Cooling Towers in New York and New Jersey
Cooling towers are considered a heat rejection device, which means they get rid of heat by use of a machine or process — or both. You might see them in the form of huge towers or large, bulky machines. The type of cooling tower an area needs depends on the area being cooled and the type of activity which takes place within that space. There may also be zoning and other government regulations related to what type of cooling towers you need and when.
When and Where to Use Cooling Towers
Typically, you’ll find commercial cooling towers on buildings like oil refineries, manufacturing plants, hospitals, petrochemical and other chemical plants, nuclear power stations, and the like. If you have a process related to energy you’re likely going to need some type of cooling towers, though the size of your cooling tower will depend on the type of operation you run.
Edison Parker sells, maintains and services cooling towers all over New York and New Jersey, for both small and large operations. With large, commercial buildings generally consisting of large HVAC systems, those cooling towers are essential to keep the system running right: Cooling towers work overtime in industrial spaces to keep all systems running smoothly.

Cooling Towers
There are several factors you need to think about when it comes to choosing a cooling tower. The first is to make sure that it’s the right size for your operations so that your facility is well taken care of. If you get a product that is too big, you’re expending energy for a cooling tower you don’t need. On the other hand, if your cooling tower is too small, chances are you’ll overwork the system and require extensive and expensive repairs. cause premature break, or expen you get something too small you could end up hurting the entire system, which is going to mean lots of expensive repairs.

Different Types of Cooling Towers
There are several different types of cooling towers that cool mechanical systems you should consider when you are looking to set up your system. These are crossflow, counterflow, and hyperbolic. You can also look at airflow varieties, which come in induced draft and passive draft.
Let’s take a look at each one and see how each one is unique:
- Crossflow Cooling Towers - These are splash fill towers that breaktowers break water into small droplets and that push air horizontally over the stream of water. They’re relatively expensive to get started, and they’re susceptible to frost, but they are quite simple to maintain..
- Counterflow Cooling Towers - These are splash fill towers as well, but use vertical paths for the air flow. They’re generally smaller but also quite expensive because they need a great deal of energy in order to get them started and run them going.
- Hyperbolic Cooling Towers - These look like large chimneys and they allow colder air from outside to push down into the warmer air inside. They have a splash fill at the base of the tower and upward air sprays over this system and cools. They’re actually quite efficient and don’t need a lot of resources, which makes them great for larger systems.
- Induced Draft Cooling Towers - This type of system uses mechanical pressure, such as fans, to push air up or they can use blow-through or draw-through.
- Passive Draft Cooling Towers - This type of system uses warm air moving up the chimney of the tower to pull the air through. It lets all of this happen naturally and can be found with any of the water tower types.
Choosing the Right Cooling Tower for Your Needs
Here are some components you want to look at to make sure you’re getting a quality cooling system that is the right size for your needs:
Heat Load - The amount of heat energy that is required to keep an acceptable temperature.
Approach - The temperature of the water that is leaving the cooling tower once you subtract the ambient bulb temperature.
Range - The difference between the water temperature going into the cooling tower and the temperature of the water going out.
Wet Bulb Temperature - This is a specific type of temperature that comes from a thermometer that’s been covered with a wet cloth and then cooled with air.

How to Care for Cooling Towers
There are several aspects involved in caring for cooling towers and it starts with keeping the entire thing clean. This is going to be the most important step, because it means everything else that happens within (or around) the tower is going to be much easier.
Removing scale deposits, or calcium deposits, is considered essential, as there are plenty of minerals in the water used in the cooling tower system. These will cause limescale buildup — which can cause the system to start breaking down. This is because the limescale affects the mechanical components, rendering them less effective.Eventually this can lead to complete malfunction.
Monitoring air flow is another important aspect because improper air flow is going to reduce your efficiency. If this goes on for a long time, blocked airflow can even cause an entire cooling system to break down. Many things, including scale and debris falling into the cooling tower could interrupt your air flow so make sure you’re checking if you notice a problem.
Next, chiller tubes, which contain the refrigerant in the cooling tower, need to be fully cleared at all times. Much like the drains in your home, you need your chiller tubes to be free of anything that could interfere with the flow. They can attract mud, algae, scale deposits and slime, so make sure you’re checking frequently and removing debris.
The water pump in the mechanical room or near the chiller tubes, needs to be working properly in order to keep everything else going. Make sure you maintain the pump to keep the operations as simple as possible. The easier it is for the pump to work the more efficient it’s going to be.
Finally, make sure the water is properly treated and that you have the right water quality throughout your system. The water is used as a coolant to cycle through the tower (depending on the specific type that you have) and keep the components at the right temperature. It must be treated through the removal of dirt, debris, scale, and other particles that can get into it throughout the process of cycling through. It also must be replaced frequently as water is lost through the process of evaporation, blow-through, draw-down, and others.
If you don’t treat the water properly on a consistent basis, those problems with debris and limescale are going to build up consistently over time in an unhealthy way, and that’s going to cost you time and money.

FAQs on Cooling Towers
How Can I Increase Cooling Tower Efficiency?
In general, the best way to increase your efficiency is to make sure that your cooling tower is operating at full power and isn’t being blocked anywhere along the way. Working with a cooling tower repair service will help you to keep your tower working right.
How Often Should You Clean a Cooling Tower?
You will want to hire aa hire cooling tower repair company at least twice per year to make sure that your system is working right and is completely clean and clear. If you have any problems with the tower or it doesn’t seem to be efficient then you may want to look for a professional cooling tower maintenance service.
How Much Water Does a Cooling Tower Use?
While the amount could vary slightly, you’ll generally find that a cooling tower uses 2.4 gallons of water per minute per 100 tons of cooling just in evaporation.
How to Calculate Cooling Tower Efficiency?
You’ll need a little bit of math skill in order to calculate the cooling tower efficiency or how much quality you get from the energy it uses. In general, you will take:
Range/(Range+Approach)x100
Or you can take:
(Hot Water Temperature-Cold Water Temperature)x100/(Hot Water Temperature-Wet Bulb Temperature)
Glossary
Windage/Drift - These are the water droplets that come through the cooling tower and contain a great deal of impurities, which is why this must be limited through drift eliminators or warmer temperatures.
Blow-Out - More water droplets can be lost because the cooling tower is actually open at the top, which means that the water can be blown out by wind or could splash or mist. Additional devices must be used to account for this. These include wind screens, splash deflectors, and water diverters to keep loss to a minimum.
Plume - Exhaust air that leaves the tower is considered the ‘plume.’ It’s generally visible because the water vapor hits the cooler air outside of the tower and condenses, which could cause fog or ice. (This water is considered pure.)
Draw-Off/Blow-Down - Circulating water flow that is discharged from the system to keep the impurities low are called either of these terms. The specific concentration is maintained by the system and those watching the process.
Make-Up - On the other hand, this is water that needs to be added in order to accommodate for any water that has been accidentally lost (through evaporation, blow-out, etc.).
Approach - This refers to the difference in the temperature for the cooled-water and the entering-air wet bulb. This will allow the system to do what it needs to do.
Fill - Fills increase the contact surface and contact time for water and air, which helps with the heat transfer process. More efficient towers use different types of fill such as film type and splash type.
Full-Flow Filtration - This is the best option for filtration and strains out particles from the entire system at all times.
Side-Stream Filtration - This option is relatively effective but only filters a portion of the water all the time.
Cycle of Concentration - This is the maximum multiplier for substances that can be in the circulating water compared to the ones in the make-up water.
Blow Through Cooling System - This type of system uses a fan placed before the burner.
Draw Through Cooling System - In this type of system a fan is placed after the burner.
