Our Story
Thermal Mark was founded in 2002 by Managing Director Marc Gauci to lift the standard of support in the transport refrigeration market across the Sydney, and New South Wales region.
From its early days as a small workshop, the business has grown alongside its customers, expanding premises, capabilities and partnerships to deliver a better experience for fleet and owner-driver operators.
In 2025 Protran Solutions acquired Thermal Mark and the journey now begins….

“We partnered with Protran Solutions on creating 11 refrigeration fit out’s in Hyundai iLoads.
We are really happy with the way the fit outs were produced, it was important to have an instantly cold fridge in the back of our vans, to keep our awesome Kombucha called Amplify chilled at all times.
Protran Solutions provided excellent customer service, communication and one issue we did have, Protran Solutions came straight out to inspect and assisted with picking up the van taking it to the workshop and dropping it off, going above and beyond to assist Frucor. Thanks Protran Solutions, we are very happy with the service!”

“Having been involved in Commercial and Marine Refrigeration for years I was impressed with the full installation of a Protran Solutions Refrigerated Truck Body to one of our new vehicles-including the engine bay fitment.
The reasonably priced quality refrigeration box and install is exactly what we required.”
