Petrochemicals


Zungu-Elgin has always been at the forefront of Heat Exchanger technology. We have a reputation for our ability to manufacture high standard, high performance heat exchangers to all specifications. One of our key achievements has been the manufacture of the largest Texas Rower rod baffle exchanger in the world. Our shell and tube heat exchangers are designed and manufactured to ASME and TEMA standards, while our pressure vessels meet ASME and British standards.
