The FlexAisle® Hot Aisle Return Plenum (HARP) configuration provides Data Centre Managers with maximum flexibility.

Unlike the Cold Aisle Corridor CAC and Hot Aisle Containment HAC configurations the HARP will support a comprehensive mix and match of cooling technology including Perimeter/Downflow, Aisle/In-Row, Rear Rack and Self Contained cooling solutions without compromising the segregation of hot and cold airflow paths.

The FlexAisle® – Hot Aisle Return Plenum – HARP configuration utilises the ceiling plenum return air path which is a standard feature in many traditional and newly built data centre facilities.

The HARP configuration delivers the improved efficiency benefits of Hot Aisle Containment with the advantage of the support for traditional downflow cooling which is still predominant in both existing and new data centre builds.

The FlexAisle® HARP configuration simply combines a demountable vertical transparent panel section with the sliding doors and top hat bracket sections used on CAC and HAC solutions.

Where there are requirements of stand alone equipment cabinets FlexAisle® offers the Adjustable Hot Air Return Duct. This system can be retrofitted or installed complete with a 1200mm deep rack, depending on the configuration of existing equipment cabinets.
