Vulcain gas detection systems are designed for use in a diverse range of commercial applications, from refrigerant systems and mechanical rooms to parking structures and office complexes. Each of these applications has its own set of requirements, both legal and practical, and Vulcain is committed to working closely with its clients to ensure all of these needs are met. In order to simplify purchasing and installation for our customers, Vulcain offers complete product packages for use in common gas monitoring situations.

Some of the more common air quality hazards include:

- Refrigerants in mechanical rooms
- CO and NO2 in indoor parking garages
- CH4 in boiler rooms
- Freon in grocery stores
- CO2 for demand control ventilation

- Flammable gases
- CO, CH4, O2 and H2S in waste water treatment plants
- CO in aerospace, automotive industries
- Cl2 in pools
- Propane in ice arenas and parking garages
