Dräger VarioGard 2320 IR

Advanced Carbon Dioxide Monitoring for Commercial Safety

The Dräger VarioGard 2320 IR is a specialized, stationary gas transmitter designed for the continuous and precise measurement of carbon dioxide (CO2) in ambient air. Utilizing a state-of-the-art infrared (IR) optical sensor, this reliable device detects dangerous gas accumulation well before it compromises human health. It integrates seamlessly via the VarioGard digital bus system into a central controller, providing a highly automated and cost-effective safety network for modern facilities.

Poison-Resistant Optical Sensing and Maintenance-Free Operation

Unlike traditional electrochemical cells that suffer from fast aging or sensor drift when continuously exposed to background gas, the optical infrared technology inside the VarioGard 2320 IR is completely immune to sensor poisoning from silicones or volatile organic compounds. It operates with exceptional long-term baseline stability and require no routine chemical replacement. The unit features an integrated three-color local LED status indicator to communicate system readiness, maintenance faults, or gas alarms directly on the facility floor.

Efficient Digital Bus Architecture and Compact Housing

Engineered to minimize installation complexity and structural wiring costs, the transmitter communicates directly with the Dräger VarioGard central controller via a specialized digital fieldbus. This smart bus configuration allows multiple transmitters to be wired in a simple daisy-chain sequence, significantly reducing cable run expenses. The electronics are encased in a robust, compact plastic enclosure with an IP51 ingress rating, making it highly suitable for everyday indoor commercial environments and facility machinery rooms.

Industrial Applications and Use Cases

• Food and Beverage Logistics: Tracking localized carbon dioxide leaks in brewery cellars, beverage dispensaries, and cold storage units.

• Commercial Breweries & Wineries: Continuous room air surveillance around active fermentation tanks and chemical handling lines.

• Mushroom Cultivation & Greenhouses: Automated tracking of CO2 concentration baselines to optimize crop growth while protecting personnel.

• HVAC and Facility Control: Monitoring indoor air quality in large venues or plant rooms to actuate automated ventilation networks.
