What our Experts Think
-
Reliable compressed‑air moisture control: The Schulz ADS‑20 Air Dryer Non‑Cycling – ADS‑20‑UP delivers 20 CFM of dried air from your compressor, reducing water and condensate that can harm pneumatic tools, paint systems, and production equipment.
-
Non‑cycling refrigerated design: This refrigerated, non‑cycling dryer runs continuously for stable dew‑point removal throughout extended use — ideal for systems that operate at steady loads without frequent cycling.
-
Smart electronic control: Integrated digital temperature and dew‑point display, along with automatic drain and condenser fan control via timer and probe, makes operation simple and efficient.
-
Energy‑efficient sizing: Matched to compressors in the ~20 CFM range, the unit avoids oversizing and reduces unnecessary energy use while maintaining reliable performance.
-
Compact, service‑friendly build: Removable access panels and a quick‑disconnect automatic drain valve simplify routine maintenance without special tools.
-
Strong pressure & durable design: Rated up to 232 PSI maximum inlet pressure with a ½″ NPT‑F connection, it integrates easily into typical workshop systems and stands up to demanding conditions.
Q&A
Q: What is the Schulz ADS‑20 air dryer designed for?
A: It’s a non‑cycling refrigerated compressed air dryer that removes moisture from compressed air up to 20 CFM, protecting tools and pneumatic systems from corrosion, rust, and water damage.
Q: What power and connection requirements does it have?
A: It runs on 115 V single‑phase power and uses 1/2″ NPT‑F inlet/outlet connections, fitting standard small‑to‑medium compressor setups.
Q: What pressure range does the ADS‑20 support?
A: Designed for up to 100 PSI nominal pressure with a maximum operating pressure of 232 PSI, suitable for most shop and industrial air systems.
Q: How does the moisture removal system work?
A: The refrigeration system cools compressed air to condense and collect moisture; an electronic controller displays temperature and dew point and manages the automatic drain and condenser fan for efficient operation.
Q: What are the key convenience and build features?
A: It has removable access panels for easy maintenance, a quick‑disconnect automatic drain valve (no tools needed), environmentally friendly R134a refrigerant, and a compact, lightweight footprint (~55 lbs) for flexible placement.
Q: Where is the ADS‑20 best suited?
A: Ideal for compressor systems up to 20 CFM in workshops, garages, and industrial facilities where consistent dry air improves tool life and performance.
Maintenance Tips
-
Disconnect Power Before Maintenance: Always turn off and unplug the unit before cleaning or servicing.
-
Drain Moisture Regularly: Even non-cycling dryers can accumulate condensate; check and drain the tank and moisture trap as needed.
-
Inspect Air Connections & Hoses: Ensure fittings, hoses, and clamps are secure and free of leaks or damage.
-
Clean Exterior & Cooling Fins: Remove dust and debris from the dryer’s housing and fins to maintain airflow and cooling efficiency.
-
Check Pressure Settings: Periodically verify that the pressure gauge and relief valves operate correctly within the rated 232 PSI.
-
Inspect Electrical Components: Confirm that wiring, plugs, and switches are secure and undamaged.
-
Protect From Moisture & Corrosion: Store in a dry, ventilated area; wipe exposed metal surfaces to prevent rust.
