We have a huge library of 'Consensus' plates, from a range of plate manufacturers.

What are 'Consensus' plates?

• Idealized plates from original manufacturer concept drawings, software databases and public guess-work

• RareTechSEA has combined the following databases into a common database:

  • Honeywell Unisim, AspenOne EDR, HTRI Xphe, OEM's

  • Where slight geometrical differences existed, these were rationalised

  • M6-(H) is an example of an H 'consensus' plate

    • Note the '-' used in RTCalc software

We have a huge library of 'Measured' plates, from a range of plate manufacturers

What are 'Measured' plates?

• These plate geometries come from aftermarket plate manufacturers who have accurately measured the geometry of plates they have received directly from the original plate manufacturers (OEM's)

• RareTechSEA has combined the 'consensus' and 'measured' databases into a common table:

  • Consenscus and measured plates are listed alongside each other in this table

  • M3~(H) is an example of an H 'measured' plate

    • Note the '~' used in RTCalc software

• H = High plate chevron angle (Hard, high theta, or thermally long plate)

• L = Low plate chevron angle (Soft, low theta, or thermally-short plate)

• M = Medium plate chevron angle (combine H and L plates in the PHE pack - thermal plate mixing)

• Before adding plates into our operational  RTCalc software library, we perform exhaustive performance cross-checks and calibration

• Some plates are in the process of calibration
