Hennessy knows lost production equals lost profits, so finding, isolating and repairing faults is a critical task.
Our technicians undertake thermal imaging to detect faults quickly and safely, without interrupting operations. Thermal imaging can also identify areas of concern before they become faults and inform preventative industrial electrical maintenance plans to avoid plant or production breakdowns from occurring. We also maintain Radio Telemetry for Remote control of plant as well as Data & Wifi network systems.
