Growing a safer, cleaner, healthier future for everyone, everyday.

A goal worth working for.
We look forward to new challenges and an exciting future.

For more than 15 years we have been supporting our customers with solutions for surface, air and water disinfection with UVC. Over the years, the topics and application areas have changed, and even today, our growing experience and continuous product development in the field of UVC technology are opening up new solutions and approaches in more and more areas. The takeover of orca GmbH by the UVGroup of Halma Plc. opens up new possibilities for product development and for the distribution of our successful device series in the world market.

We would be pleased to advise you and develop solution and hygiene concepts together for your special requirements.
