At Kalyros Engineering LLP, we specialize in designing and manufacturing cutting-edge desiccant air dryers, delivering clean, dry, and high-quality compressed air for a wide range of industrial applications. Our state-of-the-art dryers are engineered to ensure optimal performance, energy efficiency, and reliability, safeguarding your equipment and processes from the detrimental effects of moisture.

What Are Desiccant Air Dryers?

Desiccant air dryers are specialized industrial equipment designed to remove moisture from compressed air through a process called adsorption. Unlike absorption, adsorption involves moisture molecules adhering to the surface of a hygroscopic material known as a desiccant. Common desiccants include silica gel, activated alumina, and molecular sieves, which ensure the delivery of dry air with a low pressure dew point (PDP) typically ranging from -20°C to -70°C.

They are essential in industries where moisture in compressed air can cause corrosion, equipment damage, product spoilage, or operational inefficiencies. By providing ultra-dry air, our dryers protect your systems and ensure consistent, high-quality performance.

How Do Desiccant Air Dryers Work?

• Adsorption Phase: Wet compressed air passes through one desiccant-filled tower, where moisture is captured and dry air exits.
• Regeneration Phase: When saturated, the system switches to the second tower while the first undergoes regeneration.
• Regeneration Process: Moisture is removed from the saturated desiccant using purge air, heat, or both.
• Continuous Operation: Towers alternate cycles, ensuring uninterrupted dry air supply.

Our dryers use advanced PLC-based controls to optimize drying and regeneration cycles for maximum efficiency.
