Recirculation device for the freshest water

GFU-325LV

The Flow-Thru Steel Tank, 325 liter / 85.86 gallon vertical model, is designed for large-capacity water systems that require continuous water circulation to prevent stagnation. Featuring GWS’s patented Flow-Thru™ technology, this tank ensures that water remains fresh by diverting and flushing water in and out during system operation.

The robust steel construction, combined with a 1.25" NPT connection (+ BSP adaptor) and a gray finish, makes this tank suitable for demanding applications. With a pre-charge pressure of 1.4 bar / 20 psi, it provides reliable performance in constant pressure systems, ensuring water quality and system efficiency.
