ULG Recirculation air unit with turbulent mixed flow ventilation

For use in operating theatres of class 1b

Even operations with a lower infection risk place an increased demand on the room air quality. The ADMECO recirculation air unit with turbulent mixed flow ULG with EC fans ensures an intensive flushing of the operating theatre and reduces the concentration of harmful substances in the operating theatre with the usual reliability and energy efficiency, but without a defined protection area.

Ultraclean air is streamed in turbulently and draft-free from the ceiling via H14 high-efficiency particulate filters into the operating theatre and generally aspirated away close to floor level. In the process, the room air is mixed with the filtered air, and in this way, the airborne bacteria level is reduced to the desired minimum.

Costs & energy

Cost limitation and environmental protection are core concerns of ADMECO. With the ULG recirculating air unit, the effort to reduce energy consumption and costs has been intensified even further. The reduced space requirements for air channels, the smaller flow regulators and fire protection flaps as well as the lower proportion of fresh air lead to lower investment costs and to an exemplary energy consumption.
