Petro Oxo Nusantara continues to develop to support the sustainability of the factory's operating performance. One of them is the application of TFM (Topsoe Furnace Manager) technology from Denmark where PT Petro Oxo Nusantara is the first company to implement this technology in Indonesia. This TFM technology is Reformer's monitoring technology that can provide data directly to field operators. Previously, operators had to carry out inspections manually by making direct contact with the high-temperature Reformer, with this technology, it will make it easier for operators to monitor the performance of the reformer which also has an impact on increasing work efficiency and minimizing the level of danger in the work environment.
