An oven made by FOURS GUYON is characterized by its originally developed heating system, using fireproof bricks that can quickly bake up products and can be used economically as an energy-saving oven. It was developed based on the concept of thermal conduction in the traditional stone oven where heat is stored in bricks and natural stone and keeps temperature evenly throughout the entire oven to increase thermal efficiency. It is an oven developed for professional bakers, which increases production efficiency while maintaining product quality as it is.
