AIRSTAR Product Lines We Repair
Our engineers are trained on the full AIRSTAR product range. Below are the major product families we service.
Airstar Refrigerated Dryers
Compressed air dryers using refrigeration cycle to achieve -5 to +3°C dew point. Common issues include refrigerant leaks, compressor burnout, condenser fouling, and electronic expansion valve failures affecting dew point stability.
Airstar Desiccant Dryers
Adsorption-based dryers achieving ultra-low dew points (-20 to -70°C) using molecular sieve cartridges. Failure modes include desiccant saturation, heater coil burnout, solenoid drain valve sticking, and electronic purge valve control circuit faults.
Airstar Air Filtration Systems
Multi-stage compressed air filters removing particulates, oil, and water to ISO 8573-1 Class 1-6 standards. Electronic differential pressure indicators fail; filter cartridge saturation sensors malfunction; bypass solenoids become inoperative.
Airstar Condensate Drains
Electronic and pneumatic drain systems for automated condensate removal from dryers and receivers. Electronic timer drains, float-operated drains, and zero-loss drains fail due to solenoid coil burnout, timer IC failure, and float valve sticking.
Airstar Air Quality Monitoring
Dew point transmitters, pressure transducers, and air quality monitoring sensors using capacitive and optical sensing. Sensor drift, signal conditioning amplifier failure, and IP67 connector corrosion common in humid industrial environments.

Common AIRSTAR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AIRSTAR equipment arriving at our workshop.
- ✓Refrigerated dryer insufficient cooling capacity — Airstar refrigeration compressor may have failed due to motor winding burnout, or refrigerant charge has leaked from condenser copper tubing corrosion. Thermostatic expansion valve may be stuck open or closed, preventing proper refrigerant flow.
- ✓Desiccant dryer dew point rising above setpoint — Airstar desiccant cartridge has reached saturation and lost adsorption capacity after 2000-3000 operating hours. Purge air control solenoid valve may be leaking, preventing proper desiccant regeneration during idle cycles.
- ✓Electronic drain valve non-responsive — Airstar solenoid coil winding has burned out due to continuous energisation, water ingress, or AC power surge. Timer IC in drain controller may have failed, preventing periodic drain pulses.
- ✓Dew point transmitter reading erratic or frozen — Airstar capacitive dew point sensor element has accumulated condensation or dust inside sensor probe, or reference voltage supply in signal conditioning PCB has dropped. Loose DIN connector at sensor cable entry.
- ✓Filter cartridge differential pressure indicator stuck — Airstar electronic DP indicator switch contacts have welded shut or open-circuited due to water vapour condensation inside electronics housing. Mechanical linkage may be bent or corroded.
- ✓Heater coil in desiccant dryer non-functional — Airstar immersion heater element resistance wire has fractured due to thermal cycling, or power contactor has failed preventing current flow. Thermostat setpoint sensor may be defective, blocking heater activation.

Frequently Asked Questions — AIRSTAR Repairs
Do you repair Airstar equipment anywhere in India?+
Yes. Synchronics repairs the complete Airstar product range - refrigerated dryers, desiccant dryers, filters, electronic drain valves, and dew point transmitters. We offer PAN-India door pickup and return logistics from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, and all other cities. All repairs are performed at our central facility in Vadodara, Gujarat with 48-72 hour turnaround for most drying system repairs.
What is the typical dew point performance I should expect from an Airstar refrigerated dryer after repair?+
After successful repair and refrigerant recharge, Airstar refrigerated dryers should deliver -5 to +3°C pressure dew point (PDP) at rated flow under standard ambient conditions (20-35°C inlet air temperature). Synchronics tests and verifies dew point performance before return, and provides a technical report with performance curve. If performance remains below specification, we investigate compressor efficiency or expansion valve response.
How often should I replace desiccant cartridges in my Airstar ADD dryer?+
Airstar desiccant cartridges typically require replacement every 2000-3000 operating hours depending on inlet air humidity and operating temperature. If your dryer operates 24/7 in high-humidity environments (like coastal regions in India), cartridge life may reduce to 1200-1500 hours. Synchronics can supply OEM Airstar desiccant cartridges and perform hot-cartridge replacement without stopping your compressed air system.
Can Synchronics repair Airstar dew point transmitters and sensors?+
Yes. Synchronics repairs Airstar capacitive dew point transmitters (DPT series) and optical dew point sensors (OPC series). We clean sensor probe elements, replace faulty signal conditioning PCBs, recalibrate sensor output to 4-20 mA range using precision dew point reference standards, and test IP67 sealing integrity. Most sensor repairs are completed within 24 hours.
What warranty do you provide on Airstar repairs?+
Synchronics provides 12 months warranty on all component replacements and repaired assemblies for Airstar equipment. If a component fails within warranty period due to defective workmanship or component failure, we repair or replace at no charge. Warranty covers parts and labour but excludes wear-and-tear items like desiccant cartridges and filter elements.
How do I send my AIRSTAR unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a AIRSTAR drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on AIRSTAR repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your AIRSTAR unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
