Cooling tower infill is one of the most important components for
exchange of gas and water in cooling tower.
It is the major parts to improve the efficiency of cooling tower
and make sure the economy and safe operation. With the development
of the plastic industry,countercurrent tower drench water plastic
packing "S" shape ladder wave, inclined corrugated fills, which has
the heat dissipation, durable, good performance, ventilated small.
resistance, based on the easy and other advantages. It is widely
used in different types of large, medium, small, cooling tower.
With cooling towers, fill selection is a critical aspect in this regard. High efficiency film fill may seem the most desirable option. However, if poor water quality causes this fill to rapidly foul and plug, it may incur excessive maintenance costs.
Most cooling towers now utilize film fill to enhance air/water
contact. Film fill, as the name implies, induces the cooling water
to form a film on the material surface. The filming mechanism
maximizes liquid surface area. A guiding principle behind fill
design and selection “is to increase air-to-water contact, driving
up convection and evaporative cooling while reducing pressure drop
in the system”
CF750mm cross fluted fills typically provide high specific surface
area and high thermal performance but exhibit poor anti-fouling
characteristics due to the geometry that forces many deviations to
the flow path.
Flute spacing significantly affects fill performance; smaller
spacing increases the surface area but also raises the
potentialseverity of fouling

The fill is the most important part of the cooling tower, and its
efficiency depends on the degree of sufficient contact between the
cooling water and the air in the fill. The company's packing is
temperature resistant* 1. It is easy to install, easy to clean, and
easy to transport. The heat dissipation packing adopts a
non-adhesive suspension type, which is easy to install and easy to
clean, and successfully solves the problem of the deformation of
the adhesive packing due to dust accumulation and self-weight. ,
and the fouling after deformation is more serious and difficult to
clean. The filler has good flame retardant performance. After
testing, the flame retardant oxygen index index is greater than 28.
* 2. The large "honeycomb" structure design has a diversion effect,
which has a good uniform air distribution effect, improves and
stabilizes the heat exchange intensity of water and gas, and the
wind inlet end is inclined at an angle of 30 degrees, which
effectively reduces the drift loss. The precise positioning and
equal spacing combination is convenient to form a large-area
flowing water film with the water flow perpendicular to the
surface, which promotes the contact surface of the atmospheric air.
, The unique and high-efficiency water eliminator is integrated
with the packing, which effectively removes the water droplets in
the hot and humid air and returns to the tower, which greatly
reduces the loss of drifting water. The floating water loss rate is
less than 0.001%.
1. Manual cleaning of the slag falling off in the cooling tower;
2. Rinse the packing repeatedly with a high-pressure water gun to
remove the sludge and scale under cleaning;
3. Dissolve the TNB descaling agent with hot water at about 50°C,
and then use the flushing pump to rinse the filler repeatedly until
the scale is rinsed off (if the filler has a long service life,
causing aging and collapse, it is recommended to replace the
filler), and add algaecide at the same time. Completely kill
biological algae and;
4. After confirming that all parts of the system are cleaned, drain
the sewage;
5. Rinse the packing and the inside and outside of the tower body
with clean water;
6. Restore all parts of the system, replenish water and use it;
7. After all recovery, please check and accept the management
personnel of Party A;
8. Evacuate Party B's belongings and clean the site;
