Description
Dry Hot Compressed Air Straight Off the Compressor — Schulz SMH-30-UP High-Temperature Air Dryer (30 CFM)
Standard refrigerated dryers choke on hot air. Discharge straight off a compressor can reach 180–200°F, far above what a conventional dryer can handle — so shops are forced to add a separate aftercooler and moisture separator just to protect the dryer. The Schulz SMH-30-UP high-temperature dryer has that aftercooler built in. It accepts inlet air up to 194°F (90°C) and dries 30 SCFM in a single package — no separate aftercooler, no extra separator, less to install and maintain, and less floor space. If you are matching this to a specific compressor and duty cycle, call or text CET at 586-210-0555 before ordering and we will confirm the right model.

Common Questions
Frequently Asked Questions
- Why do I need a high-temperature dryer instead of a standard one?
- A standard refrigerated dryer is rated for inlet air around 100°F. Air coming straight off a compressor is far hotter — often 180–200°F — which overloads a standard dryer and ruins its dew point. The SMH-30-UP is built to accept up to 194°F directly, with a built-in aftercooler doing the first stage of cooling.
- Does this replace a separate aftercooler and moisture separator?
- Yes. The aftercooler circuit and condensate separation are built in, so you do not need a standalone aftercooler or separator ahead of it. That means less equipment to buy, install, and maintain, and less floor space used.
- How do I size the SMH-30-UP to my compressor?
- Start from your compressor’s SCFM output, then correct for your actual inlet air temperature, pressure, ambient temperature, and required dew point — hotter inlet air and higher dew points change the usable capacity. The SMH-30-UP is rated at 30 SCFM under nominal conditions. Call or text 586-210-0555 and CET will confirm the model for your conditions.
- What dew point does it deliver?
- Nominal capacity is rated at a 50°F (10°C) pressure dew point. Capacity increases at higher dew points and decreases at lower ones — the DMC35 controller displays the live dew point during operation.
- What maintenance does it need?
- Keep the condenser clean, confirm the automatic drain is discharging, and check the dew-point reading. Refrigeration-circuit service must be done by a certified refrigeration technician.
