CELdek® EVAPORATIVE MEDIA
The Evaporative Cooler utilizes high effi ciency
CELdek® media. CELdek® is made from a special
cellulose paper, impregnated with insoluble anti-
rot salts and rigidifying saturants. The cross fl uted
design of the pads induces highly-turbulent mixing
of air and water for optimum heat and moisture
transfer. The evaporative coolers are available
with standard 8 or optional 12 inch media which
produce high effi ciency and high face velocities,
along with a 2" distribution pad to disperse the
water evenly over the pads.
