Lab Heating and Drying Ovens

In a gravity convection oven, the temperature distribution is based on warm air moving upwards (see above). There is no fan that actively distributes the air inside the chamber. The benefit of this technology is very low air turbulences for gentle drying and heating.

In a mechanical convection (or forced air) oven an integrated fan actively moves the air inside the chamber – resulting in an even temperature distribution throughout the chamber (see above). One benefit is optimal temperature uniformity for reproducible results, for example in material testing and for drying protocols with very tight temperature requirements. Another advantage is a much faster drying process compared to gravity convection. When opening the door, the temperature will recover faster to the set temperature level in a mechanical convection oven.
