High Temperature Regenerative Air Dryer

The Refrigerated Dryer Alternative

For hot, humid compressed air

Optimize performance in demanding mobile environments with a mobile regenerative air dryer built for high-temperature conditions. This all-in-one regenerative air dryer with an aftercooler removes excess heat and moisture to deliver clean, dry air wherever you work. Keep moisture under control to ensure consistent spray patterns and to protect your tools and equipment. If you need a high temperature regenerative air dryer for spray foam rigs, paint refinishing, beverage canning, or other hot, humid applications, this system is built for it.

Lowers temperature of hot air

The aftercooler lowers the temperature of the compressed air, with the ability to cool it to 5-20°F above ambient air temperature.

Bonus: it has a pressure drop of <1 PSI.

Removes particulates, bulk water, & oils

The pre-filtration includes the water separator and oil coalescing filter to remove liquid water, bulk oils, and particulate.

Removes remaining water vapor

The regenerative towers use sweep air to regenerate the towers during operations while removing any remaining water vapor. It's like changing the desiccant every two minutes.

Choosing the right dryer
No single dryer technology is ideal for every application - we are here to help you select the solution that best matches your operating conditions.

Why combine an aftercooler with a regenerative dryer?

What is the average air consumption and cycle time?

*Dryer flow rates based on 100°F at 175 PSI an outlet pressure of 100 PSI. (Minimum inlet pressure 80 PSI Lower inlet pressure and higher temperatures affect the performance and quality of the downstream air)

What makes this system suitable for mobile or vehicle-mounted installations?
How do you dry compressed air when inlet temperatures are high?

How does this system compare to a high-temperature refrigerated dryer?

High-temperature refrigerated dryers are commonly used in stationary compressed air systems and rely on refrigeration to condense and remove moisture. In many applications, they are paired with separate aftercoolers and filtration.

This system integrates an aftercooler, pre-filtration, and regenerative drying into a single, wall-mounted unit. It is designed for mobile and high-temperature applications where inlet conditions can vary and installation space is limited.

Feature	High Temp Refrigerated Dryer	Traditional Refrigerated
System Integration	All-in-one system: aftercooler, pre-filters, and regenerative dryer	Dryer only; aftercooler and filters often installed separately
Space Needed	Wall-mounted, compact	Floor-mounted, stationary
Mobile Reliability	Designed for mobile applications	Not always designed for mobile environments
Condensate Drains	Float drain for consistent condensate removal	Timed or electric drains common

Are refrigerated dryers still a good option?

21999-1250 aftercooler

Aftercooler

The aftercooler cools hot air leaving air compressors quickly, forcing moisture to condense and drain off early in the process. Each unit is wall-mountable and offers six different configuration options to optimize drying and airflow in tight or mobile setups. This helps reduce the load on your system and supports cleaner, drier air.

Regenerative Dryer

All regenerative air dryers are designed to be compatible with any spray foam rig and most point-of-use applications. A regenerative dryer is wall-mountable to save space, and efficient at removing humidity so your application process stays dry, keeping water out of critical piping, and ensuring a professional final product.
