"Krystall units are particularly well-suited to address the extreme and
chronic clean-water shortages of countries like Algeria" said SwissINSO
VP Paul de Belay. "We're very pleased with the decision to choose our
technology. This agreement also represents an important opportunity for the
growth of our business in the North Africa region", he added.

Working in conjunction with a local partner and distributor,
the unit is expected tobe fully-functional by early April 2011 and will serve
as a showcase for other regions in Algeria and neighboring countries.

Krystall is the world's first high-volume fully solar-powered turnkey
water purification system housed within two standard 40-ft (12.2m)
containers. Its patented reverse-osmosis technology can purify up to 100,000
litres per day of brackish/contaminated water or 50,000 liters of seawater
into pure drinking water. Operating and maintenance costs are a fraction of
conventional units.

Krystall is perfectly suited for servicing remote towns and villages,
humanitarian and relief situations, hotels, islands and turnkey camps.

A video description of the Krystall water purification system can be

assembly is demonstrated in a virtual tour at
