The cooling towers in Nigeria’s central bank needed replacing, for which YWCT was asked to design and erect 12 new cells.
The challenge: The towers are situated on the roof of
a 23-story building with no elevator or other means of lifting.
The solution: building a small (2 x 3 meter) service elevator and designing cooling towers to be hoisted onto the roof in modules.
The towers were designed of pultruded fiberglass beams, fully adapted to the roof’s contours.
The towers, heat exchangers, and pumps were lifted onto the roof and assembled in sequence by a local team guided by our project director who was sent from Israel.
The towers, made of materials appropriate to the harsh local climate, are operating successfully.
