ExxFire-750 CNF Fire Suppression system

Integrated smoke detection and fire suppression system for small enclosures up to 1.5 m3. Possible to interconnect up to 8x units for a protected total volume of 12 m3.

Aspiration detection

The three optical sensors are the most sensitive smoke detectors in the market. Our specially developed software combines the readings of each detector and optimize them to prevent false alarms. An electrical fan samples the air in the protected volume continuously providing a fast smoke detection.

Non-pressurized nitrogen gas storage technology

The system provides 1 Cool Gas Generator capable of producing 750 l or 0.9 kg of nitrogen at ambient temperature to secure 1.5 m3. The low pressure and low noise level gas output does not interfere with the integrity of the IT equipment. This type of gas storage is maintenance free with a shelve life of 10 years.

Flexible user interface

The user Interface shows full system status, fault codes, mute and disable. The User Interface can be placed on three positions on the system to provide optimal access.
