INDUSTRIAL EVAPORATIVE PRECOOLERS
Industrial Pre-Cooler Installation on Gas Turbine Intake
INTRODUCTION TO SOME TYPICAL PRE-COOLER
APPLICATIONS:
The performance of most, if not all air cooled heat
generating equipment decreases inversely
with temperature rise.
A common example of this is the air cooled
condenser coils of air
conditioners. This is illustrated in the following example of a Typical
Trane Chiller Model
RTAC250STD, commonly referred to as a 240 Ton Chiller.

Industrial Evaporative
Pre-coolers when properly designed and installed presents to the condenser coils
(or equipment) cooler air temperatures that allows the equipment to operate at
or near their optimum design level.
Following are some examples of custom Pre-cooler installation plans. Each
installation requires consideration for the existing conditions of space,
operational characteristics of the equipment, climate, ease of access for
maintenance, etc.
