The cooling towers shown and described
here are ideal for cooling industrial type
water provided it is chemically and
physically clean.
Usage restrictions
All uses other than those provided for
are prohibited and anyway not advised,
in particular that of water in solutions
with polluting and harmful elements if
released into the atmosphere.
The cooling towers in the TRA series are
used in all cases where it is necessary to
cool water to a temperature near that of
the wet bulb of the outside air.
The use of these devices is particularly
recommended in localities where water
is scarce.
There are seventeen models.
Versions:
• Standard
• Low noise version (L) obtained with
fans with a greater number of blades
and small number of revolutions
•
Two-speed
motor
thermostat.
N.B.:
on towers in the TRA series, it is not
possible to have the option "quiet
functioning" and the option "motor
with double polarity" at the same time.
