EVAP TECH - CENTRAL AIR CONDITION PRE COOLING 5
INTRODUCTION:
The EVAP-TECH evaporative media have been designed to provide adiabatic cooling and
humidification for high performance applications such as evaporative coolers, air handling units and
data center cooling. These applications require the highest possible performance with minimal
maintenance and must comply with high hygiene standards.

Hydro Chill fin technology is a combination between a special fin structure and thin water-retaining
coating, designed to keep pressure drop at minimum while delivering evaporation efficiencies that

the same principle as
traditional direct
evaporative coolers,
sometimes called
swamp coolers.
However, pre coolers
do not add humidity to
the air within the
conditioned space like
evaporative coolers do.
This is because the
evaporative effect is
utilized on the outside
section of the air
conditioner to boost its
effectiveness, not
within a system that
delivers air directly
into the space.
Systems that utilize
both technologies are also available. Two stage, or direct/indirect coolers use an air-to-water heat
exchanger / pre cooler which reduces the incoming air temperature without raising the relative
humidity, then puts the incoming air through a direct evaporation stage, further reducing its
temperature.
HOW IT SAVES ENERGY:
In hot, dry conditions, evaporative pre-coolers of this type can reduce the cooling cost by 24%. It is
easy to imagine that an air conditioner will not need to run as long when the condensing section is
transferring heat more effectively. This measure works extremely well during the hottest
temperatures and so has the potential to save peak demand.
EVAPORATIVE CONDENSER PRE-COOLING UNITS:
EVAP-COOL TECH evaporative pre-cooling systems increase the efficiency and capacity of chiller
groups and dry refrigerants, offering a COP 35% increase in effectiveness. They are economical and
