Resistance element for defrosting evaporators in refrigeration units

摘要

A resistance element for evaporators in refrigeration units comprising a resistive wire (4) surrounded by a layer of dielectric material and housed in a sheath (6) of heat-conducting material, to the ends of the sheath there being applied at least one temperatrue limiting element (12) and one temperature regulating element (10), characterised in that said elements have their sensitive part in contact with the sheath and are surrounded by a block of heat-insulating material.
