SED-24000RXG-D — Ampoule Tunnel Dry-Heat Sterilization, Depyrogenation and Cooling Oven

Washed ampoules are transported by a 600 mm-wide stainless-steel mesh belt (speed 50–350 mm/min). In the preheat zone bottles are gradually brought up to temperature under Grade A (100-level) laminar hot air. In the high-temperature sterilization zone, electric-heating elements generate heat which is circulated by high-temperature-rated hot-air fans through HEPA filters, maintaining a uniform ≥302 °C for ≥5 min (heat distribution ≤±5–8 °C both no-load and full-load) to achieve FH > 1,365 and >3 log endotoxin reduction. In the cooling zone, circulating air passes through a water-cooled heat exchanger (chilled water 7–12 °C, flow 15–30 m³/h) to cool bottles to ≤35 °C (or ≤ambient + 5 °C) before exit into the next process step. Touch-screen PLC control with automated monitoring, alarm logging, trend displays, and multi-level user permissions.
