Evidence · field history · intellectual property

Evidence presented with context.

We distinguish between documented customer results, historical company records, public patent milestones and estimates derived from external sources. Detailed records are available for due diligence, subject to confidentiality and publication permissions.

Field history

Field-development history

  • 2009

    First field installation and early operational learning.

  • 2014

    Upgraded field installation and further product development.

  • 2019

    A customer letter reported approximately 83% reduction in evaporation losses at one SPPE installation.

Interpretation

How to interpret the 83% result

The figure is a customer-reported result from one installation and operating context. It is not an independent product certification, a universal performance rating or a guarantee for other sites. Expected performance must be assessed and validated for each application.

Further field records, calculations and technical documents can be reviewed with qualified operators, partners and investors under appropriate confidentiality arrangements.

Intellectual property

Recognition
