Vacuum ovens are ovens designed for temperatures up to 200 degrees Celsius. The inner chamber of the vacuum ovens is made of stainless steel. Vacuum furnaces designed for temperatures up to 1000 degrees Celsius. A vacuum oven is designed for various uses in laboratories, and research institutes to dry and heat objects in a vacuum environment.
-The oven is primarily used for desiccating, vacuum embedding, plating and electronic component processing
Applications Vacuum ovens:
The use of vacuum ovens is in the following cases:
-Removal of bubbles, for example from epoxy castings, coating with epoxy layers or varnish.
-Flammable materials or bombs like solvents, oxygen removal prevents fire ignition. The solvent that comes out of the oven can be taken out into the air or recycled in a cold trap that is between the oven and a vacuum pump.
-Drying liquids from porous materials It is difficult to dry them.
-Low down the drying temperature so as not to damage the components of the material
* For example, when drying food so as not to damage the ingredients of the food, dry in a vacuum oven.
* For example, when drying cannabis with ethanol, work with a vacuum oven that does not harm the active plant substance extracted from the cannabis.
* For example when drying plastic or other materials that may be melted.
Choosing a vacuum pump for a vacuum oven:
Select a pump according to the required vacuum depth, the desired pump capacity is 3 times the volume of the oven, if the volume of the oven is 50 liters, a pump with a flow rate is desirable. Of 150 liters per minute. The lower the flow the longer it will take for the oven to reach the desired vacuum. Depending on the process an oil pump, an oil-free pump and a chemical-protected pump should be chosen.
Vacuum Furnaces / Vacuum Ovens
Working in a Vacuum Oven can:
-Avoid reactions such as oxidation or decarburization.
-Remove surface contaminants.
-add a substance to the surface layers of the work.
-Removal of contaminants by degassing.
