The fact that the seal works in the way it does minimises heat loss and provides insulation, this can save massively on running costs as-well maximise the ovens potential.


Safety is another reason industrial oven door seals are used and tested in the way that they are. In all industries ovens are requires to be started and operated by humans. Although ovens are locked and sealed during processes people are required to be in close contact with them.
