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 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. 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.
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.
