Gruenberg Dry Heat Sterilizers

Gruenberg dry heat sterilizers are used for decontamination and sterilization of all forms of microbial life, such as bacteria, viruses, and spores. Gruenberg sterilizers use convection airflow and dry heat delivered to the items being sterilized. The heat is absorbed by the item being sterilized and eventually it reaches the proper temperature needed to achieve sterilization. Operating temperatures and times vary depending on the items being decontaminated or sterilized and what the customer is actively looking to kill, i.e. bacteria, viruses, fungi, spores, etc. For each, there are various methods to validate the efficacy.

Benefits of Dry Heat Sterilizers

  • Green operation with lower total energy consumption
  • Economical cost
  • Flexible installation and customization options
  • Validated sterilization cycles for assured results
  • Energy efficient electrical heating system
  • Easy to use controls


  • Closed system design or intake and exhause HEPA Filters for containment of pathogens
  • Data acquisition capabilities
  • Simple, easy-to-use color touchscreen controls
  • Sequential door lock system for pass through models
  • Interior chamber door lock override system for larger walk in or truck in systems
  • Variety of sizes to meet your requirements starting from small tabletop models starting at 1.25 cubic feet (cf) to large truck-in models offering 1,000cf of sterilization capacity. 

Dry Heat Sterilization News

Gruenberg is working with hospitals to prove the efficacy of dry heat sterilization on PPE and N95 masks for re-use. Click the link below to read the full press release on these efforts.


Stony Brook University recently released an article on their research into the use of dry heat ovens for disinfecting N95 masks for re-use. Pilot studies were conducted in a Gruenberg dry heat sterilizer to determine if there was degradation of the N95 masks after several rounds of dry heat treatment. Results from the testing were positive, showing that the heat treatment did not cause visible structural damage and had no effect on the straps. Click on the link below to read the full article.
