ZEKS REFRIGERATED CYCLING AIR DRYER 200-1,600 SCFM

The ZEKS Refrigerated Cycling Air Dryer is designed to remove moisture and contaminants from compressed air systems with flow capacities from 200 to 1,600 SCFM. Using HeatSink technology, the dryer cools compressed air through a refrigerated thermal mass, causing moisture and contaminants to condense for efficient separation and removal.

Its True-Cycling operation allows the refrigeration system to cycle off during periods of lower demand while the thermal mass continues cooling the compressed air. This helps reduce unnecessary refrigeration energy consumption compared with conventional non-cycling dryers that operate continuously.

For compressed air systems where moisture control, reliable operation and energy efficiency are important, the ZEKS refrigerated air dryer provides a practical solution for maintaining treated compressed air.

How Does a Refrigerated Air Dryer Work?

A refrigerated air dryer reduces moisture in compressed air by cooling the air to condense water vapour and other contaminants.

The ZEKS HeatSink™ system uses refrigeration to cool a thermal mass. As compressed air passes through the dryer, it is cooled by this stored thermal energy. The resulting condensation is then separated from the compressed air through a high-efficiency separator.

The refrigeration system does not need to operate continuously. During periods of lower compressed air demand, the stored cooling capacity allows the refrigeration system to cycle off while moisture removal continues.

This True-Cycling™ technology helps the dryer adapt to changing air demand while reducing unnecessary energy consumption.

Why Use a Refrigerated Air Dryer for an Air Compressor?

Compressed air naturally contains moisture. When this moisture is not properly removed, it can move downstream through the compressed air system and affect equipment and processes.

A refrigerated air dryer for air compressors helps condition compressed air by removing condensed moisture before the air reaches downstream equipment.

The ZEKS cycling dryer is designed for applications where users need:

The appropriate dryer should always be selected according to the compressor's airflow, operating pressure, inlet temperature and application requirements.

ZEKS HeatSink™ Technology

The HeatSink™ design combines refrigeration with a thermal mass to provide cooling capacity even when the refrigeration system is not actively running.

The process can be understood in four stages:

Cooling : The refrigeration system cools the thermal mass inside the dryer.

Heat Transfer : Compressed air passes through the cooled system and its temperature is reduced.

Condensation : As the compressed air cools, moisture and contaminants condense.

Separation : A high-efficiency separator removes the condensed moisture from the compressed air stream.

This approach allows the dryer to respond to variations in compressed air demand rather than running the refrigeration system continuously.

True-Cycling™ Operation for Changing Air Demand

Compressed air demand is rarely constant throughout an industrial facility. Equipment may operate intermittently, production schedules may change, or sections of the plant may shut down temporarily.A conventional refrigerated dryer may continue operating its refrigeration system even when compressed air demand is low.

The ZEKS True-Cycling™ system is designed differently. When cooling is not required, the refrigeration system cycles off while the thermal mass retains stored cooling energy.

This can help reduce energy use during periods of lower demand while continuing to provide moisture removal.

Key Features of the ZEKS Refrigerated Air Dryer

Multi-Layer Heat : The multi-layer heat design supports the cooling and heat-transfer process within the dryer.

Advanced Digital Controller : The advanced digital controller provides control of the dryer operation and helps users monitor its functioning.

Fully Hermetic Refrigeration Compressor : A fully hermetic refrigeration compressor is used as part of the refrigeration system.

R134A Refrigerant : The dryer uses R134A refrigerant as specified for this product range.

Efficient Refrigeration Condenser : The refrigeration condenser is designed to support efficient operation of the cooling system.

Timed Solenoid Condensate Drain : The timed solenoid drain helps remove collected condensate from the dryer.

Available Options

Depending on installation and application requirements, available options include:

These options allow the dryer configuration to be adapted to different compressed air system requirements.

Choosing the Right Refrigerated Compressed Air Dryer

Selecting a dryer is not simply about matching the SCFM number. The dryer needs to suit the complete compressed air system.

Before choosing a refrigerated compressed air dryer, consider:

Airflow : Determine the compressed air flow the dryer needs to handle. The ZEKS range covered on this page is designed for 200–1,600 SCFM.

Operating pressure : Check the pressure at which the dryer will operate.

Inlet air conditions : Inlet temperature and ambient conditions can influence dryer performance.

Air demand pattern : If your compressed air demand varies throughout the day, cycling technology can be an important consideration.

Installation requirements : Consider available space, electrical requirements, condensate drainage and access for maintenance.

Application : Understand the required compressed air quality for the equipment and process downstream.
