- LIFETIME – more than 20 years. Classic batteries with recombination plug have much longer life than VRLA batteries, in which it is not possible to refill water.
- SAFETY– reduced requirements of ventilation to the level required by the VRLA batteries, the minimum emission of harmful gases from the liquid electrolyte, fading the flame back, two-way adjustable pressure inside plug protects the system from mechanical damage as a result of uncontrolled growth or drop in pressure, the possibility of charging the battery at increased voltage with new design plug. Flame arrestor prevent external flames from penetrating the cell. Bi-directional recombination plugs are resistant to overload.
- ECONOMY– significantly reduced the frequency of water refilling (12-15 years topping-up interval), recombination plugs are optimized to work in full lifetime of the battery.
- FLEXIBLE – the ability to match amount of plugs to specific capacity of batteries.
Bi-directional recombination plug principle of operation
When using lead acid battery as a result of electrolysis of an aqueous electrolyte solution are separated hydrogen and oxygen. These gases in air may form explosive mixtures. Additionally the electrolysis reduces the amount of water in the electrolyte, which must be relatively frequently replenish in the battery. The conversion of hydrogen and oxygen in steam is an exothermic process. The heat emitted during the recombination process inside the sealed battery significantly accelerates the degradation of the lead electrodes immersed in an electrolyte. Therefore, the process is preferably carried away from the recombination with the electrodes, thus increasing the life of the entire battery. The innovative design of the gases generated during the electrolysis of water from the electrolyte when it reaches the plug in a controlled manner are converted into steam. Water vapor then condenses on the walls of plug. After cooling, as the water flows back into the battery. In order to achieve the most efficient gas recombination plug except the construction of a special catalyst system was also used bidirectional valves which automatically regulate the pressure inside the unit to achieve the best value. In order to maintain safe operation of the system pressure regulator over is mounted flame arrestor in the plug in addition to the single fuse hydrogen, in the form of a ceramic flame screen. In such designed plug gas emissions is minimal and safe for the surrounding environment. New recombination plug with two-way valve system, while maintaining the proper operation, maintenance reduces the frequency of replenishing the electrolyte level in the battery. New design of recombination plug increases the safety of the battery in areas with limited ventilation while maintaining the level of gas recombination at the highest possible level.
For appropriate operation of recombination plug the cell must be properly sealed . Special construction of pillars’ grommets and precise gluing of lids – confirmed with pressure test – causeshat recombination plugs are excellently working with SLA BATER cells (OPzS and SOPzS).
