Refrigerated Air Dryers

Moisture, either liquid or vapor, is present in compressed air as it exits the compressor system. If this moisture is not properly removed, your compressed air system can lose efficiency and require dramatically increased maintenance, which can result in costly downtime.The majority of pneumatic instruments and processes can not tolerate hot compressed air, compressors are normally supplied with after-coolers and moisture separators. After-coolers are heat exchangers that utilize either water or ambient air to cool the compressed air. As the water and lubricant vapors within the compressed air cool, a significant amount condenses into liquid. An after-cooler discharging compressed air at 100F passes 67 gallons of water per 1,000 scfm per 24 hours.To avoid these problems, compressed air systems have purification devices available to remove the water vapor and other contaminants. The proper selection of these devices is critical as pneumatic applications and compressed air systems become increasingly sophisticated.
