A cylindrical tank in 500 L and 1,000 L, with fittings that screw into a captured stainless steel thread
[10/11/26] Southland Filtration has moved the storage tank in its PureLoop pure water storage and distribution system to a cylindrical design, for both PureLoop capacities, 500 L and 1,000 L. Its fittings screw into a stainless steel thread captured in the tank during rotomoulding.
PureLoop is a skid-mounted system that stores and recirculates purified water, with UV disinfection, an endotoxin filter and instrumentation for Type 1, Type 2 or Type 3 water. It is Australian engineered and manufactured, and the tank is the system’s storage component.

The PureLoop video turns the system through its front, side and rear views.
The cylindrical tank keeps the tapered, self-draining base that prevents water from standing in the tank.
On the square tank, the connection was plastic on plastic. On the new tank, a stainless steel insert is captured in the tank during the rotomoulding process, so fittings, whatever their material, screw into a stainless steel thread.
“The cylindrical design makes for a stronger tank, more robust, with a better appearance. We’ve captured a stainless steel insert in the rotomoulding, so when we screw our fittings in, whatever the fitting is, it’s not plastic on plastic. That means better sealing and an overall better quality product.” James Cox, Head of Production, Southland Filtration
