FREE FORM AISLE CONTAINMENT

Complete Free Form Aisle Design Principles

• End to end edge beam:

The edge beam which supports the overhead Containment panels  above the Aisle is a full “end to end” beam, not individually  dedicated to any one Rack. It is substantially fixed at each end to  the Aisle end frame and Aisle end rack.

• Moveable, intermediate support jacks:

To adjust the edge beam, taking out any slight downward deflection, simple small support jacks can be positioned anywhere along the edge beam. Small support jacks can be positioned wherever a convenient surface exists, on a rack roof, easily fitting in clear space between glands, vents etc.

• Jack removal/replacement

Intermediate support jacks can be quickly disengaged to allow removal of the required Racks. The stiff edge beam design enables the support beam to span vacant Rack-pockets.  Full height panels provisionally close off vacant Rack pockets until Racks  are introduced.

• Spanning, rack mounted cable raceway

The Cannon cable raceway is designed to span vacant  Rack-pockets and ensure continued cabling when vacant rack space is blanked off.

• Vertical closure panels

Adjustable closure panel(s) cover and seal the small vertical space between the edge beam and the installed Rack roof.

• Extended vertical closure panels

Where an installation is fed with down flow cold air from the  ceiling, vertical closure panels can be of a type which extend  upwards to meet and seal the ceiling.  This option provided separation of the Cold Aisle & Hot Aisle air flow.

• All Cannon Aisle Containment virtues are retained

All of the usual Active or Passive Aisle Containment features are maintained with the Cannon Free Form Aisle Containment system.

• Aisle upgrade of old installations

Where old Rack installations exist, even with mixed Rack types and sizes the Cannon Free Form Aisle Containment system provides a cost effective retrofit Aisle Containment solution.

• It is good practice for a “Complete Free Form Aisle” to restrict any open span in the row to three rack widths e.g. 3 x 800mm cabinets = 2400mm (7-11”) or four rack widths e.g. 4 x 600mm cabinets = 2400mm (7-11”) – With “Basic Free Form Aisles” we recommend an open span of no more than 1600mm with each end of aisles including a minimum of 1 cabinet per aisle.
