The Schulz ADS 20 Non‑Cycling Refrigerated Compressed Air Dryer is engineered to provide reliable moisture removal for compressed air systems using up to 5 HP compressors. Designed for consistent performance, it operates efficiently even in environments with elevated ambient and inlet temperatures.

With energy‑efficient sizing, the ADS 20 matches the compressor’s air displacement to help reduce power consumption. An integrated electronic controller with digital display shows temperature and dew point, controls the automatic drain valve via timer, and regulates the condenser fan through a temperature probe to maintain optimal operating conditions.

This unit features a high‑efficiency refrigeration compressor, a compact non‑cycling design, and a quick‑disconnect automatic drain valve that requires no special tools for maintenance. It operates on a standard 115V single‑phase power supply and uses environmentally friendly R134a refrigerant.

Factory 1‑Year Warranty Included.
