LAS VEGAS, Nev. — Mack Trucks will be showcasing its ClearTech emissions control system with selective catalytic reduction (SCR) at the upcoming World of Concrete show.

Mack says its ClearTech SCR technology has been proven to improve fuel economy by up to 5% while reducing active diesel particulate filter (DPF) regenerations. The company has been producing trucks with ClearTech emissions control technologies since November 2009, months ahead of the stringent EPA2010 emissions standards, the company claims.

The World of Concrete show will feature Mack Granite concrete mixers with ClearTech. Those trucks will also be participating in the Mack Driving Skills Safety Challenge outside the show hall.

“Mack’s ClearTech does it all – and does it better than other systems which aren’t even available yet,” said David McKenna, Mack’s director of powertrain sales and marketing. “It reduces NOx emissions to extremely minute levels, while effectively eliminating DPF active regens. That means better fuel efficiency and reduced operating costs.” 

Mack says its ClearTech emissions systems have completed more than five million miles of field testing in North America.

“ClearTech doesn’t change the design or operation of Mack’s great MP Series engines, and we’ve actually been able to increase horsepower ratings,” said McKenna. “Plus the improved fuel economy shrinks the trucks’ carbon footprint, reduces operating costs and cuts the need for imported oil.”

Mack claims the diesel exhaust fluid required by the SCR system will only need to be topped up once for every two to three refuels. The World of Concrete show is held in Las Vegas Feb. 2-5.
