The Ingersoll Rand 15483522 92692284 Ultra Coolant is a polyglycol-based compressor lubricant intended for compatible rotary screw air compressors. Despite the product name, it is not simply a conventional water-based coolant. It serves as a working fluid in contact-cooled screw compressors, where lubrication, heat transfer and control of oil carryover all affect operating performance.
Inside an oil-injected compressor, the lubricant circulates through the compression process, helping seal the clearances between the screw rotors, reduce friction and absorb heat generated during compression. The fluid then passes through the separation and cooling circuits before returning to the compressor. Its formulation influences thermal behavior, deposit formation, lubricant consumption and the condition of downstream compressed-air equipment.
The 92692284 reference corresponds to the 5-liter packaging of Ingersoll Rand Ultra Coolant. The supplied 15483522 reference is retained as part of the product identification. When replenishing or replacing the lubricant, maintenance personnel should confirm the required fluid specification and ensure that the existing lubricant is compatible with Ultra Coolant.

In an oil-injected rotary screw compressor, the rotors draw in air and compress it while lubricant is injected into the compression chamber. The lubricant helps seal the rotor clearances, lubricate moving interfaces and absorb heat produced during compression. The resulting air-lubricant mixture then enters the separation system, where most of the entrained lubricant is removed from the compressed air.
After separation, the lubricant circulates through the compressor’s cooling and filtration arrangement before returning to the airend. Its ability to transfer heat, resist foaming and maintain suitable lubrication characteristics affects the overall operation of this circuit. Excessive foam, lubricant degradation or deposit formation can interfere with normal fluid circulation and separation performance.
Ultra Coolant is formulated for this operating environment. Its published performance characteristics include non-foaming behavior, varnish-free operation and high thermal conductivity. Actual service life depends on the compressor model, operating temperature, duty cycle, contamination levels and required maintenance practices. The stated maximum service interval should not replace condition monitoring or the prescribed maintenance schedule.
Ultra Coolant circulates through the compressor’s lubrication and cooling circuit. It interacts with the airend, separator, lubricant filter and cooling components as part of the machine’s normal operating cycle.

No. Ingersoll Rand identifies Ultra Coolant as a polyglycol-based lubricant for rotary screw compressors. It circulates through the compressor’s lubrication and cooling system rather than functioning as an ordinary water-based coolant.
Do not assume that it can be mixed with conventional mineral oils or other synthetic lubricants. Different fluid formulations may have different compatibility characteristics. Confirm the specified lubricant and follow the appropriate changeover procedure before changing fluid types.
No. The published figure is an upper service-life claim under suitable conditions, not a universal replacement interval. Operating temperature, compressor duty, contamination, maintenance history and the equipment’s requirements can affect the actual service interval.
Check the lubricant level, the operation of the oil cooler and temperature-control components, and the condition of the relevant filters and fluid passages. Also confirm that the correct lubricant was used and that the compressor is operating within its intended conditions.
