The typical operating temperature of the tunnel is 320° C. At this temperature it takes 9.5 seconds to reduce the bacterial endotoxin level by 1-log. A 4-log reduction will take 38 seconds, and a 6-log reduction in bacterial endotoxin 57 seconds.

Heat is generated by silicon controlled rectifier (SCR) heating elements. Depending on the format, vials stay inside the sterilizing/depyrogenation chamber for approximately 6-10 minutes. The recirculated hot air is blown at a speed of approximately 0.7 m/s over the vials and remains within 2°C of its setpoint.
