Our mission is to provide superior products and services in the field of cooling systems with the best performing, proven and innovative solutions.

Principal Of Cooling Towers

All cooling towers operate on the principle of removing heat form water by evaporating a small porting of 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 320F to 2120F

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.

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.
