1. Design

The Aquamatic/BFS battery water refilling systems are used for automatically adjus-

ting the nominal electrolyte level. Venting holes are provided for letting off the gases

which arise during charging. In addition to the optical level indicator, the plug systems

also have a diagnostics hole for measuring the temperature and the electrolyte den-

sity. All battery cells of the design series EPzS; EPzB can be equipped with the Aqua-

matic/BFS filling systems. The water can be refilled by means of a central sealing

coupler through the hose connections in the individual Aquamatic/BFS plugs.

2. Application

The Aquamatic/BFS battery water refilling system is used in traction batteries for

forklift trucks. The water refilling system is provided with a central water connection

for the water supply. Soft PVC hose is used for this connection and for the hose con-

nections for the individual plugs. The hose ends are put onto the hose connection

sleeves located on the T or < pieces.

3. Function

The quantity of water required in the refilling process is controlled by the valve located

in the plug in combination with the float and the float rods. In the Aquamatic System

the existing water pressure at the valve turns off the water supply and ensures that

the valve closes securely. When the maximum filling level is reached in the BFS sys-

tem, the float and the float rods through a lever system close the valve with five times

the buoyant force and consequently interrupt the water supply reliably.
