Abstract: The present invention discloses a control box for enclosing at least one main control circuit electrically connected to at least one or more electrically-controllable function providing operating units mounted through or operably connected to a jetted tub. The control box in general comprises a high voltage compartment and a low voltage compartment, separated by a partition having at least one access opening to permit electrical connection of at least one control unit to a high voltage terminal block installed in the high voltage compartment. Another aspect of the present invention concerns a control system for use with the jetted tub having one or more function providing operating units electrically connected to the control system. The control system comprises a control box having high and low voltage compartments separated by a partition.

Abstract: A rotary compression bending machine comprises a radius die, a wiper die, and a flexible ball mandrel. Hydraulic cylinders are provided to simultaneously drive the wiper die around the radius die and to draw the ball mandrel through the tubing in order to reform the tubing while bending. The reformed tube will be wrinkle and distortion free around the bend radius.
