Advantages of Closed Circuit Cooling Tower (CCCT)
Personnel Health Protection
Open cooling water system is subject to water pollution and, as a
result, the bacteria of miscellaneous sorts proliferate fast to
become a grave threat to human health by dissipating the bacteria
containing vapor. A popular disease from open water cooling system
is legionnaire that endangers human life by causing pneumonia,
which is especially true for people living & working in the
buildings with central air conditioners. Closed circuit cooling
tower has the largest proportion of cooling water circulating
inside enclosed loop, thus is not subject to water pollution. The
specially designed louvers not only reduce the limited spray water
drift to minimum level, but also effectively stop outside sunlight
and particles from entering the tower basin cultivating the growth
of bacteria.
Tube Scaling Prevention
Most scaling & fouling problems are caused by impurities brought
into cooling tubes by process cooling water, which will easily
damage heat rejection equipment like melting furnaces, some cases
of which involve personnel safety issues. For other equipments like
central air conditioner, generators, compressors etc, scaling
problems are one of the main reasons for lower operation efficiency
and souring maintenance cost. Closed circuit cooling tower
eliminates the scaling problems by running de-mineralized process
water inside the closed circuit cooling coils so that scaling
problem is reduced to the lowest level if not completely
eradicated.
Energy Saving
Variable frequency control ( VFC) is an option for flexible
adjustment of the number and speed of working cooling fans to
ambient temperature changes, the data of which can be preset at a
certain figure. During winter season, the spray water stops
automatically when ambient temperature drops to a certain level
using only a set number of operating fans to satisfy the reduced
cooling requirements.
Water Saving
CCCT system adopts 100% closed circuit circulation for process
fluid that saves water from loss in any form. Special baffle is
used to reduce unavoidable spray water loss to the lowest point
without negative impact on the cooling efficiency. The prominent
water saving nature is one of the most important factors deciding
the popular use of closed circuit cooling tower.
Space Saving
Closed circuit cooling tower is designed to operate within very
limited space, accounting for 1/4-1/5 that of open cooling system,
saving any form of ground construction. The effective drift
eliminator baffle enables closed circuit cooling towers to be used
indoors close to production line without wetting the groud.
Investment Saving
Closed circuit cooling tower has self-attached water basin and
fully enclosed cooling coils for preservation of cooling water that
saves any form of ground construction cost. Under open cooling
tower system, the large water pool is a necessity to supply all
process cooling water, and the related investment will be of no use
if the open cooling tower is to be re-installed to a different
site.
User Friendly
Yanye closed circuit cooling tower can be controlled via remote
control panel with clearly defined functional push-buttons and
digital display system. Automatic Light & Sound alarm system is
installed to remind the operator of extreme working conditions of
the cooling system for on time adjustment; VFC technology is
available for automatic setting of the cooling tower operation data
following ambient changes without human interference. Computer
control system is also possible under highly sophisticated cooling
system requirements.
Longer Life Expectancy
Instead of adopting wooden structure or PVC cooling fills, closed
circuit cooling tower is composed of copper or carbon steel cooling
coils, zink-aluminum galvanized steel case and stainless steel
structures etc that prolongs the trouble-free service life of
closed circuit cooling tower.
Easy Installation and Maintenance
The installation of closed circuit cooling tower includes merely
the connection of piping and electrical system that can be done
even by technical workers without training.
Due to the scaling-free nature of closed circuit cooling tower, a
great deal of human efforts for monthly or quarterly maintenance
can be saved, which are normally neglected due to the busy
production schedule and tend to cause sudden stop with long
accummulation of scalings.
Choosing closed circuit cooling tower comes to be part of our
responsibility for protection of life and environment with safe &
saving industrial cooling solutions
