DRY Cooling Tower

An Indirect Dry Cooling Tower is a system that uses two separate fluid loops to reject heat. The process fluid is first cooled by water in a conventional heat exchanger, and then that water is itself cooled by air in a dry cooling tower. The key concept is the word “indirect”—the primary hot fluid (e.g.,...

A Direct Dry Cooling Tower is a system where the primary process fluid (e.g., the steam from a power plant turbine) is sent directly to the large air-cooled heat exchangers (the finned tubes) in the tower. There is no intermediate heat exchanger or water loop. Think of it as connecting your car’s engine directly...

Application of Dry Cooling Tower Dry cooling towers are the technology of choice when water is more valuable than energy or when environmental regulations prohibit water use or vapor plumes.

Types of Dry Cooling Towers There are two main configurations:

A Dry Cooling Tower is a heat rejection device that cools a working fluid (almost always water) without direct contact with the air and without the process of evaporation. Instead, it operates solely through sensible heat transfer, where heat moves from the hot fluid to the cooler air through a solid barrier (metal fins). This...

A Dry Fluid Cooler works on the principle of sensible heat transfer. It uses ambient air to cool a process fluid without the fluid and air ever coming into direct contact. The heat is rejected solely through the transfer of thermal energy (sensible heat) from the hot fluid to the cooler air across a metal barrier. […]

A Dry Fluid Cooler (also known as a Dry Cooler or Air Cooled Heat Exchanger) is a device that cools a process fluid (most commonly water or a water-glycol mixture) using ambient air.
