Episode 98: The heat exchanger
It weighs about two tons and measures two metres by one, and a half metres in diameter. The imposing nature of Técnico’s heat exchanger does not go unnoticed in the main atrium of the South Tower, at Alameda campus. It is, in fact, half of a heat exchanger, which was cut in half and is exhibited for teaching purposes, displaying its 224 tubes and a floating head. Despite its invention almost a century ago, it is still today a fundamental instrument in the history and practice of industrial chemistry.
