How is cooling temperature controlled?

Recirculating laminar air through chilled water coils discharges vials below 25°C.

What drainage is required at the installation point?

A floor drain sized for the peak discharge rate is required adjacent to the machine, with an air break to prevent back-siphonage. The utility schedule supplied with the machine gives the exact flow and connection sizes.

What warranty applies to this machine?

Machines are supplied with a 12-month warranty from commissioning covering manufacturing defects, with wear parts and tooling excluded. Extended cover is available under an annual maintenance contract, which also fixes response times for breakdown attendance.

What documentation is supplied at handover?

Handover includes the operation and maintenance manual, electrical and pneumatic schematics, the spare parts list with part numbers, material test certificates for contact parts, sensor calibration certificates and the completed qualification dossier.

What water quality does the machine require?

Final rinse requires Water for Injection or Purified Water depending on the dosage form, supplied at the specified pressure and temperature. Earlier rinse stages can run on potable or purified water, and the machine records the conductivity of the final rinse.

How is cleaning effectiveness demonstrated?

Effectiveness is demonstrated during performance qualification by riboflavin coverage testing, followed by swab and rinse sampling against the residue limit calculated for your worst-case product.

Overview

About the DST-300 Continuous Depyrogenation & Sterilizing Tunnel

The **DST-300 Continuous Depyrogenation Tunnel** is designed to sterilize and depyrogenate pharmaceutical glass containers entering aseptic fill-finish suites. Operating at temperatures up to 350°C, the tunnel features pre-heating, hot-air sterilization, and cooling zones under Class 100 laminar flow.

Dynamic Air Pressure Cascade Management: Active differential pressure transmitters maintain positive Grade A pressure.

Recorded Final Rinse Conductivity: Final rinse water quality is measured and written to the batch record, giving objective evidence that the cleaning cycle completed to specification.

Validated Cycle Recipes: Wash, rinse and dry stages run to stored recipes, so the qualified cycle is reproduced exactly on every load.
