Abstract: The invention describes a tank comprising a solution, dispersion or emulsion for selective catalytic reduction in combustion engines. The tank comprises an electrical resistive heating element immersed in the tank. The electrical resistive heating element comprises at least one heating cord. The heating cord comprises metal filaments. The metal filaments •comprise a copper layer or a layer in a copper alloy, and comprise a surrounding layer in stainless steel, •or comprise a steel layer, surrounded by a layer in copper or in a copper alloy, surrounded by a nickel, zinc or tin layer or a layer of alloys comprising such metals; •or comprise a layer of low carbon or high carbon steel, and comprise a surrounding nickel, zinc or tin layer or layer of alloys comprising such metals, and the heating cord comprises a polymer coating layer.

Abstract: The invention describes a tank comprising a water or solvent based solution, dispersion or emulsion. The tank comprises an electrical resistance heating element immersed in the solution, dispersion or emulsion. The electrical heating element is provided in the tank with an electrical current. The electrical resistance heating elements comprises a textile fabric and at least one electrical heating wire. The electrical heating wire is fixed onto the textile fabric and the electrical heating wire comprises metal filaments or metal fibers.
