The historic Furama Hotel Dalian, a 30-storey, 620-room luxury hotel in northeast China, installed a Vulcan S25 on the hot water heat exchanger inlet. After 10 months, hard scale was removed from heat exchanger fins, shower heads stayed clean, and rusty water issues on floors 12-25 were eliminated—saving energy and maintenance costs.
Furama Hotel Dalian is a luxurious five-star hotel with a long history in northeast China. This landmark 30-storey building houses a total of 620 guest rooms, making it one of the largest and most prestigious hotels in the region.
With such a large operation, maintaining consistent water quality across all floors is a significant challenge. Guests expect clean, clear hot water for bathing, spotless bathroom fixtures, and reliable comfort. The hotel was experiencing persistent problems: rusty water from hot water pipes, unsightly scale buildup on shower heads, and scaling on critical heat exchanger fins—all affecting guest satisfaction and operational efficiency, particularly on floors 12 through 25.

The hotel faced a combination of serious water quality issues affecting guest experience and equipment efficiency:
Rusty Bath Water: Guests on floors 12-25 complained of discolored, rusty water from hot water pipes.
Shower Head Scale: A thick layer of scale would build up on shower head surfaces, giving them a dirty, neglected appearance.
Heat Exchanger Fouling: Hard scale between the fins of the heat exchanger was affecting heat transfer efficiency.
Blocked Outlets: Scale buildup was clogging shower head nozzles, reducing water flow and pressure.
The solution needed to address both existing scale and ongoing prevention, while being safe for a hotel environment and capable of treating water for 14 floors from a single installation point.

BEFORE
The hard scale between the fins affected heat transfer efficiency and rusting caused rusty water problems.
AFTER 10 MONTHS
The fins were not cleaned before installing the Vulcan S25. 10 months later, the hard scale was removed and some areas revealed the original copper colour.
Vulcan has improved water quality and saved energy and manual cleaning costs.
