Product Introduction

The pharmaceutical pass-through autoclave mounts between segregated rooms so loads enter from one side and exit from the other only after the completed sterilization cycle. A jacketed 316L stainless chamber, vacuum-assisted air removal and clean-steam distribution support porous, wrapped or component loads. Door interlocks, loading rails and dedicated trolleys maintain separation and safe material movement across the wall boundary.

Key Features

Opposing interlocked doors prevent an unsterilized load path through the cleanroom boundary.

Jacketed 316L chamber and vacuum system support controlled steam penetration and drying.

Anti-tip rails and dedicated trolleys guide heavy loads through the chamber.

PLC control records cycle temperature, pressure and phase status for operational review.

Customer Product Concerns

Materials must cross room boundaries without bypassing sterilization or permitting both sides of the pressure chamber to open together.

Manual transfer can reconnect dirty and clean sides.Door interlocks release the discharge side only after the configured cycle completes.

Trapped air prevents uniform steam contact in porous loads.Vacuum-assisted air removal and controlled steam pulses improve chamber penetration.

Heavy trolleys are difficult to align with the chamber.Fixed anti-tip loading rails provide a repeatable guided path through the sterilizer.

Cycle deviations are hard to investigate without recorded data.PLC monitoring records pressure, temperature and phase progression for each load.
