Guardian Coolant System Extends the Life of Coolants, Fluids


The Guardian Coolant Recycling System is a proven fluid reclamation management tool for operations with industrial coolant or wash water reservoirs. The Guardian system reduces new fluid purchases by up to 75% and reduces waste fluids by up to 90% by recycling used coolants.


Free-floating and mechanically dispersed tramp oils are reduced to 0.1% 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. Each turnkey system is designed for easy installation, quick start-up, and simple, efficient operation—clearly making it the best coolant recycling solution on the market today.
