Custom and TEMA Type Shell & Tube Heat Exchangers

Standard or Pre-Engineered Shell and Tube Heat Exchangers are often the most cost-effective solution for a heat transfer process but they do not fit all applications. Processes that require, special materials, high pressure unique thermal designs or special codes wil require a custom design. Delta T Heat Exchangers can provide exchangers from 3″ diameter to 80″ diameter to TEMA standards, ASME, API and many other codes in many materials. If you know your performance requirements, you can contact us by requesting a quote.
