Rotary Sealer hm 780 DC/DC-V

Brand: Hawo  |  Function: Print, AutoFont, LED

The hm 780 DC-V rotary sealer accomplish the sealing of sealable pouches and reels (Sterile Barrier Systems SBS) in healthcare facilities. 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. Due to a rotary speed of 10 m/min they are ideal for a high volume of instruments

SKU: hm780DC | hm780DC-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 with FontMatic
  • Interfaces for external tracking systems (e.g. ProDoc) and for most batch documentation systems
  • Energy-saving thanks to permanently heated sealing system and automatic stand-by function to shut off the motor when not in use
  • Also available in high gloss white



The hm 780 DC-V sealing device possess the newly developed hawo htr 780 Process Controller. All functions and settings are provided for the user in this central operating unit.


Integrated Printer

Any normatively required information can be printed directly on the packaging during the sealing process (pictograms as per EN 980). Thanks to the built in FontMatic-technology the printer unit of the hm 780 DC-V automatically adjusts the printout to the film width. Thus, printing past the edge of the film is now history. A maximum of flexibility in the choice of films is guaranteed.



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.



The machines can be equipped with the Hawo ProDoc software for legally secure recording of the welding process.


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.
