Heating of water and similar liquids

TYP 4206

The heating element consists of three U-shaped heating branches, which are soldered into the head by means of an Ag solder.
Each of the branches features one third of the total power. The head is equipped with a cover with gland AP 16/12, thus providing protection IP 54. Heating
elements without cover are available on request. The head is equipped with a hexagon NV65 (spanner size) and a mounting thread M 48x2 or G 11/2” for easy
installation. The heating elements are manufactured with brass or stainless steel head. The sheath of the heating branches is made of pickled copper, nickel
plated copper or stainless steel.

The heating element is intended for direct heating of water and similar liquids, with an operation pressure up to 1.0 MPa. It must be permanently immersed up to
the head during operation. In case of excessive deposition of lime scale (incrustations) on the sheath during operation, it is highly recommended to
provide water treatment – this will contribute to a longer lifetime of the element.
Connecting options:
Each branch is designed for voltage 230 V, at the model with power of 7500 W for voltage 400 V.Models with 230 V branches can be connected on single phase or
on 3x400 V. Model with 400 V branches can be connected on 3x400 V Δ.
