Providing water in dry places

Hot-pressed panels are becoming one of the best ways to construct a sturdy and leak-proof GRP cistern for storing water. Not only are they remarkably durable, but they are also designed to withstand a pressure that is higher than their intended working pressure.

The Middle East has some of the lowest levels of rainfall in the world, making the availability and storage of potable water enormously important. In this region, cisterns need to be designed to be used effectively in nearly every geographical setting and climate, whether it be urban, rural, coastal, or desert terrain.



Dubai-based Thermoset Technologies Middle East (TTME) is supplying this demand with hot-pressed panel tanks in glass-reinforced plastic (GRP). TTME Technical Director T. K, Chakraborty pointed out that, while the tanks are popular in the Middle East, the company is also seeing good sales from England, Japan and the Far East.


Building the cisterns


According to TTME, the panels it uses for the tanks are some of the best in the business. Much of that is due to the hot-press moulding process, which offers better precision and finish.


In the process, the panels are formed from hot-pressed, glass-fibre-reinforced polyester that is produced using Sheet Moulding Compound (SMC) material. The panels are moulded at temperatures as high as 150°C, and under high moulding pressure. The outcome is that tanks of nearly any shape or size can be built with optimum results. All tanks offer integral insulation and can be used in a large number of home and factory applications.




Thermoset Technologies Middle East specialises in the manufacturing of hot-pressed GRP panel tanks, producing exceptionally safe and long-lasting storage tanks for drinking water. Today, it is trying to expand its product horizon with ten new projects, which are in various stages of development. The company was established through M’Sharie LLC, a subsidiary owned by Dubai Investments PJSC.


In an interview Mr Chakraborty told us: “The most frequent use of this product is for storage of potable water in small, medium and large multi-storied buildings, schools, hospitals and large office complexes.”



Advantages abound


Using chemically resistant isophthalic polyester resin systems gives these panels and tanks a number of advantages, including better water, bacterial and osmosis resistance.


But TTME says the advantages hardly end there. It claims that the tanks also require less maintenance and lower installation costs, as it is simple to assemble and dismantle. Furthermore, the tanks are designed to be used in climates of extremely hot and cold temperatures for more than 50 years. This is particularly useful in the Middle East, where the temperatures between night and day can fluctuate enormously.
