Vacuum pump with quiet operation

Edwards

Edwards is launching the new air cooled nXLi dry vacuum pump range, ideal for applications where consistent performance, reliability and control are required. The nXLi provides a small footprint with quiet operation, making it a convenient and high performing yet compact vacuum pump.

The intelligent drive enables the system to achieve an enhanced performance plateau from single-phase power supply, with consistent worldwide operation. There is a choice of control options, with either manual, simple remote or serial communications control as standard, allowing more flexible control options for the system builder. The pump mechanism is non-contacting and oil-free to provide extended operation with maximum up time, up to five years’ service life.

During the initial chamber pump down the intelligent 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 enables the pump to overcome initial gas loads and once operating pressure is achieved, less power is required.

This new single-phase pump is available in two options, nXL110i and nXL200i, both optimised for LCMS (liquid chromatography – mass spectrometry) and ICPMS (inductively coupled plasma mass spectrometry) duties, and capable of handling gas loads of up to 25 slm.
