There are many ways through which individuals can acquire both direct and indirect cooling, but one of the best and the most effective ways to do so is by investing in a fin fan cooler. These types of coolers have gained a huge amount of importance over the past few years due to the amazing range of benefits they have to offer in not only the short, but the long run as well.

No Sound Emission

Another major benefit of such coolers is that they hard make any sound. Even if they do, the sound levels can always be reduced. While other cooling devices are known to make a lot of noise on a day to day basis, a fin fan cooler is something that keeps the external environment peaceful whenever required. Due to this fact, it is much better in comparison with many of its opponents, such as air conditioners, for that matter. Investing in these coolers really pays off when no loud and continuous sounds come through it, especially at the time of the night when everyone requires silence.

Easy to Install

The installation of a fin fan cooler is rather easy in general. While a lot of people may think that it should take up a lot of time, it really does not and can be winded up quite soon. Asking properly installers in order to carry out the job is hardly expensive and gets the job done within a day’s time; hence, it is quite recommended. On the other hand, these coolers can be used for both residential as well as commercial use. Therefore, people can always decide whichever they prefer more. With a wide range of different kinds of such coolers present these days, it is very important to choose the right one that fulfills a task at hand.

Long-term Durability

These coolers are available on sale in the market as well as at numerous online stores in different parts of the world. Before purchasing them, individuals should be aware of all that they have to offer. These coolers are highly durable and can last for a long period of time without getting deteriorated. Most importantly, these coolers are better suited for high pressure usage, such as with gas engines and everything as such, when it comes to industrial and commercial usage. Hence, people should keep this important information in mind.

Cooling Spacious Areas

A major reason for investing in a fin fan cooler is the fact that it allows the overall surroundings to become cooler in general. A lot of other machines and devices have been made to carry out this task but these cooler stands out due to this impressive performance and high end features. Moreover, they can cool down large spaces within a short period of time. Generally available easily on sale these days, individuals should not let go of this exclusive source for direct cooling whenever required. These can be installed anywhere, according to the preference of an individual.

Removal of Dust Particles

A fin fan cooler is also known to completely eliminate the entire amount of dust from the air. This makes it a very suitable equipment to purchase as everything requires clean and fresh air to breath in at all times. Dust particles can be found in abundance in the air and in order to remove them, these coolers prove to be rather handy and very useful in both the short and long run. The existence of dust in the air, if not removed quickly, can lead towards many illnesses, diseases as well as allergies that can deteriorate anyone’s condition. Hence, these coolers are most definitely worth buying. 

Buying an Air Cooler – Guide

An air cooler is essentially an appliance that cools down the heat in the air and makes it comfortable for people to breathe in stifling atmospheres. They are very commonly used in many South Asian countries during the summer seasons. Many Western countries also put it to use during summers when it gets a bit hot. Air coolers come in a variety of forms, shapes and sizes and since there is so much variety available on the markets currently, it becomes very hard for customers to decide which one is best for them. In order to make the right purchase, read the following buying guide for air coolers.

A very common and helpful feature in an air cooler is known to be the oscillating fan head. This simply means that the head of the fan (which is pelting out cool air) is able to move to and fro and can rotate easily in all directions. With the help of this, one can ensure that most of the ground is easily covered with a single fan. The larger the fan head and the farer the head rotates, the more area will be covered.

Speed settings are fairly common as well. The feature means simply what it says – that people are able to adjust the speed at which air coolers operate. For example, if it is way too hot one day, one can turn up the speed of the fan and make it pelt out cooler air at higher speeds. On the other hand, if one simply wants a cool atmosphere, they can turn the switch to the normal temperature. Some speed setting also allows one to actually control the temperature inside the room as well.

An air cooler also comes with a timer function. Many people use this function in a variety of South Asian countries. Since it gets really hot there, people usually go to sleep with their air coolers switched on during the night. However, before they go to bed, they set a timer on the fan so that it shuts itself down at a specified time or after a specified period of time. Some air coolers also have the ability to turn themselves on when a proper timer is set. 

Some air coolers, especially the ones that come from high tech firms, also provide remote controls to manage the air cooler without having to get up. The remote control allows one to control almost everything related to the functions of the cooler. For example, one can turn it on or off sitting exactly where they are or thy can also turn up the temperature or turn it down. They can also move the head of the fan in the direction they prefer. Having a remote control will make air cooler much easier and simpler to use. It is a very user-friendly tool that is likely to highly influence the final purchase of the cooler.

Another feature greatly necessary for homes where either pets or children reside, is the existence of a grill or mesh that disallows one to touch the ‘wings’ of the fan inside the cooler. This is very important since the two groups mentioned may try to touch the rotating wings when they find them curious. Safety is very important while purchasing air coolers and it is highly suggested that whether one owns pets or has children or not, they should get air coolers with grills.

These are the most important things to keep in mind when purchasing an air cooler. Of course, there are other aspects like price and quality but as far as features are concerned, the article has covered all the major ones marketed today.

Why use a Process Skid?

Ever since the process skid has been created, many high end tasks have been made easier to carry out in the short as well as the long run. This is the best alternative that has been created for using traditional construction methods, which are quite effective in their own way but just have become rather outdated due to the fact that new technology has better uses in today’s world. For the purpose of carrying a complete process system, skids can be sued whenever required as they have been specifically made for the task. In order to support larger individual parts, a wide number of skids can be combined together for the purpose of making larger process systems in the long run.

Accessibility

Another very prominent benefit of using the skid system is that skids are always constructed somewhere offsite and this has many advantages in both the short as well as the long run.  This means that the other operations are not affected in any possible way, which is always what is required in the first place. This benefit is why skid system is really being used in different parts of the world due to many different reasons. The usage of this system is by far no hindrance for other operations at a plant, and thus, it is a top suggestion.

Easily Portable

It is important for people to know that the process skid is much portable in comparison with the traditional construction methods, which really could not be taken from one place to the other easily. Amongst one of the chief reasons for using this kind of process system is the very fact that they enable portability whenever required. These units are particularly built in frames, and this is what mainly allows them to be so portable in the first place. Therefore, individuals now do not have to worry even a bit about the transportation process since these systems actually take care of it all.

Possible Connections

Used mainly in plants, the process skid system makes sure that all the connections in the plants are made easily. This is much better in comparison with the task that traditional systems carry out since instead of making such connections easier and faster, they make the connections long and spread all over the plants in general. This can be fully eliminated with the skid system and is the reason why skid systems have become so popular in a short period of time. The connections are all found in a single spot within skids, and that is why they are always highly recommended.

Layers of Equipment

Those who are interested in setting up more equipment in the skid system should be aware of the fact that they can easily do so. This is due to the fact that these systems are highly known for allowing people to set up more and more layers of equipment, whenever they are required. However, only some equipment should be fit into these systems and over-layering may make everything congested. Different sorts of skid systems have various design that all can be made according to adjust a good amount of equipment in it.

The Conclusion

Usually found in the middle of plants, the skid systems are what connect everything together in a plant in order to provide individuals with a good amount of accessibility whenever they want or prefer on a day to day basis. As a part of its features, these systems are what bring everything together in the process of construction within a plant or anything as such. It may be placed someplace else at times, but mostly, these are found always within the center and everything is a skid system is supposed to be connected from one way or the other; hence, making it a very convenient system for all plants.

Tube Bundle – A Brief Description of its Parts

The usage of a tube bundle has increased on a large scale over the recent years since it has a lot of industrial applications and is known to be the best way for the transferal of heat. These bundles are available in a wide range of different sizes, diameters, shapes, materials as well as designs. Choosing the most appropriate one depends on whichever industrial application it has to be used for in the first place, which has to be decided by the user. There are many parts of these bundles, all of which are unique in their own way and without them; these bundles tend to not work as efficiently as they do otherwise.

The Width

The thickness of the tube is another factor that should be checked out before buying these bundles for any sort of uses, particularly for heat exchange. Certain standards of tube thickness have been set for people to see and decide which one they prefer more. The thickness of tubes actually makes the outer walls heavy, making the bundles much more solid and efficient in the long run. For all that these bundles have to offer, these should definitely be used for heat exchange and all the industrial uses related to it in general.

The Material

Individuals who are going ahead in order to use this bundle should always check out the tube materials beforehand. This basically ensures the material that has been used in the manufacturing of the bundles in the first place. Mostly, they are made of cooper and that is easy enough to find. However, in case these ones are not available for some reason, there is a wide range of other tube materials which are available for the convenience of users. These materials generally are inclusive of carbon steel, titanium, cupro-nickel and many more which are equally as effective.

Bolt Holes

On the other hand, these bundles also are inclusive of bolt holes which can be found in abundance. People should be aware of the fact that the bolt holes always tend to go around the tubesheet and on through it, which is a common misconception amongst a lot of individuals who decide to use the tube bundle for a variety of different reasons. However, some of these bundles many have bolt holes and on the other hand, some may as well not have them too. Although knowing the size of the bolt holes present in these bundles along with their sizes and length is exceptionally important.

Tube-sheets

Being a part of the tube bundle, the tubesheet thickness is something that can be easily measured. While the thickness may vary always, individuals who wish to use these bundles can always select the type of tubesheet thickness which suits them best and that usually tends to depend on the type of application it is being used for. The diameter can also be checked without having to face any issue and for those who are interested in knowing the actually thickness of the tubesheet which is majorly found in these bundles, it varies from 5” to 3” thick at best.

The Straight & the U Tubes

While some bundles have straight tube whereas the other ones are “U”. U tubes as well as straight tubes are significant in their own way and are used for various reasons and industrial applications. Choosing whichever is needed usually depends but they both are most likely to come in handy. Recognizing these different kinds of this bundle is exceptionally easy as the straight ones are rather plain and quite in symmetry whereas the U tubes are literally in the shape of a U – which is very easy to spot. The more commonly used type of tubes is the U ones, since they are more easily available and beneficial in comparison with the straight ones.

Shell and Tube Heat Exchanger Experiment

Introduction

The process of heat exchange between two fluids which are at different temperatures and flow rates occurs in many engineering applications. Several types of heat exchangers have been widely used in the industry. Shell-and-Tube heat exchangers are among the common types of heat exchangers.  A basic schematic for a single pass shell-and-tube heat exchanger is shown in Figure 1.  The stream to be cooled enters the tube side and is distributed amongst the tubes shown with red arrows.  

The stream that cools the liquid is shown in blue enters on the shell-side and flows perpendicular to the tube bundle for maximum heat transfer.  The shell-side flow passes around baffles placed around the tube bundle in order to increase both the residence time of the fluid around the tube bundle as well as to promote turbulence in order to maximize the efficiency of the heat exchanger. 

Heat exchangers are typically classified according to flow arrangement. In the parallel-flow heat exchanger, the hot and cold fluids enter at the same end, flow in the same direction, and leave at the same end. In the counter-flow arrangement, the hot and cold fluids enter the heat exchanger at different ends and flow in opposite directions. Each fluid arrangement leads to different heat rates and the calculations are different accordingly [1].

    

 

Figure 2 illustrates the Heat Exchanger experiment apparatus.  Based on long-term setup of the apparatus, the hot flow passes through the tube and the cold flow passes through the shell. Different configuration of valves can result in parallel and counter flows.  The hot and cold flow rates are measured by two flow meters, located along the incoming flows.

In order to measure the temperature of fluids and heat transfer surfaces, ten thermocouples have been installed in this apparatus. The measured temperature of each thermocouple is shown on the readout when the selector switch points to the thermocouple number. The thermocouples are located in different positions to measure the temperatures according to Table 1.

Table1. Thermocouples

Thermocouple	Measured Temperature	Thermocouple	Measured Temprature
1	Tube Inlet	5	Shell Inlet
2	Tube-side heat transfer surface at 16” *	6	Shell-side heat transfer surface at 16” *
3	Tube-side heat transfer surface at 19” *	7	Shell-side heat transfer surface at 19” *
