  • 12 months warranty.
  • Maintains equal water pressure in entire system.
  • Withstands pressures as high as 10 to 16 bar
  • Widely used to withstand water hammer in pressurized systems.
  • The VAREM™ tank made of steel never corrodes and no harmful traces of metal are passed into your water.
  • Requires very little/zero maintenance.
  • The tank is made of Food & Drug Administration (FDA) and National Sanitation Federation (NSF) listed materials, thus environmentally safe and will not introduce any undesirable chemicals or elements.
  • The membrane tank is suitable for all kinds of water, even corrosive water with high levels of calcium.
  • The water only comes into contact with the membrane, therefore eliminating the possibility of corrosion.
  • The membrane is easy to replace.
  • Suitable for usage in drinking water systems, which use Reverse Osmosis technology.
  • The membrane which does not rub against tank wall, will have longer life.

VAREM has different range of tanks for different applications such as

  • OSMOVAREM for Reverse Osmosis and filtration systems.
  • SOLARVAREM for solar energy systems.
  • PLUSVAREM for high-pressure systems.
  • INTERVAREM for water booster systems.
  • MAXIVAREM for booster systems.
  • MAXIMATIC-SN for industrial heating systems.
  • FLATVAREM for wall heater systems.
  • PLATEVAREM for plate heat exchangers.
  • ZINCVAREM for zootechnical plants – hostile climatic environments.

VAREM Water Storage Tanks are built tough to last. As a result, they’ve long been known as the world’s most reliable Pressure tanks. Our tanks are individually tested, making them extremely safe. They’re designed to meet the most demanding specifications for potable water. No one offers a broader line of tanks than we do. So, when you’re looking for a Pressure tank for a specific application, you can be sure we’ll have it for you.

The bladders for pressure tanks are made of a compound for products intended for con-tact with drinking water or for water to be conditioned. The white-cream coloured com-pound is made up of a mixture of NATURAL RUBBER, natural mineral fillers, mineral white oil refined for pharmaceutical use, physiologically harmless pigments and non-toxic vulcanizers. The maximum working tem-peratureis 60°C. By request, we can supply black bladders in EPDM – synthetic rubber – (ethylen/poly-propylene) resistant untill a temperature of 90°C and in BUTYL – butyl synthetic rubber, whose resistance reaches 100°C. Hardness: 40 ±5 SH
