Hy-Alerta™ – Reliable Fixed Hydrogen Area Monitoring for Critical Safety

Protect people, assets and uptime – with real-time hydrogen detection where it matters most.

Hydrogen is a valuable energy carrier, but also a safety risk in enclosed or poorly ventilated areas. Hy-Alerta™ from H2Scan is a solid-state fixed area monitor, specifically designed to detect hydrogen leaks quickly and accurately – ensuring protection in environments where safety cannot be compromised.

What is Hy-Alerta?

Hy-Alerta is a family of solid-state, hydrogen-specific area monitors designed for fixed installation in zones where hydrogen presence must be continuously monitored. Built on patented sensor technology, Hy-Alerta delivers real-time gas detection with no cross-sensitivity, no calibration drift, and no carrier gas required.

✅ Available in general purpose, intrinsically safe, and explosion-proof models

✅ Certified to international safety standards (ATEX, IECEx, CE, UL, CSA)

Why Choose Hy-Alerta?

✅ Hydrogen-Specific Accuracy

Hy-Alerta sensors are only responsive to hydrogen – not oxygen, methane, or other gases – which eliminates false alarms and ensures fast, accurate action in case of leakage.

✅ Real-Time Safety

With a response time of just a few seconds, Hy-Alerta allows operators to react before gas concentrations reach critical levels.

✅ Maintenance-Free Operation

The latest models, such as the Hy-Alerta 5000 series, feature auto-calibration technology – eliminating the need for routine field calibration. This drastically reduces downtime and maintenance cost.

✅ Flexible Installation

Available for:

  • ATEX Zone 1/2 hazardous areas
  • Indoor and outdoor industrial settings
  • Battery energy storage systems (BESS)
  • Hydrogen refueling stations
  • Gas compressor rooms and filling facilities

Each model supports analog output (4–20 mA) and digital protocols (Modbus RTU), enabling seamless integration with SCADA, DCS or building management systems.

 Typical Use Cases

  • Battery Rooms & Energy Storage Systems (ESS)
    Prevent hydrogen accumulation from overcharging or failure conditions.
  • Hydrogen Production & Fueling Infrastructure
    Monitor critical points in electrolyzers, storage, compressors and dispensers.
  • Control Rooms & Critical Environments
    Early leak detection protects staff and ensures continuity of operations.
  • Warehouses with Fuel Cell Vehicles
    Hydrogen-powered forklifts and AGVs introduce new safety risks – Hy-Alerta mitigates them.

 

Customer Benefits

  • ✓ Enhanced safety compliance – Meets international codes for hydrogen detection
  • ✓ Zero drift and calibration-free – Avoids service interruptions
  • ✓ Cost-effective over lifecycle – Lower TCO vs. electrochemical or catalytic sensors
  • ✓ Easy to integrate – Standard outputs and protocols
  • ✓ Future-ready – Ideal for hydrogen expansion in new energy infrastructure
