Flush Gas Station, For Use with HIR Pyrometer
The Delta Controls Model HFI provides a low, filtered purge gas across the process side of the HIR lens glass to reduce particulates from building up on lens. The HFI provides a single place at the reactor where the operator can regularly monitor and verify proper operation of the flush gas stream.
Features
- Accurate continuous control of purge flow rate
- Insures long term temperature measurement reliability by sweeping dust and ash from the pyrometer lens window
- Corrosion resistant, suitable for the severe environments found in sulfur recovery units
- All stainless steel NACE compliance standard
- Mounts on a vertical surface or 2” pipe stand
- Labeled connections minimize connection errors
- Front mounted instructions encourage correct operation which will maximize pyrometer accuracy
