Electric threaded immersion heaters - industrial kettles and boilers

In boilers or hot water storage tanks, a threaded connection to the same tank is always provided for the installation of the electric heater which acts as an aid/integration for the water heating part.

Depending on the volume of hot water needed by the system, a tank model is defined with relative connections for the heater to be installed.

With the size of the external diameter of the tank, the electrical power needed, the supply voltage and the connection diameter provided for the heater, Reart is able to define the main characteristics of the threaded heater to be inserted on the tank.

The main features of the threaded heaters produced by Reart are the following:

Where small powers are required, the heaters are on small threaded connections. With the necessary increase in electrical power (given the volume and size of the tank) to be installed on the heater, the coupling size of the heater will necessarily increase in order to always keep the surface heat exchange load of the heater at controlled parameters to ensure good and long operation life to the electric heater.

Normative requirements:

  • 2014/35/UE “Electric Material in Low Voltage”.
  • RoHS 3 Directive 2015/863/UE
  • REACH Regulation 1907/2006/EC

In addition, it is possible to supply heaters with threaded connection for industrial boilers and boilers, with the following accessories:

  • Power cable incorporated into the heater (suitably sized according to the electrical parameters).
  • Shuko connection for single-phase 2 + T cables.
  • Power and safety cable glands on board the electrical connection enclosure.
  • External surface treatment of the electric beam (electro-polishing).
  • Any galvanic anodes in Magnesium.
  • Indicator light (heater in operation).

The electric heaters with threaded connection for industrial boilers and boilers are customized/customized also upon request and specification of the customer.
