensor and a capacitance manometer. As drying progresses, the Pirani and capacitance manometer readings approach the ΔP established in a dry, empty, refrigerated system. Approaching that baseline indicates that the end of primary drying has occurred.
What vacuum sensors are included with the FYRA package?
The package includes a convection-enhanced Pirani KF25 gauge sensor with Lesker 275 components and a Quantum DCP gauge with DuoSENS capacitive piezo vacuum sensor and driver card. The DCP Quantum measures from 0.05 mT to 1000 Torr, while the Pirani measures from 0.1 mT to 1000 Torr.
Is the FYRA controller calibrated and does it support remote monitoring?
Yes. Each FYRA is calibrated and pretested under actual vacuum against a NIST standard. The controller also provides a remote command line interface through USB for remote control and monitoring from a computer.
