Utilizing a process of tightly controlled radiant heat, PIPE DEBONDER breaks the original cement bond by softening the pipe in the fitting. First you set the size and schedule of the pipe on the controller and press START. PIPE DEBONDER automatically runs the appropriate heating cycle. That cycle is microprocessor controlled with pulse width modulation to provide the ideal declining heat for each variation of PVC and ABS pipe. At the end of the cycle the controller beeps. You then use the Debonder Extractor to remove the broken pipe, leaving the fitting cool and undamaged.
