Direct Outside Air Free Cooling Solutions for Data Centre

Notes: 1. Down-flow units are with return air inlet at high level. With inlet at mid level, they are the same (reduced) width as the up-flow versions. 2. Down-flow unit plinths are supplied separately and can be manufactured to suit varying floor void depths. 3. Full sound spectrum data for each fan is available on request for noise critical installations.
