BOROSILICATE GLASS
Inner Doors for Pyrolytic Ovens
The main application of ELECTA Borosilicate Glass in the appliance sector is the production of inner doors for pyrolytic ovens.
The pyrolysis process allows for the carbonization of all grease residues generated inside the oven cavity during food preparation. This is achieved by raising the temperature inside the cavity up to $500^\circ C$ and maintaining it for cycles of 1.5 to 2.5 hours.
The glass component is therefore required to withstand these temperature conditions and maintain its properties over time.
ELECTA Borosilicate Glass is the raw material with the best characteristics to fulfill this function among all glass types.
For this reason, borosilicate sheets are used to produce oven doors in 60 cm and 90 cm formats (e.g., for the USA market or the professional cooking sector).
Borosilicate glass can be transparent or subjected to silkscreen printing. The silkscreen printing process on borosilicate glass is particularly delicate and has been refined by ILVA Glass over the past 10 years during product development. The same applies to the thermal treatment process of the finished component, which imparts special characteristics of resistance to temperature and mechanical shocks.
Inner Doors with Heat-Reflecting Coating
Inner doors with a heat-reflecting coating are oven doors to which a pyrolytic infrared reflecting filter is applied, which achieves two fundamental results:
1. A significant increase in the oven’s energy efficiency: The coating acts as an infrared barrier, which reduces heat transmission between the cooking cavity and the outer door.
2. A drastic reduction in the temperature of the outer door, especially during pyrolysis processes.
This high-efficiency coating makes it possible to have “cool” outer doors below $35^\circ C$, even when the internal temperature reaches $500^\circ C$.
Temperature Control
ILVA Glass’s experience and know-how in the field of oven glass layering allow for the development of low-emissivity solutions for both pyrolytic and conventional ovens, finding an appropriate balance between efficiency and heat insulation for every project.
