The Motorized Valve Control Unit (MVCU) provides the power and control for the stepper motor drive which moves the mechanical valve mechanism inside a valved effusion cell.
The Power Supplies PS and PID temperature controllers provide precise temperature control resulting in a stable flux within our effusion cells
Safety system which protects UHV-chambers from contaminations caused by unexpected warming up of the cryopump.
Manual and remote control of rotation speed, direction of rotation and start/stop is possible. The control signals can be set manually, with TTL signals or with external relays.
