Limited Liability Company ® Air-Cooled Heat Exchangers Purpose of ACHEs Remove heat from liquid, gas, or vapor Warm Air Hot Cooled Process Process Fluid Fluid Ambient Air ® Air-Cooled Heat Exchangers Basic Cooler Types Induced Draft  Plenum reduces solar radiation effects  Reduced hot air recirculation potential  Better airside flow distribution  Limits on air exhaust temperature. Forced Draft  Easier to maintain mechanical equipment  Easier access to clean fins  Requires less horsepower  Fans not exposed to hot exhaust air ® Air-Cooled Heat Exchangers Large Scale Applications – Refinery / Chemical / Gas Transport ® Air-Cooled Heat Exchangers Large Scale Applications – Power
