High-Purity Heated Adsorption Compressed Air Dryer with -40℃ Dew Point
Product Overview & Core Advantages
Our adsorption/desiccant air dryers are designed to solve moisture-related problems in compressed air systems, such as corrosion, equipment damage, and product contamination. Here’s why they stand out:
- Dual Type Options: Choose heatless adsorption air dryer for cost-effective, low-maintenance use (ideal for small to medium air flow); or micro-heated adsorption air dryer for energy efficiency (reduces regeneration air consumption by 30-50%, perfect for large-scale industrial use).
- Superior Dew Point Performance: Delivers consistent dew point of -20°C to -70°C (pressure dew point), ensuring ultra-dry compressed air for critical applications like electronics manufacturing and pharmaceutical production.
- Durable Construction: Made of high-quality carbon steel (painted/powder-coated) or 304 stainless steel (for hygienic industries), with corrosion-resistant internal components to extend service life.
- Intelligent Operation: Equipped with automatic control system, pressure gauge, and differential pressure indicator for easy monitoring and operation; supports 24/7 continuous work without manual intervention.
- Global Certification Compliance: CE, ISO certified, meeting industrial standards for food, medical, automotive, and electronics industries.
- Customizable Specifications: Adaptable to air flow from 1.0 m³/min to 210 m³/min, working pressure 0.6-1.6MPa, tailored to your specific system requirements.
Heatless vs. Micro-Heated Adsorption Air Dryer: How to Choose
Feature | Heatless Adsorption Air Dryer | Micro-heated Adsorption Air Dryer |
|---|---|---|
Regeneration Principle | Uses dry compressed air (15-20% of processed air) for regeneration without external heat source | Uses low-temperature (100-120°C) heated air for regeneration, reducing dry air consumption |
Energy Consumption | Medium (higher air consumption, no electrical heating cost) | Low (30-50% less regeneration air, minimal heating energy) |
Air Capacity | 1.0-210 m³/min | 1.0-210 m³/min |
Maintenance Complexity | Low (simple structure, no heater maintenance) | Medium (regular heater and temperature sensor check) |
Best For | Small workshops, auto repair shops, medium-scale manufacturing (cost-sensitive) | Large factories, food processing, pharmaceuticals, electronics (energy-saving demand) |

Application Scenarios
Our adsorption/desiccant air dryers (heatless & micro-heated) are widely used in industries where dry compressed air is critical:
- Food & Beverage: Prevent moisture from affecting product quality (e.g., packaging, pneumatic conveying of powders, carbonation systems).
- Pharmaceuticals: Meet strict hygiene and dryness requirements for drug production, packaging, and cleanroom air supply.
- Electronics: Protect sensitive components from moisture damage during manufacturing, assembly, and testing.
- Automotive: Ensure stable performance of pneumatic tools, painting systems, and component assembly lines.
- Manufacturing: Prevent corrosion of production equipment, pipelines, and finished products (e.g., metal processing, plastic molding).
- Medical Equipment: Supply dry air for medical devices (e.g., respirators, dental equipment) to ensure safety and reliability.
Customer Success Stories
“We installed 3 heatless adsorption air dryers in our bakery to ensure dry air for packaging. The dew point is stable at -40°C, and there’s no more moisture-related packaging issues. The maintenance is simple, and the cost is much lower than expected.” — John, Production Manager at a European Bakery
FAQs
Q1: What’s the difference between adsorption air dryer and refrigerated air dryer?
A1: Adsorption (desiccant) dryers use desiccants to absorb moisture, delivering dew point down to -70°C (suitable for low-temperature, high-dryness needs). Refrigerated dryers cool air to condense moisture, dew point only -2~10°C (suitable for general industrial use). Our adsorption dryers are better for critical applications like food, medical, and electronics.
Q2: How to choose between heatless and micro-heated adsorption air dryer?
A2: Choose heatless if your air flow is ≤20 m³/min and cost is a priority (simple structure, low maintenance). Choose micro-heated if air flow is ≥20 m³/min and you want to save energy (reduces regeneration air consumption significantly).
Q3: Can the dryer be customized for 304 stainless steel material?
A3: Yes! We offer 304/316 stainless steel options for food, medical, and pharmaceutical industries to meet hygiene and corrosion resistance requirements.
Q4: What’s the lead time for custom adsorption air dryers?
A4: Standard models are in stock (lead time 3-7 days). Custom models (special air flow, material, or certification) take 2-4 weeks.
