Various types of high-fin tubing are available, including: • Integrally finned (K-fin) • Bimetallic (E-fin) • Tension-wound fin (L-fin or I-fin) • Embedded fin (G-fin) • Brazed fin
Common to all air cooled heat exchangers is the tube, through which the process fluid flows.To compensate for the poor heat transfer properties of air, which flows across the outside of the tube, and to reduce the overall dimensions of the heat exchanger, external fins are added to the outside of the tube. A wide […]
Advantages of Forced Draft Slightly lower horsepower since the fan is in cold air. (Horsepower varies directlyas the absolute temperature.) Better accessibility of fans and upper bearings for maintenance. Easily adaptable for warm air recirculation for cold climates. Better accessibility of bundles for replacement. ...
Advantages of Induced Draft of intake, or about 1500 ft/min. Increased capacity in the event of fan failure, since the natural draft stack effect is much greater with induced draft
