Protec round, fiberglass cooling towers are available for commercial, institutional and industrial applications.

Our cooling towers are manufactured with non-corrosive materials, which result in a longer
life with minimum maintenance. Protec Cooling Towers do not rot or rust like conventional
towers because all main parts are fiberglass reinforced polyester (FRP) and rigid poly-vinyl
chloride (PVC). This eliminates the need for painting and repairs, reducing maintenance
cost and guaranteeing long dependable service.

The efficiency of the round, bottle-style Protec Cooling Tower is not only thermal, but
operational, a fact that one should seriously take into consideration when choosing a
cooling tower. Our 360 degree air intake and lower face velocity through the fill offers less
air resistance, therfore requiring less motor horsepower than other cooling towers, and
guaranteeing considerable electric energy savings.
All fan motors are water-proof and totally enclosed. (TEFC & TEAO). All fan blades are
reinforced nylon, aluminum alloy or fiberglass (FRP) with adjustable pitch. Blade pitch is
pre-set and balanced at factory.
The efficiency of a cooling tower depends upon its fill. The Protec Fill is made of rigid PVC film of flame
retardant quality with high heat exchange efficiency. This fill is suitable for operation with inlet water
temperature up to 130 degrees Fahrenheit (54°C).

The High efficiency fill reduces the motor input HP and assures uniform distribution of water, with minimum
resistance to air flow.
The inlet water pressure will rotate the sprinkler pipes to distribute the water evenly over the entire surface
of the fill, ensuring maximum performance capability. Protec’s sprinkler pipes have non-clog openings and are
corrosion resistant. Distribution headers for models up to PCT-80 are constructed of polyacetal, and for larger
models, bronze.
A water eliminator blade is located above each water distribution pipe to avoid carry-over of water.
For smaller towers, the support stand is made of fiberglass (FRP). For the larger models, all steel members
are hot dip galvanized. Stainless steel parts are also available as an option.
Note: All fastners are standard. Stainless Steel on all models.

The FRP casing and basin are guaranteed against defective materials and workmanship for a period of five
years. The rest of the components are guaranteed for a period of one year. Five years are available at an
additional cost. When returned to PROTEC with transportation prepaid, all parts found by factory inspection
to be defective will be repaired or replaced without charge, FOB our plant.

No liability will be assumed for loss or damage resulting from the misuse of our products. Also, operating
conditions should be in accordance with the name plate on the tower.
1. Pump head is obtained by adding resistance of piping, pressure drop of equipment and cooling tower.

2. Spring Vibration Isolators cannot be installed directly underneath the support legs. Please contact the
factory for installation details of your specific application.

3. Our model numbers are equivalent to tons when the selection is based on 3GPM/TON at 95°F inlet water
temperature, 85°F outlet water temperature and 75°F ambient wet bulb temperature.

4. For motors 7.5 HP and above, installation of stardelta or soft start starter is recommended.


6. The cooling tower must be located at such distance and direction to avoid the possibility of contaminated
tower discharge air being drawn into building fresh air intake ducts. It is recommended to consult with a
Licensed Professional Engineer to certify the location of the cooling tower.

7. Water Treatment must be supplied and/or applied by a professional in the field in order to avoid fill
damage. It is the user’s/owner’s responsibility to treat the water in order to stop biological contaminations
and avoid, among other bacterium, the Legionnaire’s Disease.

For inquiries about PROTEC Cooling Towers, please contact our local representative or our engineering
department and specify the following conditions:

      a) circulating water flow
      b) circulating water inlet temperature
      c) circulating water outlet temperature
      d) ambient wet bulb temperature
      e) power source-voltage / phase / frequency
The capacities shown in this chart are for guidance purpose only and are the maximum each model can
handle when 3 GPM of water per ton enter 95°F and leave 85°F. Please refer to the wet bulb of the area
where the cooling tower will operate.

For other values, please consult our local representative or our engineering department.
