High power cabinet drive available in one week

High power drive users can now receive ready-made drive cabinet systems in as little as one week for emergency breakdowns, following the release of Control Techniques’ DFS series of freestanding drives.

INTRODUCING THE NEW COMMANDER SERIES

Control Techniques, part of the Nidec group of companies, has announced the return of its Commander family of drives.

HOSPITAL ELEVATORS REACH A NEW PEAK WITH DRIVES FROM CONTROL TECHNIQUES

Control Techniques’ E300 elevator drives have been selected for a major hospital modernisation programme in Mexico that will eventually see hundreds of new lifts installed across the country. Carlos Silva SA – a Barcelona-based elevator control specialist – won the tender to supply 50% of the elevator control systems required in the first phase of the modernisation programme. After many years of successfully using previous-generation inverters from Control Techniques, they chose the latest E300 drives for this new project.

Limestone Mine Benefits from Leroy-Somer Regenerative VSD Technology

A major metal and non-metal mining specialist based in the USA has adopted the latest Powerdrive FX variable speed drive (VSD) with dynamic braking from Leroy-Somer. The product is being used as a regenerative drive on a downhill conveyor at one of the company’s limestone mining facilities. Leroy-Somer was selected as the preferred supplier following a recommendation when the conveyor’s existing drive became obsolete.

Unidrive M700 VSD helps a large power station maximize cooling tower performance and reduce maintenance costs

The Power Station is now using Control Techniques Unidrive M700 variable speed drives from Emerson to control 22 cooling tower fans across two towers. Replacing a system that was first installed in 1975, the advanced new drive brought many benefits. It means that the fan speeds can be varied to minimize power usage at low unit loads, eliminate wind milling due to a lack of a braking system, minimize freezing potential in winter, mitigate fan vibration without removing from service, and eliminate seasonal blade pitch adjustments required to prevent motor overloads in the winter and low air delivery in the summer. Just the blade pitch adjustment itself resulted in a significant saving in man hours, which the power station estimates to be worth $38,000 per year.
