Initial discussions between the two companies started in 1993, which saw the start of an extensive period of development cooperation resulting in the first production converter order in 2004.

These first 1000 units have a combined energy output of 2500 MW à‚— the equivalent of two conventional power stations. Many of the converters are now in service in Europe and North America. In the UK, the converters are in use at a new offshore wind farm at Burbo Bank near Birkenhead.

Produced at Converteam’s Kidsgrove plant in the UK, the converters form the heart of the internal workings of the wind turbine system.

The giant rotor blades, driven by wind, turn the generator, which produces electric power. The converter then takes that supply and transfers it to the national grid at a constant frequency and voltage that consumers can use.

The occasion was marked with a plaque unveiling followed by a reception at Crewe Hall. Among the assembled guests were long-serving members of the Converteam staff that had worked on the project since its inception, along with local councilors and Advantage West Midlands representatives.

Councillor Robin Studd, portfolio holder for regeneration and planning at Newcastle Borough Council said, “The Council is proud to be associated with Converteam and wished to congratulate them and their workforce on achieving this significant milestone.

The company is a leading edge manufacturer, important to both the [local] economy and because of the contribution they are making to address climate change through their wind turbine technology”.

Converteam can draw on more than 100 years history of electrical engineering in electric motors, generators, power converters, control and automation systems.

This radio functions as an access point, repeater, or client and its water resistant enclosure permits it to be directly installed in areas that are exposed to harsh industrial or environmental conditions, including wash down areas, offshore oil rigs, and outdoor towers.

The RLX-IHW-66 offers Power over Ethernet (PoE), which allows the radio to be installed next to the antenna, reducing antenna cable loss and maximizing range. The 802.11abg radio is designed for global applications and uses an advanced combination of features to create a reliable, versatile solution for even the most demanding industrial networks.

The RLX-IHW-66 is equipped with RF-based Internet Group Management Protocol (IGMP) Snooping, a tool which allows multicast filtering at the wireless level, so that the radio transmitting data from the producer (such as a distributed I/O block) is able to identify the consumer (i.e. a PLC) and transmit the producer data directly to the consumer as opposed to multicasting the information to the entire wireless network. Since the RLX-IHW-66 sends the data directly to each of the consumers, it is able to confirm receipt of the data and retransmit the data if necessary. RF-based IGMP prevents crowding over the air by only sending messages where they need to go and it increases reliability by confirming receipt of the data.

The IP66 rating for enclosures guarantees that the product will be protected against high-pressure water jets from all directions, with a limited tolerance for ingress, as well as total protection against dust. This rating equates to a water resistance, dust-tight form factor. The RLX-IHW-66 can be used in industrial operating temperatures, and is vibration and shock resistant.

Mono Nov has the magic touch at Alcan

With the installation of five Mono NOV’s Merlin pumps at Alcan’s Power station in Lynemouth, Northumberland, UK, Mono has provided a successful and safe solution to a previous problems associated with submersible pumps.

The plant supplies coal fired power to the nearby Alcan smelting plant and has several nuisance water sumps across the site from which water containing coal dust is pumped into the main drains, which then flows via gravity to the treatment plant.

The presence of the coal particles in the water had caused frequent blockages of the submersible pumps and in addition abrasive wear was increasing the maintenance and downtime to every two months. The Mono pumps have now been in operation for 18 months without any problems.

The location of the submersible pumps at the bottom of the sump, in amongst the nuisance water, means they were often dirty and difficult for the maintenance staff to reach on their frequent and costly break down visits.

The pumps needed to be lifted out of the sump requiring the use of the associated lifting gear, which had to meet stringent health and safety compliance. The maintenance personnel also had to enter the sumps to relocate the pumps once they were repaired.

Thus, Alcan urgently required more efficient and reliable equipment and wanted to move away from submersible pumps, therefore surface-mounted progressing cavity pumps were selected with a proven track record of reliable service in the coal industry.

The Merlin industrial pump from Mono has a simple, rugged construction that is extremely reliable and easy to maintain with a wide variety of materials available to suit difficult applications.

A progressing cavity pump utilizes a hard rotor turning within a soft resilient rubber stator and the interference fit gives better seal and wear characteristics, eàŽ©nsuring that abrasive particles are easily handled with low wear rates.
