Technique principle
DPC Non-Electric atomization cooling tower, take full use of the press existed in the circulating
water system. the press water goes into the " fog Spray rotating device" on the bottom of the tower
through the inlet pipe and turned to be the spray fog sprayed from the nozzle, under the push force
by the fog spray the nozzle and the blade are rotated at the same time, by which rotation force, the
central fugal is generated to increase the pressure of the flow centrifugal, and the spray flow is
even faster. In turn, it also accelerates the atomization and increased the speed of atomization
rotation, finally conversion the most of the energy of the water into the wind energy, enable the
hot water fog flow and the cold air to be fully exchanged, and then the purpose of dropping
temperature by the circulating water is reached.

Technical characteristic
The design feature of the DPC Non-Electric atomization cooling tower
makes it even more stable and desired and has better effect of cooling
results than traditional cooling tower.
1 the water can be dispersed into the fine corn into the fog shape
through the dispersal device , which can make the cold air and the
particulate of the water be evenly contact, which largely increase the
exchange area and efficiency of exchange.
2, there are three processes for the water in the cooling water, including:
upward, suspension, and decrease. While there are both down stream
cooling and counter flow cooling, enable it to contact even longer with
dry and cold air, and take away more heat.
3 the isolation of the water spraying board and the body of tower, avoid
the return air and the several of the atomization device mutual
interfering, and at same time, the fog flow can make the second time
ejector air. The mutual of the superimposed on mechanical ventilation
and the ejector air, increase the gas-water ratio.
4, the reasonable configured air channel and the water spraying device , features of the air
resistance small , the reasonable wind farm, and low partial pressure of steam.

1.100% power saving. No electric drive. ：
2．Low cost of normal daily maintenance: free cost of maintenance the motor, and free expense on
large amount of packing exchange.
3. Good result of cooling effect and stable of the maintenance e of temperature drop: the water
within the tower is exchanged with the inlet air on the fog condition; there is no blog of the
packing and damage of motor, the stable of drop temperature.
4 small water-drift rate, the excellent performance of water collection device on the top of the
tower, can save the 20% water than the packing cooling water tower.
5. The mute design ensures the low noise: the equipment is especially applicable for hotels,
restaurants, hospitals, schools and surrounding neighborhoods, without the motor, so free of the
noise of rotating machinery and equipment.
6. the safety operation can be ensured: Without the motor so the electric fire during the operation
can be avoid, neither the shut down accident caused by the blow happened.
7. there is no attenuation cooling problems: a large amount of packing is eliminated, so the
disadvantages of the attenuation caused by the large amount of the packing after fouling and
iching can be overcome.
8. simple maintenance: complete elimination the trouble of frequent cleaning, replacement of
packing, and distribution water nozzle.
9. Reliable operations: due to eliminating the motor, the distribution cabinet distribution cabinet,
and the control cabinet etc which controlled the motor fan, to exclude the various factors that
affect the stable operation.

10 no special requirements on water pressure: it can apply the renovation on almost all traditional
cooling towers, which can be better reflect the technical advantages for the project which taken the
pumping water system energy saving.
11 No special requirements on water quality: the diameter of atomizing nozzle is greater than 12,
not easy to be clogging, , and large velocities of the nozzle flow make the fouling hardly to be
shaped.
2 the adjustable amount of cooling water: for the given model of the cooling tower, can increase
the water supply pressure and change the nozzle aperture to adjust the amount of water and
temperature drop.
13. The light body, flexible combination: reduced the requirements for the base, variety of the
combination of the units, enable it to be flexible combined according to the sites, for the required
more amount of cooling water , better reflects the advantage of the techniques.

Example illustrates
Take a steel plant as an example, in 2008, the cooling tower of the steel plant was renovated as the
Non-Electric type of cooling tower. For example , a cooling tower of 1200 m3 / h, which with the
electricity charged 0.55 Yuan/Kw, 24 hours a day and 330 days/year, the annual electricity savings
by using MDPEG series of the Non-Electric atomization cooling tower as: 45KWX24 hours
X330 days X0.55 Yuan / kWh X1 =196,020 Yuan, in which the fan motor is replaced. It saved the
costs( total power consumption 6%) by motor repairing and maintenance is: 196020 x 0.06 =
11761 Yuan; after the renovation the total saving cost of the year approximately : 196020
+11761 = 207,781 Yuan; reducing loss of the water-drift after renovation :1200013x1 X330 - day
X24 hours X 0.002 X 3.8 Yuan / ton = 72,230 Yuan ; save packing cost annually about 5,000
Yuan . total saving cost of the year approximately : 207781 + 72230+ 5000 = 207,781 Yuan after
the renovation. he investment in equipment can be returned with one year, which shows the
considerable economic and environmental benefits .
