The purpose of an air compressor is to generate sufficient pressure for compressing the air for use across various applications. Depending on the applications, any potential impurity in the air can cause serious repercussions for the system.
One of the major issues that come up with air compressors more often is condensation. It hampers the quality of air and affects the air compressor adversely. Not just that, but condensation can also possibly corrode several parts of the compressor or might lead to vapor problems.
One of the best ways to prevent these discrepancies in air compressors is by using an air dryer. With the use of an air dryer, the compressor system will be free from moisture deposits, and the air quality will improve. It helps you overcome the condensation problem completely. Thus, this is how the air dryer works in a compressor!
But, with a great number of air dryer options out there in the market, it might be difficult for you to choose the best that can meet your needs. So, here’s a brief insight into some of the considerations for choosing the right air dryers in India for the compressor.
How Does An Air Compressor Dryer Work?
Air dryers are pretty much essential for air compressors. The usual functionality of air compressors produces a lot of water. There is a proper setup for draining this water, but the moisture is difficult to remove entirely from the compression system. As a result, condensation, rusting, freezing of other outdoor lines, piping corrosion, and other such problems might occur.
Therefore, air dryers are used to keep the compressors free from moisture content. The compressed air dryer is equipment meant for separating moisture and water vapor from the industrial systems that process air. In a typical setup, the compressor draws humid air and compresses it. It will then raise the air temperature and cool down the water vapor, eliminating it from the unit.
Different types of air compressors work with varying principles, but the end purpose remains the same.
Different Types of Air Dryers
Before you get along with the consideration factors, develop an understanding of the varying types of air dryers:.
1. Refrigerated Air Dryer
The refrigerated version is one of the most popular compressor dryer types, being used across various applications. It cools down the air to a very minimal temperature, which enables the moisture within to condense back to the liquid form. When the water is dried, dry air can pass through the system to its application point.
2. Desiccant Air Dryer
In applications where refrigerated dryers aren’t compatible, desiccant air dryers are considered feasible alternatives. A porous hygroscopic media, such as activated alumina, silica gel, or molecular sieve, is used to absorb moisture from moving air and dry it off to protect the compressor.
3. Deliquescent Air Dryer
The deliquescent air dryers have pressure vessels with salt tablets within. When the salt dissolves, it tends to absorb the water vapor from the air. Thus, you will simply be able to run the compressed air through this deliquescent air dryer, and the salt will be pulled out of all moisture content from it.
4. Membrane Air Dryer
This air dryer has the capability of utilizing various membranes, consisting of microtubules, for filtering moisture. The purpose of these microtubules is to retain the water while a stream of air is allowed to flow through the system to the point of application or a collection unit. It is used for food processing, gas separation, and dehumidification applications.
Factors to Consider While Choosing the Perfect Air Dryer
When you are making efforts to pick the right air dryer for your compressor, you are craving for your system’s efficiency. Moreover, a small investment in an air dryer will help you reduce downtime and increase productivity. So, while you are considering the purchase, here are some factors for you to take note of:
1) Rate of Flow
When choosing an air dryer, you should look out for the maximum capacity of the air compression ratings of your system. The capacity of the system will be determined as Standard Cubic Feet Per Minute (SCFM) at 100 PSIG. You can also calculate an approximation by multiplying the air compression HP by 4.
2) Operating Pressure
Determining the best air dryer for compressors is directly dependent upon the maximum & minimum operating pressure of the system. The compressor dryers are rated mostly at 100 PSIG, and for every increase, the capacity is hence reduced. As the pressure increases, the moisture load will decrease. Thus, the strain on the compression system will also be reduced.
3) Ambient Temperature
You should determine the operating ambient temperature at both maximum and minimum levels. It will help you choose either a low-temperature or a high-temperature air dryer. If the ambient temperature of your system goes beyond 100 degrees Fahrenheit, choose high-temperature air dryers.
4) Dew Point & Air Inlet Temperature
The air inlet temperature of your system is also worth considering when choosing an air dryer. Following this, you should then determine the requirement of the dew point in an air compressor. Choose an air dryer that can work feasibly at a dew point below the lowest ambient operating temperature. The dew point meter for the air dryer is calculated by lowering the lowest air temperature by 20 degrees.
5) Environment and Application
One of the most crucial factors for choosing the right air dryer for your compressor is its application. Most compressor applications can use a refrigerated type of dryer, which provides air with around 10% or 20% humidity. On the other hand, desiccant dryers are capable of producing relative humidity of less than 0.5% for outlet air and are meant for high-end applications.
Beyond these factors, you can also count on considering the location, indoor vs. outdoor placement, or weather as your considerations. You can take the help of our experts in order to determine what type of air dryer would suit the best for your air compressor system or applications.
