Cooling and best installation practice
The EDGE
-
3 can achieve up to 12kW of heat removal. But in order to achieve these figures it is paramount that
‘
best installation
practice
’
is adopted. Understanding the airflow characteristics of the EDGE
-
3 design is key.
Airflow characteristics
The key difference between most
19”
soundproof cabinets is the poor segregation between cold air entering into the cabinet and
the IT equipment space –
failure to deal with this results in hot spots and general heat recirculation issues.
The EDGE
-
3 deals with the
problem by creating three
separate zones –
the first 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 flow of
ambient cool air to be available at
any
‘
U
’
position within the cabinet
–
so no equipment needs be
starved of cool air. It is worth
noting that this vertical space
should be kept clear and that all
cabling should be kept managed
against the infill panels provided,
using jumper rings or cable
trunking .
The result of best practice sealing
-
no hot air recirculation
The second zone is the IT equip-
ment space and sealing between
the first and second zone is critical;
the EDGE
-
3 cabinet comes as
standard with foam infills 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 addition 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-
tions designed to assist in this pro-
cess
-
see Fig 2 and 5.

= Keep these areas clear of obstruction to air airflow
The patent pending air inlet wardrobe doors
enable the required volume of air to uniformly
flow 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 active rear door on the 12U model exhausts hot air to the base of the door and not the top as in other height models
