What We Do

Recycled Liquids

IRSI is at the forefront of coolant development and has risen to be one of the industry leaders by developing and upgrading its processes utilizing patented advanced distillation techniques. IRSI utilizes a vacuum distillation process to recover and purify spent engine antifreeze / coolant to meet and often exceed ASTM performance standards (D-3306 and D-6210). The remanufacturing process primarily produces a solution that’s pre-mixed with 50% distilled water and 50% ethylene glycol. This pre-mixed solution is blended with corrosion inhibitors and additives to produce a variety of fully formulated products for the use in automotive (D-3306) and heavy–duty (D-6210) engines.

Being one of five distillation facilities in America using this newly patented process, which IRSI developed, our product quality and efficiency is unrivaled by any competitor. Our remanufacturing process also allows us to process used coolant / antifreeze streams from other recycling processes that leave a waste stream that only IRSI patented process can recover.
