With multiple dryer technologies and system configurations available, Gardner Denver offers solutions optimized for virtually every compressed air application.

This product overview provides a comprehensive look at Refrigerated Air Dryers, including how they work, their benefits, sizing considerations, and an overview of the refrigerated dryer technologies offered by Gardner Denver to help you select the right solution for your operation.

Refrigerated Air Dryers remove moisture from compressed air by cooling it to condense water vapor, which is then separated and drained from the system. After drying, the air is reheated slightly before leaving the dryer, reducing downstream condensation in piping and equipment.

Refrigerated dryers are the most commonly used compressed air dryers because they offer an optimal balance of performance, reliability, and operating cost. They typically deliver pressure dew points around 38°F (3°C), making them ideal for most indoor industrial applications where freezing temperatures are not a concern.

How Refrigerated Air Dryers Work

1. Hot, saturated compressed air enters the dryer

2. Air is cooled using a refrigeration circuit

3. Water vapor condenses into liquid moisture

4. Condensate is removed via a separator and drain

5. Dry, clean air exits the system for use downstream

This proven process makes refrigerated air dryers a dependable and cost-effective choice for moisture control in compressed air systems.

Refrigerated Air Dryers are widely selected because they offer a strong combination of moisture removal, ease of operation, and lower energy consumption compared to alternative drying technologies.

Key Benefits of Refrigerated Air Dryers

• Consistent moisture removal for reliable compressed air quality

• Lower operating costs than desiccant dryers in most applications

• Simple design and maintenance

• Energy-efficient operation with cycling dryer options

• Compact footprint for easy integration into existing systems

Gardner Denver offers a range of Refrigerated Air Dryer technologies engineered to meet varying operating conditions, airflow requirements, and energy efficiency goals. Each type is designed to integrate seamlessly with compressed air systems and deliver dependable performance over the long term.

Non-Cycling Refrigerated Air Dryers

Non-cycling refrigerated air dryers operate continuously, maintaining a stable internal temperature regardless of compressed air demand. This design ensures a consistent pressure dew point under steady operating conditions.

Key Advantages:

• Simple, rugged design

• Reliable dew point control

• Ideal for applications with constant airflow

• Lower upfront cost compared to cycling dryers

Non-cycling refrigerated dryers are commonly used in facilities with stable demand profiles where simplicity and reliability are the top priorities.

Cycling Refrigerated Air Dryers (Energy-Saving Dryers)

Cycling Refrigerated Air Dryers are designed to reduce energy consumption by matching cooling output to actual compressed air demand. Instead of running continuously, these dryers cycle the refrigeration system on and off or use thermal storage to maintain dew point performance.

Key Advantages:

• Reduced energy consumption during low demand

• Lower operating costs over time

• Longer compressor and component life

• Environmentally responsible solution

Cycling refrigerated dryers are an excellent choice for facilities with variable airflow requirements or sustainability goals focused on energy efficiency.

High Inlet Temperature Refrigerated Air Dryers

Standard refrigerated dryers are designed for specific inlet temperatures. High inlet temperature refrigerated air dryers are engineered to handle hotter compressed air directly from the compressor discharge.

Key Advantages:

• Handles elevated inlet temperatures without upstream cooling

• Eliminates the need for separate aftercoolers

• Reduced installation footprint and system complexity

• Ideal for harsh industrial environments

These dryers are especially beneficial when space is limited or when compressors operate at higher discharge temperatures. 

Energy Savings Refrigerated Air Dryers

Gardner Denver’s energy savings series of refrigerated air dryers is designed to dramatically reduce energy consumption while maintaining ultra-low dew point performance.

Key Advantages:

• Efficiency through demand-dependent operations

• Reduced compressed air loss, minimizing wasted production capacity 

• Lower operating costs compared to traditional heatless dryers 

• Extended desiccant and valve life through optimized cycle timing

This model is ideal for facilities where compressed air demand fluctuates and efficiency is a top operational priority.

Large Capacity Refrigerated Air Dryers
