Hold the Steam: Dry heat sterilization systems use forced-air convection technology for reduced energy consumption.

Pharmaceutical, Medical Device and Life Science Research sterilization has recently seen a demand for greener technologies that require less maintenance. This puts the pressure on equipment engineers to develop innovative ways to approach sterilization. While traditional steam autoclaves use water; dry heat sterilization provides an alternative to steam that uses no water, less energy, and requires less maintenance.

Compared with steam sterilization; dry heat sterilization is a greener technology that eliminates water usage, provides more flexibility for installation locations, and costs less to own and operate.

Modern dry heat sterilization systems using focused forced air convection technology are consistently decreasing the cycle time. Depending on the load configuration and cool down requirements, the typical cycle lasts less than 3 hours.

The initial cost of available dry heat sterilizers is about 60% of equivalent sized steam autoclaves. A dry heat sterilizer is two to three times lighter than an equivalent steam system. Because the dry heat sterilizer can be rigged in place as modules, there are considerably less rigging challenges and costs. The dry heat sterilizer does not need to be pit mounted.
