Considering spiral heat exchanger for fouling applications, it is best.
That compact heat exchanger(Spiral type) bring high efficiency and minimum maintenance.
The capital cost for spiral type it is normally higher than shell and tube type on the same heat transfer area.
However, due to the Spiral type has high efficiency, it requires a smaller heat transfer area. It means that finally the capital cost slightly higher than shell and tube type.
In addition to that, in case of fouling applications, operational cost for spiral type is lower than shell and tube type. It means that long time operation and minimum down time. And, the risk of unscheduled maintenance is normally reduced.
Finally, total cost which is capital and operation, the SPIRAL will be best choice.
