Our service includes:

    The tubes are looped and cleaned with hot water (60 °C, OPPTIMAL/WATER 1:5), rinsed with clean water and dried with nitrogen or breathing air. The inside is then analysed with the CCI4 test to ensure that no extractables or hydrocarbons exceed limit values.

  • Documented maintenance
    All cleaning is digitally documented with history and reminders, providing full control and traceability.

  • Third party inspection and accredited analysis
    We offer independent inspection and purity analysis using IR technology, including control of aromatic and aliphatic hydrocarbons.

  • Flexibility and manufacturer service
    We work with all brands and ensure that the manufacturer's requirements are met. Our solution is scalable and customisable to your needs.

  • Focus on safety
    We comply with the Swedish Work Environment Authority's regulations and help you prepare for regulatory inspections.
