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.
