Material combinations:

Overview:

	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
	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)
	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.
	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.
	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)
	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.
