Sepak Industries designs and delivers factory automation and integrated control systems, providing scalable process automation solutions for environments ranging from pilot plants to large, multi-product manufacturing facilities. We develop control system design, PLC, HMI and SCADA solutions that are tightly aligned with process requirements - ensuring repeatable operation, stable control, traceability and clear operator interaction across the full lifecycle of the system.
Our PLC programming approach starts with the process, not the code. Control philosophy, sequencing, interlocks, alarm management and data requirements are defined in parallel with mechanical and hygienic design, allowing automation to support product quality, safety and throughput rather than simply reacting to it.
Sepak’s factory automation capability covers batch and continuous processes, recipe-driven operation, temperature and flow control, product diversion logic, CIP sequencing, utilities integration and plant-wide data visibility. Control system design architectures are designed to scale - from standalone skids to fully networked SCADA systems - while maintaining consistency, cybersecurity awareness and long-term supportability.
For regulated and high-risk environments, we place strong emphasis on deterministic behaviour and verification. Code structure, testing methodology and documentation are developed to support FAT/SAT execution and ongoing operational confidence, reducing commissioning risk and simplifying future modification.
Sepak Industries designs SCADA system architecture to give operators clear visibility and control across the production process. A well-structured SCADA system helps monitor equipment status, temperatures, flow rates, alarms, batching and cleaning cycles in real time, supporting safer and more efficient plant operation. Our SCADA solutions are designed to integrate with wider automation and integrated control systems, as well as equipment such as CIP systems, mixing systems and pasteurisation lines.
Reliable PLC programming is essential for consistent plant performance, safe operation and repeatable process control. Sepak applies practical PLC programming standards that support clear logic structure, ease of maintenance, alarm management, operator safety and smooth integration with sensors, valves, pumps and control panels. This helps ensure automation systems are robust, scalable and suited to the day-to-day demands of food, dairy, beverage and pharmaceutical production.
Effective control system design is critical in hygienic and process plants where accuracy, cleanability and product safety must be carefully managed. Sepak develops control system design for hygienic/process plants with close attention to process sequencing, temperature control, CIP integration, batching, data visibility and operator usability. Our systems are tailored to suit the production environment and can be integrated with process engineering design, stainless steel tanks and vessels and complete processing lines.
Sepak also delivers factory automation retrofits for existing plants, helping manufacturers upgrade aging systems without the cost of a complete rebuild. Retrofit projects can include PLC upgrades, SCADA improvements, sensor replacement, control panel upgrades and better integration between existing and new equipment. This approach helps extend plant life, improve reliability and support more efficient production while reducing disruption to ongoing operations.
Development of a highly specialised PLC and HMI control system to pasteurise five different products—each with unique temperature requirements, diversion logic and final outlet setpoints—within a single shared pasteurisation system. To our knowledge, this represents the first implementation of its kind in Australia.
