Cost saving drying of water-cooled cables
September 1st 2011 In addition to standard wires
and multicores, wire and
cable manufacturer, Concept
Cables can tailor products to
specific needs.
A recent challenge was to
find a way to remove the
residual moisture film from
water-cooled insulated cable
products during production.
ACI's new 'LINE-Dry' System
offered a solution. ACI
estimates that, compared to
the compressed air system
previously used, the blower-
Carbolite did not need an
afterburner; a 600 x 1200mm
Inconel 601 retort was used
to contain the nitrogen/
hydrogen atmosphere.
Inconel-coated catch
trays were added to the
retort to capture any
process
material that
might fall
from the
load. The
nitrogen/
hydrogen
reducing gas was premixed
and below the
explosive limits for
hydrogen.
As uniform heating of the
load was critical, a 3-zone
control system compatible
with NADCAP 2750 D, Class
2, was installed.
powered wire/cable drying
system can give up to a 10-
fold reduction in energy costs
and Paul Randall of Concept
Cables, says product quality
has improved.
The ACI system can
handle products to 25mm
dia at speeds of 500m/min.
The blower is an ACI variable
speed multi-stage unit
controlled via a speed
controller. Two versions are
available, one with the dryer
heads enclosed to contain
displaced moisture; the other
is an open unit. Air is
delivered at up to 2.8psi
(80in. SWG) at speeds of
8800m/min at 80°C. More articles from Air Control Industries Ltd: |
