Since Spiral Heat Exchanger
Denoted from its name, the flow paths of the Spiral heat exchanger travels through a pair of concentric spiral channels. A well designed unit can be self cleaning creating a "scrubbing effect". Therefore, the Spiral heat exchanger is very suited to fouling process fluids, slurries and sludge. It can also present a compact solution capable of very low pressure drop requirements for evaporation duties.
The FRHE Spiral Heat Exchanger is highly suitable for non-newtonian, viscous and fibrous liquids, suspensions, slurries, sludges and also vapour with inert gases.
