Vulcan descaler systems were selected to address the limescale problems encountered throughout the manufacturing plant.

Delphi Technologies installed Vulcan Commercial Descalers for environmental protection and energy saving; and to replace existing scale and corrosion inhibitors. Delphi Technologies provides combustion systems, electrification products and software and controls, and operates in the passenger car and commercial vehicle markets, and in-vehicle repair through a global aftermarket network. It is headquartered in London, U.K. and operates technical centres, manufacturing sites and customer support services in 24 countries.

Vulcan descaler test in Large Industry We decided to conduct a test in the factory TopTex Maroc to convince the customer to the result of the Vulcan Anti-Scale system.The objective was to see the change on the old limescale in the chosen pipe. The factory uses two...

Yili City heating stations installed:
3 x Vulcan S50
23 x Vulcan S100
3 x Vulcan S150
35 x Vulcan S250
5 x Vulcan S350
6 x Vulcan S500
The heat exchangers were cleaned before installing Vulcan. The customer gave Vulcan positive feedback that the cleaning interval of the heat exchangers has been extended and the workload has been greatly reduced.

Vulcan descaler for the Be’er Sheva Grand Mall

The Be’er Sheva Grand Mall is the largest shopping mall in the southern region of Israel, located in Be’er Sheva – the capital of the Negev. It features 220 stores.

The Vulcan S250 was installed on the roof. The temperature at this time was 38 – 40 °C. In winter, it is rainy and the wrap should be sealed to IP-68. Vulcan impulse bands were well wrapped and the Vulcan unit was in the outdoor water proof box.

Each cooling tower has 2 heat exchangers.
The difference in pressure increased between the inlet and outlet of the heat exchanger, which showed a developing blockage. The heat exchangers had lost in work capacity every month due to the multiplicity of scale and rust.
5 months after installation, there are no scale issues in any cooling tower heat exchanger systems.
Due to the excellent results, more Vulcan will be installed for the rest of the company’s facilities in Israel.
The differences are clear:
 – The pressure difference is lower between the exit and the inlet of the heat exchanger in the right tower.
 – The water coming out of the heat exchanger is colder in the right tower.
Since Vulcan descalers were installed, the regular chemical cleaning process has been stopped.

Due to the successful installation, performance and results of the Vulcan Descaler systems will now be installed at other sites that the group manages and operates.

Vulcan S150 was installed in the heating system in the low zone of the heat exchange station (below 6 floors);
Vulcan S350 was installed in the heating system in the high zone of the heat exchange station (above 6 floors).
To solve the scaling problem of the plate heat exchanger, to prolong the cleaning time and to improve the heat exchange efficiency.

Jizhong Energy Group is based on “central heating” as its main business and integrates energy to develop centralized heating industries. Jizhong District Heating Company, as its subsidiary company, founded in 2010, provides safe and stable heating.

The water source is groundwater, and the plate heat exchanger was scaled badly. A 4 months trial was conducted with Vulcan systems (November to March). The customer stopped using any additional chemicals to treat the water. After installing Vulcan anti-limescale systems for 4 months, the effect was very clear.

1 x S500 installed in the heat exchange station (The primary water temperature of the equipment is
65 °C, the secondary water temperature is 45 °C)
1 x S250 installed in domestic hot water system (The primary water temperature of the equipment is 80 °C, the secondary water temperature is 60 °C)
The water is underground well water. Vulcan S500 was installed after cleaning the plate heat exchanger. After 4 months, no white scale was seen, only yellow rust was left. Although there were still substances in the plate heat exchanger, they had been softened.

Although there were still substances in the plate heat exchanger, they had been softened and could be easily removed by hands. There are no more white scales, only yellow-brown impurities left.

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.

Mitac Couputer manufacturing installed:
1 x Vulcan S500
7 x Vulcan S250
2 x Vulcan S50
4 x Vulcan S25
10 x Vulcan S10
to help remove existing limescale from pipes and equipment, improve manageability, sustainability and profitability in many areas. Vulcan protects against rust and corrosion for water-fed appliances to reach their maximum life expectancy and keeps their maintenance to a minimum. Leading to lower running costs, better heat transfer and heat recovery operations.
