Isolation of TAGs

The project already has three tanks of cold water (TAG)
mounted with approximately 300,000 liters of water each.

To reach this point, water-tightness tests were performed
according to the Inspection and Testing Plan (PIT in
Portuguese) elaborated for the project, and in compliance
with the Brazilian Standards regulations. Furthermore, each
tank was checked by visual inspection and topographical
monitoring, being issued an accordance report for each 20% of
the filling of each tank.

The tests showed the solidity and the tightness of the tanks,
which are consistent with the design specifications. These,
of course, the result of a strict quality control, we had talked
about in the previous posts.

The next step was to start the thermal insulation of it. The
thermal insulation is a key point when it comes to the energy
efficiency of the air conditioning system, and also to prevent
condensation outside.

The engineering work had to find at an optimized point,
between cost and benefit of the material to be used,
considering the optimal density of the material, and the
thickness required to prevent the heat transference through
the walls of pipes and tanks. This is also the result of an
extensive study of laboratory and field tests.

Is valid to remember that, after isolation, the pillars will be
built of reinforced concrete around each tank, which will later
be coated also with stones from Israel.

Therefore, the insulation will be enclosed and its
implementation should be done flawlessly and definitive.
