Why Choose Our Modular Type Adsorption Compressed Dry Air
① More Energy Saving
The air compressor desiccant dryer has low air consumption. The air consumption of the modular heatless dryer is generally 7%. But the double tower heatless dryer is generally 13%. 加えて, its structure is simple. それで, the air pressure loss is lower. Compared to traditional adsorption air dryers, it can reduce operation costs by 30%~60%.
② Stable Performance
The air compressor dryer system uses high-quality adsorbents. それで, the performance of the air desiccant dryer is stable. It adopts a decentralized adsorption unit structure. It can greatly increase effective adsorption area. したがって, 露点がより安定します.
③ More Hygienic
The main material is magnesium-aluminum alloy. また, do anti-rust treatment by oxidation. それで, it can effectively prevent secondary pollution. Especially suitable for the food and pharmaceutical industry. Life expectancy can be up to 30 年.
④ Intelligent Control
This compressed dry air system uses PLC. It has a friendly human-computer interface. So it can realize remote control. The operation is simple and easy to understand. エア供給は継続的かつ安定しています. No intermittent air cuts.
⑤ Small Size And Light Weight
The overall structure is compact. Beautiful appearance design. The modular desiccant dryer is easy to transport and install. We can also install it in narrow spaces. So it does not take up a lot of production space.
そのほか, the modular adsorption dryer is not a pressure vessel. それで, it doesn’t require annual re-inspection. Significant time and cost savings.
⑥ Low Later Maintenance Cost
まず最初に, fewer valves are used compared to the twin-tower air dryer. それで, the failure rate is lower. Large desiccant dryers use air cylinders. Maintenance is simple and convenient. また, the cost of the adsorbent is low. So there are fewer replacements later. 例えば, a 3.8m³/min heatless module air compressor desiccant dryer requires 35 adsorbents. But a 3.8m³/min heatless twin tower desiccant dryer requires 60KG adsorbents.
Why Modular Desiccant Air Compressor Dryer System is More Energy Saving
Take a 110KW air compressor as an example. The 5-year electricity consumption of several compressed dry air systems is as follows:
- ① Double tower heatless adsorption dryer: 空気消費量は約 13%.
So energy consumption=11012436513%*5=CNY626340.
- ② Twin tower micro-heat regenerative air dryer: air consumption is about 7%. And the electric heating wire power is 4KW.
So energy consumption=1101243657%5+4124365*5=CNY512460.
- ③ Combination desiccant air compressor dryer system: The air consumption is 5%. The power of a refrigerated dryer is 4.5 kW.
So energy consumption=1101243655%5+4.5124365*10=CNY438000.
- ④ Modular air compressor desiccant dryer: The air consumption is 5%. And the electricity consumption is 5 年:
1101243655%*5=CNY240900.
The modular air compressor dryer system is composed of several cavities. It is equivalent to this situation: several small adsorption towers take adsorption simultaneously. So it can maintain a stable compressed air dew point.
And this structure has benefits. It increases the surface area where the adsorbent and compressed air contact. The contact time will also increase. それで, the water absorption effect is multiplied. ついに, it greatly reduces the regeneration air consumption.
It is not like a traditional twin-tower compressed dry air system. The double-tower air dryer has a dead angle of adsorption. Short contact time with desiccant. そのほか, the contact is insufficient. Insufficient drying and regeneration. It needs much air to purge the adsorbents to achieve the dew point. したがって, the regeneration air consumption is large.
How Does Modular Air Compressor Desiccant Dryer System Work
The heatless modular compressed dry air system has multiple aluminum cavities. Each group has two cavities. Each cavity is filled with desiccant beads. It’s to dry the moist compressed air. それから, one cavity is working (drying), and beads will absorb moisture. 現時点では, the other side will regenerate by PSA.
再生中, some dry air expands to atmospheric pressure. Take away the moisture in the adsorbents. それで, the desiccant beads can regenerate. We usually use it with a refrigerant dryer and precision filters. したがって, it will enhance the performance and reliability of the air compressor desiccant dryer system.
When Group A is adsorbing, the intake valve A1 opens. 同時に, muffler exhaust valve B1 closes. The outlet check valve C1 of the air compressor desiccant dryer system also opens. Compressed air enters the downpipe from A1. それから, enter the upper trachea after adsorption. The dry air flows to the air consumption section through C1. Part of the dry air enters Group B through regeneration valve D1. それで, Group B started regeneration.
When Group B is regenerating, intake valve A2 is closed. Muffler exhaust valve B2 of the compressed dry air system opens. 同時に, the outlet check valve C2 closes. The regeneration air enters the upper air pipe through valve D2. The air performs analytical regeneration on the desiccant beads. ついに, it will discharge the moisture from the muffler exhaust valve B2.
How to Install Filters to Air Compressor Desiccant Dryer System
The filters can improve our compressed air quality. 同時に, it can protect our desiccant beads.
(1) Install The Pre-filter Before Adsorption Air Dryer
あれは, install water-removal and oil-removal filters. Add them in front of the air compressor desiccant dryer system. If there is a lot of liquid water, it will affect the dryer effect. This results in an increase in the outlet dew point. 加えて, oil mist can seriously pollute the desiccant beads. It will also raise the dew point. 同時に, it will shorten the service life of the adsorbent. 濾過後, the liquid microparticle content will reach 0.01 μm. And the residual content of oil vapors will reach 0.01ppm.
(2) Install The Post-filter on The Compressed Dry Air System
The desiccant beads are under pressure and shock for a long time. It will generate some adsorbent dust. それで, we need to ensure the quality of the downstream compressed air. それから, installing the post-filter on the air compressor desiccant dryer system is necessary. ここ, we use the dust-removal filter.

High-efficiency activated alumina + high-efficiency molecular sieve. Both are from China famous brand.
It is about 8000~12000 hours. The specific replacement time is based on the compressed air quality.
もちろん. There are two advantages to installing the compressed air filters. まず最初に, it can ensure the compressed air quality. 第二に, it can extend the lifetime of desiccant dryer and adsorbent.
The dew point can be -20℃ and -40℃ for modular adsorption air dryers.
