Digital two-wire control is provided by Rotork’s proprietary Pakscan P3 system, the third generation of a market-leading product, capable of monitoring and controlling up to 240 field units without repeaters on a single highway with a length of up to 20 kilometres. Designed specifically for the valve actuation environment, Pakscan combines high reliability and efficiency with low maintenance costs. In providing the vital link between the actuators in the field and the centralised supervisory control room, Pakscan incorporates secure field communications with inbuilt network redundancy to maintain control even in the event of equipment or cable failure.

Rotork Pakscan has been widely adopted in many worldwide industries, where the use of a fully redundant two-wire bus loop linking multiple numbers of actuators over long distances is recognised as delivering reliable monitoring and control with dramatically reduced installation and cabling costs in comparison with traditional hard wiring.

The Olivenza Thermosolar power plant is the second plant to be operated by the Spanish company Ibereolica. Rotork supplied IQ range electric actuators with Pakscan digital control at the company’s first plant, Moron Thermosolar, and the satisfactory experience on this project, where installation and commissioning was performed on time and without incident, has enabled Ibereolica to select the same Rotork equipment again. As with the Moron project, Seridom has been the main contractor for Olivensa Thermosolar.
