Hotter Isn’t Always Better: High-Temperature Air Dryers

High-Temperature Air Dryers

Hotter is Better, Right?

With global temperatures on the rise high-temperature air dryers are becoming more popular, the average ambient air temperature is going to rise as well. As air temperature increases, additional pressure is placed on your air system while humidity adds extra moisture to the air. When these two factors work in cohesion against your system, it only means bad news down the line. You may need to look and see if you need a High-Temperature Air Dryer. 

Additional pressure and moisture are less than ideal for a system that is finely tuned. These small changes can have large effects on your compressed air system and its health. Alongside a decrease in overall health, these problems can cause a decrease in performance as well. 

As temperatures and humidity rise, extra strain on your compressed air system is a given; however that does not mean you should just accept it as part of your operating parameters during the summer time. It is possible to combat these conditions with the right equipment, like a High-Temperature Refrigerant Dryer.

The individual dryer that you have in place may not be the best fit for your current system. With a change in equipment you will be able to capitalize on energy savings and output the highest quality air. 

 

 

Moisture in your airlines is a problem waiting to happen, as it is known for causing internal problems ranging from unplanned downtime, component failure and growth of unwanted bacteria. This can be detrimental to your system and your end product, both of which are less than ideal, but can be handled by a High-Temperature Air Dryer.

With every compressed air system, you need to be aware of your system’s individual factors to find the best fit. Is it generally hot where you live, how humid does it get, how much energy are you using, and your average run time are all questions that will dictate what type of dryer you need.

 

Why Care About High-Temperature Air Dryers

To keep it simple: higher temperatures means your air is less dense and you will have less air being taken in by the system. Less air being brought in means less air being turned into compressed air. This limits the output of your system and throws off the alignment based on your base conditions.

What do we consider base conditions? We keep it quite simple with the rule of Three 100s:

  • 100°F Inlet Air Temperature
  • 100°F Ambient Temperature
  • 100 PSIG Inlet Air Pressure

By standardizing these variables it allows you to compare the efficiency of different machines in similar environments. This helps differentiate between the physical differences between a High-Temperature Dryer and a normal refrigerated dryer.

Depending on your system, your dewpoint can vary depending on a multitude of factors, but your dryer will have a rated dewpoint when operating at standard conditions. Your dewpoint is the temperature at which moisture vapors located in the air condense into water. You ideally want your dewpoint to be as low as possible to prevent condensation in your air tools.

 

A Higher Degree of Moisture Management

The degree of filtration that is achieved by your compressed air system is dependent on the quality and style of filtration system that you have in place. Different combinations of dryers and filters can achieve different dew points.

There are multiple ways you can dry compressed air, but this isn’t about all of the ways you can do it. To give you an idea here are some of the most common means:

  • Over Compression  
  • Aftercoolers 
  • Refrigerant dryers  
  • Membrane dryers 
  • Absorption and adsorption drying

But High-Temperature Air Dryers exist in a league of their own outside the traditional methods of air cooling. These dryers are built to go where other dryers cannot. Most dryers are rated for dewpoints around 40⁰F with air that is typically at or below the rated temperature of 100⁰F. 

Meanwhile your standard High-Temperature Air Dryer will be able to take air up to 180⁰F and bring it down to air with a dewpoint of 50⁰F. That means it would have to be roughly 150⁰F in the compressor room for these dryers to get overwhelmed, and if your room is that hot you may be experiencing bigger issues.

Designed to be able to handle extremely high temperatures without letting moisture downstream, high-temperature air dryers are the perfect match for compressors that lack aftercoolers. The perfect fit for when nothing else works. High-Temperature Air Dryers will handle the heat and keep your system running smoothly.

 

Additional Considerations

Remember This With High-Temperature Air Dryers

Based on the nature of air compression, air compressors will create a lot of heat on their own. This air is going to affect the rest of the system with this excess heat as it is brought downstream and going to bring all the problems with it.

With this heat is going to come more moisture and more moisture means more problems now and later. These problems can cause unnecessary downtime or potentially ruin your new equipment. No matter where it goes, your equipment is going to bear the consequences of that heat. 

One of the main causes of excess moisture in your system is increases in temperature.. With increased temperature comes increased humidity and this means more moisture in the air. More moisture means more build-up and adds pressure to your filtration and drainage systems.

Higher temperatures result in your air being less dense and less dense air means a lower total volume of air existing in a given space. The increase in heat causes an increase in energy which keeps the molecules farther apart from each other thus making it take up more space as a whole and having less in a specific area.

The main benefit to your High-Temperature Air Dryer is the ability to reduce extremely hot air to a dewpoint of 50⁰F. And just so you don’t forget the dewpoint is the temperature at which the moisture in the air turns into condensate.

 

Before You Buy

Make sure you do a quick rundown of your needs before you make an investment in a High-Temperature Air Dryer. If your compressor does not have an aftercooler or you operate in an extremely hot environment, then this is the compressor for you.

With a wide selection of the best high-temperature air dryers available, you have come to the right place. With the best brands in compressed air moisture removal, you won’t find higher quality products at a better price. With name brands like Atlas Copco, Pneumatech, and Nano, there is no bad choice.
