We are working on the development of a system that facilitates the improvement of the air environment, by purifying volatile organic compounds (VOCs) released from production manufacturing sites and removing the suspended particulate matter (SPM) and nitrogen dioxide (NO₂) emitted from ventilation facilities in road tunnels.

In large metropolitan areas, there have been concerns about the effect on neighboring areas of the SPM and NO₂ contained in the exhaust gases released from road tunnel ventilation facilities. We delivered a denitrification system for low-concentration NO₂, consisting of an electlic dust catcher and low-concentration denitrification equipment for the Yamate Tunnel on the Central Circular Route of the Shuto Expressway in japan, which was opened to trafficin December 2007. We thus became the first supplier in Japan to deliver a denitrification system for a road tunnel. This has mitigated any local effects on the neighboring areas from SPM and NO₂ released from the ventilation towers of the Yamate Tunnel.

A vast amount of VOCs are emitted at plants where large objects, such as cars, aircraft, and ships are painted. Purification of exhaust gases at these plants requires highly advanced technology because of the nature of the process, that is, where objects are painted in a large space. Having developed an ultra-large painting environmental system based on VOC removal techniques, MEA supplies large-scale clean painting plants. New VOC regulations were introduced with the revision of the Air Pollution Control Law in April 2006. The revised law requires that companies should manage emission control goals and accelerate their efforts to reduce all such emissions. We are contributing to the improvement of the air environment by providing total solutions based on these regulations.

The VZ system is used for air-conditioning at factories and other large spaces. The system sends conditioned air only to where workers are active and lowers the sensed temperature by utilizing the wind-chill factor. In comparison with general air-conditioning, the VZ system can reduce initial costs and reduce CO₂ emissions by 30% during operation.
