Sterilizing tunnel 
Machine type DHT 2431
The sterilizing tunnel of the DHT series dries, sterilizes and depyrogenizes glass containers using a low-turbulence vertical air flow. The sterilizing-grade filters or integrated high-efficiency particulate air filters (HEPA filters) do not require any sealing on the air discharge side. Special hot gas filters in the sterilization zone produce a cleanroom class A atmosphere in all operating conditions (even during the pre-heating and cooling phases). The tunnels have multiple insulation layers to prevent heat loss and maximize energy efficiency.
HIGHLIGHTS
