Macurco OX-6 fixed oxygen deficiency and enrichment detector for commercial refrigeration equipment rooms and confined spaces.

Key features

• Monitors ambient oxygen levels to detect both deficiency (below 19.5% O₂) and enrichment conditions
• 5 A SPDT fan relay enables direct control of ventilation or exhaust systems upon alarm
• 0.5 A alarm relay output connects to local notification devices or panel alarm inputs
• LED display provides continuous oxygen concentration readout for routine inspection
• Installs to standard 4×4 electrical box with mud plate for commercial wall-mount applications

The Macurco OX-6 is used in commercial refrigeration machine rooms where ASHRAE 15 and local codes require oxygen monitoring to protect personnel from refrigerant-related oxygen displacement. It is also suitable for confined space entry monitoring in mechanical and utility rooms. The relay outputs allow direct action on ventilation equipment and local alarms. The OX-6 monitors for both oxygen-deficient and oxygen-enriched atmospheres, covering applications involving inert gas purging as well as oxidizer storage environments.
