ServiSeal
For all hawo sealing devices we or our qualified global service partners offer ServiSeal, a professional maintenance service. During ServiSeal, the sealing systems are cleaned, worn parts are replaced and then the functionality is tested. Sealing devices whose processes have been validated should be recalibrated before each revalidation.

CaliSeal
With CaliSeal we offer a comprehensive calibration service for correctly setting all the relevant variables (e.g. sealing temperature). The permissible tolerances determined during calibration are documented in a calibration certificate. hawo sealing devices with ‘V’ are supplied calibrated. The sealing process can thus be validated directly. Also for annual revalidation, calibration (CaliSeal) should be carried out before validation.

ValiSeal
With ValiSeal, our certified validation team carries out the initial validation (IQ, OQ and PQ) directly on site (e.g. in the CSSD/RUMED) in accordance with EN ISO 11607-2 / ISO/TS 16775. Afterwards, our customers receive full validation documentation (validation report).
If the packaging process has already been validated, an annual revalidation is usually sufficient. In most cases, this only consists of a new performance qualification (PQ), i.e. a new seal strength determination, which is documented in the validation report.
A prerequisite for validation is that the sealing devices comply with the EN ISO 11607-2 standard and the new ISO/TS 16775 guideline.
