How we choose best Cooling tower manufacturers
A Cooling Tower is the best mechanism to treat your equipment and save water. People prefer different cooling tower manufacturers for their different tower design and needs. You need a good system from Industrial Cooling Tower Manufacturers if you want to make a choice about a new cooling tower for your industry.
A change in design, structure or the total system may warrant people from contacting industrial Cooling Tower manufacturers for a new project.
Whatever the case, we have many variety of cooling towers on the market to choose from. A decision to buy the correct tower system for your building can ensure its efficacy, operation smoothness and saves money.
We have totally different perspective from the manufacturer’s and the buyer’s viewpoint. While system designers consider environmental condition, cost and cooling capacity, building owners prefer to have an affordable tower which is maintenance free with a good lifespan.
These days, tower makers build them from fiberglass say an "FRP Cooling Tower Manufacturer" can give us longlasting tower systems. Those who have known about various forms of cooling towers built by industrial Cooling Tower manufacturers and suppliers, newer technologies including machines, film fills and designs always serve as an inspiration and they can suit your application.
Determining a Cooling Tower Manufacturer for your tower Design:
Choosing a Cooling Tower Manufacturer greatly depends on the material used in tower production. Every tower has to go through a water drenching process which overtime harms efficacy of the components and its salt or sheer hardness will corrode the material, create biofilm and the usual seam leak from expansion and contraction, hard water air present in the atmosphere, and the like.
Selecting your cooling tower materials properly can expand its life and help combat those environmental effects.
We have several varieties of cooling towers on the market like galvanized steel, stainless steel and fiberglass reinforced polyester.
Let’s go through the material first:
Galvanized steel: Traditional cooling towers use steel sheets coated by zinc but they are vulnerable to rust, corrosion and pH problems. Also seam leak and biofilm hazard become apparent. These towers have just 5-6 years life expectancy and are a low-cost option.
Stainless steel: A better investment over galvanized steel, stainless steel cooling towers generally work trouble-free about 10- to 15-years. They are used in harsher weather conditions where water hardness is greater. But seam leakage can be a problem from expansion/contraction that occurs from weather exposure.
FRP: Fiber reinforced plastic or FRP towers are the most durable of all and can go beyond a 30-year life expectancy in some brands that an FRP cooling tower manufacturer can provide. FRP towers are more corrosion proof, seamless, come with UV protected coating and leakproof due to their bathtub design and there are no joints in a fiberglass constructed tower. Hence, no leak problems arise. FRP is also resistant to scale, and to biofilm, which eats up all steel towers.
Drive Support: Tower blades run on a drive type to blow out hot air. But the choice can be costly if a proper drive type is not chosen wisely.
There are three typical drives used in cooling towers.
Belt drive: The fan rotation is done by the belt and it costs low. The belt is not expensive but a new replacement needs tension adjustment, the bearings also need change and the pulleys wear out after about a year.
Gear drive: These are the reliable components of a tower fan. Because gear systems are fully mechanical, they are sturdy and hence longer running. But gear drives require oiling and usual maintenance. However, they are more reliable than a belt drive. Oil check, greasing and inspection of the shaft is a must.
Direct drive: The best form of a drive is a direct drive as minimum service is required. It is belt free and no adjustment is needed owing to fewer parts between the motor and the fan.
Configuration of Tower: Let us also read about the configuration types of cooling towers and their flow control types.
Counter-flow: The air suction from the fan is against the falling water. The tower has a smaller area of coverage with even air distribution through the fill material. This tower type can also include pressurized water distribution.
Cross-flow: As the falling water flows the fills, the hot air that flows across falling water is pulled out by the fan with gravity distribution. This type has a large area coverage.
Other Important Factors to Consider before you buy a tower of your choice:
1. How much cooling load it can contain.
2. Flow rate of cooling water.
3. Water Temperature entry and recycling.
4. Wet Bulb Temperature (WBT)
5. Lowest temperature after treatment and relative humidity.
6. Space coverage
7. Noise level restrictions
8. Bearable water quality and Cycles of Concentration.
An appointment with an FRP Cooling Tower Manufacturer or select few Industrial Cooling Tower Manufacturers and suppliers will expose you to the attractive designs and additions they can provide. However, cost wise and quality wise, FRP towers can be a better option. Still, do a little research because fiberglass quality may vary greatly from one manufacturer to the other.
