Air Dryers

A desiccant air dryer is an essential tool for removing moisture and impurities from compressed air systems to prevent corrosion and contamination. Different types of desiccants are used in desiccant air dryers to efficiently absorb moisture and ensure the quality of compressed air. Some common types of desiccants used in desiccant air dryers include silica, activated charcoal, calcium chloride, calcium sulfate, and aluminosilicate minerals (zeolites). These desiccants have specific properties that make them effective in adsorbing moisture and maintaining optimal humidity levels in compressed air systems. Choosing the right desiccant for a desiccant air dryer depends on the specific requirements of the application and the desired level of moisture removal.

 refrigerated air dryer is a crucial component in compressed air systems, designed to efficiently remove moisture from the compressed air to prevent corrosion and damage to equipment. By utilizing air-to-air and air-to-refrigerant heat exchangers, these dryers effectively condense water vapor within the air, ensuring that the compressed air remains dry and clean. This process is essential for maintaining the quality and integrity of the entire compressed air system, safeguarding equipment and machinery that rely on compressed air for optimal performance. Refrigerant dryers are widely recognized for their reliability and efficiency, making them the preferred choice for various industrial applications where moisture control is paramount.

When to use a refrigerated air dryer?

Refrigerated air dryers are the ideal solution if your operations meet the following conditions:

• The ambient temperature is less than 50°C/122°F,
• The main goal is to prevent condensation,
• And the required pressure dew point is around 3°C-4°C/37°F-39°F.
• The benefits of refrigerated compressed air dryers

Refrigerated air dryers have a number of compelling benefits:

• Low initial cost
• High reliability, easy to use and maintain
• Extends the life of your compressor
• Energy savings

A refrigerated air dryer is the most commonly used type of compressed air dryer for most plant applications. It is used for drying plant air and other utility gases like seal gas, hydrogen gas for generator cooling, nitrogen gas drying, etc. This type of dryer ensures a dew point of (+2) Deg. C. at line pressure (equivalent to -22 Deg. C. at atmospheric pressure), which is widely accepted in various industries. Refrigerated air dryers are ideal for applications such as fly ash conveying, cement conveying, powder conveying, pneumatic conveying of materials, dense phase conveying, lean phase conveying, seal gas drying, general plant air drying, hydrogen gas drying for generator cooling, and operation of pneumatic tools.
