Trailer & Container Smoke Testing
Fast & Effective Trailer Leak Detection with Superior® Smoke
Leaks in trailers and cargo containers can result in water infiltration, damaged cargo, and wasted energy. However, with Superior® Smoke, the professional’s choice for over 60 years, you can easily pinpoint even the smallest trailer and container leaks in minutes! Simply place one or two Superior® Smoke Candles inside the trailer, shut the doors, and observe the exterior. Superior® Smoke will quickly fill the space and escape through the leaks allowing you to identify and mark them for repair. It’s that easy!
