CapaciTorr HV

The CapaciTorr® HV pumps integrate the ZAO® high vacuum NEG alloy specifically conceived to sorb large gas throughput at pressure levels as low as 10-7 Torr. CapaciTorr HV benefits:

• utmost capacity for all active gases
• possibility to start the activation at low vacuum (i.e. 1e-2 Torr)

To exploit these benefits, the Capacitorr HV pumps must be operated permanently warm at around 200 °C. All the available models feature easily replaceable NEG cartridge.

Notes:

Pumping speed data refer to the initial values measured at pump inlet.

The capacity values (except for H2) are intended as the recommended absorbed quantity per run at around 200 °C, allowing to perform more than 20 sorption cycles. In case of operation under lower gas loads or at RT, the pump can be reactivated 100 times or more.

The values for H2O are estimated.

(*) The values for CO can be assumed very similar to those reported for CO2.
