Product Features
CONTROL
Integral PID pressure control with in-built inverter for consistent operation. Data monitoring via on-board communication controller. Special start-up and shutdown modes available.SAFETY
Explosion tested and certified by independent authorities to meet strict safety standards. ATEX compliant for T4 IIB/IIB3 gasesINNOVATIVE SCREW TECHNOLOGY
Tapered-screw technology for improved thermal stability and optimised pumping at all inlet pressures. The cooling system and compression technology deliver outstanding performance and active temperature control protects the pump from thermal shocks, condensation and corrosion.EFFICIENT MOTOR AND DRIVE SYSTEM
Compact, high-speed motor with smaller footprint and lower noise. High start torque for maximum restart capability and reduced bearings temperatures for longer life.RELIABILITY
No end-compression plate to create potential for trapped solids, jammed rotors and hydraulic locks. No interstage condensers to create the potential for corrosion.PERFORMANCE
Continuous vacuum from atmosphere to 10⁻³ mbar for a robust, repeatable process. Deeper vacuum than traditional technologies and not limited by seal fluid or cooling water temperature.
