Dräger Polytron 5720 IR

Advanced Stationary Carbon Dioxide Detection

The Dräger Polytron 5720 IR is an explosion-proof, industrial-grade stationary transmitter designed for the continuous monitoring of carbon dioxide (CO2) in ambient air. Utilizing a state-of-the-art infrared sensor (Dräger PIR 7200), this high-performance device delivers exceptional speed of response, precision, and long-term stability. The advanced optical system is optimized for CO2 detection, making it an ideal choice for facilities requiring strict atmospheric controls and reliable hazard prevention.

Fail-Safe Infrared Technology and Simple Maintenance

Unlike traditional electrochemical sensors that suffer from early exhaustion or drift, the optical infrared technology inside the Polytron 5720 IR is immune to sensor poisons and operates reliably in oxygen-deficient or completely inert environments. The transmitter features a fail-safe optical arrangement that alerts operators if the beam becomes blocked by dirt or dust. A clear, backlit graphical display presents real-time CO2 measurements and diagnostic statuses, while a non-intrusive design allows users to calibrate and manage configurations via a magnetic wand without opening the explosion-proof enclosure.

Rugged Architecture and Standalone Flexibility

Engineered for extreme environmental climates, the housing is available in either copper-free aluminum or premium 316 L stainless steel, boasting an IP65/66/67 ingress protection rating to resist heavy rain, washdowns, and dust. For applications requiring localized controls, an optional integrated relay module expands the unit into an independent safety node. This module provides two gas alarm relays and one fault relay to instantly activate external horns, strobes, or ventilation systems without relying on a central panel.

Industrial Applications and Use Cases

• Carbon Capture & Storage (CCS): Monitoring infrastructure for localized carbon dioxide leaks and transportation line drops.

• Food and Beverage Industries: Protecting personnel from CO2 accumulation in breweries, bottling plants, and cold storage facilities.

• Chemical and Petrochemical Processing: Managing process safety where carbon dioxide is utilized as a feedstock or byproduct.

• Water Treatment Facilities: Monitoring surrounding air quality where CO2 is injected for pH neutralization.
