New input case for you: This technology module contains a brief introductory description to the exchanger type above, followed by information on construction, construction materials, operating limitsand principal applications. Where appropriate, a comparison is made with conventionalshell and tube heat exchangers to emphasise size and weight reductions that can beachieved by using compact heat exchangers.The Module 3 series present further information applicable to all technologies, such asgeneral advantages and limitations of compact exchanger designs, common applications,fouling and how to minimise it, energy efficiency. heat transfer enhancement, exchangerselection, specification and operation, process intensification and software programmes.
Output:
Positive
