Product Features

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.

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 gases

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.

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.

INNOVATIVE 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.
