Point of use Purifiers:

The V-Purge system enhances the performance of our HP Series palladium membrane hydrogen purifiers. The patented system provides improved performance to handle any flow change, superior protection from power failures and pressure surges and fast switching from nitrogen purge to full hydrogen flow.

Any Flow Rate - Anytime
The improved design includes preheating of the inlet hydrogen to ensure stable temperature during purification. This control allows rapid changes in flow rate with no loss of pure hydrogen output.

Fastest Purge Performance
Residual hydrogen must be removed from the palladium membranes upon loss of power to prevent stress in the palladium lattice structure. The patented V-Purge system provides automatic purging to remove all hydrogen in minutes, well before the palladium can cool below 300ºC. The patented system (US2004/0182239A1) greatly improves MTBF performance to provide longer lifetimes.

Pressure Surge Protection
Flow orifices and programmed valve sequencing provide slow pressurization of the palladium purifier to prevent unnecessary pressure surges. This system design helps maintain stable operating conditions for the entire purifier to extend operating lifetime.

Rapid Startup
The vacuum-assisted V-Purge System rapidly removes nitrogen when the system is ready for restart. Now, the purifier can immediately restart to full hydrogen flow in <1 minute.
