Energy efficient vacuum pumps<br />
Leybold has reduced <strong>the</strong> energy<br />
consumption of <strong>the</strong>ir diffusion<br />
pump series DIP and DIJ by applying<br />
intelligent technologies<br />
and optimising <strong>the</strong> design. Now<br />
a number of optimised models<br />
and accessories are available. The<br />
DIJ family offers connections <strong>for</strong><br />
both ANSI and ISO flange components<br />
as well as various electrical<br />
variants. The five-stage<br />
nozzle system of <strong>the</strong>se pumps<br />
has been improved <strong>for</strong> <strong>the</strong><br />
pressure range from 10 -2 to10 -3<br />
bar. The greatest energy savings<br />
potential was achieved by selecting<br />
an improved heating system<br />
and adjusting it to produce<br />
<strong>the</strong> propellant stream. In addition,<br />
energy is saved by an optimised<br />
arrangement of <strong>the</strong> heating<br />
elements in <strong>the</strong> boiler<br />
room, <strong>the</strong> loss-free energy<br />
transmission and <strong>the</strong> <strong>the</strong>rmal<br />
insulation. An integrated energy<br />
regulator that is based on monitoring<br />
<strong>the</strong> oil and heater temperature<br />
in <strong>the</strong> boiler room<br />
makes sure that <strong>the</strong> applied propellant<br />
fluid works at its optimum<br />
temperature. In total,<br />
energy savings of up to 50 %<br />
compared to unregulated stand -<br />
ard pumps are possible.<br />

Precise control of<br />
low flow rates<br />
The Flow-control series by<br />
Bronkhorst is a series of manually<br />
operated, pressure compensated<br />
control valves that are<br />
designed <strong>for</strong> low flow gas and<br />
liquid applications. The desired<br />
flow rate is set via a needle<br />
valve. Any upstream or discharge<br />
pressure variations are<br />
automatically compensated by a<br />
built-in membrane-operated<br />
valve to ensure a steady, constant<br />
flow. The valves are available in<br />
four different models to control<br />
gas flow rates in <strong>the</strong> range of<br />
0.02 to 50 l/min (N 2 -equiva-<br />
lent) and liquid flow rates from<br />
3 to 1800 ml/min (<strong>for</strong> water).<br />
While process connections are<br />
optionally available, <strong>the</strong> in-line<br />
valve assemblies are usually<br />
equipped with G 1/4" BSPP female<br />
in- and outlet ports.<br />
