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.

Nippon Glass installed Vulcan anti-scale systems:
1 x Vulcan S25
2 x Vulcan S500
to help reduce the damaging effects of limescale and reduce maintenance costs

Why did Korea Water Services install Vulcan descaler systems?

The Korea Water Resources Corporation, or K-water, was is the governmental agency for comprehensive water resource development and providing both public and industrial water in South Korea.

K-water has been in contact with commercial and industrial customers such as Hyundai, Toray and others reporting positive results after installing the Vulcan anti-scale systems.

The performance and associated benefits of notable success prompted K-water to install the Vulcan anti-scale solution.

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.

The 5-star Barceló Bávaro Palace hotel is one of the top luxury hotels in Punta Cana, and has selected the Vulcan anti-limescale systems to save money on cleaning, repairs and renewals. Additional savings of up to 30% were made on heating and cooling systems.

Benefits from Vulcan S500:
– Reduced chemical dosing and chemical costs. The dosing of scale inhibitor chemical was reduced from the initial 6 liters per day to 1 liter per day.
– Reduced scale formation.
– Loose and easily removable scale on cooling tower fills. Man power is reduced due to easy maintainability.
– Reduced AMC (annual maintenance contract) cost.

Enco Energy Complex uses the
3 x Vulcan X-Pro 1
1 x Vulcan X-Pro 2
Anti-limescale systems and is the first office complex in Thailand and Southeast Asia to be awarded the highest level of Platinum Green Building certification. Vulcan was added together with the ozone system to treat the water. After 4 months, the approach temperature of the chiller has been reduced, so that the energy has been saved from the machine. Also, the limescale from the cooling tower basin have been reduced.

1. Cooling tower and chiller system: after Vulcan S500 has been installed for 1 year, the condenser approach temperature < 2°.

2. Cooling tower: after installing Vulcan, we still keep the chemical dosing system and check the water monthly. We reduce chemicals every month. After6 months withVulcan, the chemicals have been greatly reduced more than 80%.

3. Process water pipes: no need to clean every 3months. The client has never cleaned by far withVulcan.
