Advanced screw Technology:
·
Edwards tapered screw
technology results in smooth, gradual compression along the length of the rotor
for improved thermal control and optimised pumping at all the inlet pressures.
·
The cooling system and compression
technology deliver outstanding performance and achieve temperature control
protects the pump from thermal shocks, condensation and corrosion.
·
Advance machining techniques
and design features eliminate the need of for rotor coatings while maintaining
superb ultimate vacuum performance.
Pump
speed control / PID control 4-20 m A Input
This application is
important to be able to adjust the speed of the pump whilst it is on-process,
either to a set speed or to control speed continuously to maintain a process
pressure. The CXS has capability to run the dry pump at various speeds whilst
on-process and it is possible to configure these speeds by a number of
different methods.
The CXS has a built-in
Proportional-Integral-Derivative (PID) Controller. When the PID
function is enabled and the pump is on-process, the PID controller continually
adjusts the speed of the pump so that the user-determined pressure is
maintained at the chosen pressure sensor.
