Automated stainless steel tank manufacturing for OEM Customers
ACT operates a dedicated production line focused entirely on stainless steel tanks. Automation allows us to keep dimensions consistent, control weld quality and scale production when volumes increase.
The line was developed specifically for manufacturing water tanks used in heating, hot water and HVAC systems.
Dedicated OEM tank manufacturing
We manufacture stainless steel buffer tanks, indirect water heaters and chilled water tanks on a dedicated, fully automated production line. This ensures repeatable geometry, controlled weld quality and stable output — regardless of production volume.
Built for durability and system performance
By processing stainless steel only, we eliminate contamination risk and ensure long service life. Our tanks are designed for demanding applications such as heat pump systems, data center cooling, and domestic water storage — where durability and reliability are critical.
Industrial-scale OEM tank manufacturing with flexible output
With a total annual production capacity equivalent to 30 million liters of tank volume, we have the industrial-scale capabilities to support OEM growth and reliably meet large-volume global demand.
1–100,000+
Units
We remove barriers to entry. Whether you need a specialized prototype or a massive industrial rollout, our lines adapt to your needs with no minimum order constraints.
100% EU-Certified
