Developed recently, after the expiration of the patent on I/R Ultracoolant, this product utilizes a Polyol pentaerythritol(PE) ester with a unique PAG and additive system designed to replicate the original products. The PE oils offer life comparable to the IR Ultracoolant and should be used for higher temperature operations or adverse conditions.
38459582 Ingersoll Rand Ultracoolant should not be mixed with other oils, particularly PAO and petroleum base products.
