摘要

a) The invention relates to a heating resistor such as immersion heater with built-in regulating and safety devices, especially for explosive atmospheres, and fitted with a leaktight dissipator package forming a casing and heater means thus equipped; b) The resistor is characterised by one or more heating resistors 2 fitted with a thimble 3 arranged amid the heating pins, with a means of connection 4 to a heater vessel, with one or more cooling means 5 for the resistors 2, with a leaktight dissipator package 6 forming a casing arranged on the outside part 7 of these resistors and imprisoning at least two internal 8 and external 9 supports embedded, together with their electrical connections 10, in a synthetic material 11, each support 8, 9 including a set of means for control, regulation, safety, timing or the like, in that the external support 9 receives, on the front face and outside the synthetic material block 11, a panel 12 for control 13, display and alarm 15, in that this panel 12 includes a transmission for control 13 with no electrical connection, and in that the package includes one or more means of supply or of ancillary control; c) The invention applies in general to apparatuses for heating baths and fluids usable in explosive atmospheres.
