· Commercial line targets hotels, catering, and hospitals: Modular central water purification packages (daily water supply of 5-50 tons), catering-specific equipment (NSF certified, food-grade materials), hospital-specific models (UV disinfection, 99.999% bacteria removal rate).
· Industrial line focuses on chemical, power, and pharmaceutical industries: Circulating water treatment systems (intelligent integrated chemical feeding and filtration), pharmaceutical purified water equipment (conductivity < 1μS/cm), industrial fluid control valves (precision flow regulation, adapting to complex working conditions).
It holds a 10.2% market share in North American water treatment (ranking first in the industry), 18% in commercial RO equipment, 12% in industrial valves, and 7% in household whole-house packages. Globally, it ranks among the top three together with Veolia and Xylem, accounting for 12% of the market share.
The user satisfaction rate in North America is 91%, and the repurchase rate among commercial users exceeds 90%. Its core advantages are low equipment failure rate (annual failure rate < 2%), 24-hour on-site after-sales service, and timely supply of accessories. Household users recognize its filtration effects and intelligent functions, but the entry-level RO machine is priced at $1,200 - $1,500, and the whole-house package at $4,000 - $6,000, with a relatively high premium.
There is never a "best brand," only the "most suitable choice."
