Applications
The UVU-140-A & UVU-140-AR fire detectors respond instantly to ultraviolet radiation emitted by a flame.
These devices are designed for use in hazardous locations and are suitable for use in outdoor applications.
Typical applications for UV detection systems
< around highly combustible materials
< when instantaneous response to flame is needed or where automated fire protection is required
< protection of large capital investments
Petroleum Products Handling
< petroleum loading terminals
< offshore platforms
< pipeline stations
< tank farms
< refineries
< engine rooms
Gaseous Fuel Handling
< butane and propane loading and storage
< pipeline compressor stations
< gas gathering facilities
< LNG loading, transfer and storage
< hydrogen
< gas turbines
Other Processes
< paint spray booths
< chemical and petrochemical production
< powder coating booths
Automated fire protection systems also have applications in any manufacturing or research facility where the
potential of fire may be low to moderate, but the losses due to a fire would be high.
