Cool Edge
has been combining the experience of over 15 years in the business with
creative ideas to lead the industry in evaporative cooling systems. Evaportation
is one of the simplist and oldest methods of cooling air. With our continued
technological advances, the simple principles of evaporative cooling remain
the most cost-efficient method for environmental temperature control.
Direct evaporative systems rely entirely on the evaporation or water for
their cooling process. With that in mind, we have paid particular attention
to the design of our pre-coolers from the special engineered casing with
superior reservoir recycling systems or single pass systems to the specialized
media and overall controls.

Direct
evaporative systems rely entirely on the evaporation of water for their
cooling process. Water is supplied to the top of the media and allowed
to trickle down. As the water is soaking in and spreading over the highly
absorbant surface of the CELdek® media, air is pulled in through the
fluted openings by the existing unit's fan. This induces the turbulent
mixing of air and water for optimum heat transfer. The evaporation of
the water removes heat from the inlet air, which results in dropping air
temperatures. This drop in air temperature before it flows through the
condenser coils increases the operating efficiency of the unit. Increased
efficiency leads to energy savings and extending the unit's life. Pre-coolers
can be used in applications such as: air-conditioning and refrigeration
systems, chillers and fresh air makeup systems. With the installation
of a fan, they can also be used in green houses and to cool livestock
and poultry and other applications where efficient cooling is needed.
Pre-coolers are low maintenance and will usually pay for themselves by
increased cooling efficiency, resulting in extending the life of the unit
as well as energy savings. Evaporate systems are operated in ambients
above 75 degrees F dry bulb.
