Chicago Pneumatic CPD Portable Desiccant Dryers

Chicago Pneumatic CPD Portable Desiccant Dryer Series

When your jobsite, rental fleet, or industrial process depends on dry compressed air, moisture is not a small problem. It is a direct threat to uptime, downstream equipment, and finished results. The Chicago Pneumatic CPD Portable Desiccant Dryer Series is built to remove that risk by delivering dependable, field-ready dry air in demanding environments. Designed for rental, chemical, oil and gas, and mining applications, the CPD 850, CPD 1200, and CPD 1700 give contractors and industrial operators a portable air treatment solution built for real-world conditions, not sheltered shop floors.

These dryers are engineered to maintain a steady pressure dew point of -40°C/-40°F, helping protect downstream tools, piping, instrumentation, and process equipment from moisture-related corrosion, freezing, contamination, and premature wear. Chicago Pneumatic pairs that drying performance with a practical portable package that is compact, easy to move, and simple to set up in the field. That combination makes the CPD series a strong choice for pipeline jobs, offshore work, exploration drilling, shipyard sandblasting, and other demanding temporary air applications.

Why the CPD Series stands out

The CPD Portable Desiccant Dryer Series is built around a twin-tower desiccant drying design. One tower dries the compressed air while the other regenerates, allowing continuous delivery of dry air. The dryers use activated alumina desiccant and wide vessels to keep air speed low, increase contact time, and support longer desiccant life. In practical terms, that means more stable drying performance and better protection when conditions are hot, humid, dusty, or simply rough on equipment.

Chicago Pneumatic also focused heavily on ease of operation. These dryers feature 100% pneumatic controls, which means no external power is required. That matters on remote jobsites and temporary installations where simplicity and reliability are everything. Just set the unit in place, connect it, and get to work.

Key features and benefits

• Reliable -40°C/-40°F pressure dew point performance
• Activated alumina desiccant for dependable moisture removal
• Up to 20% extra desiccant for stronger performance in harsh conditions
• 100% pneumatic controls with no external power required
• Built-in water separator plus inlet and outlet filtration for cleaner air
• Durable stainless-steel butterfly valves for long service life
• Advanced silencers to reduce noise and improve purge efficiency
• Galvanized piping with flanged design for simpler maintenance and low pressure drop
• Heavy-duty crash frame with lifting lugs and forklift slots on all sides
• Compact footprint for easier transport, storage, and deployment

Another major advantage of the CPD series is how much protection is built into the package. The filtration system includes an inlet water separator to remove liquid water before it reaches the drying towers, a high-quality oil coalescing inlet filter to block oil particles and dust, and an outlet air filter to help stop desiccant particles from moving downstream. That layered protection matters because dry air alone is not enough if contaminants are still moving through the system. Clean, dry air helps reduce wear on tools, supports more consistent production, and lowers the risk of avoidable shutdowns.

The user-friendly frame design is another major selling point. Chicago Pneumatic built these dryers with a stackable crash frame that saves storage space and helps simplify transportation. The plug-in and plug-out design minimizes on-site installation time, and the low center of gravity helps improve stability once the dryer is positioned. High-quality exterior paint provides added resistance against harsh weather and rough handling, making the CPD series a strong fit for field service, rental operations, and industrial sites that demand durable equipment.

Available models in the CPD Portable Desiccant Dryer Series

1. CPD 850
   Delivers 880 cfm at 7 bar / 100 psi, with flow increasing to 1,430 cfm at 14 bar / 200 psi.
2. CPD 1200
   Delivers 1,200 cfm at 7 bar / 100 psi, with flow increasing to 1,944 cfm at 14 bar / 200 psi.
3. CPD 1700
