VBASE® Hydro T-EL™

Fully Formulated Hydropower Turbine EAL

VBASE® Hydro T-EL™ is formulated from premium fully saturated synthetic ester hybrid base oil and was designed as a high-performance hydropower turbine oil capable of meeting the EPA standards for Environmentally Acceptable Lubricants (EAL) according to the 2018 Vessel Incidental Discharge Act (VIDA).

In rig testing, the performance of fully formulated Hydro T-EL met and exceeded major OEM turbine requirements. In addition, Hydro T-EL outperformed the industry leading petroleum lubricant.



Hydro T-EL Oils are formulated with a proprietary high-performance base oil and an ashless, zinc-free additive package that provides exceptional thermo-oxidative stability, enhanced lubricity and load carrying, water and air separability, and protection against rust and corrosion.  

With high heat capacity and high viscosity indices, Hydro T-EL oils provide superior protection and lubrication across a broad range of operating temperatures, speeds, and applied loads. High heat capacity provides effective and efficient heat removal from rotating components enabling reduced tailrace water temperatures. High viscosity indices and lower traction coefficients provide improved efficiency in operation enabling reduced water draw. 

As an essentially non-compressible fluid, Hydro T-EL oils provide excellent load carrying capacity during both boundary lubrication and high speed, high pressure EHD lubrication regimes. This enhanced pressure behavior reduces the risk of wear and bearing contact under severe operating conditions.

Hydro T-EL™ Customer Benefits

Thermo-oxidative stability

Thermo-oxidative stability for long service life across a broad range of applied temperatures. Enhanced resistance to coking and varnishing.

Excellent Solvency

Excellent solvency means a cleaner product on changeover with reduced varnishing and deposits.

Rapid Air Release

Rapid air release gives reduced foaming and minimizes the risk of cavitation in high circulation applications and small reservoirs.

Rust and Corrosion

Rust and corrosion protection for both steel and yellow metals.

Broad compatibility

Broad compatibility with a wide range of base oils, additives, seals, and coatings means a reduced risk of fouling, leaks, or salting out of incompatible components.

High viscosity index

High viscosity index ensures consistent viscosity across a broad temperature range.

High Heat Capacity

High heat capacity enables the removal of heat from rotating components providing consistent temperature profiles within the lubricating film.

High load carrying capacity

High load carrying capacity ensures performance across all lubrication regimes with exemplary performance under high speed and pressure.

VBASE® Hydro T-EL™ Sales and Support

The VBASE® team has extensive analytical capability and expertise. When provided with samples of your current formulated oil, we will work with you to validate compatibility to ensure a smooth transition.

The performance of VBASE®  base oils surpasses that of both mineral base oils and traditional synthetic ester base oils. If your equipment requires a modification of the properties of the current Hydro T-EL™ formulation, a range of other VBASE® Base Oils are available.

Our Planet

Sustainability and Circular Economy
The desire for sustainable solutions for companies in every industry has never been greater, but sustainability is about more than just being safe for our environment. By developing VBASE® oils with improved efficiency and greater stability, oil lifetimes are extended and waste reduced. Sustainable oils also reduce fuel consumption and emissions by increasing overall equipment efficiency. At the end of oil life, VBASE® plans to work with our customers to bring used oil back for reconditioning, repurposing, or remanufacturing. Work to develop methods to maximize reused content in remanufactured oils is ongoing.

As VBASE® grows, it is our goal to develop a supply chain that minimizes environmental impacts of transportation and distribution while maximizing positive effects on local economies by manufacturing in region and sourcing local natural feedstocks.

Environmentally Acceptable Lubricants
VBASE® strives to produce oils that deliver the highest performance and greatest energy savings without compromising our environment. This new family of products enables the use of environmentally acceptable lubricants (EALs) in many environmentally sensitive areas such as hydropower plants, agricultural & forestry equipment, and marine environments.

VBASE® lubricants have high inclusion of renewable carbon (>50%), are biodegradable (>60% by OECD 301B), non-toxic (OECD 201, OECD 202, OECD 203, OECD 236), and do not bioaccumulate (OECD 117).
