GDA - Gas & Smoke Aspirator Systems
GDA gas and smoke aspirator systems provide a unique solution for accurately monitoring gas and/or smoke ingress in areas where it is not practical to place a detector.
Aspirating smoke detection systems can be used in both high and low operating temperatures. Common aspirating smoke detector usage applications include: crude oil drilling areas and storage tanks, FPSO ballast tanks, FPSO turret moonpools, offshore riser caissons, and gas turbine intake and exhaust areas.
