Heated Blower Desiccant Air Dryer Introduction
The desiccant air dryer is the dual tower. Lingyu is the top reliable regenerative adsorption air dryer manufacturer in China. This product is a zero air loss heated blower air dryer. So its regenerative gas consumption is 0%. For this kind of dryer, our pressure dew point can be -20℃ and -40℃.
Different from a heatless air dryer, it is an energy-saving machine. Both heating regeneration and cold purge use ambient air. It can effectively save the compressed air. So the whole operation can achieve zero gas consumption. Because it is energy efficient, it is widely used in steel, lithium batteries, chemical metallurgy, medicine, and other industries.

Advantages of Our Desiccant Air Dryer for Air Compressor
Our heated blower purge desiccant air dryer has many advantages. Our regenerative air dryers usually work together with famous air compressor brands. These air compressor brands are Atlas Copco, Ingersoll Rand, Sullair, etc.
(1) Low Point & High Stability
It can 100% ensure -40℃ pressure dew point. Besides, the dew point curve is very smooth. Firstly, our dryers use high-quality desiccant beads. That is a high-efficiency alumina and 4A molecular sieve. We use a Sino-foreign joint venture adsorbent brand. Besides, the adsorbent filling is sufficient. Take the 65m³/min heated blower air dryer as an example. The total filling volume is close to 2000 kg. This is more than other manufacturers.
In addition, there is an airflow splitter at the bottom of the adsorption towers. Therefore, the compressed air can fully contact with the desiccant beads in the towers. Dry more thoroughly. Moreover, our dryer has an intelligent control system. It can adjust the operation of the absorption air dryer in real-time. So the dew point of our desiccant air dryer for air compressor is stable.
(2) Highly Energy Saving
This heated blower desiccant air dryer has zero air loss. It’s more energy efficient than the micro-heated dryer. The blower draws outside air for heating and regeneration. So it consumes no compressed air. This zero air loss dryer can save more than 60% of energy compared to a heatless air dryer. Below, we compare the operating costs of three different dryers. They are zero air consumption, heated blower purge, heatless, and micro-heated desiccant dryer.

(3) High Quality Spare Parts
Firstly, we adopt a multi-core drive intelligent control system. It can realize operation parameter signal acquisition/monitoring/display. So our heated blower air dryer is stable and reliable. Easier to handle.
Secondly, our heated blower purge desiccant air dryer has top-quality parts. For example, this zero air loss dryer comes with a Suto brand dew point meter. Besides, our desiccant air dryer for air compressors uses Germany-brand control valves. These pneumatic valves have a lifetime of up to 2 million on/off times. Moreover, they are high-temperature metal seated valves. In addition, we use the imported high-pressure blower. So our adsorption air dryer can operate stably.

How Does Heated Blower Air Dryer Work
The compressed air passes through the adsorbent layer. The moisture is separated from the wet air. After some time, adsorption reaches saturation equilibrium. Then, the blower blows out atmospheric air. An electric heater will heat this air. Afterward, it starts heating the regeneration of the desiccant beads. So it can restore the adsorption capacity of the adsorbents. In this way, the Twin Towers switch constantly and work in a cycle.

Q4: What is A Desiccant Dryer For An Air Compressor?
A4: It can remove the water in the compressed air deeply. And get super dew points, such as -20℃, 40℃, and 70℃. We often use it after the refrigerant air dryer. Usually, there are dual adsorption A/B towers in the dryer.
Q5: Do I Also Need A Refrigerant Dryer Before The Heated Blower Air Dryer?
A5: We usually recommend purchasing a refrigeration dryer as well. A refrigerated dryer removes water and cools temperature down. It is better able to meet the inlet air temperature requirements of the desiccant dryer. Moreover, it can increase the service life of the adsorbent. At the same time it ensures that the water removal effect more effectively.
