Vulcan Models installed:
2 x Vulcan S25 units were installed in the inlet and outlet pipes of the cooling tower to solve the scaling problem of the chiller in the power room No. 3.
3 x Vulcan S50 units were installed in the inlet and outlet pipes of the cooling tower to solve the scaling problem of the chiller in the power room No. 1.
2 x Vulcan S250 units were installed in the inlet and outlet pipes of the cooling tower to solve the scaling problem of the chiller in the power room No. 2.
All Vulcan units treat the centrifugal chillers The central air-conditioning cooling water system was heavily scaled and difficult to clean. The customer is looking for an environmentally friendly way to replace traditional chemicals. Before there were automatic dosing machine that added a little bit of chemical every day, but now Vulcan replaces the use of chemicals.
The effectiveness of the physical water treatment has not only been proven by users but that there are also theoretical and practical physical-chemical proofs. View PDF here →

Paper 1: The present study investigated the feasibility of RF electrical fields in mitigating CaCO3 fouling in cooling water. Three different voltages and two frequencies were used for the RF electric fields produced directly in water with varying cold-side velocity. Artificial hard water was used. Fouling resistances for the PWT- treated cases decreased by 34–88% from the values for no-treatment cases . View PDF here →

Paper 3: Electrodialysis in the presence of humate. It was reported that the application of external electric fields with pulsation and infrasonic pulsing could give substantial improvements in the performance of pressure-driven membrane processes by reduction of concentration polarization, control of membrane fouling .

Paper 4: Induction of a Radio-Frequency Alternating Electric Field (RFAEF) in water at a specific range of frequency and antenna voltage, along with its distinct sinewave waveform, changes the way minerals precipitate, minimizing hard-lime scale by producing instead a non-adherent mineral powder in the bulk water. Moreover, the unsaturated solution that is created, along with enhanced carbon dioxide production, dissolves gradually the existing scale in plumbing tubes. Furthermore, the RFAEF inductance device demon- strates a major improvement over other pulsed-power systems, proving this electronic antifouling technique suitable for both hard and soft waters, as well as for large-scale applications.
