Our team diagnosed internal errors on legacy variable frequency drives and replaced them with high-efficiency Optidrive E3 units to restore full control over the pump systems. We also performed detailed testing on the Marathon Electric motors and updated the electrical panels with new Square D circuit breakers to ensure the mechanical room operated at peak performance. During the installation. These upgrades stabilized the facility's mechanical operations and provided a more reliable and energy-efficient filtration system. Our work focused on replacing worn components and improving the long-term durability of the entire mechanical room infrastructure.
