Air-cooled Fluid Cooler (ACFC) is an American Technology High Efficiency dry cooling system. ACFC works on principle of rejecting heat from hot fluid to ambient-air directly through heat transfer coils. This is in contrast to conventional method of cooling using shell & tube heat exchanger & wet cooling tower system.
The obvious advantage of ACFC is that it does not work require any water after its first charge. This is completely a closed circuit system. The hot fluid (water) from the source is made to pass through finned surface heat transfer coils & using the heat is rejected to ambient air passing through coils using axial fans.
The ACFC can be designed to reject heat from as small as 100 KVA DG Sets to as large as 300 MW power plants.
Why ACFC ? :- Eight – Special Reasons
1. |
Water Consumption in Air-cooled Fluid Coolers system |
“Nil” with Air-cooled system after its first charge of water / fluid there is hardly any necessity. The same water / fluid is being circulated in the closed circuit system and is not exposed to the atmosphere for any loss or evaporation. Temperature below freezing will require anti-freeze / glycol. |
|
2. |
Range & type ofAir-cooled Fluid Coolers |
Air-cooled Fluid Coolers (ACFC) are available in two-different type of series (Model : VW, PL) with unlimited combinations. The heat-transfer coils (Fin-spacing, Row-deep, Face-area, Air-velocity, Motor-power etc.) are selected on the basis of operating conditions of cooling systems. |
|
3. |
Cost of Water Softening Plant |
Water-softening system is not required once the potable drinking water is filled in the fluid coolers there is no water consumption at all. This kind of water is almost easily available everywhere. |
|
4. |
Dirt / Dust overAir-cooled system |
Dirt / dust may accumulate at finned surface heat-transfer coils in bad weather conditions during storm of dust in the air. Periodically dirt / dust can be washed with water pressure hose like washing a car radiator, or it can be cleaned with high pressure air if available. |
|
5. |
Scale formation in Air-cooled System |
“Nil” as the water filled in the system is already clean. This water being circulated again and again, without any evaporation, therefore system is scale-free and there is no need for cleaning of tubes at all. |
|
6. |
No De-ration of Cooling System |
Air-cooled fluid coolers selected at highest summer ambient temperatures therefore there is no fear of any de-ration. Through our Air-cooled system full capacity of plant can be utilized at peak load conditions. |
|
7. |
Saving Electricity during mildweather |
Fan motors of air-cooled fluid coolers will save substantial amount of electricity, during winter season, cool nights and mild weather conditions. These fan motors can be connected for automatic operation with water-line- thermostat, to switch on / off for saving of electricity. |
|
8. |
Maintenance Cost very negligible |
ACFC – Air-cooled Process-Fluid Coolers require very little maintenance except yearly routine inspection of electric fan motors. If dirt accumulates at finned surface heat-transfer coils in bad weather conditions it can be very easilv cleaned as mentioned above. |
