Webber EMI manufactures a wide range of SHEDs in a variety of sizes, ranging from 10 cu-ft Micro SHEDs to full sized Vehicle SHEDs capable of testing HD construction vehicles. Starting from one of our standard configurations, a SHED can be designed to customer specifications with regard to size, window placement, vehicle door type, and other performance or capability options.

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. These upgrades can even be performed on-site, after installation.

FV/FT Vehicle SHED

The Webber EMI Model 101 Vehicle SHED is available as a Fixed-Volume / Fixed-Temperature (FV/FT) full-vehicle test chamber used for evaporative emissions testing. It is also suitable for testing motorcycles, small tractors and other machines & equipment of similar size.

VV/VT Vehicle SHED

The Webber EMI Vehicle SHED is also available as a Variable Volume / Variable Temperature (VV/VT) SHED. This SHED is designed to support a full range of test protocols and temperature profiles between 45 ºF and 120 ºF. Using the Webber EMI moveable roof system, absolute SHED volume is automatically controlled to maintain zero-differential pressure between the SHED interior and ambient laboratory conditions.

On-Board Refueling & Vapor Recovery

Webber EMI can provide On-Board Refueling / Vapor Recovery (OR/VR) capability for any of our SHEDs. Using several different methods, vehicles or other fuel-dependent machines can be re-fueled while the SHED is sealed.

Running Loss SHED

The Webber EMI Model 106 Running Loss SHED is a modified version of our full-sized Vehicle SHED. This extra long SHED, equipped with special air handling equipment, a proportional speed fan, vehicle combustion makeup air, and an auxiliary personnel door, is combined with a centrally located dynamometer to accept both front and rear wheel drive vehicles. In addition to full exhaust emissions testing capability, this SHED supports all applicable diurnal evaporative emissions test protocols.

Micro SHED

The Webber EMI Model 103 Micro SHED is designed for testing discrete fuel system components such as fuel containers, hoses, and canisters as well as complete miniature systems or engines.

Mini SHED

The Webber EMI Model 102 Mini SHED is suitable for testing small equipment such as ATVs, lawn mowers and other objects equivalent in size.

Vehicle SHED

The Webber EMI Model 101 Vehicle SHED is suitable for testing large equipment such as cars, trucks, tractors and other large machinery.


All Webber EMI SHEDs are available as full VV/VT enclosures, or as FV/FT enclosures that can later be upgraded to VV/VT capability.
