Conguraon - Cooling and best installaon pracce
The EDGE-3 can achieve up to 12kW of heat removal. But in order to achieve these gures it is paramount that ‘best installaon
pracce’ is adopted. Understanding the airow characteriscs of the EDGE-3 design is key.
Airow characteriscs
The key dierence between most 19” soundproof cabinets is the poor segregaon between cold air entering into the cabinet and
the IT equipment space – failure to deal with this results in hot spots and general heat recirculaon issues.
The EDGE-3 deals with the
problem by creang three
separate zones – the rst zone is
the ‘patent pending’ double pass
wardrobe front doors, ambient air
passes through the full height of
the doors and into the second
zone.
This feature is of key importance
as this allows a uniform ow of
ambient cool air to be available at
any ‘U’ posion within the cabinet
– so no equipment needs be
starved of cool air. It is worth
nong that this vercal space
should be kept clear and that all
cabling should be kept managed
against the inll panels provided,
using jumper rings or cable
trunking .
The result of best pracce sealing - no hot air recirculaon
The second zone is the IT equip-
ment space and sealing between
the rst and second zone is crical;
the EDGE-3 cabinet comes as
standard with foam inlls which
covers the periphery of the 19”
area see Figs 2
and 4.
Cabling can pass through this area
from front to rear but maintaining
the seal’s integrity is very im-
portant. In addion to the periph-
eral area the 19” aperture also
needs to be treated in the same
way – completely sealed. Unfortu-
nately not all equipment comes in
the standard 19” format, for this
reason there are a number of solu-
ons designed to assist in this pro-
cess - see Fig 2 and 5.

= Keep these areas clear of obstrucon to air airow
The patent pending air inlet wardrobe doors
enable the required volume of air to uniformly
ow over the full height of the ‘U’ (usable)
space on both sides of the cabinet, thus
ensuring that all the enclosed IT equipment
receive the necessary amount of air.
NB The acve rear door on the 12U model exhausts hot air to the base of the door and not the top as in other height models
