Edited by the Engineeringtalk editorial team Dec 19, 2000

Roomfoss has won an order to supply seven Cutler-Hammer F660 Motor Control Centres (MCCs) to West of Scotland Water's Daldowie treatment centre

Roomfoss Limited, a market leader in the design and manufacture of control panels, has won an order to supply seven Cutler-Hammer F660 Motor Control Centres (MCCs) to West of Scotland Water's Daldowie treatment centre.

Roomfoss is a key Cutler-Hammer System Builder and will supply 150 Cutler-Hammer F660 columns for installation in the Daldowie centre's sludge dryers to provide critical monitoring and control of the thermal dryers that granulise waste sludge into fuel granules.

This will assist the thermal drying process of 65,000 tonnes of dry solids equivalent per year to be used as a waste dried fuel alternative to coal at a Scottish power station.

This project forms part of West of Scotland Water's overall strategy to invest in new technologies and advanced methods of beneficially recycling sewage sludge, in line with the EU directive prohibiting the disposal of sewage sludge at sea.

As part of this investment, Cutler-Hammer equipment will be installed at four major new sludge treatment centres which will on completion, serve 98 per cent of West of Scotland Water's customers.

"The work at the Daldowie Sludge Treatment Centre forms part of a complete re-development by West of Scotland Water under the PFI initiative to improve its waste treatment and disposal," said Ron Leadley, Managing Director of Roomfoss Limited.

"To meet EU Directives, they needed systems that could perform to the highest standards.

Cutler-Hammer Motor Control Centres are ideally suited to the critical monitoring and control requirements of thermal sludge drying processes and Roomfoss delivered the systems to provide West of Scotland Water with the level of performance and reliability that they require." The order for the Cutler-Hammer MCCS was placed by Andritz, expert for mechanical waste water and sludge treatment, on behalf of SMW Limited - a wholly owned subsidiary of Scottish Power.

West of Scotland Water appointed SMW to manage the project as part of its PFI environmental initiative.

The F660 MCCs are to be installed in two switchrooms.

Each MCC is 15 metres long and incorporates the Cutler-Hammer motor control products, providing a type tested assembly with fuse switches and type two co-ordination.

Cutler-Hammer's F660 Motor Control Centre is a totally type tested assembly complying with BS EN60 439-1 in conformance with the Low Voltage Directive.

The product is rated from 600 to 4,000 Amps and 25kA for one second, 50kA for one and three seconds, and 80kA for one second.

Sections are available in either fixed or withdrawable construction and standard ingress projection is IP 54 with separation available up to Form Four type seven.
