Crossflow Industrial Water Cooling Towers Automatic Temperature
Control
COOLING TOWERS:
1) Closed loop
Preventing the impurities into the system to block the cooling
tubes, soft water is adopted to avoid overheating caused by scaling
to the water pipes.
2) Automatic temperature control
Automatic start/stop spraying system to achieve effective control
on the temperature of cycled cooling water, the temperature of the
cooling water can be controlled below 40 ℃. With this function, the
water & energy cost is reduced to the lowest point with intelligent
control to the number of working fans and start & stop of spray
pump.
3) No need of water pool and cooling tower
Low cost, small space occupancy, easy installation and move with
the welder.
4) Automatic digital display of temperature control
Energy efficient and user friendly.
WORKING PRINCIPLE
1, Working fluid (water, oil o other liquid) flowing inside of the
coils, which is enwrapped by spray water on the outside. The heat
of water is transferred by coil and become the saturated vapor when
meet the water and air.
2, the heat is exhausted out of the tower by the tower by the top
fan; water is collected back to the bottom tank and circulates
continuously. The spray water is cooled down via PVC radiation fin
in the process of circulation, and flow is the same direction with
the fresh wind. The coil mainly takes sensible heat travel style.
3, the most benefit of this style is can avoid scale formation on
the outside of the coil. And this will apply especially to dealing
with high temperature fluid (e.g. 60°C) or the fluid need big
temperature difference (e.g. 60°C to 32°C).
Structure
Water cooling : When the fluid temperature is too high(surpassing
setting temperature), the spray pump automatically spray the water
on the pipe wall and form water film.Then the water film evaporats
to absorb heat(latent heat of vaporization).Part of spray water
becomes steam and is taken away by flowing air,the rest part
becomes water drops and fall on the catch basin for next
circulation The fluid inside the coil pipe is in closed loop and
won’t lose theoretically.The consumption of spray water is only
0.1-0.2% of unit flow.
Product Application
1. Cooling Tower +Heat Exanger Combination
Closer approach to wet bulb temperature and reduce fouling, highly
improve process efficiency
2. Air-Cooled Systems
10-20°C lower process temperatures ,less required space and lower
energy consumption
3. Once –Through Systems
Reduces environmental impact ,saving up to 95% of the cooling water
4. Reduced installed Cost And Space Requirements
Effectively combines the function of a cooling tower and heat
exchanger into one piece of equipment ,reduce required piping and
system complexity.
