R.I. Firm Nets Turbine Tech Funding
Rhode Island-based Aquanis Inc. has received a National Science Foundation (NSF) Phase I Small Business Innovation Research (SBIR) grant of $224,969 to accelerate the development of the company’s wind power technology.
Specifically, the grant will go toward further developing and testing a device that Aquanis says can improve the efficiency and extend the service life of utility-scale wind turbines.[adright zone=’190′]
The Aquanis system features a blade-mounted plasma flow actuator, which is a software-controlled, solid-state electrical device that the company says is simple and inexpensive. The system is based on patented technology developed at the University of Notre Dame.
The six-month NSF grant will fund the development of a new actuator design that is expected to at least double the efficiency of the device, according to Aquanis.
“We are excited about this Phase I SBIR grant, which will give us the opportunity to make the technology viable at ever-larger scales,” says Neal Fine, CEO of Aquanis. “The simplicity of our plasma actuator technology provides the basis for an inexpensive, no-moving-parts control system that will allow wind turbines to react instantly to changes in the wind.”
The company has also been awarded an Innovation Voucher grant from the Rhode Island Commerce Corp. The $50,000 funding will support the company’s research partners at Brown University’s School of Engineering. The grant will provide access to Brown researchers who have developed advanced computational fluid dynamics tools that will assist in Aquanis’ product design.
“Brown’s computational resources will help to cut years off of our product development cycle,” adds Fine.
Altech Unveils New Ground-Fault Protectors
Altech Corp. – a New Jersey-based supplier and distributor of electronic and control components, including for the wind industry – has rolled out a new line of UL ground-fault equipment protection (GFEP) devices.
According to the company, the technology enables the reliable protection and operation of equipment wherever and whenever ground faults may occur. In all three series, ground-fault sensitivity levels range from 10 mA to 500 mA.
The devices are designed to prevent costly production shutdowns due to AC and DC pulsating ground faults, as well as overloads and short circuits.
The UL 489 branch circuit breaker with ground-fault relay (GFL Series) combines a ground-fault equipment protector with a UL 489 branch circuit protector, which eliminates the need for upstream circuit protection.[adleft zone=’190′]
Next, the UL 1053 ground-fault sensing and relaying device (GF Series) provides residual current protection for circuits with loads up to 63 A. It represents an ideal retrofit GFEP where standard overload and short circuit protection is already being provided by other means, the company explains.
Lastly, the UL 1077 ground-fault relay with overload protection (GFR Series) serves as a combined equipment ground-fault relay and supplementary protector, the company says.

AMSOIL Offering Pre-Filtered Hydraulic Oils
Hydraulic equipment manufacturers have long recognized the benefits of clean hydraulic oil in preventing system wear, sticky valves and leakage. An estimated 75% of failures are related to foreign particles in hydraulic oil. Because clean, quality hydraulic fluids offer significantly longer system life and like-new system performance, AMSOIL announces that its hydraulic oils are manufactured pre-filtered, with no need for extra handling or filtration.
Multi-Viscosity Ashless Hydraulic Oil (MVH) and AMSOIL Synthetic Multi-Viscosity Hydraulic Oil (HV) are prefilled into new containers at ISO cleanliness level 16/14/11 or better, surpassing the original equipment manufacturer’s requirements.
AMSOIL HMV is designed to provide an extra measure of protection at a lower cost compared with other multi-viscosity hydraulic oils. It features a high viscosity index for superior performance in extreme temperatures. HMV offers excellent wear protection for pumps and motors, while its ashless formulation is safer for the environment. It is compatible with other hydraulic oils, providing a safe option for complete oil change or as a top-off oil.
The AMSOIL HV blend of high-viscosity-index base oils and performance additives provides all-season protection and reliable operation in all types of hydraulic systems. Its proven wear resistance and varnish control deliver maximum hydraulic system performance and life. HV is additionally tailored to promote energy efficiency and foam suppression.
Both the HMV and HV products exceed the requirements of important industry specifications, such as Parker Hannifin HF-0, HF-1 and HF-2; DIN 51524 Part 3; Vickers I-286-S; and M-2950-S, and are recommended in wind turbine hydraulic systems, such as Hydac. All AMSOIL hydraulic oils are suitable for use with high-efficiency 3 micron filter systems to keep the oil exceptionally clean in service. They also readily separate from water to prevent harmful deposits and oil breakdown, the company says.

Mobil Rolls Out New Synthetic Gear Oil
The Mobil SHC Gear 320 WT is ExxonMobil’s newest high-performance synthetic gearbox oil backed by a seven-year limited warranty for main wind turbine gearbox applications. As the industry’s first gearbox lubricant to be backed by a seven-year warranty, the Mobil SHC Gear 320 can help maximize equipment reliability and availability across a wide temperature range – a critical consideration for wind farms, which often operate in extreme climates and remote locations.
The next-generation gear oil is formulated to help deliver outstanding protection for critical turbine components over long oil-drain intervals. In extensive bench and rig testing, the Mobil SHC Gear 320 WT has shown the ability to deliver the specific, key performance benefits needed to support wind turbines operating in a wide range of onshore and offshore conditions, including the following: outstanding protection against micropitting and wear; reliable foam-control performance; exceptional water tolerance; and strong oxidative stability and excellent viscometrics, even at temperatures as low as -45°C (-49°F).
The Mobil SHC Gear 320 WT is certified for aquatic non-toxicity applications by the International Maritime Organization 493/02 test.
