| Different Tanks for Different Needs | ||
|---|---|---|
| One size and style does not fit all. At Sekisui we have consistently listened and responded to the demands of our customers who desire special products for special situations. | ||
 | ||
| F-Panel Tanks | ||
Sekisui tanks using GRP panels are Sekisui's most important product. There are various types which differ according to the type of resin used.
GRP stands for Glassfibre Reinforced Polyester and is also sometimes referred to as FRP. The use of glassfibre for reinforcement results in a strong product which excels in resiliency. Of the polyester resins used for GRP panels, there is a standard type and a heat-resistant type. Selection between the two is made according to the required application. |
|
|---|
| Resin Type | Applicable Tanks | Features of Resin |
| Standard resin | Cold water tanks (section tanks, roof tanks, fire-fighting tanks, etc.) | |
| Heat-resistant resin | Hot water tanks (hot-water storage tanks, hot-spring storage, etc.) | Heat-resistant temperature: 80°C |
| Insulated Tanks |
|---|
Our insulted tanks are constructed of GRP injected with foamed urethane and are superior in their heat and cold insulation.
Appropriate for tank insulation in locations such as machinery rooms, rooms with high humidity or areas of cold climates.
|
| ThermaStore Tank |
|---|
ThermaStore tanks offer a hot water supply system - with excellent heat insulation and minimum heat loss - that can withstand a maximum temperature of 80°C. By installing a heater, heat exchange or other system inside the tank, the amount of energy available can be used more efficiently.
Due to the excellent heat resistance of the panel material, this system shows remarkable endurance. Applications: Hot-water storage, Heat storage, Storage for air-conditioning purposes, Hot-spring storage |

| Other Types of Tank |
|---|
| EconoTank | ||
|---|---|---|
Based on Sekisui's GRP Panel Tank System, the EconoTank is perfect for all small capacity water storage systems. It has two major advantages: simple assembly and disassembly, and - as its name implies - the Econotank is easy on your budget.
It is also quite mobile. A one-ton capacity tank fits easily into the rear of a station wagon, and weighs less than 50 kg (110 lbs). |
| Earthquake-Resistant Tanks |
|---|
 | ||
| Superior design proven safe for superior earthquake resistance | ||
|---|---|---|
| The most important point of a tank's design for earthquake resistance is the ability of its rigid construction to survive the specific oscillation frequency of the seismic waves (the oscillation frequency of the strongest wave of an earthquake). Through an abundance of practical test data, Sekisui also offers an earthquake-resistant panel tank which utilises our proprietary "box frame" construction (externally reinforced) for excellent stability and high rigidity. | ||
| Using this wealth of data and accompanying computer analysis, Sekisui is able to offer the utmost precision in design of the most highly reliable panel tank on the market today. And it is through this care in design that we are able to offer an earthquake resistance which can handle a horizontal seismic intensity of 0.3 - 2.0G, easily responding to a variety of customer needs. |
| Proven data from earthquake simulation testing | ||
|---|---|---|
| Tests have proven that Sekisui tanks can withstand an earthquake's specific oscillation frequency and protect against resonance when the height of the tank installation is above 10 meters. |

| How Sekisui tanks withstood disaster | |
|---|---|
 |
During the Great Hanshin Earthquake of 1995, water and electrical lines were destroyed and people were no longer able to carry on with their normal everyday lives. Throughout the chaos and disorder, Sekisui panel tanks withstood the 7.2 magnitude earthquake and protected and preserved the water they were holding. These reserves were able to supply water to those in need, helping ensure their survival.
After the earthquake, Sekisui performed earthquake testing on its F-panel tanks. Subsequently, Japan - often referred to as the "Country of Earthquakes" - adopted the data determined during these tests as the new standard for earthquake-resistant water supply equipment. |
