ABSTRACT:
The present invention relates to the technical field of fluid heater devices, and more particularly to an electric immersion heater for use in electro-plating, metal preparation, finishing applications in the electronics industry (e.g. preparation of printed circuits). The invention more specifically provides a new and improved electric immersion heater design that includes, in combination, a unique flexible cable structure enabling small diameter coils (made primarily from a fluoroplastic material) which, in turn, are mounted on a support frame structure. This provides an inexpensive heater assembly that has optimum heat transfer capability in liquid treating mediums.
