The factory had been operating for more than a year without any water treatment and the built-up mineral scale impacted cooling efficiencies, and reduced water flow and pressure.
To solve the limescale problem of the central air conditioning system by using the eco-friendly Vulcan technology without salt or chemicals.
The China Academy of Railway Science (CARS), founded in 1950, installed a Vulcan 5000 on the domestic hot water supply of their staff cafeteria to solve scaling of water heaters, faucets and shower heads.
Junlebao Dairy Group, one of China's leading dairy producers, installed Vulcan descalers across three facilities in Hebei province. With 7 units deployed—including S25, S150, S250, S350, and S500 models—they protect critical cooling water circulation, chilled water systems, and reverse osmosis water reuse lines from mineral scale.
Tangshan Kailuan Group Linxi Mining installed a Vulcan S350 in an explosion-proof box 600 meters underground to solve scaling and corrosion in their drainage system.
Chuishan Hot Spring Resort in China installed a Vulcan S100 on their hot spring pipe system. After 6 months, scale significantly reduced, eliminating need for manual cleaning.
A heat exchange station serving the Century Jiayuan community in Hebei, China, replaced its traditional water softener with a Vulcan S100. The non-chemical solution prevents fouling of the critical plate heat exchanger, ensuring efficient heating for residents while eliminating salt and maintenance costs.
Two Zhaolin Plaza office buildings in Beijing's core business district installed Vulcan S500 units on their central air-conditioning circulating water systems. After 5 months, chemical inhibitors were completely replaced, scale fell off cooling tower packing, and the system operated stably with conductivity up to 6630 µS/cm—significantly reducing wastewater discharge.
Dongfeng Honda Automobile Co., Ltd. in China installed a Vulcan S25 on production robot cooling lines. After 3 months: scale significantly reduced, chemical use decreased, $4,700 annual savings.
The Starcastle Xiangshan Nursing Home in Beijing, sourcing water from underground wells, faced severe scaling that required frequent acid cleaning of heat exchangers and caused pump failures. After installing a Vulcan S25 on the main heat pump pipe, 9 months of operation showed eliminated scaling, no pump burnout, and dramatically reduced maintenance costs—without chemicals.
