2.3 Pressurized enclosure system F870S
2.3.1 Simultaneous PID- control of cabinet pressure and flow rate
Based on the first introduction of proportional valve technology within pressurized enclosure
systems (patented system Gönnheimer F850) an additional
active proportional valve
was
integrated to the F870S
in the outlet
.
Figure 2: block diagram simultaneous pressure and flow control
This concept permits simultaneous
PID-regulation of cabinet pressure and flow rate
and
generates new solutions and possibilities for pressurized enclosure systems and attach-
ments.
