MP Range 

The MP range of one piece tanks was created to keep carriage costs to a minimum. Dimensions have been carefully planned so that no tank takes up more than two pallet-spaces. This also means they have a smaller footprint which is ideal for areas of restricted space.

Two-Part Tanks 

These are an ideal solution where access is restricted to a standard doorway and are easily and quickly assembled by site operatives. The single horizontal joint seal is compressed by bolting through the predrilled flanges and connections are made via the preformed recesses in the encapsulated insulation. As with all our hand layup tanks, these are carefully manufactured using WRAS approved materials and are completely suitable for use with potable water. Standard two-part tanks are available from 910 litres to 5690 litres nominal and non-standard sizes can be made to order.
