Industrial Air Dryers & Pneumatics

Zero Moisture. Maximum Pneumatic Reliability.

Moisture in compressed air lines causes rust, pneumatic valve failure, and ruined end-products. We provide specialized maintenance for refrigerated and desiccant air dryers, ensuring exact dew-point control for sensitive manufacturing processes.

Technical Capabilities
  • Refrigerant Circuit Leak Testing & Recharging
  • Hot Gas Bypass Valve Calibration
  • Auto-Drain Valve Overhauls
  • Dew Point Sensor Verification
Industrial SLA

We operate across Chakan, Ranjangaon, and Wagholi MIDCs with 4-hour response times for critical manufacturing plant breakdowns.

Fault Code Library

Common Industrial Air Dryers & Pneumatics error codes and our diagnostic response protocols.

Atlas Copco

High Dew Point Alarm

Evaporator temperature is too high

Action:Check condenser fan operation and ambient temperature.

Compressor Overload

High head pressure or electrical fault

Action:Clean condenser fins and verify amp draw.

Preventive Maintenance

Our standardized operating procedures (SOPs) for routine maintenance.

  1. Verify refrigerant suction pressure matches the target dew point (usually 3°C to 5°C).
  2. Clean or replace the auto-drain strainer.
  3. Check the operation of the hot gas bypass valve under no-load conditions.
  4. Measure pressure drop across pre and post filters.
Case Study Highlight

Auto-Component Factory, Chakan

Eliminated Pneumatic Rust

Overhauled a failing 500 CFM refrigerated dryer, resolving intermittent high dew point alarms and saving CNC machine valves from moisture damage.

Frequently Asked Questions

Q. What is the ideal dew point for a refrigerated air dryer?

The standard pressure dew point for refrigerated dryers is typically +3°C (37°F). Anything higher indicates a loss of cooling capacity.

Q. Why is water still coming out of my air lines?

Either the dryer's auto-drain is clogged, the bypass valve is open, or the dryer is undersized for the current compressor output.
