CNG / Propane Fleet Maintenance Facilities

Municipal transit systems are upgrading their fleets to clean-energy CNG and Propane–powered buses. Ino-Tek is working with Architects, Engineering firms and directly with municipalities in the design and installation of upgraded Gas Detection systems to protect people and property as the transportation industry incorporates the exciting clean energy technology.

As transit systems upgrade their bus fleets to clean-energy CNG and Propane engines, Gas and Vapor Detection systems designed for diesel are no longer sufficient. Unlike diesel fuel, with it's low flash point, a CNG or Propane vehicle stores dangerous quantities of flammable CNG or Propane and if fuel tanks or systems were to leak, these highly flammable fuels could place the entire facility and all it’s occupants at the risk of a fire or explosion.

Understanding the actual clean energy fuel adopted is critical to sensor selection and placement. CNG is lighter than air and Propane is heavier. The large spaces involved create ventilation dead zones where leaking gases can accumulate. Smoke testing can help identify trouble spots.

Gas and Vapor Detection systems are critical to keep drivers and other employees safe from CNG and Propane leaks that could result in fires and possible explosion – threatening people, the buses and even, the facility.
