Edwards is launching the air cooled nXLi dry vacuum pump range, which hopes to provide a small footprint with quiet operation.
There is a choice of control options, with either manual, simple remote or serial communications control as standard. The pump mechanism is non-contacting and oil-free to provide extended operation with maximum up time and up to five years’ service life.
During the initial chamber pump down the transient overload protection allows a higher power draw for a short period of time, this enables the pump to evacuate the chamber from atmospheric pressure to operating pressure. This higher initial power boost should enable the pump to overcome initial gas loads and once operating pressure is achieved, less power should be required.
