SSAU Supply secondary
air unit
When only supply air is required for the ventilation system, openings in the building’s envelope are used for extraction. The area is positively pressurised, and a percentage of secondary air is recirculated through this unit and back into the area served. This unit is equipped with two dampers for fresh air intake and secondary air for recirculation. These can be adjusted to control the mix of fresh and secondary air depending on the needs of your site. These units are key to conserving energy in industrial sites, healthcare and pharmaceutical facilities, warehouses, and distribution and data centres. They lower the energy consumption of these sites, reduce need for investment in heat generation and distribution systems and mitigate the overall harm to the environment.
