ECODRAIR Series Refrigerant Compressed Air Dryers
The SANPAR ECODRAIR Series is specifically designed to deliver filtered compressed air by removing moisture, oil vapors, and dust particles that often damage pneumatic tools, cylinders, and production lines. By maintaining a controlled dew point and ensuring stable operation, the ECODRAIR Series minimizes downtime, reduces product rejection, and significantly lowers maintenance costs. Unlike conventional dryers, SANPAR’s industrial air dryers in India are compact, eco-friendly, and equipped with digital monitoring systems for greater reliability in demanding environments.
Why Compressed Air Treatment Matters
Compressed air delivered directly from an air compressor contains moisture, dust, and oil vapors. Without treatment, these contaminants can damage pneumatic accessories, bearings, valves, and even sensitive measuring equipment. The consequences include:
- Increased machinery downtime
- Higher production losses
- Greater risk of product rejection
- Escalating maintenance costs
By integrating the ECODRAIR refrigerant compressed air dryer into industrial setups, companies ensure a stable, clean, and dry air supply that enhances operational efficiency while safeguarding critical equipment.
Intelligent Hot Gas Bypass Valve and Capillary Tube
The ECODRAIR Series features an advanced hot gas bypass valve and a capillary tube that optimize the refrigeration cycle, ensuring consistent performance across varying loads.
- Hot Gas Bypass Valve prevents freezing in the evaporator during low-load conditions, protecting the system and maintaining continuous operation.
- Capillary Tube ensures precise expansion of refrigerant, optimizing energy efficiency and eliminating dew point fluctuations.
These innovations provide greater stability and reliability in industrial automation air supply systems, especially under variable production demands.
Precision Dew Point and Pressure Monitoring
Maintaining the correct dew point is critical for protecting pneumatic tools and sensitive production processes.
- The digital dew point indicator provides real-time monitoring of outlet air conditions, ensuring accurate control over air quality.
- Pressure drop across the system is kept minimal (≤0.15 bar), ensuring efficiency and reduced energy loss.
