EXTERNAL FOULING FACTORSEXTERNAL FOULING FACTORS

First of all we adopt higher fouling coefficients than those usually shown in standard specifications, different for each heat exchangers and taking their different behaviour into account when in operation.

In our experience we prefer to favour reliability, lifetime and safety factors in this type of plant, rather than go for a tighter dimension or a "tempting" price.

Fouling is limited, even in the design stage, by adopting a completely vertical tube configuration, that greatly reduces the possibility of dust settlement.
