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.  

 Q. To answer your questions below for using a cooling tower for winter use in freezing conditions, you will have to be mindful of the following:

A. 1. When cooling tower is used year round in a cold climate, the most preferred method is to not use the cold water basin of the cooling tower. This cooling tower will be installed outside and elevated to where all process water will gravity fall into a remote sump located inside a controlled atmosphere. This way, when you shut your system down (and if plumbed properly) it will leave no standing water in the cold water basin to freeze.

A. 2. We do offer immersion heaters with thermostats, that are installed into the cold water basin that will cycle on and off at specified temperatures to keep the process water in your water basin from freezing.

A. 3.  It is very common for people in the industry to use small amounts of glycol solution in your process water to help keep piping and plumbing of water basin open. This will aid in preventing freezing water. Just keep in mind, if using a glycol solution on a year round basis, that the glycol solution does not evaporate. Therefore, you will need to oversize your equipment to compensate for the glycol
