Delta Cooling Towers, Inc. designed the first engineered plastic (polyethylene) cooling tower in 1971 (Company History). Since then we have improved and expanded "The Most Durable Corrosion-Proof Cooling Towers Available" to a full line of factory assembled cooling towers for any application.

Cooling Towers for critical Service Applications that cannot afford maintenance costs and downtime of Galvanized Sheet Metal Towers. Industry leading 15 Year Warranty on unitarily molded cooling tower casing. Manufacturing engineered plastic cooling towers since 1971 in our fully integrated manufacturing facility for applications including:

Why Delta Cooling Towers are the Industry's Best

 
  1. Delta Cooling Towers are made from a CORROSION PROOF engineered plastic. The cooling tower shell will never rust, flake, chip, peel or ever need painting or protective coatings applied. Delta believes its towers are the future of the industry. Metal towers do not have the long-term corrosion protection advantages for outdoor usage. The galvanizing or other metal treatments only delay the corrosion of the underlying, often thin gauge sheet metal.


  2. Delta manufactures a totally SEAMLESS cooling tower. Delta towers are the only large packaged cooling towers in the industry that have a "one-piece" shell. This means there are no seams, panels, rivets, or hundreds of fasteners to fail or compromise the performance or integrity of the product.


  3. Delta stands behind its products with the best warranty in the industry. Delta provides a 15 YEAR WARRANTY on the cooling towers structural shell. In addition, Delta’s cooling tower motors have a 5 year warranty.


  4. Delta Cooling Towers are LOW MAINTENANCE by design. Delta has carefully designed its products to have minimal maintenance issues. Other manufacturers of cooling towers have much more complicated designs to achieve the same performance. This includes many more parts - which are more potential maintenance and upkeep issues. One example is Delta’s Direct Drive Fan Systems which do not require the maintenance of other towers. On Delta towers there are no gear reducers, couplings, additional shafts, or extra bearings to maintain.


  5. Delta prides itself on exceptional CUSTOMER SERVICE. Our "Can-Do" mindset allows us to meet or exceed any customer’s cooling tower requirements. We offer many product options and can provide any accessories associated with cooling towers.

Principles of Cooling Towers

 
All cooling towers operate on the principle of removing heat from water by evaporating a small portion of the water that is recirculated through the unit. The heat that is removed is called the latent heat of vaporization. Each one pound of water that is evaporated removes approximately 1,000 BTU's in the form of latent heat.

COOLING TOWER TERMS AND DEFINITIONS

BTU (British Thermal Unit)
A BTU is the heat energy required to raise the temperature of one pound of water one degree Fahrenheit in the range from 32° F to 212° F
Cooling Range
The difference in temperature between the hot water entering the tower and the cold water leaving the tower is the cooling range.
Approach
The difference between the temperature of the cold water leaving the tower and the wet- bulb temperature of the air is known as the approach. Establishment of the approach fixes the operating temperature of the tower and is a most important parameter in determining both tower size and cost.
Drift
The water entrained in the air flow and discharged to the atmosphere. Drift loss does not include water lost by evaporation. Proper tower design can minimize drift loss.
Heat Load
The amount of heat to be removed from the circulating water within the tower. Heat load is equal to water circulation rate (gpm) times the cooling range times 500 and is expressed in BTU/hr. Heat load is also an important parameter in determining tower size and cost.
Ton
An evaporative cooling ton is 15,000 BTU's per hour.
Wet-Bulb Temperature
The lowest temperature that water theoretically can reach by evaporation. Wet-Bulb temperature is an extremely important parameter in tower selection and design and should be measured by a psychrometer
Pumping Head
The pressure required to pump the water from the tower basin, through the entire system and return to the top of the tower.
Makeup
The amount of water required to replace normal losses caused by bleed off, drift, and evaporation.
Bleed Off
The circulating water in the tower which is discharged to waste to help keep the dissolved solids concentration of the water below a maximum allowable limit. As a result of evaporation, dissolved solids concentration will continually increase unless reduced by bleed off.
