Welcome to Diecon Marine.
Confidence at Sea.
Quality. Durability. Reliability.
At Diecon Marine, we are proud to be synonymous with superior quality, long-lasting durability, and unmatched reliability.
We specialize in the design and manufacture of Diecon-branded Australian-made shell and tube heat exchangers. Leveraging our extensive engineering expertise and advanced manufacturing capabilities, we can replicate nearly any original heat exchanger component—particularly when OEM parts are obsolete or face extended lead times for import. This allows us to provide timely, high-quality alternatives that ensure your equipment operates at peak performance.

Case Studies
RiverCity Ferries
The fleet of 24 vessels were encountering overheating & performance issues with the exhaust manifold, along with difficulties in servicing, high costs, and downtime issues related to genuine Cummins heat exchangers.
Perkins Heat Exchanger
A customer approached Diecon Marine with a Perkins heat exchanger housing that had been poorly repaired by a local engineer. The existing housing needed to be replaced, but the client struggled to find a new housing or a provider capable of manufacturing one with a new tube bundle.
