Different from Carbon steel material product
Using 304S stainless steel for heat exchanger, water separator and air connections can avoid the secondary pollution to air quality, so the SSD series dryer can be directly used for food ,medicine, semiconductor, senior spraying field and etc.
Nano anticorrosive coating on air condenser makes the useful life longer.
Energy saving and environmental protection
Heat exchanger is following Europe and America advanced plate-fin structure, highly heat-efficiency;
The inlet and outlet temperature difference of pre-cooler is 3-5℃, which is much more better than the similar products and minimize the outlet relative humidity and avoid condensation in the piping.
Outlet compressed air relative humidity is low, the below air pipe surface without Condensation phenomenon.
The pre-cooler reclaim nearly 90% compressed air, and greatly reduces the evaporator load, so the power consumption of the refrigerant compressor is low, only 70% of the normal one.
Friendly refrigerant is adopted for all series dryers.
Security and Reliability
Multiple overload protection.

High-pressure, moisture-laden compressed air enters the dryer. First, it usually passes through a heat exchanger where it is cooled down. As the air cools, the water vapor within it condenses into liquid water. For example, in many industrial applications, the compressed air coming from a high-pressure compressor might be at a relatively high temperature (say around 80 - 100 °C or even higher depending on the compression ratio), and through cooling in the dryer's initial stage, the temperature can be reduced to a level where significant condensation occurs, typically to around 20 - 30 °C.
After the high-temperature compressed air enters the dryer, it first passes through the pre-cooler to reduce the temperature, so that the water vapor in it reaches a saturated state and begins to condense into water droplets. Then, the air enters the evaporator, and the refrigerant in the evaporator absorbs the heat of the air, so that the air temperature is further reduced, and more water vapor condenses into liquid water and is discharged through the drainage device. The dehumidified air then passes through the post-cooler to raise its temperature back to close to the ambient temperature to prevent the generation of condensed water in the subsequent pipelines.

FAQ
How does it work?
It is a device used to remove moisture from compressed air systems. It works by cooling the compressed air, which causes the moisture in the air to condense into water. This water is then removed from the system, ensuring that the air remains dry. The dryer typically uses a refrigeration cycle to cool the air, lowering the temperature to a point where moisture can be easily separated. It helps prevent rust, corrosion, and damage to pneumatic tools and equipment.
Why should I use a Air Dryer in my industrial operations?
Using a Compressed Air Dryer helps protect your equipment from damage caused by moisture, such as rusting and corrosion. It also ensures that your compressed air is clean and dry, which is crucial for optimal performance of pneumatic tools, machinery, and other sensitive equipment. Additionally, the dryer improves energy efficiency by maintaining air quality and reducing the chances of blockages or malfunctions in the system.
What are the key features of this Air Dryer?
Key features of a Refrigerated Compressed Air Dryer include a high-efficiency refrigeration system, moisture removal through condensation, a built-in condensate drain, and energy-saving modes. These dryers are designed to operate in a wide range of environments, offering durability and reliability. Some models also include adjustable pressure dew points, which are essential for maintaining consistent air quality.
How do I select the right Air Dryer for my application?
Selecting the right Compressed Air Dryer depends on factors such as the air flow rate, the pressure rating, and the required dew point. You should also consider the temperature range of your application, as some dryers are designed for high-temperature environments. Additionally, factors like energy efficiency, the size of the air compressor, and the volume of air being processed will influence your choice. Consulting with a manufacturer or supplier can help ensure you select the best model for your needs.
What maintenance is required for a Air Dryer?
Regular maintenance is essential to ensure optimal performance of a Air Dryer. This includes periodic cleaning of the condenser coils, draining the condensate, checking the refrigerant levels, and inspecting the air filters. It is also important to monitor the dryer's cooling system to ensure it is operating efficiently. Some models may require more specialized maintenance, such as refrigerant charge checks, depending on the complexity of the refrigeration system.
Can it handle high-pressure systems?
Yes, they are designed to handle high-pressure systems, although the specifications of each unit will vary. It is essential to choose a model rated for your system's pressure range. High-pressure air dryers typically use more robust components to manage the increased demands and ensure effective moisture removal without compromising performance.
What certifications should I look for in this product?
When purchasing a Air Dryer, look for certifications like ISO, CE, and UL, which ensure the product meets international safety, quality, and environmental standards. These certifications are essential for compliance in many industries and guarantee that the dryer has passed rigorous testing for reliability and efficiency. Having such certifications also indicates that the product is manufactured according to best practices and industry regulations.
