The present invention is directed towards a removable heat exchanger for a fabric treating machine. The machine generally includes a perforated spin tub and an imperforate outer shell. In one embodiment the heat exchangers, which are removably mounted to an inner surface of the outer shell, are guided during installation and removal by guide clips. Spacers maintain the heat exchangers a predetermined distance from the inner surface of the outer shell. Retainer clips are provided to releasably retain the heat exchanger in position relative to the spin tub during operation of the machine. In a second embodiment the heat exchangers, which are mounted within side pockets provided by the outer shell. In both the first and second embodiments, the heat exchangers are held in place by jacking bolts. The removable heat exchanger of the present invention improves upon welded-in-place internal heat exchangers and external heat exchangers.

Removable heat exchanger for industrial laundry machines

An enzyme bath maintenance system is provided for use in such textile treating fields as stonewashing, laundry, cleaning and dyeing, including the use of enzymes as the active agent, in which the enzymes are utilized within narrowly controlled ranges of pH and temperature. As a means for providing heat for controlling the temperature, a heat exchanger in which the heat source is hot water at a temperature not more than 12.degree. C. higher than that of the desired temperature, is disposed within the apparatus. The heat exchanger and the apparatus as a whole are designed to avoid pockets which allow the enzyme to become entrapped therein. The apparatus further includes automated means for detecting, monitoring and reporting bath parameters such as pH and temperature, with output for manual or automatic control thereof, and means for agitating the enzyme bath to maintain uniform distribution of the enzyme.
