All Prometec storehouses-ovens are manufactured with prime materials.

A better insulating system gets a lower loss of heat such as low power consumption. Our air distribution hoods (a characteristic Prometec device) have been designed to obtain a faster and more uniform flow of the air with the same installed power. The internal walls of the storehouse have got particular slits, placed at the same height where the slabs will lay, this allows to homogeneously flow the hot air both towards the platforms and along the stone material.

Each Prometec oven, both drying and hardening type, is equipped with a humidity/vapor extractor which checks the level of humidity keeping it constant.
