China 5DV Series Intelligent PM VSD Refrigerated Air Dryer - Low Energy Cost & Pressure Drop | Trusted Suppliers & Factory
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
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
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
What dew point can the Deman 5DV Series Air Dryer achieve?
The Deman 5DV Series is designed to maintain the pressure dew point within 5°C, which is lower than the 15°C typical of conventional air dryers. This difference removes over 9 kg more water per hour for a 132kW compressor, ensuring significantly drier compressed air for industrial applications.
How does the Deman 5DV Series minimize dew point fluctuations?
The 5DV Series incorporates Deman's proprietary AI control system, which continuously monitors and adapts to diverse working conditions. This intelligent control minimizes dew point fluctuations caused by load changes or environmental variations, ensuring stable and uninterrupted production performance.
What makes the Deman 5DV Series more reliable and longer-lasting than conventional air dryers?
Unlike conventional air dryers that rely on mechanical pressure switches (rated for approximately 100,000 cycles), the 5DV Series uses a fully sensor-based design for extended lifespan. It also replaces traditional copper tube-and-fin heat exchangers — which are prone to leaks and corrosion — with a reverse-flow, interlaced aluminum plate heat exchanger, reducing the risk of leaks, rust, and blockages.
How much energy can be saved with the ultra-low pressure drop design?
The Deman 5DV Series features an ultra-low pressure drop of within 0.01 MPa, compared to a typical 0.05 MPa for standard air dryers. For a 132kW compressor running 8,000 hours per year, this reduction can save over 40,000 kWh of energy annually, significantly lowering operational costs.
What refrigerant does the Deman 5DV Series use, and why is it beneficial?
The 5DV Series uses R410A, an eco-friendly and high-efficiency refrigerant. Compared to conventional refrigerants, R410A provides approximately 2% higher heat exchange efficiency, improved energy performance, and better environmental compliance, supporting both sustainability goals and operational efficiency.
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), with 18 standard models available. Selection should be based on your compressor's rated air output, operating pressure, and ambient temperature conditions.
