We began constructing carbon steel finned tube heat exchangers in the late 1980’s, for our high temperature kilns, as the timber drying market evolved, there was a shift to lower kiln air temperatures and carbon steels gave way to stainless steels. Since then we have developed considerable expertise and market penetration for finned tube heat exchangers, supplying coils not only for kilns, but for heat plant preheat, process heat recovery and the exacting requirements of the dairy industry.

We have built finned tube heat exchangers ranging from 100KW to over 25MW capacity using our own in-house designed software refined to allow the design of purpose built coils to suit a customer’s requirements, for high pressure hot water, high and low pressure steam and thermal oil, and a variety of air side gases. Designs take into account the specific requirements of the hot and cold process streams. Design also involves the careful selection of heater coil materials, relevant welding procedures, allowances for thermal expansion, provision of coil support, and testing and inspection requirements.

All heat exchangers are manufactured from stainless or carbon steel base tube. We can provide advice as to the most suitable base tube and fin type for your application.

All heater coils are manufactured at our workshops to Australasian or ASME codes, and the requirements of the OSH Code of Practice. We supply full documentation with each coil, and weld maps if required, third party inspection (including full internal endoscopic inspection of welds) is provided where necessary.
