DEPYRO_TUNNEL_CTRL
Depyrogenation tunnel hot-zone temperature control with accumulated FH lethality and a release permissive.
When to use it
Use DEPYRO_TUNNEL_CTRL when glass containers pass through the hot zone of a depyrogenation tunnel on a belt, and the delivered dry-heat lethality has to be computed from the zone temperature and belt speed before the containers are released to filling.
