I can thank you and your team for the amazing support and agility to meet our requests at short notice.   Well done and we are looking forward to getting Thaiyak grills installed and set to work.

I would like to pass on my appreciation for the support and design of our engine room ventilation system for our vessel. 


When ever we had a question we could ring David and he would always have a answer. We received everything thing yesterday, and when I mean everything it was down to mounting nuts bolts screws and the correct drill bits and taps required for the whole install. Installing the 1 damper and 2 fan units and VSD units made it a breeze. 


On behalf of Taranto marine and Southern Cloud we would like to say thank you and looking forward to working with you in the future.

Mate just a quick email with some photos of the finished project on Reelistic in Townsville. Thanks again for the great service, support and assistance throughout the whole project. Owner Cliff McCulloch of Northern Conquest Charters in Townsville is stoked with the job and says she is performing great with the increased air flow and no water ingress at all.


As for my side in the job we were blown away with the professionalism and quality from the first phone call through to the installation package included with everything that could be possibly need. They went straight in pretty much ten minutes per side to fit the grills and complete the project. Thank you. 


If you would like more photos of the inside fans etc just let me know, other wise we will catch you at the shows.

We had the final Cat sea trial yesterday. Engine room temps have dropped significantly which is an excellent result! 


On Sunday we had a wet trip home with a heap of spray, when we got in there was basically no water or spray to be found other than a little from one of the shaft seals, thanks for your assistance through the project, the results are outstanding and I'm sure in the long run the investment in the grills will reduce maintenance in the engine room.
