Inside each Water Injector is a precision level-sensing valve enclosed in a strong protective housing. When the electrolyte level rises to reach the tip of the Injector, the valve shuts off instantly. There are no exposed parts to stick or break and individual Injectors are strong enough to survive the abuse of tough applications for many years of use.
There are no floats of any kind involved because this is not a hydrostatic system. It is a hydrodynamic system powered by the incoming pressurized water. One great benefit of this approach is that the actuating (shutoff) force of an Injector is typically 20 times stronger than the buoyancy available with a float. This makes Injectors virtually immune to “sticking” due to gummy residues in the cells. It is what gives them their legendary reliability.
The other enormous benefit of pressurized water is that it produces fast filling – which translates into productivity gains and cost savings. Furthermore, a short, 15 second fill cycle also raises operator confidence because he or she can be present and attentive during the entire filling operation. That is not possible with systems that take minutes to fill.
To achieve their superior speed and reliability, Water Injectors must be supplied with adequate water pressure. However, this is not a difficult requirement to meet. (See the link below on water supplies). For installations with only one or two batteries, we recommend our Watering Gun, our Stealth Watering System™, or a contract Watering Service.
Water Injectors are installed into each cell on a battery. Rugged tubing that runs through each each Water Injector forms a single continuous flow path on top of the battery. The water tubing itself has a large bore to minimize pressure drop. The system connects to any of our engineered water supplies with simple quick-connect couplings. A spinning flow indicator, on the water supply, stops when the battery is full. After filling, excess water in the tubing drains into the cells to prevent freezing in cold store applications. A typical 18-cell battery is filled in 15 seconds.
