Orion air dryer is a famous gas dryer brand, highly appreciated and most used in Japan. In Vietnam, Orion air dryers always account for the largest sales in the market because they are suitable for the climatic conditions in Vietnam, and are used by all air compressor brands from Japan in the system.

Absorbent air dryer from Japan's Orion brand

Orion adsorption air dryer There are 2 bulbs containing silica gel or other absorbent substances with the principle of taking turns dehumidifying, this bulb absorbs moisture and the other bulb regenerates. This type of air dryer has the disadvantage of compressed air loss ranging from 10% to 20% (used to dry desiccant during regeneration).
Dew point temperature is achieved from -40 to -70℃　PDP. Therefore, compressed air will be almost completely dry. Absorption air dryers are used for factories that require high air quality such as food, pharmaceuticals, dairy, nanotechnology, etc.

Depending on the environment and installation location of the air compressor, the compressed air stream (compressed from outdoor air) will contain a certain amount of impurities such as dirt, water and possibly oil vapor (for type of oil-filled air compressor)... and then it can have some impact on equipment that uses compressed air to produce quality products, especially mechanical manufacturing, steel, corrugated iron factories, Dip plating, coating, garment, coffee, cashew nuts, etc. Therefore, most factories have high requirements compressed air quality are using the system Orion absorption air dryer to separate water, dry and clean compressed air before supplying it to the equipment used.

What is an Absorption Dryer?

Absorbent air drying is purely a physical gas treatment process (unlike the chemical form of adsorbent air drying). The steam is attached to the desiccant by adhesion. Water molecules are "sticky" to the inside or outside of the absorbent surface without any chemical reaction occurring.

The absorbent has a porous structure and a large internal contact surface area. Common absorbents are: Aluminum Oxide, Silicagel, Activated Carbon and Molecular Membranes. Different sorbents are used for different regeneration processes.

Features

• Suitable for small systems with low air flow

• Simple installation

• Can be used in high temperature environments

The amount of absorbent used is small

• High operating costs: part of the compressed air used to regenerate the absorbent will be discharged directly to the outside and cannot be used.

• The regeneration process does not require additional external energy sources

• The percentage between the compressed air involved in the regeneration process and the compressed air produced by the air compressor decreases as the compression pressure increases.

• Requires air filtration before entering the absorption air dryer: removes oil, liquid water and dirt particles.

• Filter compressed air after going through several air dryers: remove absorbent substances that follow the compressed air out.

Features of Orion Absorption Gas Dryer.

The Orion absorption air dryer is a reliable solution for compressed air drying in industries that require high air quality. A special feature of this dryer is the use of two bulbs containing silica gel and other absorbents, with the principle of taking turns dehumidifying. When one bulb absorbs moisture, the other bulb is active in regeneration. Although there is a disadvantage of compressed air loss of 10% to 20% during the regeneration process, the efficiency achieved is significant.

The dew point temperature that Orion air dryers can achieve ranges from -40 to -70℃ PDP (Pressure Dew Point), ensuring that compressed air is dried almost completely. This is very important in industries such as food, pharmaceutical, dairy, nanotechnology, where gas quality is required to be at the highest level to ensure the final product is always of the best quality.

Orion absorption air dryers represent efficiency, reliability and high quality. If you operate in industries that require compressed air with extremely low humidity and optimal quality, the Orion absorption air dryer would be an option worth considering.

HEATLESS REGENERATIVE ABSORPTION GAS DRYER (heatless)

The regeneration process for the non-thermal method usually takes about 5 minutes. Therefore, water vapor is only adhered to the outer surface of the absorber.

Refrigerated regenerative absorption air dryers operate on a pressure change process. This regeneration method does not require the use of heat. Part of the dried compressed air stream will be used for regeneration. This compressed air line is pressured down to 1 bar, so it is very dry. Then enters the tank in the process of regeneration B. The compressed air stream blows the steam stuck on the absorber and carries the water straight out through the exhaust valve.

Principle of operation

During the drying process, compressed air containing water vapor is passed through an absorption tank. The water molecules are then stuck to the absorbent. This process generates heat. The absorbent needs to be “regenerated” when the adhesive force is balanced by water reserves. That means water needs to be removed from the absorbent. Therefore, it is necessary to have two absorption tanks operating in parallel continuously. While tank A is drying compressed air, tank B will be regenerated when no compressed air passes through and vice versa.
