Overview:

forced draft This arrangement, where air is pushed across the bundle, meets API 661 “forced draft”.
Advantages:

  • Fans are easily accessible
  • Lower operating costs
  • Better thermal performance of the heat exchanger
induced draft This arrangement, where air is pulled through the bundle, meets API 661 “induced draft”.
Advantages:

  • Provides more uniform air distribution across the bundle
  • Protection from adverse weather (direct sun-shine, hail, heavy rain, snow)
removable cover-plate header This header design, with a flanged cover-plate, meets API 661 “removable cover-plate header”.
Use:

  • Highly soiled fluids with frequent tube cleaning intervals on the inside of the tubes.
plug header

plugs

This header design, with a shoulder plug opposite to each tube end, meets API 661 “plug header”.
Use:

  • Fluids under high pressure on the tube side (e.g. gases). If the plug has been removed, the tubes behind it can be cleaned, re-rolled or closed.
axial fan The axial fan with driver

  • optionally available ex-proof along with ex-certification (e.g. ATEX, …)
  • driven by IEC or NEMA standard motors
    • Direct drive
    • Geared motor
    • Motor with belt drive (V-belt drive, variable speed drive)
bonnet header with a half pipe end construction The bonnet header with a half pipe end construction.
Use:
With clean products on the inside of the tube and/or with a low leakage requirement.
