Open Air Line ESP

Improve air quality along highways and beltways

If you live close to a highway in the Netherlands, you are inevitably subjected to fine and ultra-fine particles, also called “particulate matter” or PM. PM is harmful to health and it has a major impact on the development and availability of major roads. The engineers at Antea Group have developed a technology that significantly improves air quality along highways, beltways and tunnel entrances: the Open Air Line ESP.

Particulate matter is everywhere, all the time. It’s hardly surprising that, in the Netherlands, a significant amount of the particulate matter (PM) is made up of sand and salt. Emissions from industry and traffic also have a major effect on the composition of PM in this country however. The closer you get to busy roads, the more PM includes soot from diesel engines and fine particles contributed by tire wear and brake wear. 

Open Air Line ESP reduces PM by 75 to 80 percent.

Exceeding particle pollution standards
Air quality standards regarding particulate matter are being exceeded more and more often. Not only does this have an adverse effect on public health, it also affects the flow of traffic, accessibility of cities and the options for constructing roads and new housing developments. For the busiest beltway in the Netherlands “Ring Rotterdam”, for example, a maximum speed of 80kph (50mph) has been set in order to deal with PM pollution.

Improved air quality
Antea Group has developed a solution to tackle particulate matter and improve air quality. The Open Air Line ESP is an air vent that is placed on top of a noise barrier. The air vent makes use of the electrostatic fields and turbulence around the noise barrier. This technology captures at least 75% of the particulate matter, resulting in a significant improvement in air quality.
