5 Best Maintenance Software Tools for Industrial Resin Dryers & Hoppers (2026 Review)

"We scrapped the whole shift of parts because they failed the impact test. The resin was wet."

Industrial Dryers (Desiccant, Compressed Air, Vacuum) are critical for processing hygroscopic materials like Nylon, PET, and PC.

They are often neglected. They sit in the mezzanine, humming away, until quality crashes.

Legacy maintenance (changing desiccant "yearly") is risky. If a hose leaks or a valve sticks, the dew point rises instantly.

In 2026, Dryer Maintenance Software is proactive. It monitors the Dew Point. It tracks the Regeneration Cycles. It ensures the Process Temperature is stable.

Here are the 5 best tools to keep your resin dry and your parts strong.

The Comparison Matrix (2026)

1. Fabrico: The "Quality-Link" Platform

Verdict: The best choice for factories with a Mixed Fleet (Conair, Novatec, Moretto) that need to link Dryer Performance to Production Quality.

Fabrico treats the dryer as a critical quality node. We connect to the dryer controller or add external Dew Point sensors.

Why It Wins on Dryers:

• Dew Point Alerts: Fabrico monitors the dew point continuously. If it rises above -30°F, it triggers an "Inspect Bed Switching Valve" task immediately. This prevents wet resin from entering the screw.

• Filter Change Optimization: Instead of changing filters on a calendar, Fabrico monitors the pressure drop. "Replace Return Air Filter" is triggered only when airflow is restricted, saving money and protecting the blower.

• Unified Dashboard: See the dryer status right next to the Injection Molding Machine status. If the machine stops, check if the dryer alarmed first.

Best For: Injection Molding, Extrusion, and PET Bottle manufacturing.

2. Conair (SmartServices): The "OEM" Standard

Verdict: The industry leader if your auxiliary equipment is primarily Conair.

Conair’s platform connects all their auxiliaries (Dryers, Blenders, Chillers) into one web view.

Pros:

• Deep Integration: It controls the dryer logic. It can automatically lower the temperature ("Setback") if the molding machine stops, saving energy and preventing material degradation.

• Alarm Intelligence: Decodes complex dryer alarms (e.g., "Dew Point Sensor Open Loop") into plain English.

Cons:

• Brand Focused: Best for Conair. Harder to integrate your legacy Dri-Air or Universal Dynamics units.

• Siloed: It manages the auxiliaries, but not the molding machine maintenance.

Best For: Conair-heavy plastics plants.

3. Maguire: The "Batch" Specialist

Verdict: Strong for monitoring Vacuum Dryers (which Maguire pioneered).

Maguire dryers work differently (Vacuum vs. Desiccant). Their software tracks the vacuum cycles.

Pros:

• Vacuum Tracking: Monitors the vacuum level to ensure moisture is actually boiling off.

• Simplicity: Very focused, easy-to-understand controller interface.

Cons:

• Data Access: Often requires being near the controller to see the deep history, unless networked via their specific protocol.

Best For: Plants using Vacuum Drying technology.

4. Wittmann (4.0): The "Workcell" Integrator

Verdict: Essential if you run Wittmann Battenfeld workcells (Robot + Machine + Dryer).

Wittmann 4.0 integrates the dryer directly into the Injection Molding Machine screen.

Pros:

• Single Screen: The operator controls the dryer from the molding machine HMI.

• Recipe Sync: Loading a mold recipe automatically sets the correct drying temperature.

Cons:

• Ecosystem: You need to buy into the whole Wittmann ecosystem to get the full benefit.

Best For: Integrated Wittmann cells.

5. MaintainX: The "Cleanout" Log

Verdict: The simplest way to manage the manual Hopper Cleaning logs during material changes.

Material contamination is a huge risk. MaintainX digitizes the cleaning verification.

Pros:

• Photo Verification: Operators snap a photo of the empty, vacuumed hopper before loading the new resin.

• Simple: No PLCs needed.

Cons:

• Manual: It doesn't monitor dew point. It relies on the operator to verify the dryer is working.

Best For: Job shops with frequent material changes.

Conclusion: Dry Resin = Good Parts

Don't let moisture kill your quality.

• If you have Conair, use SmartServices.

• If you have Wittmann, use Wittmann 4.0.

• If you need a Unified Platform that monitors Dew Point, tracks Filter Life, and enforces Cleaning Logs across a mixed fleet, Fabrico is the 2026 solution.
