Dri-sump® Containment Tightness Testing is a vacuum test method that is certified to test in ONLY 60 SECONDS! Dri-sump was sp ... ecifically designed to test all types of containment sumps and spill buckets. The test only takes 60 seconds and uses NO water, creates Zero waste. (Trademarks and Patent-pending US and all foreign) This method can quickly and safely test any open or closed top containment sump or tank, storage vessel, vault, or any other type containment to 0.10gph standard with no waste by-products and without water. It is capable of as low as 0.05gph when compared to other hydrostatic methods! Dri-sump® uses Aerosol Elixir™, a heavy vapor aerosol instead of water to quickly test all sumps and spill buckets. The test method requires filling the entire containment sump with heavy vapor aerosol (fog) (takes about 10 seconds for a 250-gallon sump). The aerosol is made from a proprietary formula of chemicals which are all food grade, pH neutral, non-petroleum based, and safe. The heavy vapor aerosol is simply introduced into the sump and then an air generator "pulls" (vacuum) the soil gases from around the sump into a viewing chamber. A laser is introduced into the viewing chamber. If a leak is detected, the tester will see a laser line that looks like a "green laser line". If no leak is detected, the laser merely makes a "dot". The Aerosol Vapor disappears in 5-10 minutes. You never lose a fuel customer with Dri-sump! Contact info@Dri-sump.com to schedule all your testing.
