Aztec Releases
Tensioner Pump

Texas-based Aztec Bolting Services Inc. has announced its latest tool: a new-generation electric tensioner pump designed for bolting applications, specifically in the wind and power generation industries.

“The tool has a unique footprint; it is 65 percent smaller than anything on the market,” says Larry Garza, owner of Aztec Bolting Services Inc. “Portability and compact design are key in our industry, and this tool has them both.”

The company says other design features include fast pressure-up and retract, a calibrated digital gauge, a multi-functional intrinsically safe remote control, and certified one point lift.

SKF Introduces
Excluder Seal

SKF – a supplier of bearings, seals, mechatronics, and lubrication systems and services – has announced a new axial excluder seal. According to the company, the HRC1 seal offers an ideal alternative to conventional rubber seals for protecting wind turbine main shaft bearings from contaminants.

SKF says the seal can help wind farm operators significantly reduce the risks of contaminant-related bearing failures and the high costs of associated unplanned downtime, repair and lost productivity. It is manufactured from a proprietary SKF polyurethane material exhibiting resistance to wear, abrasion, UV radiation and ozone.

In early field trials, SKF says it installed the HRC1 on 40 separate 2.5 MW turbines operated continuously under real-world conditions, and after three months, an initial inspection revealed only normally expected run-in wear.

HRC1 axial displacement seals are available in standard solid and split versions for shaft sizes from 1 meter to 3 meters. Custom solutions can be developed.

Moventas Offers
Lubrication Upgrade

Moventas says it has developed a gearbox lubrication upgrade for customers operating WinWind-made WWD3 turbines in order to help extend the machines’ lifetime considerably.

The first one of these lubrication upgrades will be carried out this summer in Kemi, Finland, where Moventas will upgrade 10 turbines for Innopower in the Ajos wind park as part of a larger service project.

Moventas will upgrade the entire gearbox lubrication system, install extra pumps for the main bearings, change the coolers and update the lubrication management logic. The installations take a maximum of five days per turbine, depending on the delivery scope.

“We have high expectations for this upgrade. Key main components should last until the end of turbine lifetime,” comments Raine Laaksonen, production manager for Innopower.

Northern Power
Teams Up In Brazil

Vermont-based Northern Power Systems Corp. has announced it is working to develop a new 3.3 MW wind turbine with Brazilian partner WEG.

Northern Power says the new turbine will be designed specifically for the Brazilian market. The development effort is part of an agreement between WEG and Tractebel Energia, a company of GDF Suez Group, under the Brazilian National Electrical Energy Agency research and development program.

WEG plans to produce the new 3.3 MW turbine in the southern Brazilian state of Santa Catarina and is expecting to leverage it first in the growing South American wind market and later expand with Northern Power for global deployment.

According to Northern Power, this new development effort will further complement the companies’ existing portfolio of utility-scale wind turbines, which is currently led by a 2 MW onshore turbine offering.

“Northern Power has proven to be a strong technology partner for WEG as we expand our business in the growing wind energy generation market in Brazil,” says WEG’s Joao Paulo Gualberto da Silva. “We are expecting this technology to be an asset for our global expansion in the wind space and look forward to partnering with Northern Power on global opportunities.”
