Chalet and Greffisol (Mumbai)

Indian innovator Greffisol is partnering with Chalet Hotels Group to pilot a cooling tower solution that accommodates height restrictions from a major airport adjacent to the Marriot Sahar hotel. The forced-draft cooling tower was produced by Evapco, a US-headquartered company with global operations, and features energy-efficient centrifugal fans with custom-made louvers, guiding vanes, and distribution planes that aim to reduce the cooling tower approach from 4.5 to 2.7 Celsius. The pilot seeks to reduce energy use and greenhouse gas emissions by 15 percent and operating costs by 25 percent.
