About Heatless Dryer

Heatless Dryers

Heatless Dryers are functional as the pressure swing adsorbers engineered to recollect the heat of adsorption in the drying process. The stored adsorption heat can be spent during the process of regeneration and enables the removal of moisture. These are beneficial in removing the moisture. The said drying units are highly ideal for the applications of high-quality oil free air treatment. Heatless Dryers can be made to work pneumatically for remote, hazardous and mobile locations.

Advanced PSA Drying Technology

Employing twin tower Pressure Swing Adsorption, the heatless dryer efficiently removes moisture from compressed air streams, delivering consistent dew points and extended desiccant life. The automated cycle ensures uniform drying and regeneration, optimizing process stability for industrial applications.

Reliable Performance and Easy Installation

Built for durability with mild steel or stainless steel construction and a corrosion-resistant finish, this dryer is designed for vertical, skid-mounted setup, simplifying on-site integration. Standard BSP/flanged pipe connections offer flexible interfacing, suitable for a wide range of operational environments.

Energy-Efficient Operation

Featuring heatless desiccant regeneration through purge air, the system consumes minimal power-primarily for the PLC controls and solenoid valves. With power consumption typically below 100 W, it provides significant energy savings over traditional heated dryers, benefiting operating costs.

FAQ's of Heatless Dryer:

Q: How does the heatless dryer achieve moisture removal from compressed air?

A: The unit uses twin tower Pressure Swing Adsorption (PSA) technology. Compressed air passes through desiccant beds that absorb moisture, and the system automatically switches towers in a 10-minute cycle, using a portion of dry air (purge) for regeneration without external heat.

Q: What is the main advantage of using purge air for desiccant regeneration?

A: Purge air regeneration requires no additional heat source, simplifying operation, reducing energy consumption, and minimizing maintenance compared to heated types. This approach sustains desiccant efficiency and ensures a stable dew point.

Q: When should this heatless dryer be used in an industrial setting?

A: It is ideal for any process requiring extremely dry compressed air, such as food, pharmaceutical, electronics, or any application sensitive to moisture, especially where dew points down to -40C are required.

Q: Where is the typical installation location for the heatless dryer?

A: The dryer is installed vertically and skid-mounted near the compressed air source in a facility. Its compact footprint allows integration into existing systems in manufacturing, processing, or utility areas.

Q: What is the process for connecting this dryer to an existing air system?

A: You can connect the dryer using BSP or flanged pipe connections as per your model's specifications. Installation is streamlined due to vertical mounting and common inlet/outlet arrangements.

Q: How does the automatic/PLC control benefit usage?

A: The PLC-based controls automate the drying and regeneration cycles, ensuring consistent performance, minimal user intervention, and system diagnostics. This enhances reliability and simplifies operation and maintenance scheduling.

Q: What are the primary benefits of choosing this heatless dryer?

A: Key benefits include low energy requirement, reliable operation in demanding environments, consistent dew point achievement, robust build quality, and ease of installation and maintenance. It is well-suited for distributorship, export, manufacturing, and industrial supply across India.
