Shore power supply makes for clean harbors

When using drive technology in a shore-supply solution, ships can source clean energy from local grids. The ship’s main generators can be switched off completely to prevent unnecessary local NOx and carbon emissions and noise pollution while the vessel is docked.

Danfoss Drives provide drives and inverters which convert the 50Hz shore power to the 60Hz power typically used onboard sea going ships. Grid converters use Active Front End AFE technology with proper software able to create and synchronize the AC-grid (micro grid) to the ship's grid.

    Engineering Tomorrow’s Movie Experiences

    Driven by a promise to engineer a better tomorrow, Danfoss Variable Frequency Drives (VFDs) were the perfect answer to PVR’s challenges. Danfoss’ plug-and-play and energy efficient FC-102 VFDs proved to be the best solution for HVAC systems across PVR’s multiplexes in India, and have delivered unprecedented results for the service provider.

  • Engineers world’s 1st solar-powered Airport for utmost passenger comfort

    At Danfoss, we are engineering a better tomorrow through technologies that enable today’s airports to become energy efficient whilst delivering uber comfort to the passengers. At the Cochin International Airport, our Variable Frequency Drives (VFD) across chillers, cooling towers, pumps and Air Handling Units (AHU) have helped optimize the energy consumption and the Pressure Independent Balancing and Control Valves (PIBCV) have helped moderate the flow of chilled water basis the number of people in the airport. Together, the VFD and the PIBCV have helped the Cochin International Airport save energy by almost 30%.
