Sectional Water Tanks
A sectional storage tank can be used for storing large volumes of cold water for potable or non-potable use. Sectional water tank panels are moulded from the composite material Glass Reinforced Plastic (GRP), which provides a strong, solid and reliable structure. Suited for both internal and external applications, they are capable of withstanding harsh climatic conditions. Our tanks are delivered to site palletised and are assembled by our site crews. Whether it’s a water tank replacement or a new build, we have the experience, flexibility and knowledge to meet your requirements.
Sectional Water Tanks Range
Hot Press Sectional Tank – Insulation Thickness
38mm as standard (0.57w/m2/⁰C) & 50mm (0.40w/m2/⁰C) is also available
Totally Internally Flanged Sectional Tank – Insulation Thickness
25mm as standard (0.85w/m2/⁰C), 50mm (0.40w/m2/⁰C) is also available
Nominal vs Actual Capacity
Nominal Capacity is the volume of the tank when it is filled to the brim.
Actual Capacity is the volume contained within the tank up to the maximum working level. This is dependent on the inlet size and air gap selection.
