Altec HRL-250-1 Heatless Desiccant Air Dryer

250 SCFM | -40°F Dew Point | Made in the USA

Moisture is silent, invisible, and wildly expensive. It corrodes tools, ruins finishes, contaminates product, and shortens equipment life. The Altec HRL-250-1 eliminates it with industrial authority.

Designed and manufactured in the United States, this heatless desiccant dryer delivers 250 SCFM at a -40°F pressure dew point, meeting ISO 8573.1 air quality standards. Built for continuous-duty industrial service, the HRL-250-1 is engineered to protect mission-critical compressed air systems.

Available with or without a 3-Valve Bypass, you can configure the unit based on your plant’s redundancy and maintenance strategy.

Configuration Options

Standard Model (No Bypass)

Ideal for systems where:

• A backup dryer is already installed

• Maintenance windows are scheduled

• Budget optimization is a priority

3-Valve Bypass Package

Recommended for facilities where uptime is critical.

Benefits include:

• Isolate the dryer without shutting down the plant air

• Perform maintenance without stopping production

• Reduce costly downtime events

In high-production environments, the bypass can pay for itself the first time service is required.

Ideal Applications

• CNC & Precision Machining

• Manufacturing & Fabrication

• Powder Coating & Finishing

• Automotive & Paint Systems

• Food Processing & Packaging

• Any facility requiring consistent ISO-quality dry air

If moisture equals defects in your operation, this dryer belongs in your system.
