Baldor-Reliance® Cooling Tower Direct Drive (CTDD) reduces energy usage and maintenance costs for facility in Pune, India.


Fort Smith, AR, February 9, 2022 -- Heating, Ventilation and Air Conditioning (HVAC) consume an average of about 50 percent of the energy in buildings. By installing ABB’s Baldor-Reliance® Cooling Tower Direct Drive (CTDD) solution in its hotel, JW Marriott Pune, an iconic landmark in the city of Pune, has set new benchmarks in energy efficiency, saving about 35 percent energy annually. Energy saved in a day with ABB's direct drive solution can charge an electric car to run for approximately 1500 km.

  • CTDD replaces the gearbox, driveshaft, and induction motor typically used to drive cooling tower fans
  • With a return on investment in less than two years, the solution ensures quieter, and maintenance-free operation

cooling tower is a key component of many refrigeration systems and can be used to provide comfort cooling for large commercial buildings like airports, schools, hospitals, and hotels. Energy is consumed in driving the fan, or fans, necessary to achieve proper air movement through a cooling tower. ABB’s direct drive solution offers the benefits of variable speed control and eliminates the cost and maintenance required for traditional gearboxes or belted solutions. The fan couples directly to the motor and is controlled by a unique AC drive to provide optimal speed and cooling tower performance that runs quieter with reduced energy consumption. The solution also provides a Quick Start Assistant, making start-up simple and straightforward.

“When we aim to reduce energy consumption, every possible way to conserve energy must be evaluated, and the most energy-efficient technologies and practices must be implemented. Buildings offer huge scope in energy optimization and have a great potential in shaping our sustainable future. Investing in energy-efficient technologies can bring both economic and environmental benefits,” said Sanjeev Arora, President, Motion business, ABB India.

“Sustainability has always been an integral part of our operations, and our goal has been to help customers in extracting greater value from the energy they use” he added.

World over, buildings consume over 30 percent of the global energy consumption. For half a century, ABB has been leading the way in optimizing HVAC systems in buildings, using drive control technologies. The group actively contributes to a more sustainable world, leading by example in its own operations and partnering with customers and suppliers to enable a low carbon society, preserve resources, and promote social progress.
