Description

APPLICATION
The Geer type Oven is widely used for evaluating thermal aging of plastics and rubber by the oven method.
There are many kinds of thermostatic chamber generally known as the “oven”. Problems have often been encountered in use of these ovens – if these ovens which differ in their mechanisms were used carelessly, the results of testing differ very widely.
TOYO SEIKI’s Geer type Oven has been especially designed and manufactured exclusively for aging tests and not as an ordinary drier or thermostatic chamber. Important factors such as temperature control precision, temperature distribution, temperature recovery after opening the door, air speed inside the oven, air change rate and sealing mechanism of the intermediate chamber, etc. have been fully taken into consideration in designing and constructing this Oven.
