Description
Stop Moisture From Reaching Your Tools and Air Lines — Schulz ADS 100 Refrigerated Air Dryer (100 CFM)
Compressed air leaves the tank saturated with water vapor. As it cools downstream, that vapor condenses into liquid that rusts piping, fouls air tools, ruins paint and powder finishes, and freezes control lines. The Schulz ADS 100 is a non-cycling refrigerated air dryer that chills 100 SCFM of compressed air to a stable 41°F dew point, dropping the water out before it ever reaches your equipment. It is sized to match the output of industrial systems (~10-25 hp), so you dry your air without oversizing or wasting energy. If you are unsure whether the ADS 100 matches your compressor, call or text CET at 586-210-0555 before ordering — we will confirm the right capacity for your system.
✓ Non-cycling refrigerated design — stable, reliable dew point • ✓ 100 SCFM at 100 psig • ✓ DMC35 digital controller • ✓ Automatic timed condensate drain • ✓ R134a refrigerant — high efficiency

Common Questions
Frequently Asked Questions
- What does a refrigerated air dryer actually do?
- It chills the compressed air to condense out water vapor, then reheats the now-dry air and drains the liquid away. The result is air at a stable 41°F pressure dew point — dry enough to protect tools, piping, pneumatic controls, and finishing equipment from rust and water spotting.
- What does “non-cycling” mean?
- A non-cycling dryer runs its refrigeration circuit continuously and uses a hot-gas bypass valve to hold a constant dew point. That keeps the outlet dew point steady regardless of load swings, with no warm-up delay and none of the wet-air spikes that cycling (thermal-mass) dryers can produce when demand jumps.
- How do I size the ADS 100 to my compressor?
- Size the dryer above your compressor’s actual SCFM delivery, then correct for your real operating pressure, inlet air temperature, and ambient temperature — hotter or lower-pressure air needs a larger dryer. The ADS 100 is rated at 100 SCFM under standard conditions. Call or text 586-210-0555 with your compressor and shop conditions and CET will confirm the correct model.
- Do I still need filters with a refrigerated dryer?
- Yes. A coalescing pre-filter protects the dryer from oil and bulk liquid, and a particulate after-filter is recommended for finishing and instrument air. CET can spec the matching filtration — call or text 586-210-0555.
- What maintenance does it need?
- Keep the condenser clean and verify the automatic drain is discharging. The removable panels give tool-free access to internal components, and the DMC35 controller flags service conditions on its display.
