Gas Detectors and Controllers

Gas Detectors & Controllers

For Refrigerants, Explosive Gases and Toxic Gases

Advanced Gas Detectors and Controllers for Complete Gas Monitoring Solutions

Ensure safety and compliance with proven gas detection systems and controllers. Our portfolio covers toxic gases, combustible gases, oxygen (O2), CO2, and refrigerants, delivering accurate, continuous monitoring for industrial plants, commercial buildings, labs, and HVAC/R environments. Protect people, equipment, and the environment with early leak detection, automated alarms, and seamless system integration.

Gas Detectors & Controllers

Why Gas Detection Matters

Gas leaks can cause explosions, toxic exposure, asphyxiation, and environmental damage. A robust gas detection strategy helps you prevent incidents, reduce downtime, and comply with safety regulations. With fixed and portable gas detectors integrated into a central gas controller, you gain a reliable early‑warning system that can trigger ventilation, shut down equipment, and alert personnel in seconds.

Key benefits:

  • Early leak detection to protect people, assets, and processes
  • Less refrigerant loss and lower operational risk
  • Support for regulatory compliance (EN, ISO, OSHA, local codes)
  • Data and event logs for audits and preventive maintenance

Our Gas Detection Solutions

We deliver an end‑to‑end portfolio tailored to your site and application risk:

  • Fixed Gas Detectors – Continuous, point or area monitoring for hazardous gases
  • Portable Gas Detectors – Single‑ and multi‑gas instruments for mobile teams
  • Gas Controllers – Alarm logic, relays for fans and beacons, BMS/SCADA connectivity
  • Accessories – Beacons, sounders, calibration kits, sampling and mounting hardware

🔹 Ideal for: machinery rooms, compressor rooms, boiler rooms, plant rooms, cold rooms, parking garages, tunnels, labs, and utilities.

Fixed Gas Detectors (Continuous Area Protection) for Toxic and Hazardous Gases

Fixed gas detectors provide 24/7 monitoring where leaks may occur—near compressors, valves, manifolds, joints, AHUs, chillers, and storage areas. Choose the sensor technology based on gas type, expected range, cross‑sensitivities, and ambient conditions. Our devices support configurable alarm thresholds, visual/acoustic alerts, and integration via 4–20 mA, Modbus, or BACnet (where supported).

Highlights:

  • Stable sensing for CO, H2S, NH3, Cl2, O2, CO2, hydrocarbons, and refrigerants
  • Rugged housings for industrial and commercial environments
  • Easy maintenance and service access for routine calibration

Refrigerant Leak Detection (HVAC/R & Cooling Systems)

Refrigerant gas detection protects people, product, and equipment while supporting F‑gas and safety compliance. We monitor HFCs, HFOs, CO2 (R744), ammonia NH3 (R717), and hydrocarbons (R290/R600a) in machinery rooms, chillers, cold rooms, plant rooms, and ORC systems. Detection enables early maintenance, automated ventilation, and system protection—reducing leak‑related downtime and refrigerant losses.Ideal for any application requiring a stationary refrigerant monitoring system to ensure safety and compliance.

What sets our refrigerant monitoring apart:

  • Sensor options matched to gas and range: NDIR (HFC/HFO/CO2), electrochemical (NH₃), MOS/catalytic (hydrocarbons)
  • Placement based on gas density and likely leak sources (compressors, valves, evaporators)
  • Controller integration to drive fans, beacons, and interlocks; BMS connectivity
  • Support for typical standards and good practices (e.g., EN 378, ASHRAE 15, ISO 5149, local codes)
