What are the main differences between refrigerated and desiccant air dryers? Refrigerated Air Dryers A refrigerated air dryer chills the compressed air to 33 – 40 degrees Fahrenheit at which water vapor is condensed into a liquid and is then expelled from the system via a water-trap and automatic drain. The cool dry air then is typically re-heated to around room temperature before exiting the dryer and going to your production lines. This helps reduce condensation on the compressed air piping. There are two types of refrigerated dryers; cycling and non-cycling. Non-Cycling Air Dryers: Non-Cycling air dryers allow the refrigeration circuit… Read more »

Excess moisture in your compressed air system can cause problems both within the system itself and for the applications that utilize it. Appropriate maintenance and the use of air dryers can remove moisture from your air and extend the life of your system. What Causes Moisture in Compressed Air? Moisture is an inevitable byproduct of compressed air. All air contains a certain amount of water vapor. The volume of water held by the air varies with temperature and pressure; the higher the temperature, the more water air is able to hold. That’s why humidity tends to be higher in warmer… Read more »
Air leaks are very common in compressed air systems. The key is to know how to detect and fix them as the cost of even a tiny leak adds up to a large expense if left unattended. How common are compressed air leaks? Compressed air leaks are widespread in all applications. Not only are they common, but they are time-consuming to find and fix. In the average manufacturing operation, 20-30% of the total energy consumption is compressed air. On average, 30% of that expense is due to compressed air leakage.

Have you ever dusted yourself off with compressed air and ended up getting power washed with water instead?! Where did that water come from and does it belong there? As we learned in science class, the air we breathe contains water in a gaseous state. The compressed air industry expresses the amount of water in a system by dewpoint and relative humidity. The warmer the air, the more water the compressed air can hold. This is why we see so much more water in our compressed air on a hot summer day after it has rained. When we compress the… Read more »
There are 2 key aspects to sizing your piping correctly: max system CFM requirements and minimum required operating pressure. Max CFM A study needs to be completed to determine what the max demand in the system (in CFM) is going to be. This needs to be a worst case scenario, with even momentary uses being considered Momentary uses of compressed air are considered any usage of your air for a period of time that is less than a minute. Examples of these momentary uses are; dust collector blow down valves, large air cylinder/ ram actuation, sometimes diaphragm pumps, and… Read more »

Is Your Air Compressor Overheating? Do you experience excessive downtime due to your air compressors shutting down on high temperature? Does downtime cost your company money? Here are a few reasons your compressor may be shutting down with high temperature alarms; Dirty or clogged coolers (air/oil) Low on oil Clogged Oil Filter(‘s) and, or Air/Oil Separator(‘s) Faulty Thermal Valve Faulty HAT(High Airend Temperature) sensor Excessive ambient temperatures If compressor is ventilated, ducting may be undersized or need a booster fan Compressor oil may be varnishing causing excessive friction in the pump
This week’s discussion addresses what seems to be an unknown to most users of compressed air. Many calls come in from customers who say their compressor system no longer keeps up with plant demand. Of course, this could be due to many factors such as added production equipment, air leaks in the equipment and/or distribution piping, or the need of maintenance to the air compressor itself. To troubleshoot your plant pressure issues, we recommend beginning with the source of your compressed air. Is the compressor delivering its rated Actual Cubic Feet per Minute (ACFM)? ACFM is the air delivery rating… Read more »

If you are shopping for a new air compressor, you might be overwhelmed by the different types and options. The first and most important choice you will make is whether to buy a rotary or a reciprocating compressor. Many people don’t know the difference between them, so let’s look at these two types. Reciprocating air compressors compress the air with pistons that move up and down inside the cylinders. Rotary screw air compressors have two rotors that turn in opposite directions. The air is trapped between thus causing compression to occur. Their manner of compressing air is not the only… Read more »
