This was a complete solution to the aging units rendered unusable due to parts and components unavailability and lack of OEM support developed by Sys Infra’s R&D team to revive, rejuvenate and with additional features. The smart solution by our R&D team comprises of various control units having the state of the art fast micro-processor and the best of components available, making the PMS working even better than before. These components developed are in modular form to address the specific issues, rather than a single replacement, thus providing the most cost-effective solution. To further enhance the cost-effectiveness,we always try to repair the existing components, which is possible due to our deep technical knowledge, in case the components are beyond commercially viable repair, we use the specially developed replacements which add further value to the main unit.
