The REMBE EXKOP Express is the central control unit for REMBE's explosion isolation system, designed to detect an incipient explosion and activate connected isolation valves — QV II, QV III, Q-Bic, RSV, and REDEX Slide — within milliseconds to prevent flame and pressure propagation through interconnected pipework. Installed outside the hazardous area in a sheet-steel enclosure, the EXKOP Express continuously monitors all connected detectors, isolation devices, and its own internal electronics through self-diagnostic routines.

How does the EXKOP Express trigger isolation in an explosion event?

The controller accepts trigger signals from a range of detection devices: REMBE Q-Rohr signalling units, explosion vents with integrated signalling, pressure sensors, infrared flame detectors, and spark detectors. Upon receiving a valid trigger, the EXKOP Express simultaneously activates all assigned isolation valves — quench valves close within milliseconds, while slide valves (RSV, REDEX Slide) and flameless devices (Q-Bic) deploy according to their mechanical response characteristics. All isolation devices are fail-safe: they close automatically on loss of power or compressed air, ensuring the protected equipment is isolated even during a utility failure. After an event, the controller logs the incident and the system can be reset at the push of a button, provided the mechanical isolation devices are re-armed.

What diagnostic and communication capabilities does the controller offer?

The EXKOP Express records up to 100,000 events with timestamping, providing a complete operational history for safety audits and incident investigation. Potential-free relay contacts — scalable from 4 to 64 depending on system size — transmit alarm, fault, and maintenance status to the plant PLC or DCS. Optional features include a touch panel HMI for local visualization, remote access via modem or Ethernet, and integration with the REMBE iQ Safety Cockpit for centralized monitoring of multiple EXKOP controllers across a plant. The controller is rated IP54 as standard, with an IP65 TriCon variant available for harsh industrial environments.

Which isolation devices does the EXKOP Express control?

All controlled valves are ATEX and EN 15089 certified, rated for dust explosions up to KST 300 bar·m/s, and feature EN 1092-1 PN 10 flanges as standard.
