Vacuum ovens are ideal for removing residual water, solvents or other volatile compounds from temperature-sensitive products. The principle of operation, essentially, is to remove unwanted molecules by lowering the pressure in the oven (creating a vacuum). When the oven pressure reaches the desired vapor pressure of the contaminants, these contaminant molecules evaporate, turn to vapor, and are removed from all areas of the product. This drying is accomplished without the use of excessive heat. This makes vacuum drying suitable for materials that become damaged or are changed if exposed to high temperatures. Vacuum drying also minimizes the risk of scaling and the formation of oxidation residues. Vacuum high temperature ovens are typically used for products that are not heat resistant and are temperature sensitive. This type of oven is widely used in semiconductor, MEMS, electronic area.
