INVT’s elevator modernization and retrofitting solution simultaneously upgrades the control system and implements energy-saving modifications, providing old elevators with advanced functions such as energy feedback in a one-stop manner. Adopting a universal commissioning method, it significantly lowers the retrofitting threshold and shortens the project cycle.
Old system is outdated with high failure rate.
High elevator energy consumption and electricity costs.
Retrofitting and energy-saving modifications require separate implementation.
New system commissioning is complex and requires learning.
Long elevator downtime during retrofitting causes significant impact.
Traditional retrofitting offers single-dimensional value.
Long payback period for energy savings.
Post-retrofit maintenance costs remain high.
This solution adopts INVT’s integrated control and drive platform. While upgrading the old control system, it directly integrates the energy feedback unit, achieving “one retrofit, dual upgrades.” The solution features a universal commissioning interface and method, allowing engineers to get started quickly without additional training, significantly reducing construction time and minimizing disruption to elevator operation, while comprehensively improving elevator performance and energy efficiency.
View Larger ImageOne Retrofit, Dual Benefits: Single hardware replacement achieves both system upgrade and energy-saving integration.
Ready-to-Use: Pre-configured universal commissioning parameters and wizards eliminate the need for new learning, lowering the technical barrier.
Energy Feedback as Standard: After retrofitting, the elevator directly gains the ability to feed electricity back to the grid, turning consumption into return.
Modular Replacement: Complete modular replacement of the old system enables fast construction and high reliability.
One retrofit improves both reliability and energy efficiency (energy feedback saves 20%-40% electricity), with dual value accelerating investment recovery.
Universal commissioning shortens project duration by approximately 30%, reduces elevator downtime, and minimizes impact on users.
Engineers can complete commissioning with existing knowledge, requiring no additional training and saving labor and learning costs.
Old elevators achieve new-elevator standards in stability, ride comfort, intelligence, and energy efficiency, significantly increasing asset value.
The new system features remote monitoring and early warning functions, shifting from reactive maintenance to proactive maintenance, reducing long-term operating costs.
