Softstart UK wins million pound order from Egypt

Posted: Monday 9th November 2009

Softstart UK, UK leader in the soft starter sector, has just received, from the Egyptian government, its largest ever single order for 6 of its new MV DS medium voltage soft starters.

Softstart is one of the very few companies that can supply the 11kV 2.1MW units needed for running up the 18 pole motors driving the waste treatment booster pumps at the El Amiriiah pumping station. IP54 enclosures are specified owing to the presence of hydrogen sulphide gas which attacks copper, necessitating that all bus-bars are tin plated and all circuit boards lacquered.

The contract includes automatic power-factor correction equipment to ensure near unity power-factor while the motors are running on the 11kV mains supply. Softstart UK will commission the units on site, simplified by the touch screen digital control and monitoring, door mounted PC and the units will be connected via Ethernet to the pumping station supervisory SCADA system. Electronic soft starters offer a superior solution to autotransformer starting and a more cost effective solution than full VSD control and smooth controlled soft starting and stopping are critical to avoid violent pressure surges that otherwise might rupture the pipeline system.
