Compressed Air Dryers
Moisture in compressed air is the leading cause of equipment corrosion, product contamination, and pneumatic system failure. Sangawar Pneumatics designs and manufactures a complete range of compressed air dryers — from heatless regenerative and heated low purge types to ultra-dry -70°C dew point systems — engineered for continuous industrial operation. Built at our Vasai facility and trusted by organisations including ISRO and NPCIL, our dryers are custom-sized to your flow rate, pressure, and dew point requirements. Ideal for pharmaceutical, food processing, automotive, electronics, and heavy manufacturing industries.
Heatless Regenerative Air Dryer
Delivers consistently dry compressed air using Pressure Swing Adsorption (PSA) technology — no external heating required, minimal moving parts, and automatic tower switching for uninterrupted operation.
Features:
- Twin tower PSA design for continuous drying
- Automatic tower switching with PLC control
- Desiccant beds sized to your exact flow rate
Advantages:
- Low capital investment with fast ROI
- Simple operation — minimal operator intervention
- Easy on-site maintenance with accessible desiccant beds
Heated Low Purge Air Dryer
Energy-efficient compressed air dryer that uses an external heater during regeneration to significantly reduce purge air consumption — ideal for large-capacity installations where operating cost matters.
Features:
- External heater regeneration reduces purge air by up to 40%
- PLC-based automatic control with fault indication
- Suitable for high-flow industrial compressed air systems
Advantages:
- Significantly lower energy and operating costs vs. heatless type
- Reduced compressor load — protects upstream equipment
- Designed for continuous 24/7 industrial operation
No Purge Loss Air Dryer
Advanced blower-regenerated compressed air dryer that achieves zero purge air loss — the highest efficiency drying solution available for industries where every cubic metre of compressed air has a cost.
Features:
- Zero compressed air purge loss during regeneration
- Blower and heater combined regeneration system
- High-efficiency desiccant bed with long service life
Advantages:
- Maximum energy savings — lowest lifecycle operating cost
- Reduces compressor running hours and power consumption
- Environmentally responsible — zero vented air waste
Low Dew Point Air Dryer (-70°C)
Ultra-dry compressed air dryer achieving dew points as low as -70°C — engineered for critical applications in pharmaceuticals, electronics, defence, and laboratory environments where any trace of moisture is unacceptable.
Features:
- Dew point down to -70°C for extreme dryness
- Molecular sieve desiccant for superior moisture adsorption
- High-precision dew point monitoring and control
Advantages:
- Protects sensitive processes from moisture damage
- Ideal for pharmaceutical, electronics, and defence applications
- High reliability with long desiccant service intervals
Refrigerated Compressed Air Dryer
Cost-effective compressed air dryer that removes bulk moisture by cooling air to a safe dew point — the most widely used dryer for general industrial applications where a pressure dew point of +3°C to +10°C is acceptable.
Features:
- Refrigeration-based air cooling and moisture separation
- Automatic electronic drain for continuous condensate removal
- Compact, skid-mounted design for easy installation
Advantages:
- Low purchase and installation cost
- Minimal maintenance — no desiccant replacement required
- Reliable continuous operation for general industrial use
