Rotary Sealer hm 880/850 DC-V

Brand: Hawo  |  Function: Print, AutoFont(hm880), LCD

The validatable hm 880/850 DC-V rotary sealer is used for the automatic closing of sealable pouches and reels (Sterile Barrier Systems SBS) in hospitals (CSSD) and the medical industry. Our successful classic model hm 880/850 DC-V was revised in details and adapted to the current design. The sealing process is validatable in accordance with ISO 11607-2 as well as the requirements of the therefrom resulting specifications of the Guideline for the Validation of the Sealing Process.

SKU: hm880DC-V | hm850DC-V Category:



  • Fulfills the requirements of the guideline of the World Health Organisation (WHO) as well as the new guideline of the World Federation for Hospital Sterilisation Sciences (WFHSS)
  • Validatable sealing process according to EN ISO 11607-2 and the international guidance ISO/TS 16775
  • Integrated printer
  • hm 850 K PC keyboard (optional)



The hm 850 DC-V rotary sealers have a clearly laid out keyboard display. Through this central control unit, all instrument functions and settings are clearly laid out for the user. The hm 850 K PC-keyboard (optional) makes data entry even easier. During the sealing process, the critical parameters sealing temperature and contact pressure are automatically monitored. If one of the parameters deviates from preset values, the device warns the user acoustically and stops the sealing process. The hm 850 DC-V possess a PC interface (RS232) for process and batch documentation. The sealing device guarantees efficient and reproducible packing, especially for large volumes of instruments.


Integrated Printer

The hm 850 DC-V can via an integrated printer print all normatively requested information directly onto the packaging during the sealing process (symbols according to EN 980).



The SealPeak sealing system accommodates every material – even gusseted pouches and reels. Therefore a flawless, full-area sealing seam can also be achieved with materials of varying thickness. The unique design of the hawoflex-sealing seam guarantees an optimal sealing safety and seal seam strength.



Work processes in the preparation of instruments should be as simple and comfortable as possible. That is why the unit is designed for the ideal utilization of the work area. Maintenance is reduced to a minimum; worn parts are easily replaceable. The ink ribbon change is simply carried out from the front of the device.


Safe Packaging

The correct reprocessing process of medical devices consists of the steps of washing & disinfection, packaging and sterilisation. The instruments can only be called sterilised when they are packaged before the sterilisation. The single-use (!) packaging, made from laminated poly film and a porous material (Tyvek® or medical grade paper) is permeable for the sterilisation medium (e.g. steam, plasma, Formaldehyde FO or Ethylenoxide ETO), but not for bacteria or microorganisms. Only by following this reprocessing sequence and by using professional heat sealers to seal the instruments as well as professional packaging material can the sterility up to the point of use as well as the aseptic presentation of the instrument be guaranteed.

Medical devices delivered in a sterile state should be packed to ensure that they remain sterile until the point of use. The validation of packaging processes is crucial to ensure that sterile barrier system integrity is attained and will remain so until opened by the users.

The international packaging standard ISO 11607-2 as well as the Technical Specification draft ISO/DTS 16775 explain how packaging processes should be validated. The international packaging validation guideline gives guidance how to validate packaging processes. During the validation of the heat sealing process the optimum sealing temperature of the packaging materials used has to be evaluated and established. At this temperature, the process then has to deliver optimum seal seams that are strong enough and peelable.

Professional heat sealing equipment for closing sealable pouches and reels (preformed sterile barrier systems) are essential for this. Hawo therefore offers sealing devices whose processes can be validated according to ISO 11607-2, the Technical Specification draft ISO/DTS 167751 and in harmony with the international packaging validation guideline. The models marked with ‘V’ feature an integrated function for regulating and monitoring process parameters – the ‘V’ is the key! Sealing devices from Hawo therefore guarantee efficient and reproducible packing, even for large volumes of instruments.
