Vulcain VA301IRFSR22 Sensor

The Vulcain VA301IRFSR22 is a professional-grade R-22 refrigerant gas sensor engineered for precise leak detection in commercial and industrial mechanical rooms. This NDIR (Non-Dispersive Infrared) sensor serves as a direct M-505418 replacement, ensuring seamless integration with existing Honeywell 301-EM series controllers. Designed for "at the source" monitoring, it features a rugged ABS-polycarbonate housing that facilitates mounting directly on chiller pads or low-wall positions where R-22 refrigerant, which is heavier than air, typically accumulates. Operating on a 12 VDC power requirement, this unit provides early notification to maintain ASHRAE 15 and B-52 code compliance, effectively mitigating safety risks in chilled water plants and refrigeration facilities.

• Precision R-22 Detection: High-accuracy infrared sensing technology minimizes false alarms from cross-sensitivities with cleaning agents or other solvents.
• OEM Compatibility: Specifically designed to replace the M-505418 and interface with 301EM-20 systems without requiring extensive rewiring.
• Durable Construction: The low-profile, impact-resistant enclosure is built to withstand the vibrating and humid environments of active mechanical rooms.
• Regulatory Alignment: Helps facilities adhere to refrigerant leak detection safety standards and environmental reporting requirements.
• Simplified Maintenance: Diffusion-based technology eliminates the need for external pumps or filters, reducing long-term service overhead for contractors.

Is this sensor compatible with newer HFC or HFO refrigerants?
No, this specific model is calibrated strictly for R-22 refrigerant gas. For systems utilizing R-410A or R-134a, a different sensing element tuned to those specific infrared signatures is required.

What is the typical coverage area for a single VA301IRFSR22?
In a standard mechanical room, the detection radius is approximately 20 feet (6.1 meters). Industry best practices recommend placing sensors within this distance of potential leak sources like valves, fittings, and compressors.

Does this unit function as a standalone alarm?
This is a remote sensor designed to transmit signals to a 301EM series controller. It requires the central controller to manage relay outputs for exhaust fans, strobes, or horns.
