Description

These are demountable corrugated tube heat exchangers formed by two concentric tubes and are especially useful for treating slurries (fluids which contain significant amounts of fibres or suspended particles) and particulate fluids (such as fruit dices). Characteristics XLG®SD-Series Demountable Tube-in-Tube heat exchangers are constructed from stainless steel and are formed by having two concentric tubes, the inner tube being demountable from the outer tube. The fluid to be treated is normally passed through the corrugated inner tube and the service fluid, providing the source of cooling or heating, passes through the annulus formed by the two tubes. This range is formed from units of different tube diameters chosen according to the flow rates of the working fluids. Corrugated tubes are used in order to significantly enhance the rate of heat transfer and thus minimise the size of heat exchanger required. The fluid circulating through the inner tube (the product) and the fluid circulating through the annulus formed by the two tubes (the service fluid) are completely isolated from one another and cannot interleak, the heat being transferred via the tube wall of the inner tube. Leakage of the service fluid to atmosphere is prevented by a pair of elastomeric O ring seals at each end of the tube. One end of the inner tube is fixed to the outer tube assembly while the other end is free to expand and contract with the change of temperatures occurring in service, thus avoiding the potentially damaging stresses that occur in other types of fully welded heat exchangers.
