PremAir® Catalysts
PremAir® is approved by the Air Resources Board of California and U.S. EPA for Direct Ozone Reduction (DOR) emission credits that can:
Optimize engine performance at a bin classification
Reduce precious metal costs
Raise emission catalyst system engineering safety factor
Increase profitability of fleet vehicle mix with emission credits
PremAir® Direct Ozone Reduction (DOR)
PremAir® is a patented catalyst coating that transforms ground level ozone, the main component of smog, into oxygen. As air flows over a vehicle’s coated radiator, PremAir®catalyzes the reaction that converts ozone into oxygen. This process capitalizes on the large volume of air that passes through a vehicle’s radiator.
PremAir® NXT Next Generation DOR
With PremAir® NXT, even smaller radiators for today’s downsized 4 cylinder engines can convert as much ozone to oxygen as larger radiators with standard PremAir®. This allows Automotive OEMs to earn the full emission credit for California LEV III and U.S. Tier 3 emission regulations.
PremAir® NXT delivers value through emission reduction credits
PremAir® NXT is a DOR technology which has been validated for 150,000 miles or 15 years. Tier 3 and LEV III have approved an emission reduction credit of 5 mg/mile for DOR technology. OEMs can leverage this tool in a number of ways to deliver value to manage their fleet average emissions requirements.
Optimize engine performance
PremAir® NXT credits are a cost-effective alternative solution to PGM (Platinum Group Metals) content in catalytic converters and can be used to maximize engine performance at a bin classification.
Managing fleet vehicle mix
LEV III and Tier 3 require OEMs to change their fleet percentage sales to meet the emission standards, so OEMs have to sell more SULEV vehicles while selling less ULEV 125 vehicles. High performance sedans and coupes as well as trucks and SUVs are often more profitable but meet higher emission bins. Utilizing PremAir® NXT credits can enable OEMs to mitigate the impact of new regulations on their vehicle mix.
Engineering Safety Factor for SULEV
Performance at low NMOG and NOx levels is difficult to measure for both fresh and aged catalyst performance; borderline TWC aging performance can introduce risk to an OEM. PremAir® NXT credits can be leveraged to increase the safety factor at a vehicle bin classification.
Reduce cost
As regulations demand more out of catalytic converters, additional PGM content can have decreasing emission control efficiency. PremAir® NXT credits can help optimize PGM performance to reduce total emission control costs.
