Vulcan descaler for Acacia Hotel – Davao
Acacia Hotel Davao provides 260 guest rooms and 9 spacious event spaces.
Our company was very pleased with the Vulcan results installed on our main condenser line and main hot water line in Acacia Hotel Manila.
Although there were a few conflicts that happened last May, the problems have been solved gradually until November when the approach temperature was back to normal at 3-6 °C due to the instructions you have given and a few more regular cleanings.
Also, this year’s summer season in the Philippines, the temperature reached its hottest record at 37 °C here in Manila, however, due to the improved and cleaned A/C system, we haven’t got any problem with it.
With those positive results, our head office has decided to install another unit in our next hotel, located at Davao City. The A/C system design was the same as ours, with 16-inch pipe.
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.
