Property developer's son branched out into manufacturing in 1988 by borrowing $1,500 from his father. Today his Symphony, in which he owns a 75% stake with family, is the world's biggest producer of air coolers, or what he calls "the common man's air conditioner." It sells 1 million units annually in 60 countries. Symphony air coolers are used in such places as the walkways at Heathrow Airport, Wal-Mart stores and temples in India. Seeking expansion, Bakeri bought Munters Keruilai, a Swedish-Chinese joint venture to gain access to China and the Asean region. Assets include the family's real estate holdings in and around Ahmedabad city.
