New accessory interface for Pfeiffer vacuum pumps of the HiScroll series
Pfeiffer Vacuum introduces the new intelligent AccessLink accessory interface, which enables the use of a wide range of optional accessories with the HiScroll vacuum pump series. It is automatically recognized by the electronics. Previously, the accessories first had to be configured manually.
The new uniform accessory interface means more convenience and safety when operating the HiScroll series pumps. Pfeiffer Vacuum's HiScroll series consists of three dry, hermetically sealed scroll pumps with a nominal pumping speed of 6 to 20 m³/h. These vacuum pumps feature high performance when evacuating against atmosphere and very high energy efficiency to reduce the carbon footprint. A new gas ballast valve detects individual process requirements fully automatically. The vacuum pump controls the valve either over a specific time interval or depending on the inlet pressure in combination with another accessory, the RPT 010 sensor, which is exclusively available from Pfeiffer Vacuum and integrated into the HiScroll. The automatic gas ballast valve can also be switched manually by a higher-level control system connected to the HiScroll or the Pfeiffer Vacuum OmniControl.
Operational safety is increased by new vacuum safety valves. The valves prevent a pressure rise at the vacuum flange when the pump is switched off. This significantly increases operating safety, especially in the event of power failures. Any backflow into the vacuum chamber, also in the form of residual gas present in the pump system, is thus prevented. Time-delayed opening upon start-up of the HiScroll also prevents a pressure surge toward the vacuum side, which is particularly advantageous for high vacuum systems in connection with the operation of turbomolecular pumps, such as the Pfeiffer Vacuum HiPace. Fully automatic pressure control is handled by the RPT 010 gauge, which is optionally integrated into the pump. This minimizes wear in the pump, extends maintenance cycles and reduces the HiScroll's power consumption and carbon footprint. Fabian Böcher, product manager at Pfeiffer Vacuum, says, "The proven Pfeiffer Vacuum quality, together with the new accessories, ensures long operating life and lower operating costs and environmental impact. The easy maintenance of the pumps not only brings short service times, but also the highest possible availability. The pump system's built-in safety valve at the outlet and the pump's self-regulating operation ensure safe use." With these features, HiScroll vacuum pumps cover many application areas in the fields of analytics, biomedicine, pharmaceutical industry or research & development. They are used in mass spectrometry, electron microscopy and surface analysis as well as in accelerators and laboratory applications, but also in semiconductor technology, coating or gas recovery.
