Industrial operations like factories, mines and utilities are constantly challenged to refine their processes to reduce costs. Investments in automation have delivered on making processes more efficient and repeatable, and the flow of data such automation can provide has also delivered the means to pursue even finer incremental improvements. The richness of that information is the key to gains in material yields, energy efficiency or asset reliability. The challenge is to apply a mix of engineering (and IT) skills and disciplines that can harness that data, and deliver it to a mix of stakeholders each with different ways of using it.
One such firm that has become a reliable engineering partner to Irish industry is Gilroy Control Systems. With a history spanning 40 years and operations in Cork, Dublin and Belfast, Gilroys has developed the expertise to help over 1,100 customers in industries as diverse as life sciences, building materials and food processing make use of their automation and sensory data drive process and business improvements. In the last few years, Gilroys has found customers increasingly looking beyond core processes and equipment, towards improving energy and water efficiencies.

Such sustainability-focused projects pose unique difficulties: assets like boilers, electrical switch panels and water-treatment plants have historically been relatively isolated. Putting utility consumption data into more context than ‘date-and-time’ means building a bridge between different types of systems. In addition, ‘reporting’ is not straightforward, as uses for the data range from re-engineering utility asset control algorithms to supporting carbon reporting to governments and customers.
Gilroys took on board all these complexities for a recent project with one of Ireland’s largest food processors. An operation that spans preparation, cooking and chilling, this firm’s success meant growth in size and related environmental footprint, so energy and water had come into focus as areas to save. A dedicated team was put in place, charged with establishing a measurement and reporting system that could grow with the business and be non-disruptive to current systems and work processes.
Connectivity was a bigger job than previously appreciated. Existing line control systems in production would be relatively easy to access, but different types of programmable automation controllers (PLCs) on different types of plant meant that data would be structured and described differently from point to point in the plant. Measurement of the electrical data would require sub-metering across a wide physical space, and networking costs looked to be prohibitive, as well as potentially disruptive, should a large cabling project be needed.

To solve the energy metering and connectivity problem, Gilroys introduced EpiSensor into the situation. EpiSensor is another Irish success story – based in Limerick, it is a leading firm in the development of smart sensor networks. By taking advantage of technology evolution in networking, cyber security and sensor technology, EpiSensor is able to avoid the cost and disruption associated with traditional metering approaches and that meant a faster, more economical project. EpiSensor’s smart energy meters provided the detailed usage information needed to ensure that variations in consumption could be captured in relation to the production and overhead areas of the operation.
