FirePASS SCU3X/SCU2X for protecting small rooms such as archives, server rooms

The SCU3x oxygen reduction fire prevention system offers the same sophisticated features that are included in all FirePASS self- contained systems, including three compressors, air quality and moisture management, automatic heat and a touch screen control panel.

The SCU3x produces a controlled oxygen-reduced air environment, monitored by advanced oxygen analysers that measure the effective O2-level in the protected area. This enables the control unit to maintain a stable hypoxic atmosphere by switching the SCU3x on and off, depending on the defined O2-level, while also providing energy savings.
