Islands, North and Central Africa.
The unique high-tech fiber reinforced           -Hot water is supplied on demand, even in
case production and the long life                the night

and most cost effective solution for
the GCC countries.
The Collector is simply connected to
cold water supply and hot water
return, no additional equipment is
needed.
