Heating Elements for electric ovens

Applications:

Heating elements transform electrical energy in heat and are widely used in most of domestic  and commercial electric appliances to heat water, liquids and air.

Thermowatt operates in the cooking appliances sector with a wide range of tubular heating elements designed and customized to meet Customer requirements. These heating elements are produced in stainless steel and are used in electrical ovens and grills.

 

The external tube has a key role in disposing of the heat to the outside to ensure the long life of the product. The operating environment does not produce corrsive effects so the choice of steel depends on the temperatures reached. In the range of heating elements for cooking, the choice of materials is also geared toward food use in accordance with the sector reference standards. The sealinf systems adopted always guarantee proper electrical insulation and an excellent performances even at high temperatures.

SICUT is a Thermowatt technology used for sealing the heating element to be used in cooking appliances. It is based on the use of a conic cylinder made up pf Teflon which is pressed between the electric terminal and the sides of teh tube element. Deep in the tube the Teflon cylinder is also pressed against the magnesium oxide to avoid small pit that can hold humidity. This technology significantly improve the performances of the heating element against the absorption of humidity.

The absorption of humidity of heating element is one of the main reasons that cause heaters to short circuit when the oven is first turned on, since the finisched goods are held in storage for long periods.

SICUT sealing technology ensures good performances during operation thanks to the heat that soften the sealing parts. This allow the heaters to “breathe” making them more reliable. Moreover, this technology protect the heaters against bumps and handling during production or installation. The use of Teflon cylinder guarantee the minimum distance between the electric part and the external tube in accordance with prevailing regulations on electric insulation.

UPPER ELEMENT + GRILL: The heating elements used in the top of the oven generally comprise the upper and grill elements, characterized by two different methods of cooking in the oven. These two heating elements are frequently manufactured and assembled on the same support (flange) as a single product.

The upper heating elements have a specific surface load of 3-4 W/cm2 and the specific surface load of the grill heating elements is 5-6 W/cm2. These values determine the working temperature of the heating elements and are fundamental in the choice of materials to be used in the internal spiral and of the steel of the external tube.

BOTTOM ELEMENT: The heating elements used in the bottom part of the oven casing work at low electric power and a single heating element is used. Typical values of the surface load are between 3-4 W/cm2. The geometry of the elements generally reflects the lower part of the oven casing to favour the natural convection of the air inside.

VENTILATED OVEN: The heating element has round shape and follows the air blowing profile of the fan.

The choice of suitable materials, the use of standardized manufacturing methods and rigorous products controls allow Thermowatt to ensure an excellent level of quality and reliability of its products using mass production processes as certified by the most prestigious international institutes as VDE, UL,IMQ.
