1,000 Litre Insulated Water Tank

Our 1,000 Litre Insulated Water Tank is made from WRAS approve polymer with an insulation jacket engineered to prevent condensation and effectively reduce thermal and energy loss.  Insulated water tanks are designed for use where temperature regulation is key and for the prevention of overheating or freezing of liquids. 

Insulated water tanks are often used in conjunction with in-tank heaters or coolers to reduce running costs.  The Insulation is available as 13mm or 25mm thickness and the foam used is a more effective insulator than traditional tank jackets.

This insulated cold-water tank is a one-piece mould, seamless, rotationally moulded tank that guarantees strength, impacts resistance and durability. It is manufactured from MDPE medium density polyethene and UV stabilised for many years outside use.

Insulated Drinking Water Tank 

All drinking water tanks are manufactured from WRAS approved polymer (Water Regulations Advisory Scheme) and available in black, boat blue or natural. 

Regulation 31 Approved Tanks 

Our plastic water tanks manufactured from WRAS approved material are DWI approved and meet the specific requirements of Regulation 31. This ensures that water suppliers producing and distributing drinking water only use products that do not cause any detrimental effects on the safety or quality of the drinking water. 

Fluid Category 5 Insulated Tanks 

In many installations, potable drinking water tanks which are connected to the mains water supply will need to have a type of AB air gap to be fluid category 5 approved.  More details on tank installations that come under this are available here. 

Customisation of fittings & equipment mounting. 

These insulated water tanks are available with tank modifications to suit your project.  Liquid level sensor assemblies, fill pipes, PN16 and ANSI flanged connections, welded BSP outlet and sockets. Bolt down lid and side access hatch are available for access for cleaning, installation, and maintenance of water pumps.
