What Is a Desiccant Air Dryer? 

A desiccant dryer, often called an adsorption dryer, is a type of industrial equipment that uses desiccant materials to remove moisture from the air that flows through it. In simple words, if you need dry and clean air, a desiccant air dryer is what you need. 

Dryers are widely used components of compressed air machinery that dry compressed air. Desiccant dryers, in particular, are necessary for processes and applications that need incredibly high-quality air or for applications that require an ultra-low dew point, often around -40°C to -40°F. 

These dryers are made to minimize the quantity of moisture in compressed air. It is crucial to have air at a consistent, predictable dew point for demanding areas like food processing or pharmaceuticals.

Desiccant air dryers operate on a straightforward basic principle: moist air passes through hygroscopic (desiccant) and is subsequently dried. The desiccant gradually becomes saturated with absorbed water due to water vapor transfer from the wet compressed air into the desiccant. Thus, the desiccant must be periodically regenerated to restore its drying ability.

An industrial desiccant air drier is called “regenerative” if it can replenish its desiccant by turning the adsorptive process around. Regenerative desiccant dryers typically employ paired desiccant-packed towers to allow for simultaneous water absorption and material regeneration.

Water vapor in compressed air equipment may lead to frozen air lines, premature failure, corrosion, quality and control problems, and other technical issues. Hence, a desiccant air drier system is needed to remove moisture from compressed air to clean it. These systems can be used in any industrial application requiring durable machinery and outstanding quality control.

Desiccant Air Dryers: Commonly Applications

Industrial applications that require compressed air most commonly use desiccant air dryers. For instance, the oil and gas sector employs compressed air in practically all of its processes, from oil recovery to the transportation and refining of petroleum. 

These procedures typically include equipment that is prone to damage from moisture. Most industries benefit from using a desiccant air drying system because it slows down the wearing and deterioration of moisture-sensitive parts. 

Here are some common applications:

  1. Blowing plastic molds:  Pellets need to be dried before processing.
  2. The manufacture of electronics: Electronic parts such as printed circuit boards (PCBs). They must be protected against moisture to prevent short circuits or oxidation throughout production.
  3. Power stations: Power station. Different valve actuators are controlled by compressed air, and an actuator’s failure might result in a power plant’s shutdown. The operation of the actuator is more secure when the air is of higher quality.
  4. F&B industries: To prevent the development of microorganisms, packaging machines with direct air contact must have a dew point of at least -40°C.
  5. Marine: Rigs that are offshore or ashore – N2 (-70°C PDP) production, notably for ships using LNG. Only dry air should be transported through outside plumbing since moisture would cause the pipe to start freezing.
  6. Laser Cutting: For optimal cutting results, dry air keeps the lenses dry and clean. 

 

Benefits of Using Desiccant Air Dryers

Compared to alternative drying units, desiccant plastic dryers offer various benefits, including higher efficiency, lower cost, and cutting-edge technology: 

 

  1. Cost Effective Solution 

Desiccant dryers are often more expensive than alternative drying solutions but are ultimately worthwhile. After using it once, you will understand and appreciate its usefulness in the long run. Desiccant dryers help reduce extra costs and raise the overall performance of your operations, which may boost sales and lower operating costs.

For instance, the desiccant drying method minimizes contamination issues in the desiccant beds, which were common with previous versions. Moreover, it requires less maintenance. The machine’s capacity to monitor dew points and reuse desiccants also lower material costs.

 

  1. They Simultaneously Perform Three Functions 

Desiccant dryers are among the most popular and reliable dryers in the market for a reason. These systems perform three tasks, i.e., regeneration, cooling, and drying, which sets them apart from similar systems. Their closed-loop drying method minimizes air pollution inside your facility while removing contamination issues related to desiccant beds.

Desiccant dryers have several technological advantages over conventional plastic dryers, which makes them much more effective and dependable. They include a timing belt, integrated controller, and dew point controller, among other things.

 

  1. Help Increase Efficiency and Productivity 

You can boost productivity in your plant and lower your company’s energy consumption at the same time using desiccant drying. The continuous, closed-loop drying desiccant machines enable various sections to go through the drying, regeneration, and chilling processes simultaneously. 

Thus, this keeps the resin flowing quickly from one step to the next and enables moisture absorption steadily. 

Moreover, most desiccant dryers have various essential parts that increase their energy efficiency with time. Certain desiccant drier methods have been shown to reduce energy use by 25% to 30%.
