- Automatic Emergency Shut-Off System for Chlorine Gas

From

0

Automatic closure of chlorine gas valves in seconds. The electrical Emergency Stop system provides additional safety for personnel and equipment by automatically closing off the chlorine gas supply. With its own operating unit and uninterrupted power supply, it reliably closes the chlorine gas valves in the event of an emergency, even following power failure.

Emergency shut-off system for chlorine gas – the new safety for your system

The DULCO Vaq emergency shut-off system for chlorine gas, coupled with a chlorine gas detector, ensures the automatic and immediate closure of the chlorine gas source in the event of a leak.

The actuator sits directly on the chlorine gas valve of each storage tank and is controlled by an operating unit. This transmits the signal to close as soon as the chlorine gas detector detects a leak. The emergency shut-off system then closes the storage tanks within a few seconds. All the back pressure connections to the vacuum regulator are thus closed preventing the escape of more chlorine gas. The emergency shut-off system can also be manually triggered by an emergency stop switch fitted outside the storage room. The operator must manually re-open the chlorine gas valves after cordoning off the surroundings and rectifying a possible leak.
