Equipment for the desalination of seawater, comprising a heating tunnel with a transparent wall and a convexly transversely curved top which form a closed circuit and house a set of longitudinal tubes which are open at their ends and close to the top of the tunnel, a series of trays containing seawater, a condenser and a fan. The action of sunlight causes the tubes and the air within it driven by the fans to be heated, and this is then directed over the water in the trays, and finally passes through the condenser. <IMAGE>
