Cleanroom air flow, temperature and relative humidity control, and particulate concentration demand low level air returns. Cleanroom low level returns facilitate the removal of particulate through correctly engineered air change rates, non-stratification of air flow patterns, and pre-filtration of larger particulates.
Hexakore Techno Build Cleanroom Systems low level return air plenums offer a fully insulated horizontal plenum area which reduces mechanical HVAC air distribution systems cost. Easily installed on either the interior or exterior of the cleanroom they can be positioned to accommodate cleanroom process equipment requirements while assuring correct air flow patterns throughout the cleanroom environment.
Hexakore Techno Build low level return sizes and locations are determined by our mechanical engineers to allow for process equipment location, air change rates, and HEPA filter ceiling module locations. They can return air flow back to the air handling systems for treatment or in the case of a pressurized plenum design allow it to recirculate though the HEPA filtration modules to maintain cleanroom particulate levels.
