Frequently Asked Questions
Q. How are you able to provide a 20 year warranty on the FRP? That's longer than any other manufacturer warranty in the industry today.
A. Our FRP (fiberglass reinforced polyester) is mixed with a gel coating that strengthens and protects it from the UV (ultraviolet) light rays in the ozone. This provides a higher resistance to rot and decay to all FRP portions of the cooling towers in extreme climate environments.
Q. What makes CTS more energy efficient than other cooling tower manufacturers?
A. CTS' FRP counter-flow induced draft cooling towers have a 360 degree air intake within the center of the cooling tower. This allows more fresh air supply than a conventional, cross-flow or counter-flow cooling tower- which only draw air from two sides of the system. This allows for our counter-flow induced draft cooling towers to have less fan motor horsepower per ton when compared to a conventional cooling tower.
Q. How do I size my cooling tower?
A. There are different ways to size a cooling tower. The most efficient way is to provide us with a design condition to include entering and leaving water temperatures, total flow rate and wet bulb temperature or location (city, state & country) of where the cooling tower will be put to use.
If you only need to expel a BTU heat load, our model T-2 counter-flow induced draft cooling towers expel 15,000 BTU/hr per ton on 60Hz. Ex. If you need to expel 45,000 BTU, you would need our model T-23. 45,000 / 15,000 = 3 Nominal Tons
*If cooling tower is hooked up to 50Hz, it will only expel 12,000 BTU/hr per ton. Ex. If you need to expel 36,000 BTU, you would need our model T-23. 36,000 / 12,000 = 3 Nominal Tons
Q. When should we use a single cell system vs. a multi-cell system?
A. A single cell system is used when the thermal performance requirements do not fluctuate throughout the year. CTS recommends using a multi-cell system in situations where the thermal performance requirements vary throughout the year. This allows one cooling tower to be valved off and be used independently which results in energy savings and also extends the life of the equipment.
Q. What is the difference between a closed loop systems (fluid cooling tower) and an open cooling tower?
A. A closed loop system, or fluid cooling tower, is used for process cooling to keep all fluids contained from any outside elements. An open cooling tower does have an evaporation process and fresh water make up through out the system that brings outside elements into the water supply.
Q. When should I consider a high temperature cooling tower?
A. Our standard counter-flow induced draft fiberglass reinforced polyester cooling towers can withstand a maximum temperature of 130 degree Fahrenheit. All temperatures above 130 degrees Fahrenheit, needs to be provided to the sales office so we can select and guarantee a cooling tower that will meet your high temperature requirements.
