Rigid Tabulators

Concept Engineering, manufacturer of heat transfer equipment, offers Rigid Tabulators. The rigid centre rod wire turbulators allow a much higher wire loop density. Here a rigid central rod has loops (oval shaped) soldered to it. The turbulator is then soldered to the tube walls or end brazed inside the tubes giving a strong fit. Advantages: a very high concentration of loops; the loops if tube soldered, give very good bonding and heat transfer by conduction in addition to turbulation; can withstand high pressure; and can be offered in carbon steel, stainless steel 304/316 and copper. Disadvantages: higher cost; once installed, cannot be removed; as turbulators brazed/soldered in tubes; depending on grade specified, solder will melt at 180/290°C; and hence unsuitable at higher temperatures. Concept Engineering specialises in designing and making wire wound fin tubes and turbulators of all types. It can design heat exchangers that will use these tubes and turbulators, but its capacity to design and manufacture fin tubes and turbulators exceeds the capacity to make heat exchangers. The company prefers to work in partnership with customers’ world wide where it provides the design and material support, while they do the fabrication of heat exchangers. To assist fabricators who wish to add exchangers to their range, it also provides precision CNC drilling of tube sheets and baffles for local assembly; and designs the exchanger and supplies all the required components for local assembly. In the past this has included bought out components like tube expanders, dished ends also.
