After going through all the hustle of finding alternative means of cooling and air conditioning, now that you have decided on cooling towers, you have our attention. There are a couple of very important things you should have in mind while deciding on the best cooling tower to install that will meet your needs.
Here are the things you should consider when buying a cooling tower from Sara Cooling Tower;
- Cooling duty
The purpose of the cooling tower is cooling, hence the importance of knowing how much heat energy should be lost.
The magnitude of cooling duty will determine the type and design of cooling tower appropriate for the job.
The more the cooling duty the better and bigger the cooling tower and the more money will be spent.
Bigger cooling towers have their demands too but there will serve their purpose religiously and 30 years or more is a good time limit of expiry.
Factors to consider if the cooling tower will meet the cooling duty;
- Volume of air flow
- Fan energy
- Pump energy
- Material of construction
- Equipment selection
- Water quality and quantity
- Environmental conditions and Aesthetics
The industrial site, building, school, oil refinery plant, hotel, steel mill or whatever it is requiring cooling or air conditioning environment matters.
The weather is a major consideration, as during winter you need cooling towers with specific cooling parts like cold basin heaters to avoid freezing of the water.
The draught is also a factor to consider as at some point it helps with the cold air flow while in the process it allows in impurities and materials carried by it.
Aesthetics may sound petty and irrelevant but it is a major factor. Does the type of cooling tower blend with the architecture.
It is important to have a cooling tower design that is compatible with the architectural design of the office building, hotel, hospital or school.
Most of them are situated indoors, against walls or in between building hence the need for it to blend as it is not meant to attract attention to it. Most cooling towers in the oil refinery plants, steel mill, or electricity plants do not take this into consideration as much.
When deciding on the cooling tower you want or that is fit for your needs also consider the capital you have. Different cooling towers cost differently.
Consider factors like;
- Installation cost
- Electrical wiring to the fan and pump motors
- Piping to and from the tower
- Water costs
- Water treatment
- Maintenance cost of the tower
- Cooling tower fillers
- Maintenance requirements
Under maintenance requirements keep in mind the cooling tower you choose need constant check-up for perfect performance.
General cooling tower maintenance involves;
- Draining of the sediments accumulated at the bottom of the basin.
- Getting rid of the algae if any grows in the cold water basin
- Check on the fan and gears if they are running smoothly
- If the make-up water is flowing in time to avoid damage to the tower
- If there are any piping issues to avoid water loss as it is expensive
- Running of water in the fills and if the fillers are perfect for your tower
- Availability of spare parts
Any machinery is bound to need repair once in a while and the cooling towers are no different. The parts used maybe of low quality and can wear out easily.
We at Sara Cooling Towers have any part you could possibly need and our products are used all over the world. You can trust us and your cooling tower will have great quality parts.
Most of the spare parts required are;
- Gear boxes
- Cooling tower pipes
- Drift eliminator
The bigger or bulk parts do not require spares as frequently as the smaller part.
The location of the cooling tower plays a major role. The space available for the cooling tower can help you choose the type. The Crossflow cooling tower needs enough space to be erect while the FRP cooling tower can be fixed in between buildings
When choosing the cooling tower and having the location in mind know that the towers have some vibrations and there is sound produced as they run.
The drift coming out of the tower can cause some mist air which may affect driving at near roads.
Determinants of cooling tower location are;
- Structural support requirements of the cooling tower
- Conformity with local and building codes
- Rigging limitations
A cooling tower can be located in an open space with free air circulation or it can be located indoors or in enclosed spaces.
- Materials of construction
The material used for the cooling tower is important as it has to meet the expected water quality and atmospheric conditions.
The materials available for the cooling towers include;
- Wood which is used widely for most parts in exception of the hardware. The wood used needs to be treated to prevent attack by organism like termites and fungi.
- Plastics includes the FRP cooling towers. It also used for components like fans, fillers, louvers and the piping system.
- Concrete, masonry and tile. Concrete is used mostly in cold water basins especially in the field erect cooling towers of big plants. The masonry and tile is used when there is need for the cooling tower to blend with the architecture.
- Metals and not used normally but are involved in with the small and medium sized parts formation especially steel. Others like bronze and brass are used for fitting and tubing material. Stainless steel is mostly used for sheet metal, drive shafts and cold water basins. These metals are well coated to prevent rusting.
Other minor factors you should put into consideration are; safety features and safety codes, general designs, the rigidity of the structures, effects of corrosion, deterioration experience and the reliability of the manufactures.
Having all the facts straight as they are laid down for you now the decision making is all yours. Cooling towers are the best investment you can make for cooling purposes and also for heating, ventilation and air conditioning. We believe that now you are ready to make the purchase for whatever is needed for you cooling tower.
