TIF (Totally Internally Flanged) & IF (Internally Flanged) Tanks

Where space restrictions apply, the Dewey Waters TIF & IF sectional water tanks are the best storage option to allow you to maximise storage capacity. Standard access requirements request a clearance of 500mm around the tank for assembly and maintenance purposes. With the Dewey Waters TIF patented design & the IF design, these access requirements are reduced. These tanks are designed so that it is constructed from within, requiring less space for assembly. The tank may be positioned up against a wall or column, leaving space for other equipment within the plantroom.

Hand Layup TIF:

All side, base and lid panels are totally internally flanged.

Hot Press IF:

All side, base and lid panels are totally internally flanged, with the only external bolts and flanges around the perimeter edges.

The TIF is a more versatile & maintenance friendly solution than the Hot Press IF:

TIF & IF sectional water tanks should only be used when there is no space available to fit a tradtional sectional tank. These types of tank can be built close to walls and areas with restricted access. As there is no external access to the tanks after assembly, maintenance and rectification of any problems can be difficult or impossible.
