CapaciTorr HV

The CapaciTorr® HV NEG pumps are equipped with the ZAO® getter alloy, a high-performance Non-Evaporable Getter (NEG) material specifically designed for high vacuum applications. This advanced alloy ensures efficient gas sorption even at pressure levels as low as 10⁻⁷ Torr, making the CapaciTorr HV pumps ideal for environments requiring ultra-clean vacuum conditions.

Key benefits of the CapaciTorr® HV series:

• Maximum sorption capacity for all active gases
• Early activation capability at low vacuum levels (e.g., 10⁻² Torr)
• Consistent high vacuum performance when operated at ~200 °C

All models feature an easily replaceable NEG cartridge, ensuring long-term maintainability and optimal operation for high and ultra-high vacuum systems.

Notes on pumping performance and gas sorption:

The pumping speed values refer to initial performance measured directly at the NEG pump inlet under standard test conditions.

Reported gas capacity values (except for hydrogen) indicate the recommended amount absorbed per sorption cycle at approximately 200 °C. Under these conditions, the CapaciTorr® HV pump can perform over 20 effective gas sorption cycles.

In applications with lower gas throughput or at room temperature, the pump can be re-activated more than 100 times, maintaining high performance in high vacuum environments.

The values for H₂O sorption are based on internal estimations.

(*) Values for CO sorption can be considered comparable to those reported for CO₂.
