1.3.3 Operation diagrams
How to read the operating diagram for nitrogen for the
TURBOVAC 850i:
With deploying a SCROLLVAC 7 plus backing pump gas flows may be trans-
ported permanently with maximum throughput quantities of
■
0.2 mbar·l/s (with convection cooling),
■
0.5 mbar·l/s (with air cooling at 40 °C), and
■
approx. 5 mbar·l/s (with cooling water at 35 °C).
These values result of the intersection between the limitations of the individual
cooling variant and the pumping speed of the backing pump given. As can
be seen, maximum permanent gas flows are not solely a TMP characteristic,
but are dependent from the installed backing pump, too.
