Gravity / Natural Convection Ovens

A Gravity Oven may be the best choice for you depending on your application. Unlike a mechanical convection oven where air is pushed around by fans, hot air in a Gravity. Oven is circulated by natural convection. If you have lightweight materials or powders, a Gravity Oven will prevent the materials from blowing around and allow them to be heated fairly evenly. A Gravity Oven can also be an Economical Alternative for Basic Industrial Uses such as Drying or Baking. Perforated stainless steel shelves allow the heat to circulate freely throughout the chamber.
