Oil and Gas Industry

Water shortage and increasing costs, along with the recent concerns about water pollution and cooling tower plumes, have greatly reduced industry’s use of water cooled heat exchangers. As a direct result a large proportion of the process cooling in Refineries ,Chemical plants and Power plants takes place in Air Cooled heat Exchangers (ACHE). These are also called Air Fin Coolers (AFC) or Fin Fan Coolers (FFC) in the Refinery sector and as Air Cooled Condenser in the Power sector.

The design of ACHE is more complex than for a Shell and Tube Heat Exchanger, as there are many more components and variables.

Air fin coolers/ Fin fan coolers are mainly finned tube heat exchangers, in which the process fluid is flowing inside the tubes and the ambient air through fins acts as cooling medium. The main application is to Cooling or condensing of hydrocarbon fluid in the Petroleum, Petrochemical and Natural gas industry.

We provide comprehensive heat transfer solutions for oil and gas industry, which includes following sectors :

  • Petroleum refineries
  • Oil extraction wells
  • Chemical Manufacturing
  • Fertilizer Manufacturing
  • Petrochemicals
  • Gas Booster stations
  • Compressor Coolers
  • CNG Stations
  • Oil Coolers with inserts
