Air cooler, or air-cooled heat exchanger, is one of the most widely used equipments for petroleum refinery, petrochemical and chemical industries.
Design and manufacturing standard for air cooler:
★API 661 / ISO 13076 ( Air-cooled heat exchangers for general refinery service )
★ASME SECT.VIII Div.1
Components of an air cooler:
An air cooler consists of the primary following components

★ Fans that push or pull the ambient air
★ A mechanical driver and power transmission to run the fan
★ A plenum
★ A steel-made supporting structure
★ Header and fan maintenance platforms
★ Louvers and recirculation ducts (optional )
★ Ladder (optional )
★ Variable-frequency drive for temperature control and power (optional)
What kind of finned tubes are used to form the tube bundle?

★ "LL" type fins
★ "KL" type fins
★ "DR" type fins
★ "G" type fins
Limiting temperature range for various types of fins:
|
