4 General
C 2214 Chlorinators are designed according to the highest safety standard DIN 19606. Several functions going
beyond that standard. With these devices so-called full-vacuum installations can be set up with vacuum begin
-
ning directly at the chlorine cylinder. Even in the case of a line rupture chlorine gas cannot escape.
The full-vacuum chlorinator is of central importance for the safety in vacuum installations and provides the
following functions in addition to the vacuum regulation which is the basic function:
Components and functions of C 2214
Residual pressure pres-
ervation
against a complete evacuation of the cylinder in order to avoid corrosion
caused by humidity of the entering air.
Filter
Filter for protecting the valves against dirt particles from the cylinder or from
the connection area.
Cylinder pressure ma-
nometer
for display the pressure inside the chlorine tank.
Safety blowoff valve
for protecting the vacuum system against overpressure even in the case of a
clogged inlet valve.
flow limiter
against icing of the cylinders as a result of an inadmissably high chlorine
delivery rate.

The ejector are realised as stand alone products. Thus a flexible installation of the system perfectly adapted to
the conditions on site is possible.
The back-pressure regulator required according to the German standard DIN 19606 is used to avoid metering
faults as a result of priming pressure fluctuations of the ejector. It is integrated in the ejector non-return valve
and therefore does not require additional installation space or time.
In addition to the generally needed elements, there is a number of expedient auxiliary devices. For example,
distribution blocks distribute the chlorine gas flow to several metering points and back stops improve the safety
of the system to a much higher level than required according to regulations. For a constant chlorine delivery
even if chlorine cylinders are becoming empty, an automatic switch-over is required. Several versions are
available. One version up to a rate of 10 kg/h even works without auxiliary energy. Electrically actuated control
valves are installed at an arbitrary point between flow meter and ejector back-pressure valve in the vacuum
line. Therefore the installation of automatically working systems is easily possible.
