With the advent of summer months, most people are looking for cost-effective industrial air cooler to keep their homes and business environments cool and comfortable. The industrial evaporative air cooler provides an effective and efficient way to cool homes and business premises. However, to work efficiently, proper installation and regular maintenance is important..
Here are a few crucial things you need to know before installing an industrial air cooler
First, it is essential that you choose an industrial evaporative cooler that can meet your needs. You also need to consider the following factors when installing one for maximum performance:
There is one drawback to an evaporative air cooler that should be considered before purchasing. This equipment is not suited for humid areas as it works best with dry air. Hence, for you to buy one, you need to be living in an area with a dry climate condition.
Since these coolers draw outside air in, they need to be installed outside of the house. You can have it mounted on windows, especially if you have a particular room that you want to cool. You can have it installed in attics, on roofs or at ground level for cooling an entire building system. industrial cooler also needs water to function well, so you will need to choose a location that is close to a water source.
• Different types of coolers
Principally, the evaporating cooling system was built to provide thermal comfort in hot and dry regions. Evaporative air cooler works by cooling the air with water. There are two main types of coolers;
– The Direct Evaporative coolers
These direct evaporative coolers are highly recommended for use in areas that experience severe dryness that is beyond the desired conditions. They come in two varieties;
1) Aspen Pad Coolers
Although the aspen pad coolers are relatively affordable than other coolers, they require the most maintenance. These 1 to 2-inch pads are made of synthetic fiber and wood shavings. Their cost varies depending on the thickness of the pads, with the thinnest being the cheapest. These pads need to be replaced with new ones after a year or two.
2) Cellulose pad coolers
These coolers use Cellulose cooling pads that are also popularly known as honeycomb pads. Although they are 8 to 12 inches thick, they allow air to move through at a higher velocity compared to Aspen pads. Cellulose pads have a corrugated pattern that pushes water to the pad’s air inlet side, where most of the evaporation takes place. While these pads are more expensive than the aspen pads, they are more durable and can last for many years.
– Indirect Evaporative Coolers
These evaporative air coolers are recommended for use when the air’s humidity level is in a comfortable range. The freshly filtered air first passes through a dry section of the system for cooling through an efficient heat transfer. This equipment comes in either two stage or three stage system.
1) Two-stage evaporative cooler: This machine has a two-stage evaporative cooler –direct and indirect. The direct system is used during the dry season when humidification is needed. The indirect one is used when the air needs to be cooled.
2) Three stage evaporative cooler: This system includes the direct, indirect and the cooling coil evaporating cooler. The cooling coil comes in handy during the monsoon season when there are high levels of humidity in the air, but still, dehumidification is required. Hence, when the fresh air passes through the coils, they control both practical and latent heat requirements.
• Water exchange
To prevent the system’s water from becoming too saline, install a bleed-off system to ensure that the cooler is only infused with fresh water. Installing the bleed off system helps to reduce the maintenance required for your system. However, it calls for about five additional gallons of water every hour.
An evaporative cooler’s capacity is measured by Cube Meter Hour (CMH). A small evaporative cooler system can be 6000 CMH while a whole house unit is usually 25,000 CMH or larger. To know what CMH your house needs, you will need to take the size of your home into consideration. For instance, the average three bedroom homes sit on 80 square meters of floor space with a ceiling of 3.5 meters. This equals to 280 cubic meters multiplied by the exchange that occurs 20 times. In this case, the 6,000CMH cooler is capable of replacing 100% of the air in the house every minute.
Another important thing you need to take into consideration when purchasing a cooler is its features. Preferably, go for an evaporative cooler with multiple fan speeds and a vent-only option. This way, you will be able to vary its operation based on the weather. You may also need to find a cooler with an air filter system to keep dust, debris, and pollen out of your home.
• Where is the system applicable?
An industrial air cooler’s function is to lower the heat and moisturize the air through evaporation. It is more cost-effective, efficient and eco-friendly than the traditional air conditioners. It is also more powerful than the typical outdoor fan. You can use this equipment to cool warehouses, workshops, manufacturing plants, hangars, and construction sites. You can also use it to cool gyms, garages, barns, patio area, athletic events, loading docks, and large tents.
7 Tips for installing an industrial air coolers
1. Mounting the cooler
An industrial air cooler needs to be installed outside your home or premise. You can fix it in different locations, depending on the type of cooler you have chosen.
• Roof-mounted: These are the most common air coolers, although they are more difficult to maintain.
• Wall / Window Mounted: It is easy to carry out maintenance on a wall/ window mounted unit. They also reduce the chance of house leaks. However, it is important to note that wall/ window mounted coolers blow chilled air in the house into a central area. They are highly recommended for small homes or bigger apartments with specially installed ductwork.
2. Installation height
Industrial air coolers should be installed at least 10 feet away or 3 feet below plumbing combustion appliance vents, plumbing vents, exhaust fan vents or clothes dryer vents. Make sure to keep fuel, yard chemicals, and solvents away from the cooler.
3. Check Float
Always check the float valve after every pump cycle. This way, you will ensure that the float is not set too high, causing the reservoir of water to overflow.
4. Maintenance distance
Provide at least 3ft of clearance on the side of the equipment that requires access for maintenance. This is a code requirement for all sides with electrical parts.
5. Use closed-eye Hooks
To hang your coolers safely and securely, use closed-eye hooks. However, take care not to lift the open-eye hook from the chain and leave your equipment unsupported when removing the frame.
6. The water line
An industrial air cooler needs a steady supply of clean water. Make sure to connect the water line to the system from an outdoor water source with cutoff valves. A cutoff valve is highly useful when you need to drain your system at the start of the winter season to minimize damage from harsh weather.
7. Power up
Before powering up your cooling system, confirm that there are no leaks. Also, fill any void spaces around the cooler to prevent cooled air from escaping the system. Once you have confirmed all these parts are set, you can switch it on. If you are unfamiliar with the electrical connections, it is highly recommended that you seek the services of a certified electrician.
Tips to maintain Industrial cooler
If you are looking for a cooling system for commercial buildings or industries, opting for industrial evaporative coolers would be a great option. Listed below are some tips that can help maintain industrial air coolers.
• Winterizing Your Industrial Evaporative Cooler
To ensure that the cooler does not rust, turn off the water supply connection, hose out the water pan and clean all the dirt and minerals that have settled in the cooler during the winter months.
• Regular Change of Cooler Pads
Change Cooler pads regularly Pads are pressed against the cooler. Leaving old pads that have dirt and minerals accumulated on them can cause the cooler to rust whenever rainwater flows down the cooler and runs down to the pad. To avoid rusting it always good to change pads during the fall instead of spring. Most people who fail the change the pads to save money ultimately have to spend more in the long run as they may have to change the entire cooler instead of just the pads.
• How often should you replace the industrial evaporative air cooler pads?
1) Reduced air flow
If your commercial air cooler is not cooling as much as it did in the past, a possible reason for this problem could be due to the particles that get caught in the pads. To solve the problem, an economical solution would be to replace the pads. However, it does not solve the problem; it is recommended to move on to more troubleshooting.
2) Types of materials
The type of materials used in the pads is one of the factors that decide whether a pad need to be replaced yearly or can last for years. While cellulose pads need to be replaced less often, pads made of cheap materials such as aspen may be required to be replaced each season.
3) Yearly Maintenance
Generally, pads may not be required to be changed every year. However, if the pad has lost its thickness or if the material has become frayed, it is best to get a new pad.
• Protection for Your Cooler
Keep Your Cooler protected Investing in a cooler cover will help prevent outdoor air from entering your home or building. Sometimes coolers have dampers. However, if your cooler does not have one, installing a cooler cover will help increase the life of your cooler and also save you money.
