The Glyclean ARS-100 is designed to store and recycle up to 100 gallons of antifreeze in less than 30 minutes. It refines used ethylene glycol and water mixtures with an additive to neutralize acid and replace inhibitors to a like new condition. The unit incorporates two replaceable filters. The final filter is capable of removing suspended matter of 5 microns or larger. The unit has the ability to provide aeration for oxidation and removal of dissolved metals.
