Macleay Island, South East Queensland – A D9050-B 3-cylinder Kubota marine engine suffers significant corrosion to the heat exchanger.
The cause? The heat exchanger had never been serviced.
It is recommended that marine heat exchangers are serviced every 6 to 9 months. As our client found out, not doing so can result in a lengthy and costly restoration.
Luckily for the owners, we, at Redback Diecon, were able to remove the seized bundle with the help of a few tools and specialised chemicals, refurbishing their old unit and delivering huge savings! We initiated our “Priority Case Action Policy” as the customer needed the repair finished and put back in the water within 72 hours.
Redback Diecon began the restoration on the housing by welding new end caps and hose fittings, and replacing the filler neck radiator cap. We then manufactured a new tube bundle using the original drawings. The housing and tube was then tested using our testing rigs at 25 PSI for 5 minutes to ensure there were no leaks around the new cap welds.
The housing passed the testing, and then went on to be painted with a red oxide undercoat.
After 3 days of restoration, the client was able to pick up the repaired heat exchanger and was delighted with the results. “I am pleased with the quality and service that Redback Diecon have provided for us.”
