Rotork chosen for major Irish water upgrade

Rotork’s intelligent CKc range of modular electric actuators have been chosen as part of a major modernisation programme at a water treatment plant in Ireland.

Coffey Water awarded the contract to Rotork for its Killkit water treatment plant in County Monaghan.

According to a statement from Rotork, the CKc actuators were selected as they met the specifications of the application in a compliant and cost effective way. On top of supplying, installing and commissioning the actuators, Rotork also took responsibility for the design and fabrication of the adaptation components required to automate the previously hand operated penstocks.

The penstocks are now fitted with CKc double-sealed actuators which are certified IP68 watertight and temporarily submersible (8 metres for 96 hours). Increased penstock protection is provided by independent torque and position sensing, continuous valve position indication, even during power loss, and a safe, motor-independent handwheel. CKc actuators incorporate the Centronik integral starter and control module providing local control switches, monitor relay and a datalogger enabling data extraction for analysis, diagnostics and asset management, according to a Rotork statement.

The project is part of a contract for Irish Water to upgrade the Lough Egish Regional Water Supply which will see €4.5 million investment in the Killkit Water Treatment Plant with the aim of benefitting the approximately 12,000 consumers in Country Monaghan. When the upgrades are completed, the treatment plant will have an increased design output of 5.5 million litres per day.
