Applications

• A control feature for the explosion suppression system that manages the HRD cylinders, pressure sensors and IR detectors.
• The CIE multi-zone control unit provides explosion suppression system monitoring, relays the stored energy impulse to trigger the HRD cylinders, and on-line verification of the system status.
• The modular architecture enables selective (zoned) activation of the explosion suppression system (e.g. limited to an equipment unit where an explosion occurred).

Specifications

• The CIE control unit receives, controls and evaluates the outputs from pressure, spark, flame and temperature detectors.
• The HRD explosion extinguishing cylinders are triggered selectively, depending on the configuration of the explosion suppression and isolation system.
• The system detection and activation lines are continuously monitored for shorting and loss of ground.
• Backed up with battery power for continued operation in the event of a mains loss.
• Individual zones of the system can be remotely armed or put offline.
• Integrated in massive switching cabinets with optional heating or air conditioning.
• Protection type: IP54, application: Zone 22, ambient temperature: -10°C to +40°C.
• ATEX-compliant design.
