Desiccant Dryer
Heated Desiccant Dryer
Heated (Thermal) Desiccant Dryer
To achieve ultra-dry compressed air and prevent compressed air loss, it is essential to use highly absorbent desiccant materials with strong adsorption activity, especially at low moisture concentrations. Among the available industrial desiccants, molecular sieve and silica gel are considered the most effective options due to their superior moisture adsorption capabilities.
A key point to note is that while these materials are excellent at absorbing moisture, they are also resistant to releasing it. Therefore, the most effective method for fully regenerating these materials is through the application of high temperature during the regeneration process.
This process takes place in heated desiccant dryers, where air is drawn in through an independent blower (eliminating the need to use the compressed air from the package itself) and passed over a heating element. The resulting hot air is then directed through the desiccant material, effectively regenerating (fully drying) it. After the regeneration phase, the heater is deactivated, and once the desiccant is cooled, a small amount of dry air passes through the material to prepare it for the next moisture adsorption cycle.

Heatless Adsorption Dryer
Heatless Adsorption Dryer
The compressed air exiting the compressor contains a significant amount of water vapor particles, oil, and other impurities. The presence of water particles in the air coming from the compressor leads to oxidation, corrosion, and damage to the equipment that uses compressed air.
A heatless adsorption dryer (desiccant dryer) is used to remove these particles from compressed air, making it suitable for environments with a low dew point (ranging from -25°C to -45°C). It is commonly used in the following applications:
Process control of instrumentation
Food and pharmaceutical industries
Paint industries
Explosion-proof environments
Adsorption dryers are highly efficient and require minimal maintenance due to their simple control system.
Air Drying Process:
The desiccant material reduces the dew point of the compressed air to -25°C.
Two towers are filled with desiccant material, and each tower alternately performs air drying and regeneration.
Advantages of Komsan Industrial Group Dryers
At the air inlet section of the towers, a special alloy, stainless steel filter is installed with the following exceptional effects:
The desiccant material is protected from direct contact with water, which significantly increases its lifespan.
It distributes and reduces the speed of incoming air into the towers (by creating a large cross-sectional difference), which greatly enhances the moisture absorption capacity.
The dryers manufactured by Komsan Industrial Group are designed and built in accordance with international standards (ASME) and are certified with the ISO 9001:2008 quality management standard by SGS, the international inspection institute of Switzerland. Moreover, the high-quality desiccant used allows achieving a dew point of -25°C to -40°C.
