SCF Closed Circuit Cooling Tower
SCF Closed Circuit Cooling Tower
1. Principle of Work
SCF closedcircuit cooling tower is a piece of highly efficient heat exchange equipmentthat is designed and made using sophisticated heat-exchange technology.
The air enters through the inlet in the bottom of the cooling tower, which is inan alternating counter-flow direction with spray water falling down, formingsaturated vapor in this process. The heat isexhausted out of tower by the fan and the water is collected to bottom tank andcirculate continuously by the special evaporator. As there is no heat transferpadding inside the closed circuit cooling tower, more space is saved toincrease coil's radiating area. This is suitable for cooling applications wherethe outlet water temperature is required to be close to the wet bulbtemperature.
(1). The efficient watereliminator is made of PVC, which is radiation resistant and long lasting. Itcan filter the drips from discharged air streams.
(2). Water is pumped over the evaporative coil surface area at 3.2l/m2 to ensure continuous wetting of theprimary heat transfer surface which enhances heat transfer efficiency andminimizes fouling and scale formation.
(3). For applications that might deposit soluble scale orsludge within the tubes, the cleanable header tube bundle provides removablecover plates.
(4). Easy removable air inlet grating avoids direct sunlight and prevents dustand dirt from entering the closed circuit cooling tower.
2. Advantages
The closed circuit cooling tower providesmany operational and maintenance benefits to the user by keeping the processfluid in a clean, closed loop.
(1). Protect process fluids fromcontamination.
(2). Maximize system efficiency byreducing fouling.
(3).Reduce system energy costs.
(4).Reduce system maintenance costs.
(5).Provide reliable, efficient, year-round operation.
As a result, our SCF closed circuit cooling tower is a product of choice forusers.

Piping size andinstallation must be in accordance with good piping criterion. All pipingshould be supported by pipe hangers or other supports, not by the closedcircuit cooling tower. External shut off valves may also be required if thesystem design necessitates the isolation of individual tower cells.
In general seasons,the performance of most closed circuit cooling tower will vary due to thechange of its environmental wet bulb temperature. Therefore, when the change ofenvironmental temperature leads to the difference of liquid temperature, inthis case, capacity control will be required.
Fan periodicity operation is the simplest method of capacity control for ourclosed circuit cooling towers, normally used in multi fan unit system or multicell unit system. In some circumstances of low requirement on outlet watertemperature control, fan periodicity operation can meet with temperaturecontrol requirement, and also, is easy to handle. Using two-speed fan canprovide substantial energy savings when compared to simple fan periodicityoperation.
At below freezingambient temperatures, the closed circuit cooling tower can experience heat losseven when the circulating spray water pump and fans are not operating. Withouta heat load on the circulating fluid, coil freezing can occur even at fullflow. Protective measures are readily available to avoid potential freezingproblems. Where the system w
