Enhancing Industrial Efficiency with Powerex’s TDD Industrial Air Treatment Skid
In any industrial operation, compressed air is a vital utility—second only to electricity in importance. But raw compressed air straight from a compressor is often hot, wet, and contaminated with oil, particulates, and moisture. For industries that rely on high-quality air to ensure product integrity and protect sensitive equipment, this poses a major challenge.
That’s why Powerex, a pioneer in oil-free and clean air systems, developed the TDD Industrial Air Treatment Skid. This all-in-one solution delivers clean, dry, and consistent compressed air, designed to meet the exacting standards of industrial applications ranging from food packaging and pharmaceuticals to automated assembly lines and pneumatic controls.
In this article, we’ll explore the TDD Air Treatment Skid in depth—how it works, its benefits, key technical specifications, and how it can elevate the reliability, performance, and efficiency of your facility’s compressed air system.

Why Compressed Air Treatment Matters
Compressed air, if untreated, is a liability rather than an asset. It contains:
Water vapor that condenses into damaging moisture
Oil aerosols that contaminate downstream equipment
Solid particulates from dust and wear
Microorganisms that can thrive in warm, moist environments
Left unaddressed, these contaminants can:
Shorten equipment life
Cause corrosion in pneumatic tools and pipelines
Ruin product batches (especially in food, beverage, and pharmaceutical sectors)
Lead to regulatory compliance issues
Increase unplanned downtime and maintenance costs
That’s why air treatment systems are an essential part of any reliable compressed air network—and why Powerex’s TDD Air Treatment Skid is such a valuable addition.
What Is the TDD Industrial Air Treatment Skid?
The Powerex TDD Skid is a turnkey, skid-mounted regenerative desiccant dryer system that removes moisture and contaminants from compressed air, delivering ISO 8573.1 Class 1.2.1 air quality.
Designed for ease of installation and consistent performance, this system includes:
A dual-tower desiccant dryer
Pre- and after-filters for particulate and coalescing filtration
Integrated control panel with monitoring capabilities
Compact skid frame for plug-and-play setup
Optional dew point monitoring and pressure gauges
It’s a fully integrated air treatment system that can be placed inline with a compressor, requiring no additional housing, structure, or buildout.
Key Features of the TDD Air Treatment Skid
1. -40°F Dew Point Dry Air
At the heart of the system is its ability to produce air with a dew point as low as -40°F, making it ideal for critical applications where even a trace of moisture can cause failure or contamination.
This ensures:
No condensation in air lines
Protection from freezing in cold environments
Maximum longevity for pneumatic tools and actuators
2. Twin-Tower Desiccant Dryer
The regenerative desiccant dryer uses two towers filled with moisture-absorbing desiccant media. While one tower is drying the air, the other is being regenerated, allowing for continuous, uninterrupted operation.
Advantages include:
Constant air flow with no dips in quality
Highly effective drying for sensitive or high-purity systems
Long service intervals and low operating noise
3. Integrated Filtration
Each TDD skid includes:
A pre-filter to remove oil aerosols and particulates before air enters the dryer
An after-filter to capture desiccant dust and fine particles downstream
This multi-stage approach ensures that air is clean, dry, and ready for use—compliant with ISO 8573.1 Class 1.2.1 standards.
4. Plug-and-Play Installation
Because the system is skid-mounted, it arrives fully assembled and factory-tested. Simply connect to your compressor and air piping and you’re ready to go.
This minimizes:
Installation time
Engineering requirements
Commissioning headaches
Downtime for system upgrades
5. Optional Dew Point Monitoring
With the optional dew point monitor, operators can track system performance in real time and schedule maintenance only when needed—saving time and money while improving reliability.
Applications Across Industry
The TDD Air Treatment Skid is versatile and powerful, making it an ideal solution for:
Pharmaceutical manufacturing – Prevents contamination in cleanrooms and packaging lines
Food and beverage – Ensures air that comes in contact with product or packaging is free of oil and moisture
Electronics assembly – Protects sensitive circuitry from water vapor and particulates
Automotive – Powers tools and robots without damaging control systems
Plastics and injection molding – Prevents air bubbles or defects in molded parts
Paint and finishing shops – Delivers clean air that doesn’t affect coating consistency
Any process that relies on dry, clean air will benefit from the reliability and efficiency of this skid-based system.
Real-World Example: Food Packaging Plant in Chattanooga, TN
A food processing facility was experiencing moisture-related failures in its pneumatic packaging line, including frequent seal malfunctions and sensor issues. Their existing dryer was underperforming, and they were concerned about compliance with FDA and SQF guidelines.
Solution: Industrial Air Services installed a Powerex TDD Skid between their compressor and packaging equipment.
Results:
Moisture problems eliminated within 24 hours
Reduced packaging line downtime by 35%
Passed third-party air quality audit
Maintenance intervals extended from monthly to quarterly
