1.11 Special notes for working with chlorine gas metering units and the usage of

chlorine

DANGER!

Chlorine is a hazardous material. The chemical element chlorine is a green-yellow, toxic gas with pungent

odor. It is 2.5 times heavier than air and accumulates at ground level. It is toxic when breathed in. In severe

cases chlorine may lead to death. It irritates the eyes, the respiratory system and the skin. It is very toxic for

water organisms. The reason for the toxicity of chlorine is its extraordinary reactivity. It reacts with animal and

vegetable tissue and thus destroys it.

Air with a chlorine content of 0.5-1% leads to a quick death of mammals and humans, because the respiratory

tract and the pulmonary alveolus are attacked (formation of hydrogen chloride or hydrochlorid acid).

DANGER!

Breathing in air with a chlorine content of 0.01% for hours may lead to mortal intoxications. Already a chlorine

content of only 0.001% (10 ppm) severely attacks the lungs. 0.0001% (1 ppm) of chlorine in breathing air

irritates the respiratory systems and is easily detected due to its odour. It is not hazardous in this case. The

threshold limit value is at 0.5 ppm.

In order to avoid hazardous incidents, make sure to do a maintenance of the chlorine gas metering units at

leastonceayear.Insomecases,regionalregulationsmayrequireshorterintervalsofmaintenance.Workingon

the system requires special safety precautions and may only be carried out by instructed technical personnel.

The operating personnel must be instructed and must know all operating instructions and regional regulations.

These must be available on site. The devices/system must be checked daily and after each maintenance or

repair work for leak tightness.

DANGER!

Leakages may cause a chlorine gas escape. Breathing in chlorine gas may lead to death! Make sure to im-

mediately eliminate any leakage. For all work on gas-conveying system parts, make sure to wear a functioning

respirator mask with ﬁlter and and to evacuate all chlorine from the system. This is also important when chang-

ing the chlorine cylinders. In the case of an escape of chlorine gas, use a self-contained breathing apparatus.

Only use sealings once, a second usage is not allowed and leads to leakage.

Before starting work on chlorine gas metering systems the cylinder valves must be closed. All chlorine leading

pipes must be evacuated using the ejector.

Liquid chlorine must never enter chlorinators not being explicitly authorized for liquid chlorine.

In case that the pressure gauge at the vacuum regulator still indicates a pressure, the pressure has to be

discharged using the ejector.

Before startup of the chlorination installation all connections must be carried out properly and tightened using

the suitable tools. The tightness of the whole installation must be tested using ammonia vapor (ammonium

hydroxide solution).

Chlorine gas is highly hygroscopic. Therefore humidity penetrates the system at every open connection of the

units or pipes resulting in the formation of hydrochloric acid thus inevitably causing damage of the units. In

such cases, damages of the devices are inevitable. Therefore all connections (at the vacuum units and vacuum

pipes as well) must be closed at any time.

If chlorinators must be used with other gases than chlorine gas, the chemical resistance of the unit must be

checked after consulting the manufacturer.

3 Functional principle of the vacuum regulator

3.1 Chlorine Gas

Chlorine gas is important for the disinfection of potable and swimming pool water but also represents a source

of danger as far as handling, transportation and storage are concerned. Therefore the vacuum principle has

been used in chlorination installations already for decades. According to this principle, the pressure of the chlo-

rine gas is reduced to vacuum, and only then, if the vacuum is sufﬁcient, will chlorine gas ﬂow to the metering

point. The main safety aspect is that the escape of chlorine gas is actually avoided. Even in the case of a line

rupture chlorine gas cannot escape but only ambient air can be primed.

3.2 Vacuum regulator

The full-vacuum chlorinator used as pressure reducing valve is of central importance for the safety in vacuum

installations. For this reason the C 2214 version has been designed in accordance with the latest ﬁndings.

The device combines several functions in one housing:

Fig. 1: Cross section C 2214 (under vacuum ﬂow to the vacuum line)

Functional principle of the vacuum regulator | Operation Manual C 2214 | 9

Fig. 2: Cross section C 2214 (under excessive pressure ﬂow through the safety blowoff valve)

Vacuum regulation

In the initial position the ball ①(see ﬁg. 3.1) rests on the valve seat ②. It is pressed onto the seat by the lock-

ing spring ③and the chlorine cylinder pressure and closes the system. After switching on the ejector (water-

jet pump), a vacuum is generated. The vacuum applies a force to the working diaphragm ⑦of the full-vacuum

chlorinator, which is directed to the right. This force is transferred to the valve ball ①by the valve rod jso

that chlorine gas enters the vacuum system. If the vacuum breaks down, the valve ball falls back immediately

onto the valve seat and stops the chlorine gas supply.

Flow indication and manual adjustment

An optional ﬂow meter is mounted on the front side of the C 2214 full-vacuum chlorinator. The positon of the

ﬂoat element kindicates the ﬂow directly at the scale on the gauge tube. Gauge tubes with maximum rates

between 25...4000 g Cl2/h are available. The chlorine gas ﬂow can be easily adjusted using the needle valve

llocated directly at the measuring glass holder.

NOTICE!

The constant volume of chlorine gas delivered per hour from one chlorine cylinder must not exceed 1 % of the

original contents. Consequently the maximum rate for e.g. a 65 kg cylinder is 650 g Cl2/h. Otherwise there

is a risk of cylinder icing. If larger amounts are required, the chlorine is supplied simultaneously from several

cylinders (see installation examples).

NOTICE!

For automatic control of chlorination an electrically operated chlorine control valve (e.g. C 7700 of the manu-

facturer) is used. If required, it is installed anywhere in the tubing line to the ejector non-return valve.

NOTICE!

If the chlorination installation is to correspond to the German standard DIN 19606, a back-pressure regulator

must be used, which avoids pressure ﬂuctuations in the system. (Is integrated in the non-return valve of the

manufacturer.)

10 | Operation Manual C 2214 | Functional principle of the vacuum regulator

Safety valve

If the inlet valve of the vacuum chlorinator does not close completely due to impurities, it is possible that an

excessive pressure develops in the vacuum piping system which causes undesired chlorination. To avoid this,

the safety valve is used. Even the lowest pressure causes the large working diaphragm ⑦to move to the left.

Thus the spring his compressed and the diaphragm disk ilifts off from the O-ring n. As a result a ﬂow

tunnel opens at the diaphragm disk, and the excessive pressure escapes into the left chamber of the vacuum

chlorinator. The end of the blowdown pipe is run near the gas sensor. Thus an immediate alarm signaling is

ensured.

Residual pressure preservation

Whileemptyingthechlorinecylinder,thecylinderpressuredecreasesuntilitistoolowtoremovetheball④

against the spring ⑥from the valve seat ⑤. A residual pressure of approx. 0.1 bar remains in the cylinder.

Thus humidity cannot enter the cylinder during replacement. The humidity of the entering air would cause

the chlorine cylinder to corrode internally so that the chlorine gas could be contaminated. Consequently, the

residual pressure preservation helps to extend the operational life of the chlorine cylinder.

Pressure gauge

The C 2214 chlorinator is equipped with an optional pressure gauge for the indication of the cylinder pressure.

The unit in question has a splash-proof measuring mechanism in a plastic housing. In order not to damage the

pressure gauge by dirt particles, the chlorine gas is directed to it through an integrated ﬁlter m.

The measuring range of the manometer of -1...0...15 bar was chosen in order to allow a supervision of the

residual pressure maintenance.
