Our former
Marley 495B galvanized cooling tower became severely corroded and
scaled, due to a lack of cooling water treatment. Additionally, the steel
support structure was badly corroded.
To fit into the rectangular
concrete well originally occupied in 1952 by a redwood slat tower, two circular
50-ton fiberglass towers
were bought from
CTS in Georgia.
The old cooling tower
and structure were cut up and dumped, and a new treated timber column support
structure plus
full walkway were installed.
A tall aluminum gantry was then built to
chain-hoist these towers in place, finally plumbing & electricity reconnected.
See drawings and
photos of the
month-long project.
Using paid day labor plus volunteers, the summer 2009 project came in right at
the $17,500 donated by our congregation
members. The commercial HVAC
contractor who will now do quarterly
inspection and maintenance of our central HVAC is
Polar Air. Treatment specialists
Aquatrol have installed digitally controlled water treatment which
they will monitor monthly to control scaling, corrosion
and biological growth. Bob
