Accurate and Reliable Gas Monitoring - Indoor Parking Garages

Exhaust ventilation controlled by Belimo's gas monitors provides a safe, clean environment and helps to keep energy costs in line. Using carbon monoxide and nitrogen dioxide gas monitors in parking garages offers accurate and reliable exhaust ventilation control where diesel-powered vehicles may also be present. The modular design provides a combined unit with carbon monoxide and nitrogen dioxide sensors within one device, helping to reduce energy costs by measuring emissions and only exhausting heated or air-conditioned air when needed. All vehicle emissions gas monitors (CO, NO2, CO + NO2) are certified under UL 2075 and ULC-S588, the gas and vapor detectors and sensors standards to UL.
