1
Vulcan S50 Unit
Location: Havblik, Køge, Denmark
Installation: Vulcan S50 on the main water line for the entire piping system
Protected Systems: All pipes, pumps, and water tanks in the basement serving 66 apartments
The Challenge
The condominium was dealing with limescale buildup in pipes and water heaters across 66 apartments. They needed to solve the problem without relying on manual cleaning ("elbow grease") or chemical treatments. Traditional water softeners were considered but rejected due to high operational costs, negative environmental impact, and effects on water quality.
The Solution: Environmentally Friendly Scale Prevention
Main Water Line
Installation: 1 x Vulcan S50 on the main water line
The condominium chose Vulcan over traditional water softeners because it eliminates:
- High operational costs (no salt, no maintenance)
- Negative environmental impact (no chemicals, no discharge)
- Effects on water quality (water chemistry unchanged)
Vulcan Model Used
This condominium installed the Vulcan S50, ideal for multi-family buildings with pipe diameters up to 5 inches and flow rates up to 300 GPM.
