Polytron IR — Dräger Polytron IR Fixed Infrared Gas Detector
The Dräger Polytron IR is a fixed infrared gas transmitter providing long-term stable hydrocarbon gas detection for Saudi Arabia's refinery and petrochemical LEL monitoring requirements. Unlike catalytic bead sensors that degrade in H2S-rich environments, the NDIR infrared sensor maintains measurement accuracy without poisoning in Saudi Aramco sour service hydrocarbon facilities. The Polytron IR's NDIR technology measures methane, propane, hexane, and other hydrocarbon gases with response times less than 15 seconds for fast alarm initiation. SIL 2 certified performance with fail-safe design ensures continued protection even during sensor failure conditions. The stainless steel weatherproof housing with IP65 protection withstands Saudi Arabia's extreme temperatures from winter Riyadh to summer coastal refinery environments.

Key Features & Benefits
- NDIR infrared measurement principle provides catalytic-poison-free hydrocarbon detection in Saudi Aramco sour gas facilities where H2S rapidly degrades conventional sensors.
- SIL 2 safety certification with fail-to-alarm design ensures Saudi Aramco SAES-B-068 performance requirements for safety-rated LEL detection are maintained during instrument faults.
- HART digital communication enables Saudi Aramco DCS to remotely verify sensor health, calibration history, and obtain zero and span calibration data without field access.
- T90 response time under 15 seconds provides fast alarm for Saudi refinery hydrocarbon vapor accumulation before dangerous concentrations reach ignition sources.
- 316 stainless steel housing resists corrosion from Saudi coastal salt air and hydrogen sulfide in sour gas processing environments without accelerated surface degradation.
Industrial Applications in Saudi Arabia
- Saudi Aramco crude oil pump station and pipeline manifold LEL monitoring for methane and heavier hydrocarbon gas leak detection with SIL 2 performance.
- SABIC ethylene and propylene storage sphere perimeter LEL monitoring for flammable gas cloud detection before ignition distance limits are breached.
- Aramco offshore platform process deck LEL monitoring where catalytic sensors are routinely poisoned by sour oil production gases.
- Saudi Aramco LPG storage and loading facility LEL monitoring for propane and butane leak detection at storage spheres and loading gantries.
- MAADEN gas-fired furnace area LEL monitoring for natural gas leak detection in high-temperature process areas where sensor longevity is critical.
