C. Evaporative Cooling and the PORT-A-COOL® unit.
The PORT-A-COOL® unit is the state-of-the-art, high efficiency, portable evaporative cooling system that
utilizes high efficiency KüüL® brand, rigid cooling media, manufactured with the patent pending “thru-cure” ™
process.The PORT-A-COOL® unit’s unique patented housing enclosure, along with the KüüL® brand high effi-
ciency cooling media, allows the unit to cool effectively in very high relative humidity conditions. Conditions that
other portable evaporative cooling devices, such as the old style “swamp coolers”, cannot approach.
The public has an initial tendency to equate the PORT-A-COOL® unit with the “swamp cooler,” types
of evaporative coolers and, in reality, the only thing that they have in common is that they are both evapora-
tive coolers, much as the 1973 model automobile and 2001 model automobile are both cars. The key to efficient
evaporative cooling is using a specially designed, high efficiency, rigid cooling media contained in a properly
designed housing to insure effective directing of the air over the water saturated media at the proper velocity.
The PORT-A-COOL® unit has incorporated all of these features and more.
As explained in PART B of this section, the effectiveness of the PORT-A-COOL® unit is best appreciated when
it is above 85˚F and below 75% relative humidity. By the time the outside temperature reaches 85˚F, the humidity is
almost always below 75%. Generally, as one goes up, the other goes down.
For actual temperature drops refer to the charts of Appendix A.
