Traditional approaches to pollution control have been to develop benign, non-polluting processes or to abate emissions at the tailpipe or stack before release to the atmosphere. A new technology called PremAir® Catalyst Systems1 takes a different approach and directly reduces ambient, ground level ozone. For mobile applications, the new system involves coating a heat exchange device in a vehicle, such as the radiator or air conditioning condenser. The catalyst converts ozone to oxygen as ozone-containing ambient air passes over the coated surface of the radiator. The technology is relatively simple and provides a positive benefit to the environment while being totally passive to the end user application. Volvo Car Corporation was the first automobile manufacturer to voluntarily introduce the technology on their S80 luxury sedan. Nissan Motor Corporation is also using the technology on their new Sentra CA (Clean Air) certified PZEV vehicle for California.

Classical approaches to pollution control have been to develop benign, non-polluting processes or to abate emissions at the tailpipe or stack before release to the atmosphere. A new technology called PremAir® Catalyst Systems1 takes a different approach and reduces ambient, ground level ozone directly. This technology takes advantage of the huge volumes of air which are processed daily by both mobile and stationary heat exchange devices. For mobile applications, the new system involves placing a catalytic coating on a vehicle's radiator or air conditioning condenser. For stationary applications, the catalytic coating typically is applied to an insert, which is attached to the air conditioning condenser. In either case, the catalyst converts ozone to oxygen as ozone containing ambient air passes over the coated radiator or condenser surfaces.
