FirePASS® SCU2X / SCU3X Compact Oxygen Reduction Units

The FirePASS® SCU2X and SCU3X are compact oxygen reduction fire prevention units designed for continuous protection of enclosed spaces up to approximately 300 m³.

By continuously generating oxygen-reduced air, the SCU2X and SCU3X help maintain an engineered low-oxygen environment in which the risk of fire ignition is significantly reduced.

Their compact design makes these units particularly suitable for smaller protected environments where continuous fire prevention is required and installation space is limited.

Compact Oxygen Reduction Fire Prevention

The FirePASS® SCU2X and SCU3X provide a compact solution for oxygen reduction fire prevention in smaller enclosed spaces.

Instead of waiting for smoke, heat or flames to activate a conventional fire suppression system, FirePASS® continuously maintains an oxygen-reduced atmosphere designed to reduce the risk of ignition.

This proactive approach provides continuous fire prevention while avoiding the discharge of water or chemical extinguishing agents during normal operation.

How the FirePASS® SCU2X and SCU3X Work

The SCU2X and SCU3X use ambient air to produce oxygen-reduced air, which is continuously supplied to the protected environment.

By maintaining an engineered oxygen concentration, the system creates conditions in which common combustible materials are significantly less likely to ignite.

The required oxygen concentration and system configuration depend on the protected environment, the materials present and the specific fire prevention requirements of the application.

Fire Prevention for Rooms up to 300 m³

The FirePASS® SCU2X and SCU3X are designed for continuous oxygen reduction fire prevention in rooms with a protected volume of up to approximately 300 m³.

Their compact configuration makes them suitable for smaller controlled environments where critical equipment, valuable assets or essential operations require continuous protection.

Actual system selection and capacity depend on factors including protected volume, air leakage, required oxygen concentration and operating conditions.

SCU2X vs. SCU3X

The FirePASS® SCU2X and SCU3X provide compact oxygen reduction fire prevention for smaller protected environments.

The appropriate model is selected according to the characteristics of the protected space and the required system capacity. Factors such as room volume, air leakage, required oxygen concentration and application-specific operating conditions are considered when selecting the system.

Contact FirePASS® to determine whether the SCU2X or SCU3X is the appropriate configuration for your application.

Applications for the SCU2X and SCU3X

The compact SCU2X and SCU3X can be considered for smaller controlled environments where continuous oxygen reduction fire prevention is required.

Depending on the specific application and system design, potential applications can include:

• Server and IT rooms
• Electrical and technical rooms
• Small archives and storage rooms
• Equipment rooms
• Critical infrastructure spaces
• Other enclosed environments up to approximately 300 m³

Each application requires an engineered assessment to determine the appropriate FirePASS® system and operating conditions.
