Compressed air dryers reduce the moisture content of ambient air, so they're an important part of many manufacturing environments. Of course, there's more than one type of compressed air dryer, but most people come down to refrigerated air dryers vs. desiccant air dryers.
Here's the difference between them:
While it's true that refrigerated air dryers and desiccant air dryers each have their own pros and cons, most users will find themselves better off with a refrigerated version. Here are just a few reasons why.
The main reason refrigerated air dryers are the most popular type is that they are relatively inexpensive. You'll first notice that when you pick yours out – refrigerated air dryers come at a much lower price than desiccant dryers, and they're also less expensive to set up. Perhaps more importantly, refrigerated dryers are inexpensive to operate. In contrast, desiccant dryers frequently suffer air loss through purges and pressure drops, so they aren't as efficient.
One of the main issues with desiccant air dryers is that they require more maintenance work. This is another factor that pushes up ongoing costs, but the associated inconvenience is often a greater concern. The main problem is that airborne oil particulates will degrade desiccant agents. Filters must be fitted and then replaced regularly to ensure your pricy, new equipment isn't ruined. Refrigerated dryers are completely resistant to airborne oil particles.
One of the nice things about working around a refrigerated air dryer is that the air never gets too dry. The dryer will remove most of the air moisture to keep things safe and hygienic, but the air around you will still have enough water vapor for comfort. Work around a desiccant dryer and you'll often feel the air getting a little too low on moisture.
Lower Pressure Drop
Pressure drops are lower with desiccant air dryers, and that can be a problem since excessive pressure drops can lead to poor performance and higher-than-average energy consumption. Refrigerated dryers don't have the same pressure problems.

To get the right plastic products, your business needs to find the right manufacturer and supplier. If you've never done this before, then choosing the right company to work with can be a headache. I'm Mike. I worked in industrial procurement before I retired and I set up this blog to help people get the information they need when they're working with plastics companies. My blogs will hopefully help you understand more about plastics manufacturing and the related stuff that's important to any business now, like recyclability and green production techniques. Hope it's interesting reading and makes it easier for you to produce the products you need!
