EJECTION NOZZLES
THE EFFECT OF EJECTION IS CREATED BY THE STREAM OF WATER DROPS PROCEEDING UNDER PRESSURE FROM
SPECIAL EJECTION NOZZLES
PROVISION OF THE EXTENDED COOLING SURFACE
SYSTEM CLEANING WITHOUT STOPPING THE COOLING TOWER
WORK MAINTENANCE IN THE DISCRETE MODE
DON'T FREEZE AND DON'T SHATTER: nozzles are
located at an angle, after work stoppage liquid is
removed in natural way, restart doesn't require
preparatory works
4
FILTRATION
Mud collector-filter
Cleaning from heavy mechanical impurity with a density
>1000 kg/m ³ and size > 15 microns, and from easily
emerging pollution
Filter of thin cleaning
Preliminary or final filtration with the removal of the
weighted and dust-like particles, filtration capacity from
200 to 1 micron
- The minimum hydraulic resistance (0,08-0,15 atm), not depending on the quantity of gathered pollution
- Working at water flow speed from 0,5 m/s to 2,5 m/s
-Removal of gathered pollution without stopping
the filtration system
- Expendables and special service aren't required
- No grids and filtering materials
5
DROP CATCHER
DROP CATCHER ALLOWS MINIMIZING WATER REMOVAL THAT RESULTS IN REDUCTION OF COSTS. FEED IS NECESSARY
ONLY FOR EVAPORATION COMPENSATION (1 - 2% from the total amount of used water)
-
RESISTANT TO RAPID TEMPERATURE CHANGE
- IT IS NOT A SUBJECT OF BIOLOGICAL INCRUSTATION
-
- EFFICIENCY OF DROP CATCHING – 99,99%

EGECTION COOLING TOWER CASE MATERIALS
Heated water = 60°С
Chilled water = 25°С
Heated water = 38°С
Chilled water = 26°С
-
THE CASE IS MADE FROM THE REINFORCED POLYMERIC
MATERIAL
LIGHTWEIGHT
IT IS NEUTRAL TO CHEMICAL INFLUENCE AND CORROSION
-
THE CASE FROM STEEL WITH THE CORROSION-RESISTANT
COATING
RESISTANT TO MECHANICAL DAMAGES
DOESN'T REQUIRE SPECIAL SKILLS AND MATERIALS TO
REPAIR
7
LAYOUT OF COLLING TOWERS
Heated water = 32°С
Chilled water=24 °С
-
CONSUMPTION OF WATER 100 – 300 M³/ h
-
CONSUMPTION OF WATER IS 2000 M³/ h
-
TEMPERATURE DIFFERENCE FROM 43 to 28 °C
AT t = 40 °C and HUMIDITY 40%
-
SYSTEM AUTOMATIZATION REDUCES ENERGY
CONSUMPTION AND SIMPLIFIES THE OPERATION
-
MONOBLOCK SYSTEM WITH MOUNTING ON THE ROOF
OF THE PRODUCTION CASE
-
CASES OF THE COOLING TOWER ARE LOCATED OVER THE
PUMP STATION

AUTOMATION SYSTEM
THE AUTOMATION SYSTEM ALLOWS SAVING FUNDS BY REDUCTION OF POWER CONSUMPTION AND COSTS FOR
SERVICE STAFF
SYSTEM TAKES OVER SUCH MAJOR FUNCTIONS AS:
MAINTENANCE OF THE CONSTANT PRESET TEMPERATURE OF CHILLED WATER
MAINTENANCE OF THE CONSTANT PRESSURE IN THE PIPELINE, EVEN AT VARIABLE NUMBER OF CONSUMERS
WATER LEVEL MAINTENANCE IN THE STORAGE TANK (SYSTEM FEED)
9
POWER CONSUMPTION
UNDER EQUAL CONDITIONS OF THE
ENVIRONMENT, EQUAL OPERATING TIME
AND EQUAL THERMAL LOADING – OUR
EJECTION COOLING TOWER HAS AN
OPPORTUNITY TO WORK CYCLICAL
AND TO CONSUME MUCH LESS ELECTRIC
POWER, UNLIKE FAN-ASSISTED COOLING
TOWER WITH THE CONSTANT OPERATING
MODE AND POWER CONSUMPTION.
BENEFIT FROM OPERATION OF THE EJECTION COOLING TOWER – IS
OBVIOUS AND ALREADY TURNED BACK PROFIT FOR ALL OUR CLIENTS! ! !
10
ADVANTAGES OF THE EJECTION COOLING TOWER
(comparison of the standard fan-assisted and ejection cooling tower)
FAN-ASSISTED
EJECTION
The sprinkler collapses
No sprinkler
Restriction on temperature of heated water +65 °C,
restriction on temperature difference
Has no restrictions on temperature and differences (to t ≤
+90 °C)
Fan engines blow out, unbalance, high noise level
Quiet in due to absence of fan
Requeres sufficient feed for water temperature
decrease
Feed for compensation of the evaporated water (1-2%)
Restart during the winter period requires the
preparatory works
Works in a mode of frequent stops/starts in any time of the
year
The efficiency of the cooling tower depends on fan
efficiency
The efficiency is higher, than standard fan-assisted cooling
towers and it is not changed during the whole service life
Power consumption is constant and depends on fan
power
Power consumption is lower up to 30%
Heat removal is adjusted by channeling effect and the
frequency of fan operation
Heat removal is adjusted over the wide range, with decrease
of power consumption
11
MODERNIZATION OF FAN-ASSISTED COOLING TOWERS
Modernization of cooling towers is performed due to dismantling of fan and sprinkler, with installation of ejection
channels into air collector windows of the outdated fan-assisted cooling tower. Then the new water distribution system
between collectors is mounted.
IT ALLOWS:
 TO SAVE ON DEMOLITION OF OUTDATED COOLING TOWERS AND CONSTRUCTION OF THE NEW ONE
 TO REDUCE COSTS ON THE OPERATION AND MAINTENANCE OF NEW SYSTEM SUFFICIENTLY
 TO INCREASE THE POWER AND SYSTEM PERFORMANCE WITHOUT EXTENSION OF THE AREA
12
EFFICIENCY AND RELIABILITY
- Simplicity of construction
- Operational reliability
- Availability to survey and prevention
- Absence of ice formation during the winter period
- Doesn't require the highly skilled service personnel
- Automatic temperature control of chilled water and pressure in system
-Continuous operation as well as at frequent stops during winter period
- Absence of vibration and low noise level, is reached by absence of moving elements in
system
- The dimensions of unit are significantly less than fan-assisted and towered cooling tower
have, power is much higher
- Possibility to install in any place, on factory territory or on the roof of production building
13
ECONOMIC BENEFIT
- Cleaning of nozzles without stopping the cooling tower
- Absence of the basin (the underground tank) reduces the construction period and cost
estimate
- Sufficient decrease in costs for cooling tower service due to absence of the fan
- Reduction of power consumption and costs for service personnel due to system
automation
- Reduction of pipeline length due to arrangement of cooling towers closely to production
buildings
- Feed for water temperature decrease isn't used
- Capital costs are 1,5-2 times less (in comparison with standard fan-assisted cooling
towers)
- Operation costs are 40 - 50% lower
- Quick payback of the cooling tower due to decrease of the costs for water consumption
and water disposal The cooling tower is paid back in first - third month after operation
