PRAB's Guardian coolant recycling system is a fluid reclamation management tool for operations with industrial coolant or washwater reservoirs. The Guardian system reduces new fluid purchases by up to 75 percent and reduces waste fluids up to 90 percent by recycling used coolants, according to the company. Free-floating and mechanically dispersed tramp oils are reduced to 0.1 percent or less at process rates of 90 to 1,500 gph. Guardian systems operate on a continuous overflow process, providing multiple passes to prevent rancidity.
