Why Choose Our Heated Regenerative Desiccant Air Dryer
(1) Custom Stainless Steel Material
We know that normal desiccant dryers for air compressors are carbon steel. However, many industries have sanitary requirements for air quality. So it must use the stainless steel. Lingyu Machinery has already produced many SS304 heated desiccant air dryers. The Twin Towers must be SUS304. Moreover, other spare parts must also be stainless steel, such as valves, heaters, silencers, pressure gauges, etc.
In addition, other offshore platforms and marine have higher requirements. They usually need the SS316 heated regenerative desiccant air dryer. This is because 316 stainless steel is resistant to corrosion by chloride ions. Some customers also accept the 304 stainless plus special coating. For all the heated desiccant dryers with the above requirements, we can produce them.
(2) Save More Energy
There is an electric heater in the desiccant air dryers for compressed air. When starting regeneration, it will use less product air to purge. The average air loss of a heated desiccant dryer is 6%. But a heatless air dryer is about 13%. Below, we will compare the operation costs of two desiccant dryers.

In conclusion, the heated desiccant dryer is more energy-saving. The heated regenerative desiccant air dryer can save more CNY118230 each year.
(3) With Multiple Functions
Firstly, our heated desiccant dryer adopts microcomputer intelligent automatic control. The air supply is continuous and stable. There will be no intermittent outage phenomenon. Easier to handle. It can monitor operating data, such as cycle time, working status, heater temperature, etc.
Moreover, our heated regenerative desiccant air dryer is equipped with PLC. So it has a remote on/off function. Due to the passive, normally open, dry contact, chain control can also be realized. In addition, the adsorption dryer also has an alarm function. Equipment operation is more secure. Maintenance is also more convenient.
(4) Stable And Reliable Pressure Dew Point
Our desiccant type air dryer can ensure 100% -40℃ dew point. This is because our heated desiccant dryer has sufficient adsorbents. Take this 45m³/min dryer as an example. There are more than 900 kg of adsorbent in the Twin Towers. Besides, there are more molecular sieves than alumina. In addition, our heated regenerative desiccant air dryer has structural advantages. Therefore, it can guarantee a very low-pressure dew point. And the fluctuation of the dew point operation curve is small.
FAQs
The lead time of our ss304 heated desiccant dryer is about 40~50 days.
Sure. You can require to add a dew point meter. Usually, we use the Suto brand.
Twin towers are SUS304. In addition, pipes, valves, heater, silencer, pressure gauge, and temperature sensor are all in stainless steel.
It is one year. And we will supply technical services all the time.
