SCHULZ ADS 50 Refrigerated Air Dryer
If water is showing up at your tools, paint guns, or pneumatic controls, you are dealing with the most common issue in air treatment for compressors and blowers: moisture. The SCHULZ ADS 50 is a non-cycling refrigerated compressed air dryer rated at 50 CFM @ 100 PSI and offered as a complete kit for 10HP and 15HP compressor installations at USD 1,552.28.
Quick verdict
Shops with matching compressor sizes and average air use inside that range should put the ADS 50 on the short list. It runs on 115V single-phase power, so many workshops can install it without a new three-phase feed. The non-cycling refrigerant circuit helps limit energy use, and the integrated controller watches operating temperature and dew point for you.
Who it suits
This dryer fits shops running spray guns, sandblasters, or CNC equipment that cannot tolerate moisture. It also suits buyers who want hands-off drainage: the controller manages the drain valve and condenser fan for automatic operation. The unit accepts input pressure up to 200 PSI, which gives it compatibility with a range of compressed air systems.
What stands out from the listed details
The electronic controller is the standout because it displays both operating temperature and dew point, which lets you catch drying problems before water reaches your equipment. The automatic drain valve and condenser fan take over the daily maintenance chores. The dryer is built in Italy, and the 115V single-phase power requirement makes it practical for shops without three-phase electrical service.
Meaningful trade-offs
Capacity is the main constraint. The dryer is sized for 50 CFM at 100 PSI, so it fits a 10HP or 15HP compressor only if your actual average flow stays at or below that number. If your peak demand regularly goes higher, you will need a larger dryer or a different air treatment setup. The power setup can also be a limitation in shops wired only for 230V or 460V. And the California Prop 65 warning indicates possible lead exposure, so wear gloves and wash hands after handling the unit during installation or service.
Bottom line
For a shop with a matching-size compressor and steady demand within the rated envelope, the SCHULZ ADS 50 provides hands-off refrigerated drying and a visible readout of drying performance. At USD 1,552.28, it solves the usual moisture problem without requiring three-phase power. If your air consumption stays within the rated envelope, this kit is a practical match.
