Fin Type Typical Materials Key Advantage Key Disadvantage Common Application Wrapped (L-Fin) Aluminum on CS Cost-effective, versatile Potential corrosion at fin root General purpose, oil & gas Embedded (G-Fin) Aluminum on CS Excellent bond, reliable More expensive than L-fin High-vibration, reliable service Extruded (Integral) Copper, Aluminum...

Types of Fin material used in Air Cooled Heat Exchanger? 1. Wrapped Fins (L-Fins) This is one of the most common and cost-effective types. 2. Embedded Fins (G-Fins or I-Fins) Similar to L-fins but with a different fin foot profile. 3. Extruded Fins (Integral Fins) This type is monolithic, meaning the fin and tube are […]

Common Applications of forced draft air cooled heat exchanger Forced Draft coolers are often selected for specific applications where their advantages are critical:

Forced Draft vs. Induced Draft: A Direct Comparison Feature Forced Draft (FD) Induced Draft (ID) Fan Location Below the bundle On top of the bundle Airflow Mechanism Pushes air across tubes Pulls air across tubes Air Pressure in Bundle Positive pressure Negative pressure (vacuum) Air Distribution Less even, can have dead zones Excellent and even...

Forced Draft Air-Cooled Heat Exchanger (FD Fan ACE). This is the other primary design, alongside the Induced Draft, for using air to cool process fluids. The core distinction is in its fundamental operating principle. The Core Concept: “Forced Draft” “Forced Draft” means the fan is located at the base of the unit, below...
