Cooling and condensing of fluids in industry was conventionally done by water cooling systems. However water cooling systems are expensive from the point of view of initial cost as well as operating and maintenance costs. Air is in fact a more viable and economical media of heat transfer for achieving industrial cooling requirements. Today, air cooled heat exchangers and air cooled steam condensers are used all over the world for critical heat transfer applications in process plants, refineries and gas fields.
