Spiral & Welded-Bloc Heat Exchangers

Specialty Heat Exchangers

Striving for excellence in all we do, NHE cleans, reconditions, and tests all types of specialty heat exchangers, including Spiral and Welded-Bloc.

The National Heat Exchange cleaning process allows us to completely clean all internal passages, regardless of the flow pattern. After thorough cleaning, our experienced in-house technicians can easily locate any leaks with bubble and/or dye-penetrant testing. With direct access to OEM and non OEM replacement parts for all types of coolers, any needed repairs can be made efficiently and effectively.
