Visitors stand around a large ThermoKey dry cooler with angled copper headers, flanged connections and a "FAN MOTOR CONTROL BOARD" cabinet with warning labels. In the foreground a stainless unit with a fan guard and the marking "FULL BELL MOU..." is visible, under the blue ceiling structure of the stand.
