Glycol vs. Water-Based Hydraulic Fluids


Explore the benefits of each hydraulic fluid to discover which is best for your operation.

Explore the benefits of each hydraulic fluid to discover which is best or your operation.

With hundred of different hydraulic fluids available, it is often difficult to decioher which is best for your operation. Discover the hazardous properties, ISO 9001:2015 compliance, fire-resistance, and more of the glycol and water-based hydraulic fluids below.

Hazardous vs. Non-Hazardous

Glycol-based hydraulic fluids are commonly found in industries such as die-cast manufacturing operations that operate at high temperatures, due to their low cost and good lubricating properties. Even in a low-heat environment where the flashpoint may not come into play, leaks from machines cause a concern. Most hydraulic fluids are hazardous to the environment and, if introduced into the groundwater, can expose a business to substantial contamination fines.

If your glycol-based hydraulic fluid is not disposed of properly — accidentally or intentionally — you will face large fines from the EPA and local governments. Violations to the Clean Water Act can be levied up to $25,000 per day until the spill is cleaned up. In addition, you will be required to pay for cleanup costs and be exposed to an increase in insurance premiums.

Non-hazardous water-based hydraulic fluids can eliminate all of these risks for your company, while complying with the risk-based thinking for ISO 9001:2015. Implementing a water-based hydraulic fluid meets the requirement of mitigating points of risk for your business. Composed of naturally occurring components, water-based is non-hazardous in nature, eliminating the need for costly cleanup if introduced into the groundwater.

Fire Resistance

When your business is consistently operating at high temperatures, with potential for fires, it is important that your hydraulic fluid can keep up without the risk of fire ignition. Glycol-based fluids have a fairly low operating range of -30° to 150°C. Under high heat and pressure, where a failure in a line can produce a spray, a glycol-based fluid can present serious hazards.

Our non-hazardous water-based solutions are better suited for industries that run at high temperatures with risks for fire, due to their exceptional flashpoint that runs >350⁰ C. This is much higher than most glycol fluids. Keeping employees safe and producing a quality product should not be a trade-off.

The Right Non-Hazardous, Water-Based Fluid for Your Operation: Non-Haz FRHF 46

If you’ve decided that a water-based hydraulic fluid is the best solution for your business, then you are ready to find the right fluid. Look no further than Non-Haz FRHF 46. Unlike other water-based lubricants, Non-Haz FRHF 46 is a globally accepted, groundbreaking formula that enhances the overall performance and contains enough water to suppress fire ignition!

Our revolutionary formula is EPA approved — non-hazardous, non-toxic, and diethylene glycol free. More than non-hazardous and fire resistant, Non-Haz FRHF 46 increases lubricity with wear, extending the pump life; has exceptional heat-transfer properties that allow it to operate under high temperatures without breaking down; and works in alignment with the hydraulic system to prevent corrosion and deterioration of the machine.

Best of all, Non-Haz FRHF 46 was meticulously created to work without having to flush or clean your system that is currently using a glycol version. Simply add it to your existing water-based hydraulic fluid to start reaping the benefits of this groundbreaking formula.
