About Hotel Isla Mallorca & Spa
Hotel Isla Mallorca & Spa is a prominent hotel located in Palma de Mallorca, in the heart of the Balearic Islands, Spain. With 163 guest rooms, a restaurant, bar, and beautiful garden areas, the hotel caters to both leisure and business travelers seeking comfort and luxury.
In the hospitality industry, consistent water quality is essential—from guest bathrooms and kitchen operations to spa facilities and landscape irrigation. Limescale can quickly lead to clogged showerheads, inefficient water heaters, spotted glassware, and increased maintenance costs. The hotel's management took a proactive approach by installing a comprehensive Vulcan system in June 2022 to protect every water-dependent aspect of their operation.

The Challenge: Protecting Every Water System in a Large Hotel
A hotel of this size has diverse water systems, each with unique scale prevention needs:
- Hot Water Circuit: Large diameter pipes (110 mm) serving guest rooms and kitchen required protection to maintain heating efficiency.
- Main Cold Water Lines: Separate supplies to Building 1 and Building 2 needed treatment to prevent scale in all downstream fixtures.
- Water Deposit Line: The main storage tank supply required protection to ensure stored water remained scale-free.
- Irrigation System: Garden watering lines needed protection to prevent clogged sprinklers and ensure healthy landscaping.
