Renewable Lubricants

Hydro Safe is a brand specializing in patented, biodegradable hydraulic fluids made from renewable, vegetable-based resources. A division of Renewable Lubricants, Inc., it has supplied hydraulic oils for equipment since 1996 and provides technology to major elevator companies, including OTIS, Thyssenkrupp, KONE, and Schindler. Its Hydro Safe Select fluids are available in ISO VG-32, VG-46, and VG-68 grades and are formulated for fleet, marine, industrial, and outdoor hydraulic systems.

Made using oils such as canola and soy, the products are designed to combine biodegradability and low toxicity with lubricity and oxidative stability. Their zinc-free additive system supports high-pressure pumps, while anti-wear performance is tested against Vickers vane-pump standards. The fluids are also formulated to resist moisture and rust in fresh and seawater. Hydro Safe presents its products as an alternative to conventional petroleum-based hydraulic oil, with benefits including reduced wear and improved energy efficiency. The biodegradable, non-toxic oils may also qualify projects for LEED points in the Materials and Resources category.
