Tailored to your specifications
At DTS, we recognise that every project is unique. From initial consultation to final installation, we collaborate closely with you to deliver reliable, custom‑designed stainless‑steel solutions.
Our Normanby facility in Taranaki fabricates using premium 304, 316 and 2205 Duplex materials, ensuring exceptional quality, hygiene and durability.
Bespoke pillow plate design
We specialise in laser‑welded dimple plate / pillow plate cooling pads, engineered precisely to your requirements.
Our in‑house flat‑bed laser welder, unique in New Zealand, allows for customised pad layouts that significantly improve cooling efficiency while reducing operating costs.
Our people are our strength
Between then, our highly qualified team have 180+ years of experience in making food-grade tanks and 350+ years of engineering experience.
Lean manufacturing excellence
Committed to lean manufacturing principles, we streamline production to minimise waste and maximise resource utilisation.
This ensures every tank is built with cost‑efficiency, quality and sustainability in mind, not just during manufacture, but throughout its operational lifespan.
