Thanks to its revolutionary solid desiccant, the new PH HE adsorption dryer from Pneumatech raises the bar in efficiency, reliability, low maintenance and versatility.
Thanks to its groundbreaking structured desiccant, Pneumatech’s PH 45-690 HE adsorption dryer offers unprecedented benefits and the lowest cost of ownership. It is the most efficient dryer available on the market today with an optimal, even airflow and low-pressure drop.
Because structured desiccant decays at a much slower rate than desiccant beads, the PH HE’s service intervals are 40% longer. The desiccant blocks also make maintenance much faster and easier.
The PH HE takes dryer reliability to another level. While desiccant beads create dust that can cause dryer failures and compromise your production, the PH HE’s solid desiccant eliminates this risk. The result is an absolutely stable pressure dew point every day of the year. The PE HE’s robust design and exclusive pneumatic valves ensure outstanding drying results even in tough conditions. The easy-to-use PureLogic™ controller allows you to optimize the performance and efficiency of your PH HE.
All materials can adsorb and desorb water, only the degree of adsorption is different per material. Desiccant used in adsorption dryers is specifically designed to adsorb moisture. Desiccants can release water particles by adding some form of energy to them. This is called regeneration.
Pneumatech adsorption dryers consist of two towers, both filled with desiccant, which alternatively operate in the adsorption or regeneration cycle via a controlled switching mechanism. Once the desiccant is saturated in one vessel the process is reversed, and the second vessel starts adsorbing.
Adsorption dryers are used when PDPs (pressure dew points) from -10°C/14°F down to -70°C/-94°F are to be achieved. They make use of a material that has a high affinity to moisture, known as hygroscopic material or desiccant. The adsorption of moisture causes the desiccant to be gradually saturated with water. Therefore, the desiccant needs to be regenerated regularly to regain its drying capacity. Adsorption dryers are typically built with two drying vessels (“towers”) for that purpose: the first tower will dry the incoming compressed air while the second one is being regenerated. To ensure continuity, each vessel switches tasks when the other one is completely regenerated. For critical applications and applications below 5°C/ 41°F ambient temperature, an adsorption dryer is recommended
The benefits of using desiccant dryers
Using desiccant air dryers for compressed air brings numerous benefits:
1. Moisture removal
One of the primary advantages of desiccant dryers is their ability to achieve very low Pressure Dew Points (PDPs). This level of dryness is crucial in processes where even minimal moisture can cause significant issues, such as in pharmaceuticals, food processing, and electronics manufacturing.
2. Protection of equipment
By providing extremely dry air, desiccant dryers protect pneumatic machinery, control systems, and pipelines from moisture-related damage and corrosion. This extends the life of the equipment and ensures smoother, more reliable operation.
3. Improved product quality
In industries where moisture can compromise the quality of the end product, such as in painting or chemical processing, the ultra-dry air produced by desiccant dryers is essential for maintaining high-quality standards.
4. Energy savings
Certain types of desiccant dryers, like zero purge and blower purge models, are designed for energy efficiency, reducing operational costs over time.
5. Versatility and reliability
Desiccant dryers are versatile, functioning effectively in a wide range of temperatures and environments. They are reliable in delivering consistent performance, which is critical in industries where air quality cannot be compromised.
