Diaphragm single stage automatic switchover board with manual reset - TDI102
The TDI 102 switchover board is ideally suited to insure gas supply from many high pressure sources of high purity corrosive gases with low flow. Dedicated to the supply of gas to analyzers and to the creation of controlled atmosphere in laboratories, control units, and for petrochemical applications.
Key advantages
- Possible to connect up to 6 cylinders without using the purge line
- Maintains purity: eliminates crossflow mixing of supply sources
- No risk that a source flows into the other one
- The automatic switchover board does not need to be reset to allow reversal of the cycle
- Ammonia version available on demand
- Ready to install with all components are mounted on a board
- Can also be equipped with an outlet shut-off valve
- Using contact gauges, the switchover board can also be equipped with an alarm box to indicate the source status
