PC 3012 NT VARIO select DUOVARIO® chemistry pumping unit
Overview
- VACUU·SELECT vacuum controller with graphical user interface and predefined applications easy to integrate via digital or analogue interfaces
- automatic boiling point detection and adjustment of the vacuum for short process times
- meets high vacuum requirements for very large quantities of most high boiling solvents
- extraordinary diaphragm life for minimum operational and servicing costs
- excellent environmental compatibility through low energy consumption, no operating fluid needs (oil, water) and efficient solvent recovery
Ultimate vacuum
1.5 mbar
Ultimate vacuum with gas ballast
3 mbar
Max. pumping speed 50 Hz
28 m3/h
VARIO® chemistry pumping unit in action
The VARIO® DUO pumping units are consisting of a combination of two individual VARIO® pumping units, connected in parallel on the suction side and driven synchronously by one vacuum controller VACUU·SELECT. The vacuum is controlled accurately. The speed of the two individual pumps is exactly adjusted to the vacuum needs. The controller allows both fully automatic distillations without any user pre-settings as well as specific and reproducible program sequences. The integration into existing control systems via digital and analog interfaces is also possible. The consequent design to highest chemical resistance provides the ideal prerequisite for universal use in chemistry and pharmacy - without any operating fluid such as water or oil. The unique combination of high chemical resistance, very good ultimate vacuum and high pumping speed with low energy consumption and without any operating fluid makes the new VARIO® DUO pumping units the contemporary vacuum source for many applications in the range of kilo-lab, pilot and small productions. They are also used as network pumping units for larger VACUU·LAN® - installations or as an environmentally friendly alternative to existing central vacuum systems. The VARIO® control provides the required vacuum all the time and automatically adjusts the speed of the two pumps to the needs. This results in prolonged maintenance intervals in addition. The low noise level allows placement within the workspace.
