5DV Series Intelligent PM VSD Refrigerated Air Dryer from China Suppliers & Factory - Energy Efficient and Low Pressure Solutions
Product Highlight
Low Dew Point
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
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
Low Pressure Drop
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
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 is the dew point performance of the Deman 5DV Series air dryer?The Deman 5DV Series maintains a pressure dew point within 5°C, which is significantly lower than the industry standard of 15°C. This ensures that for every 1 m³ of compressed air at 1 MPa, over 5.8 g less water remains in the air, delivering consistently drier and cleaner compressed air for your production processes.
-
Q How does the Deman 5DV Series reduce energy consumption compared to conventional air dryers?The 5DV Series features an ultra-low pressure drop of within 0.01 MPa, compared to the typical 0.05 MPa of conventional air dryers. For a 132kW compressor running 8,000 hours per year, this alone saves over 40,000 kWh annually. Additionally, the DCBSMAT variable frequency system, eco-friendly R410A refrigerant, and superior heat recycle design further reduce overall energy consumption.
-
Q What makes the heat exchanger in the Deman 5DV Series superior to conventional designs?Unlike conventional copper tube-and-fin heat exchangers that are prone to leaks and corrosion, the Deman 5DV Series uses a reverse-flow, interlaced aluminum plate heat exchanger with a wide-channel counter flow design. This reduces the risk of leaks, rust, and blockages, while also enabling lower pressure loss, more stable dew point control, and more efficient air-water separation.
-
Q How does the AI control system help maintain stable dew point performance?Deman's proprietary AI control system continuously monitors and adapts to diverse operating conditions in real time. This minimizes dew point fluctuations that typically occur due to changes in inlet air temperature, load, or ambient environment, ensuring stable and uninterrupted production performance even in demanding or complex industrial conditions.
-
Q What refrigerant does the Deman 5DV Series use, and why is it eco-friendly?The Deman 5DV Series uses R410A refrigerant, which is a more environmentally responsible choice compared to older refrigerants such as R22. R410A provides 2% higher heat exchange efficiency, improved energy performance, and significantly lower environmental impact, meeting modern eco-friendly standards and helping companies reduce their carbon footprint.
-
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 air flow range from 2.6 m³/min (model 5DV-2.6 A) up to 250 m³/min (model 5DV-250 A), making it suitable for small workshops to large industrial facilities. To select the right model, match the air dryer's rated air flow to the maximum output of your compressor system, and consider inlet/outlet diameter, available space (dimensions), and required power supply when making your selection.
