Shell Irus C-NA is a water solution of diethylene glycol and an effective additive package. In addition to water (approximately 40%) and glycol, it contains a combination of anti-wear agents and rust inhibitors designed to make it suitable for use in a wide variety of hydraulic systems. Shell Irus C-NA protects high pressure pumps from excessive wear. This product also offers good rust protection both in the fluid immersed sections of the system and in the vapor spaces where condensed water typically collects. Shell Irus C-NA is foam resistant and shear stable. Its higher specific gravity allows oil contamination to float on the surface where it can be removed by conventional skimming equipment. Low temperatures are not a problem since the product's glycol content protects against freezing.
