Precision Refrigerant Detection. Engineered for Zero-Loss.
Irish-made, wired systems designed to protect your assets, your personnel, and the environment.
High Cost of a Silent Leak
Refrigerant leaks aren’t just a safety hazard; they are a massive financial and environmental liability. Between rising F-Gas quotas and the strict requirements of EN 378, “set and forget” safety is no longer an option.
Helio provides the most stable, wired refrigerant detection in the Irish market. Our sensors don’t just “detect” gas; they provide the granular data needed to identify slow-bleed leaks before they trigger a total system shutdown.
Core Product Pillars
- Non-Dispersive Infrared (NDIR) Technology
Unlike cheap semi-conductor sensors that drift and trigger false alarms from cleaning chemicals, Helio utilizes high-accuracy NDIR technology. It is gas-specific, long-life, and immune to “poisoning.” - Sequential Sampling Excellence
Our HELIO Chill-Ir system allows for sequential sampling of up to 16 points. This wired architecture ensures that even in massive cold-chain logistics hubs, every valve and joint is under constant surveillance. - Seamless F-Gas Logging
Compliance is built-in. Our control panels automatically log every event, providing the digital audit trail required for Irish and EU environmental inspections.
The HELIO Chill-Ir: The Professional Standard
- Target Gases: HFCs, HFOs, CO2 (R744), and Ammonia (R717).
- Low-Level Detection: Capable of detecting leaks as low as 10ppm for early warning.
- Rugged Build: IP65 rated enclosures designed for the thermal cycling of industrial freezers and plant rooms.
- Wired Reliability: Hard-wired back to the central hub, ensuring that if a sensor goes offline, you know instantly.
Applications
- Pharma & Life Sciences: Precision cooling for temperature-sensitive medicine.
- Data Centers: Monitoring large-scale CRAC units and liquid cooling loops.
- Food & Beverage: Ammonia and CO2 safety in high-volume processing plants.
- Commercial HVAC: Protecting occupants in hotels and offices using VRF/VRV systems.
