China Suppliers Factory 5DV Series Intelligent PM VSD Refrigerated Air Dryer for Low Energy and Moisture Control
Product Highlight
Low Dew Point KEY FEATURE
For every 1 m³ of compressed air at 1 MPa, the water content is 5.8 g higher at a 15°C dew point than at a 5°C dew point. A 132kW compressor produces 26 m³/min, and a lower dew point removes over 9 kg more water per hour, ensuring drier air. The Deman 5DV Series keeps the dew point within 5°C.
Low Fluctuation AI CONTROL
Deman's unique AI control system takes into account diverse working conditions, enabling the air dryer to operate reliably even in complex environments. It minimizes dew point fluctuations caused by varying conditions and ensures stable, uninterrupted production for customers.
Low Failure Rate RELIABLE
Conventional air dryers use mechanical pressure switches, which typically last around 100,000 cycles. In contrast, the Deman 5DV Series employs a fully sensor-based design, significantly extending its lifespan.
Conventional air dryers use copper tube-and-fin heat exchangers which are prone to leaks and corrosion. The Deman 5DV Series utilizes a reverse-flow, interlaced aluminum plate heat exchanger, reducing the risk of leaks, rust, and blockages.
Low Pressure Drop ENERGY SAVING
A typical air dryer causes a 0.05 MPa pressure drop, resulting in over 40,000 kWh of energy consumption annually for a 132kW compressor (7% more energy cost from the air compressor for every 0.1MPa increase in exhaust air pressure, assuming service factor 1.15, and 8,000 hours). The Deman 5DV Series Air Dryer features an ultra-low pressure drop within 0.01 MPa, significantly reducing energy consumption and operational costs.
Low Energy Cost VSD SYSTEM
Superior inlet-outlet air heat recycle delivers lower energy consumption for air processing. More efficient refrigerants for enhanced performance. Most importantly, the Deman—DCBSMAT variable frequency system ensures intelligent energy-saving control.

Frequently Asked Questions
Q
What dew point can the Deman 5DV Series Air Dryer achieve?
The Deman 5DV Series maintains a pressure dew point within 5°C, which is significantly lower than conventional refrigerated air dryers. This results in drier compressed air and removes over 9 kg more water per hour compared to systems operating at a 15°C dew point, when paired with a 132kW compressor producing 26 m³/min.
Q
How does the Deman 5DV Series reduce energy consumption compared to conventional air dryers?
The 5DV Series achieves an ultra-low pressure drop within 0.01 MPa, compared to the typical 0.05 MPa of conventional dryers. This alone saves over 40,000 kWh annually for a 132kW compressor. Additionally, the DCBSMAT variable frequency (VSD) system, efficient R410A refrigerant, and superior heat recycle design all contribute to significantly reduced operational energy costs.
Q
What makes the Deman 5DV Series more reliable than traditional air dryers?
The 5DV Series replaces traditional mechanical pressure switches—limited to around 100,000 cycles—with a fully sensor-based design for a longer service life. It also uses a reverse-flow, interlaced aluminum plate heat exchanger instead of copper tube-and-fin designs, greatly reducing the risk of leaks, corrosion, and blockages for sustained, trouble-free operation.
Q
What refrigerant does the Deman 5DV Series use, and why is it beneficial?
The Deman 5DV Series uses R410A, an eco-friendly refrigerant that provides approximately 2% higher heat exchange efficiency compared to older refrigerants. R410A also delivers improved energy performance and reduces environmental impact, supporting both sustainability goals and regulatory compliance.
Q
How does the AI control system help stabilize dew point performance?
Deman's proprietary AI control system continuously monitors and adapts to diverse and changing working conditions. It actively compensates for load variations, ambient temperature changes, and other environmental factors, minimizing dew point fluctuations and ensuring stable, uninterrupted production output for customers at all times.
Q
What air flow range does the Deman 5DV Series cover, and how do I select the right model?
The Deman 5DV Series covers a wide range from 2.6 m³/min (Model 5DV-2.6 A) up to 250 m³/min (Model 5DV-250 A), with 18 models available to suit various application scales. To select the correct model, match the rated air flow to your compressor's output, and consider inlet/outlet diameter and available installation dimensions as listed in the Technical Parameter table above.
