Chloro Tech - Construction and Function Vacuum Change Over Device

The vacuum change – over device is operable without auxiliary power. From which battery the gas is supplied, is indicated visually but as the option the change over position can also be remote indicated 2 reed contact.

As soon as the vacuum rises to a value of about 3-4 m ws/ 78”-118” wc, which can be caused by an empty or closed supply battery, the change over function is triggered.

The change – over device can be used in connection with the chlorine dosing units C 105 and V 107 or V 115.

NOTE: If the chlorine gas dosing units are retrofitted with the change – over device, a compensation for the main regulator has to be provided.

Connect the vacuum change – over device at the inlet side to two vacuum regulators and at the outlet side to the chlorine gas dosing unit. The inlet connections for the vacuum regulators are marked with the inscriptions IN I and IN II, the connection for the chlorine dosing unit with OUT.

The vacuum lines between the vacuum regulators and the change – over device should be kept as short as possible and should not exceed a maximum length of 6 m. Thus a minimum pressure loss can be ensured.

A pre-condition for trouble – free functioning of the vacuum change – over device is the tightness of all lines and connection.
