A condominium in the Grindelwald Mountains, Switzerland installed a Vulcan S100 in their sanitary facilities. PH testing confirmed perfect functioning with a measurable reduction of 0.15–0.12.
Nestled in the stunning Grindelwald Mountains of Switzerland, this condominium sought to protect its sanitary facilities from limescale buildup using advanced, verifiable technology.
The property installed a Vulcan S100 anti-scale system and used scientific PH measurement to confirm its effectiveness—providing concrete proof of performance rather than just observational results.

Measurable PH reduction verified

Property: Condominium Crassier
Location: Grindelwald Mountains, Switzerland
System: Vulcan S100 in sanitary facilities
Verification: PH measurement before/after
When Vulcan treats water, the change in lime crystallization consumes less CO₂, which slightly but measurably lowers the PH value.
Measured reduction: 0.15–0.12
"The reduction of 0.15–0.12 is a result of the good functioning."

The Science of PH Testing
When Vulcan treats water, the change in lime crystallization consumes less CO₂. This release reduces the PH value slightly but measurably.
Measured reduction: 0.15–0.12
"The reduction of 0.15–0.12 is a result of the good functioning."
This scientific verification confirms that the system is actively converting lime and protecting the sanitary facilities.
The Condominium Crassier case study provides unique scientific verification of Vulcan's effectiveness. The measurable PH reduction of 0.15–0.12 confirms the system is actively converting lime and protecting the sanitary facilities.
