Automating GEL Circulation Technology for Continuous Processing

Gel Circulation Technology is the latest and most efficient process to change flooded lead ─acid batteries to VRLA products. It makes both acid drainage and time-consuming vacuum filling obsolete and results in a better product quality. The first installation of such a system was six years ago and is now used by some major battery manufacturers. The latest development of this well proven technology has been the move from batch process to a continuous operation. The main advantages are: (i) no time limitation to connect cells to the system, (ii) no preparation of the Gel mix before starting the circulation process, (iii) continuous and time-independent connection and circulation of cells. This presentation describes this improved process compared to the standard ‘two shot’ and batch circulation in terms of efficiency and costs.
