At Huber, we help our customers overcome their challenges through our knowledge and experience in stopper processing





Washer, sterilizer for rubber stoppers and rubber articles of the 
pharmaceutical and technical elastomer industry.


Used also as an Autoclave to sterilize metal parts for aseptic 
manufacture, filters and porous goods, etc.

The Model HWS is a hybrid pharmaceutical quality autoclave with stopper 
washer sterilizer capability. The Direct Impact Cleaning drum with CIP/SIP 
assembly is inserted into the center of the autoclave for use as a dedicated 
stopper processor. The insert can be removed for use as a standard 
pharmaceutical autoclave (as shown below). 


The pressure chambers and pressure vessels are manufactured in 
Switzerland. The Swiss factory has robotic welding and x-ray capabilities 
as well as orbital clamp welding machines for the pipe work. 

The Swiss factory is ISO 9001 certified.

The stopper processor capacity ranges from 100 liters to 250 liters. 
The pressure chamber volumes range from 1080 to 1800 liters. 
The pressure vessel is designed according to ASME code, 
PED97-23-EG (Pressure Equipment Directive), Regulation Rules AD2000
and other codes. 

The HWS has several process control alternatives

SAIA PLC with WS 8450 
- which consists of a PLC, PC with 
color screen, keyboard and color printer. 

Allen Bradley LOGIX - which consists of a PLC, PC with color
screen, keyboard and color printer. 

Because the drive is outside the autoclave chamber and 
      the seal meets all sections of the most stringent hygiene
      requirements of the FDA, no metal abrasion is possible 
      inside, as with gear drives.

Only this mechanical seal meets the current FDA 
      requirements and guarantees sterility during pressure 
      and vacuum including leak test. 

There are no mechanically moving parts during the process, 
      and no metal abrasion, only highly cleaning turbulence 
      of DIRECT IMPACT CLEANING, washing each stopper


Optimal temperatures during each process step, max. 
      uniformity of temperatures during sterilization by patented 
      system of steam inlet and distribution.

Effective vacuum drying with immediate removal of water 
      drops from deep holes through occasionally  
      intermittent shifting of stoppers (patented) providing
     uniform low residual moisture.

Loading from non-sterile side. Ergonomic unloading at 
     sterile side, even into containers for direct transport to 
     stoppering machine.

Anti-pyrogen piping of "no weld techniques' and valves.

Anti-pyrogen walls of inner drum, mirror finish.

Machine design complying with GMP, WHO and FDA 
     standards, as well as YOUR requirements.

bulletCIP high-pressure machine self cleaning system (Patent) 
guarantees releasing and immediate flushing of pyrogens.
bulletCIP system (Patent) guarantees total cleaning of the inner 
drum including inner walls of outer cylinder and because of that,
reproducible cleaning values.
bulletCIP system (Patent) guarantees processing of siliconized and 
non-siliconized stoppers without carry over.
bulletSIP Steam In Place (Patent) for precise vaporization of 
machine inner surfaces through rotating steam nozzles.
bulletSIP system (Patent) reduces non-productive times, increases 
productivity and eliminates recontamination and cross-contamination.

The ideal combination of a stopper washer, sterilizer and
autoclave in one hybrid unit with great flexibility.
