OptiAir Environment

Solution for healthy working environment

OptiAir Environment consists of environment control systems and processes that create a healthy working environment and comfortable mill environment by controlling noise, dust, emissions and machine hall air quality. Processes to achieve these goals are sound attenuation both inside and outside a mill, winder dust removal, machine hall ventilation and wet end process ventilation.

Controlled machine hall environment

 

For controlling and reducing emissions and creating good indoor air quality with environment control systems, Valmet has developed a 3-stage approach. The primary stage includes the capture of noise, dust, gaseous compounds, moisture and heat at the source. Emissions are captured by local exhausts, air curtains, dust and mist collectors immediately when formed and are transported away without fouling the surrounding air.

Primary stage capture at source

Secondary stage containment near source
