Desiccant Air Dryers

As a leading desiccant air dryer supplier, CRU AIR + GAS is committed to improving your operational efficiency. We bring premium-quality desiccant air dryers to your doorstep. We supply superior-grade desiccant air dryers to remove water vapour from your compressed air system effectively.

HLD Series Twin Tower Desiccant Air Dryers

BOGE’s HLD Series twin tower desiccant dryers are designed to remove water vapour from your compressed air system. This can lower the pressure dewpoint to -40 or even as low as -94 deg F! No liquid or ice crystals will form even if the compressed air temperature falls to forty degrees below zero. Designed for the most demand applications, BOGE’S HLD Series dryers are your solution for reliable, uninterrupted clean, dry air. The PLC monitors and controls your HLD dryer. The system monitors multiple inputs, showing pertinent data on the digital display and controlling the fully automated drying and regeneration cycles. With the optional Energy Saver Option, your dew point demand system uses a reliable precision hygrometer to continually monitor the outlet dew point and extend the cycle for maximum energy savings. This includes real-time outlet dew point indication and high dew point alarm.

DA Series Compact Desiccant Dryers for Air Compressor

In addition, we offer DA Series Compact Desiccant Air Dryers equipped with patented combined filters and desiccant cartridges. These dryers have the following features:

Feature Description
Combined Filters & Desiccant Cartridges The patented design includes built-in outlet filtration, high-density filled desiccant for maximum adsorption capacity, and easy-to-replace cartridges.
PLC Control System Reliable operation with ‘power on,’ ‘hours run,’ and ‘service required’ indicators. Memory retention allows for a continuous drying cycle.
Compressor Synchronization The energy-saving feature starts and stops the dryer based on signals from the compressor or point-of-use equipment, reducing purge loss.
Installation Flexibility Dryers can be installed on the floor or the wall by simply rotating the feet 90°.
Consistent Flow & Pressure Pressure equalization before switching columns ensures uninterrupted compressed air, consistent air pressure, and long desiccant life.
Optimum Dew Point Performance Dryers are standard set for a -40°F dew point, with an optional dew point of -94°F. Air velocity and desiccant contact time are carefully managed for optimal performance.
Energy Saving Dew Point Control Option A dew point sensor adjusts the cycle time based on moisture load, saving purge air. Also, it is easily retrofitted and has a dew point display for real-time monitoring.
-ES Option It reduces valve actuation, enhances service life, and comes with a 5-year valve warranty.
High-Performing Valves Includes integrated check valves and two pilot-operated solenoid valves for reliability.
Corrosion Protection High tensile aluminum columns are alocrom-protected and externally powder coated for maximum protection.

Frequently Asked Questions

What is a desiccant air dryer?

A desiccant air dryer is a device used to remove moisture from compressed air by using desiccant materials such as activated alumina, silica gel, or molecular sieves. These materials absorb or adsorb moisture, ensuring that the air remains dry for critical applications, preventing damage or malfunction due to water contamination.

How does a desiccant air dryer work?

The working principle of desiccant is based on its ability to adsorb moisture from the air. The desiccant material, often a porous substance, has a high surface area that allows it to trap water vapor. Compressed air passes through the desiccant bed, and the moisture adheres to the surface of the desiccant, leaving behind dry air. Once saturated, the desiccant is regenerated, often using heat or a portion of the dried air.

How often should I replace the desiccant in my air dryer?

The replacement frequency depends on the type of dryer and operating conditions. For heatless dryers, desiccant typically lasts up to 5 years, while in heat-regenerated dryers, it may need replacement every 2 to 3 years. Regular monitoring of dew point and desiccant condition is essential.

Can desiccant air dryers be used in all industries?

Yes, desiccant air dryers are versatile and used across various industries, including pharmaceuticals, food processing, electronics, and manufacturing, where dry compressed air is crucial to prevent

What is desiccant used for?

Desiccants are used for drying compressed air, gases, and certain materials in industries such as pharmaceuticals, food processing, electronics manufacturing, and packaging. They help to maintain the integrity of products sensitive to moisture, prevent rust and corrosion, and ensure that air systems operate efficiently.

What chemical is used in desiccant?

Common chemicals used in desiccants include silica gel, activated alumina, molecular sieves, and calcium sulfate. These substances have high surface areas that allow them to adsorb water vapor effectively, providing dry air or environments in various industrial applications.

How long does air dryer desiccant last?

The lifespan of desiccant in an air dryer typically ranges from 2 to 5 years, depending on the dryer type, operating conditions, and maintenance practices. Frequent monitoring of the dew point and the condition of the desiccant can help determine when it needs replacement.

What is the dew point of a desiccant air dryer?

The dew point of a desiccant air dryer is the temperature at which the moisture in the compressed air condenses into liquid water. Desiccant dryers are designed to lower the dew point of compressed air, typically to levels of -40°F (-40°C) or even lower, ensuring that the air remains dry and free from moisture.
