A residential customer tested Vulcan for 6 weeks. After two weeks, lime deposits noticeably subsided on coffee machine and faucets, and water felt softer. The trial led to a purchase decision.
The Janker family in Berlin tested the Vulcan 5000 alongside two magnetic water treatment devices. Vulcan delivered superior results, installed easily in their old building's tight 25mm clearance, and was ultimately purchased after a trade fair visit. They report immediate softer water and visible scale reduction in their espresso machine and aerators.
Weingut Adam Müller in Leimen, Germany, successfully replaced their salt-based water softener with a Vulcan system at their wine filling station. Operating at 8 m³/h with water hardness of 25-28 °dH and temperatures ranging from 14°C to 90°C, they report no scale deposits—even in the critical warm water and alkaline zones of the cleaning machine.
