We can all agree that desiccant dryers are important for maintaining clean, desiccant compressed air in a range of industrial applications. However, without regular maintenance, these systems may endure wear and tear that is not immediately apparent.
By the time a problem develops, the water, oil, or desiccant dryer may have gone downstream, damaging sensitive equipment or contaminating the finished product. Routine maintenance not only extends the life of your desiccant air dryer, but also ensures top performance, lowers energy usage, and eliminates the need for costly emergency repairs or rental equipment.
How can you ensure that your desiccant air dryer is operating at top performance all the time? Read on to learn more!
Impurities such as compressor oil, condensed water, and dust can damage the desiccant band components in your dryer, hence the pre-filter is important. Compressor oil has the potential to start a fire in heat-regenerated dryers. A differential pressure gauge or indication can alert you when it is time to replace the filter components, which are normally done every 6 to 12 months.
To prevent contaminants from reaching the desiccant, regular inspections and time-based filter element changes are important. You can hire a professional to handle the maintenance of your desiccant air dryer.
Control valves used in regenerative desiccant dryers include intake switching valves, purge exhaust valves, check valves, and solenoids. Every year, these valves should be cleaned and inspected, and any worn or damaged parts replaced. Most valves may be repaired with repair kits, which are a cheap way to keep them running properly.
You should also check the purge settings, as these are important to the proper operation of your desiccant air dryer. The purge adjustment valve or purge pressure should be checked on a regular basis to ensure that it is appropriately set. To establish the correct settings, consult your dryer’s instruction guide. After all, using incorrect purge settings might waste energy and degrade dryer performance.
Regular maintenance will extend the life of your desiccant air dryer. Remember that regular maintenance on your desiccant air dryer benefits both your equipment and the environment.
By ensuring that your desiccant air dryer operates efficiently, you may save energy and lower your carbon footprint. Properly maintained dryers also contribute to waste reduction by lowering the frequency of desiccant changes and the need for an emergency.
