Webber EMI manufactures evaporative emissions testing systems in a variety of sizes. We provide Micro and Mini-SHEDs suitable for component permeation testing and small engines, to Vehicle SHEDs capable of testing Medium Duty Trucks. Starting with one of our standard configurations, an evaporative emissions testing system can be custom-built to our customer specifications regarding size, window placement, access door type, and other performance or testing needs. All Webber EMI SHEDs incorporate a modular-systems design that allows the basic Fixed Volume / Fixed Temperature (FV/FT) enclosure to be upgraded to full Variable Volume / Variable Temperature (VV/VT) enclosure — even years later — on-site, and after installation.
