Emissions Venting Hose Extracts High-Temperature Diesel Fumes
Unhealthy engine exhaust before venting emissions Vehicle exhaust gases are a health hazard in every fleet maintenance shop. Whether the vehicles are material handling equipment like fork lifts; over-the-road bulk material carriers; off-road monsters like road graders and dump trucks; fire trucks, delivery vans or security cars – all require engine maintenance.
Diesel engine manufacturers publish velocity and temperature data on vehicle exhausts detailing what rates to expect at various engine loads, like 40, 50 or 60 percent of maximum RPM. Vehicle maintenance professionals can use this data to design emission removal systems. These systems help keep the ambient air in repair facilities clean and healthy for the people working there.
Specialists who design and build vehicle exhaust removal systems incorporate Master-CLIP HT-1200 hoses for hi-temp diesel fume extraction. One highway maintenance and road surfacing company in the upper midwest who purchased such a system maintains a 32-vehicle fleet of jumbo-size asphalt resurfacing and paving equipment at its engine service facility near Lake Michigan.
– Emissions problem needed special exhaust hose to handle 1,200°F temperatures –
Masterduct’s rep, working with the shop foreman, determined the optimum specifications for a vehicle emission removal system that uses hoses specifically designed to withstand the kinds of high exhaust gas temperatures that road building vehicles produce. It features Master-CLIP HT-1200, a flex hose capable of withstanding "worst case scenario" temperatures of 1,200°F for sustained periods. A woven stainless steel liner inside the hose provides long life at high temperatures.
Photos show nozzle, hose, and hard piping that lead to a blower on the roof that vents the high temperature engine exhaust emissions. Masterduct’s representative also helped design a make-up air system that allows for homogenizing the air in the shop area. This consideration was really important in view of the area’s harsh winters and the need to replace fresh air inside the facility.
"It’s amazing," the shop foreman said of his new system. "You rev one of these Cat or Mercedes engines wide open, and you don’t see a bit of smoke come out of it." Judging from before-and-after pictures, that is quite an improvement.
