Understanding Vacuum Ovens

Vacuum ovens provide a highly efficient method of extracting excess moisture from a material by utilizing the combined effects of high temperature and low pressure. By reducing the pressure around the material, increased evaporation occurs at lower temperatures. When drying is performed at higher temperatures, lowering the pressure allows for faster evaporation. 

 

Vacuum ovens control the set temperature while a vacuum pump reduces the pressure in the oven chamber. These systems are commonly used for drying and curing processes in various industries, including pharmaceuticals, paper, ceramics, and rubber. In addition, vacuum ovens play a critical role in botanical extraction.

Factors to Consider When Selecting the Ideal Pump for Vacuum Ovens

  • Chamber volume  
  • Desired ultimate vacuum
  • Vacuum control options
  • Chemically resistant
  • Oil-free operation
  • High vapor and condensate compatibility
