32004 PORT-A-COOL®Unit Electric Models
The hotter the day, the drier the air becomes, and the more cooling that can take place
through the evaporation of water. This means that when the day gets hot enough to require cooling,
the relative humidity will be much lower than in the morning and will allow an evaporative cooling
device to work more effectively.
Since any evaporative cooling device must evaporate water to achieve cooling, more water
vapor is put into the air. As the ambient relative humidity increases, it becomes more difficult to put
moisture into the air. The efficiency of any evaporative cooling device is directly related to its ability
to evaporate water (cooling the air) at a given relative humidity. A unit with low efficiency will cool
only at low relative humidity levels, while a unit with high efficiency can achieve effective cooling at
much higher humidity levels.
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 efficiency 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 cool-
er,”types of evaporative coolers and, in reality, the only thing that they have in common is that they
are both evaporative coolers, much as the 1973 model automobile and 2003 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 appre-
ciated when it is above 85˚F and below 75% relative humidity. By the time the outside temperature reach-
es 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.
II. SETUP
A. Unpacking the PORT-A-COOL®unit.
The standard 24”,36”and 48”electric models of the PORT-A-COOL®unit are shipped com-
pletely assembled and sitting on a plastic or wooden pallet with a large cover box strapped over the
PORT-A-COOL®unit. It is a simple matter to cut the straps and remove the box by lifting it over
the PORT-A-COOL®unit. Remove the protective plastic dust cover to expose the PORT-A-COOL®
unit. The 16”model PORT-A-COOL®units are shipped in an enclosed corrugated box and need
only be removed from the box.
