Subzero is a hydraulically driven unit which offers automatic tube expansion of boiler tubes to come over the limitation of conventional tube expansion method thereby offering attractive saving in labor, time & money. Because of its drastically reduced weight and size the drive head can be maneuvered easily inside confined spaces such as drums. Jobs are competed faster with far less manual labor, less operator fatigue.
