Q
The exclusive Marley System5
Geareducer
®
requires no oil changes for
five years, offering you unmatched reli-
ability and low maintenance.
Q
For many years, a feature of Marley-designed cooling towers was
that the electric motors were located outside the fan cylinders,
where they were easily accessible, and where they were not
subjected to the constant humidity that exists inside the tower
plenum.
Although improved motor designs (insulation, bearings, seals,
and lubricants) have now made it feasible for us to locate the
motor inside in close-coupled proximity to the Geareducer, many
users still prefer the motor to be located outside the humid air-
stream. If you are among those users—or are among those who
see the wisdom of their thinking—please specify this option.
Q
For process fluid above 135°F (57°C).
Q
In wooded or windy areas, these screens help to keep leaves or
blowing debris out of the cooling tower and circulating water
system.
