Farmed in Gippsland for three generations, G&K O'Connor produces some of Australia’s best grass-fed beef.

Last year, Rendertech partnered with Hennessy to upgrade the industrial control and SCADA system, and to commission new machinery at G&K O’Connor’s rendering plant.

Pioneering a world-first in automation, we implemented FACTORYTalk OPTIX as a SCADA platform in Rockwell - one of the first companies in the world to do so.

Our team was thrilled to help improve efficiency and operations for G&K O’Connor, while using our knowledge and skills to help shape the development of Rockwell’s platforms.

Crimp lugs, bi-metals and shear bolts were the talk of the day recently, when Steve Lewis from ECL Group visited our team.

Steve gave an awesome presentation with real-world examples of good and bad practice installation. This was an invaluable talk that our team loved - thanks Steve!

Well done to Trudy, Craig and Phil from JA Russell for cooking up a storm, with a BBQ breakfast for the team while we listened.

A huge thanks to Judith from the Little Cherry Coffee Cart for the hot beverages. A great way to kick off the day! ☕

Have you ever wondered how thermal imaging works? 🔥🌡️

Thermal imaging technology captures the heat or thermal radiation emitted by objects.

Using thermal imaging cameras, we can detect the infrared radiation given off by electronics, electrical systems and manufacturing production equipment.

This radiation is then converted into a ‘thermal map’ of the scene – an image that shows temperature differences.

Thermal imaging is key in helping us detect faulty components and isolating issues quickly and safely – with minimal downtime to your operations 💪

At Hennessy, we continuously seek ways to improve what we do, and be more efficient and accurate in our approach.

Our engineering and automation team recently transitioned to using EPLAN - a world leading software solution that connects every stage of the engineering process together, from pre-planning to project planning to design.

EPLAN enables us to produce cleaner, more detailed drawings and reports in a fraction of the time, improving efficiency and accuracy 🎯

Using EPLAN, our designers can prioritise designing, with EPLAN handling the task of translating those designs into comprehensive drawings.

For our clients, this transition means projects are executed with more precision and speed, ensuring a consistently high-quality result.

We’re proud to work alongside Waitoa Industrial Estate, using our experience and capabilities to help them streamline and optimise their operations.

Check out our latest project - designing and implementing a user-friendly, site wide control system for the entire wastewater treatment plant.

We’re especially proud of the process alarm notification system - this system immediately alerts operators about areas of concern and gives them the ability to tap in remotely to isolate and address critical issues.

The fully customised system features an automatic Dissolved Air Floatation (DAF) plant, four new treatment lagoons with integrated aerators and mixers, an automated Bio-Solids removal plant, variable speed drives, PLC equipment, and a 3200amp MCC/Switchboard that integrates with existing systems.

This scalable system can grow as Waitoa’s demand grows, helping prepare Waitoa Industrial Estate for a solid future.

We recently completed the Altus OMAV extrusion line installation - and this project certainly had it all! From a rapidly changing timeframe, to international suppliers, equipment delays, multiple on-site contractors, and sourcing materials at short notice.

We believe in channeling energy into finding solutions, and for this project that meant deploying staff and resources at critical and often tight lead times, and staying flexible and using foresight to ensure the equipment was fit-for-purpose.

Taking an experienced and agile approach, our team worked alongside the mechanical installers and key providers to plan, design with future needs in mind, and execute the build of the 20MN press to an ambitious schedule, with limited downtime for Altus’s extrusion line.
