ChlorGuard Electro-Pneumatic Control Panel
For many years, the bespoke ChlorGuard™ control panel provides a robust philosophy for valve shutdown while also offering feedback signals so that the end user can monitor the status of the system. Process functionality has also been built in to assist the end user with activities such as closing the gas valves of an empty vessel before replacing.

Design Features
Air Supply
- Recommend stand alone air receiver/compressor is used dedicated to ChlorGuard
- Sufficient Air for two closures
- System designed and approved to Pressure Equiptment Directive 2014/68/EU Module-H
Control Panel
- Standard panel uses Normally Closed Solenoid Vales (NC). This avoids plant shutdown when mains power fails and battery drains.
- Fail-Safe panel uses Normally Open Solenoid Vales (NO) to avoid potential plant shutdown when mains power fails and battery drains.
- One to four banks available for shutting down up to twenty cylinder valves or twelve drum valves
- For use with nitrogen or compressed air
- Battery back-up available for Standard and Fail-Safe
- Solenoid valves are activated by gas detection alarm or remote stop signal to the electrical control panel
- During closure compressed air supplied for up to 30 seconds
- Key Test function available
CE Conformity with:
- Machinery Directive (2006/42/EC)
- Low Voltage Directive (2014/35/EU)
