Packed pumping systems


Packed pumping systems

•Features
TMP-specification version added to Packed pumping systems line, which has been well accepted by our customers,
Shorter rough evacuation time implemented by the introduction of 3-directional valve, which allows rough evacuation to be executed through a separate line,
Use of 100 VAC for power source, suitable for R & D activity,
No cooling water needed,
Simplified Pirani gauge installed as standard
Installation of cold-cathode gauge or ionization gauge possible as an option,
Replacement of pumping set with that of existing diffusion pump is simple because of identical dimension design between the two.

•Application :
Pumping system of dry process
Various pumping systems
Research and development
