An air-cooled heat exchanger transfers heat from process fluid to the ambient air across fin tubes to remove heat. These are regarded as an alternative to cooling towers and shell as they do not need an auxiliary water supply. They are used only when temperate is more than 20 degrees Fahrenheit.
Although they are considered a green solution because no water is lost or treated with chemicals, they are expensive as compared to the water-cooled exchanger. The use of Air Cooled Condensers for power stations is increasing rapidly as their process systems generate a lot of heat and the power stations need to eliminate it.
These air-cooled exchangers consist of a finned tube bundle. There are rectangular box headers at both ends of the tube. One or more fans provide cool air. Usually, air is blown in an upward direction through the horizontal tube bundle. The spacing between the fans and bundles is bounded by a plenum checker that provides direction to the air. The fans might be induced or forced draft, this depends on the fact if the air is pulled or pushed through the tube bundle.
Hamon d’ hondt Saudi, one of the manufacturers of Fin tube Air Cooled Heat Exchangers offers innovative, effective and flexible solutions in the area. The latest technology used by them transfers heat from a process fluid to the ambient air across tubes to remove heat.
An air-cooled heat exchanger is an ideal choice because cooling systems pose large economic drawbacks. Air cooled heat exchangers are beneficial as they can be set up to utilize a variety of arrangements.
The following factors prove why Fin tube Air Cooled Heat Exchanger is important-
- Reduced wastage of water
One of the most important advantages of an air-cooled heat exchanger is that no water-based methods are used and hence, water is saved. No water usage means zero installation costs of coolants, less construction, no added costs associated with the treatment of water, etc. This also saves the water from getting polluted.
- Flexibility and Lower Maintenance
Fin tube Air Cooled Heat Exchanger can easily be accommodated and located. The heat exchangers don’t require any reconstruction to fit into the industry if it had once established. Water cooled heat exchanger can require frequent maintenance because of its association with water, but air-cooled heat exchangers require less maintenance. They need less attention and don’t need to be cleaned regularly. This saves efforts as well as time.
- Easy Temperature Control
Air cooled heat exchangers don’t take a toll on temperate rather makes it controlling easy. Changing the temperature in a multiple fan installation is quite easy. Shutters, pitch fan blades or variable speed drives can be adjusted to change the temperature.
