We all agree that desiccant dryers are important for maintaining clean, dry, compressed air in many industrial applications. But without regular maintenance, these systems can suffer from wear and tear that may not be immediately noticeable.
By the time a failure occurs, water, oil, or desiccant dryer may have already migrated downstream, potentially causing damage to sensitive equipment or contaminating products. Routine maintenance not only extends the lifespan of your desiccant air dryer but also allows for optimal performance, minimizes energy consumption, and prevents the need for costly emergency repairs or rental equipment.
So, how do you ensure your desiccant air dryer is in top shape at all times? Read on below to uncover more!
Start with the Filters
The pre-filter is important for protecting your dryer’s desiccant band components from contaminants like compressor oil, condensed water, and particulates. In heat-regenerated dryers, compressors oil can even pose a fire hazard. A differential pressure gauge or indicator shows when it is time to change the filter elements, typically every 6 to 12 months.
In this regard, regular inspections and timely replacements of filter elements are important for preventing contaminants from reaching the desiccant. You can have a pro handle this maintenance aspect of your desiccant air dryer.
Inspect and Maintain Control Valves
Regenerative desiccant dryers count on various control valves, including inlet switching valves, purge exhaust valves, check valves, and solenoid valves. These valves should be cleaned and inspected annually, with worn or damaged parts replaced as need be. Repair kits are available for most valves, offering a cost-effective way to maintain their performance.
You should also focus on the purge settings since they’re essential to the smooth operation of your desiccant air dryer. The purge adjusting valve or purge pressure should be checked periodically to ensure it’s set correctly. Ensure you refer to you dryer’s manual for the right settings. After all, incorrect purge settings can lead to wasted energy or diminished dryer performance.
With proper maintenance, your desiccant air dryer can serve you for years. Remember, regular maintenance of your desiccant air dryer isn’t just good for your equipment, it is also beneficial for the environment,
By making sure your desiccant air dryer operates efficiently, you can reduce energy consumption, which lowers your carbon footprint. Properly maintained dryers also minimize waste, as they reduce the frequency of desiccant replacement and the need for emergency.
