摘要

The temp. in a fabric treatment vessel is maintained by a fan driven by a variable-speed motor according to the readings of a thermal sensor. The fan draws the steam/air mixture through a heat exchanger for recirculation to keep the steam/air mixture at a constant level below the boiling point of the treatment fluid. The system prevents unwanted condensation which would weaken the concentration of treatment bath.
