Webber EMI manufactures a wide range of evaporative emissions testing systems in a variety of sizes, ranging from 27 cu-ft Micro SHEDs to full sized 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 with specific regard to 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.
