Air-cooled Condensers

Remove heat from a gas stream

Air-cooled condensers cool a gaseous process stream to below its dewpoint and discharge it with most of the material in a liquid form. In this type of condenser, multiple axial flow fans supply the cooling ambient air.

Air-cooled condensers can cool various mediums, depending on the process. Most of the applications for this type of condenser are in the oil & gas, petrochemical, power generation and refrigeration industries.


How air-cooled condensers work

An air-cooled condenser uses ambient air to remove heat from the gas stream. In commercial refrigerant applications, the superheated refrigerant is cooled and condensed in a finned tube array.

One specific application is steam condensation. An air-cooled steam condenser takes low-pressure steam after a process and condenses it to allow discharge as condensate. Other materials from the process may contaminate this resulting condensate. In these instances, you can further treat the stream before releasing it to the environment.

Applications of air-cooled condensers

Most of the uses for air-cooled condensers are in the following :

In commercial refrigerant applications, the superheated refrigerant is cooled and condensed in a finned tube array.

In the petrochemical industry, most applications are for steam condensation, which presents its specific considerations. It limits the number of design solutions, and the enhancement of internal tube surfaces may not be possible. Tube material diameters and wall thicknesses may be strictly controlled. At Sterling TT, we work closely with you to discuss your specific requirements when designing any air-cooled condenser.

Design considerations

As an air-cooled condenser designer and manufacturer, we make decisions relating to:

  • fan selection,
  • mechanical builds, and
  • general specification requirements of the equipment.

These are determined by the specific application for which the condenser is required.

The specification of fans may vary significantly. We consider axial fan coverage, overall efficiency, fan tip speed and generated noise, in addition to the geometry associated with plenum arrangements. All factors must be in full compliance with the appropriate specifications and identified environmental conditions.

At Sterling Thermal Technology, we enhance the internal surface of the finned tubes to optimise the condensation of refrigerants. In conjunction with the potential for fouling and corrosion, the design pressure of the system determines the tube and external fin arrangements.
