Single Point Battery Watering System | Millennium SPW™

Supplier: Multi-Shifter Australia

The Millennium SPW™ Single Point Battery Watering System is an accessory that makes the difficult task of watering industrial batteries elementary, the entire process takes just 30 seconds or less per battery.

Price Guide: POA

It consists of automatic shut-off valves interconnected with tubing that replace the existing vent caps. A quick coupling allows the end of the tubing to be connected to a water supply. Once connected, water flows into each cell until it reaches the appropriate level. A flow indicator tells the operator when filling has been completed. The entire process takes just 30 seconds or less per battery.

Millennium SPW™ is the most innovative, advanced, versatile, and user friendly system yet. At a glance, many of the superior features are evident. Everything from the clampless polypropylene tubing, flame arrestors, flip top cap, and the low profile to the solid protective shroud. But what’s even more impressive is the structure inside the valve.

The Millennium SPW™ valve is capable of working independent of water pressure*, allowing you to use a variety of water supply options. In addition, the Millennium SPW™ valve includes a built in water barrier to block the propagation of a flame front from entering adjacent cells in the event of accidental cell gas ignition. The recently improved flame arrested cap now includes a patent pending internal flame arrestor for use in applications such as water less batteries where the water trap may dry out.

How it works

The Millennium SPW™ valve operation features a breakthrough patented technology that sets a new standard for reliability and versatility with single point watering. Without levers, hinges, or pivot action, Millennium SPW™ valves can operate independently of refill water supply pressure* to accurately control cell electrolyte levels.

Through Fluidic Displacer Valve Technology, it uses a dual, balanced valve design that allows the displacement force to act directly through the center of the valve without any mechanical leverage. The Millennium valve is very sensitive to the displacement force, allowing a very small displacer to be used.

At the same time, it is very insensitive to variations in the water supply pressure used, making it a true multi-pressure valve. Fluidic Displacer Technology allows the Millennium SPW™ valve to maintain the low profile and easy tube routing features found in Flow-Rite’s previous PowerStream™ and Snap-Fill™ systems.

*The Millennium SPW Valve requires 3-35 PSI static (no flow) pressure and a minimum of 2GPM flow rate (measured through the purger) for proper operation.

Cost Savings

A properly watered battery lasts longer and performs better.After installing your Millennium system, you will realise cost benefits including extended battery life, increased performance, and cleaner floors, equipment and battery tops.


Fill batteries without having to remove the vent covers. Avoid battery acid burns, ruined clothing, and noxious fumes. Add optional flame arrestors to prevent ignition of flammable battery cell gasses.

Time saving convenience

Snap on/snap off water connections and fast filling turn the often ignored task of watering batteries into a quick, simple task allowing you to fill each battery in 30 seconds or less!
