Recycled Engine Coolant, Inc (REC) has been in business since 1994. REC has extensive experience in engine coolant recycling using distillation-based multiple technology systems. This process, developed and patent-pending, has adequately demonstrated to sufficiently reclaim pure base fluid, that when properly inhibited, has satisfied ASTM engine coolant standards, such as ASTM D6210 and TMC RP-329. REC also meets the ASTM D6471 standard, a recently published specification for recycled pre-diluted engine coolant.

This process includes two important phases: purification and reinhibition. The hardware processes the used engine coolant to remove old inhibitors and contaminates. This coolant is now clear in appearance and has reduced undesirable anionic contaminates in the permeate. Upon completion of this process, this coolant has demonstrated that the coolant processed at REC is similar to that of virgin ethylene glycol and deionized water. It follows therefore, that the use of quality and well documented inhibitors would result in a product that performs similar to virgin coolants.

Having completed the purification process, virgin ethylene glycol is added to set freeze point to -34 degrees F. This product is now to be blended for organic, inorganic, or a hybrid coolant that will be a fully formulated ethylene glycol based engine coolant that meets the standards for light duty and heavy duty vehicles and the standards of ASTM D6210 and TMC RP-329. This product is a prediluted antifreeze (50% volume minimum) based engine coolant. It is proper to mix engine coolants, ethylene glycol (no oil) into one waste collection tank per location.
