AIR PRODUCTS Product Lines We Repair
Our engineers are trained on the full AIR PRODUCTS product range. Below are the major product families we service.
OnSite and Merchant Gas Generation Systems
Modular on-site nitrogen and oxygen generation units with integrated pressure control, flow measurement, and gas purity monitoring. Common issues include compressor sensor failures, pressure transducer drift, gas quality analyzer calibration loss, and PLC module faults affecting gas output regulation.
Cryogenic Liquid Supply and Vaporization Systems
Liquid oxygen, nitrogen, and argon storage and regasification equipment with precise temperature and pressure regulation electronics. Frequent faults include liquid level sensor malfunction, cryogenic pressure regulator drift, vaporizer control board failures, and temperature transmitter signal loss at sub-zero conditions.
Gas Flow Control and Metering Instrumentation
Mass flow controllers, pressure regulators, check valves, and integrated manifold systems for precise gas distribution in semiconductor, aerospace, and pharmaceutical manufacturing.

Gas Purity and Safety Monitoring Systems
Oxygen purity analyzers, moisture monitors, particle counters, and gas chromatography-based quality assurance systems for critical applications. Repair focuses on analyzer sensor failures, calibration errors, signal conditioning board faults, and display unit malfunctions affecting compliance with pharmaceutical and semiconductor specifications.
Automated Gas Distribution and SCADA Networks
Distributed control systems, HMI panels, and networked gas flow regulators for plant-wide gas management in refineries, steel mills, and chemical processors.

Common AIR PRODUCTS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AIR PRODUCTS equipment arriving at our workshop.
- ✓Pressure transducer signal loss or drift — Air Products pressure transducers exposed to vibration, thermal cycling, and contaminated gas streams in harsh industrial environments. Electrical connectors corrode in humid conditions; piezoelectric elements degrade under sustained overpressure or cryogenic exposure, causing calibration shift or complete signal failure.
- ✓Cryogenic liquid level sensor malfunction — Air Products liquid oxygen and nitrogen level sensors freeze-up or suffer capacitive drift due to moisture ingress into probe assemblies. Direct immersion probes accumulate ice crystals; radar-based sensors lose calibration when condensate films form on antenna surfaces, especially in high-humidity Indian climates.
- ✓Gas purity analyzer sensor contamination or calibration loss — Air Products oxygen purity and moisture analyzers in refineries, pharmaceutical plants, and semiconductor facilities accumulate dust, oil mist, and process gas byproducts on sensing electrodes. Regular recalibration intervals are missed, or sensor tubes develop micro-leaks allowing ambient air to dilute measurement accuracy.
- ✓PLC and HMI communication failures in gas distribution networks — Air Products networked gas control systems in large refineries and steel plants suffer Ethernet and fieldbus cable damage from thermal stress, rodent intrusion, or improper grounding. PLC I/O modules develop cold-solder joints; HMI power supplies fail under load; gateway modules lose firmware synchronization, causing loss of real-time gas flow data and safety interlocks.
- ✓Mass flow controller sensor response lag or zero-point drift — Air Products mass flow controllers in semiconductor and pharmaceutical clean-room gas delivery systems experience thermal lag due to inadequate heater calibration, or sensor offset drifts from micro-particle accumulation on thermal sensing elements. Humidity and temperature swings in Indian monsoon climates worsen zero-point instability.
- ✓Safety shutoff solenoid valve coil failure or stiction — Air Products emergency shutoff solenoids in hazardous gas environments experience coil insulation breakdown due to sustained pressure spikes, moisture ingress, or thermal aging. Valve spools stick due to corrosion or varnish formation from mineral deposits in unfiltered gas lines, preventing reliable emergency isolation.

Frequently Asked Questions — AIR PRODUCTS Repairs
Do you repair Air Products equipment anywhere in India?+
Yes. Synchronics repairs the complete Air Products portfolio — gas generation units, cryogenic systems, flow controllers, purity analyzers, PLC control modules, and HMI panels. We offer door-to-door pickup from Mumbai, Delhi, Bangalore, Hyderabad, Pune, Chennai, Ahmedabad, Kolkata, and all tier-1 Indian cities. All repairs are performed at our ISO 9001-certified Vadodara facility with turnaround times typically 10-15 working days.
Can Synchronics recalibrate Air Products gas purity analyzers and mass flow controllers for pharmaceutical compliance?+
Yes. Synchronics holds calibration certificates for oxygen purity analysis (0-100% O2), moisture measurement (0-1000 ppm), and mass flow standards. We recalibrate Air Products analyzers and controllers per ISO 9001 and supply full traceability documentation (NIST-linked). All sensors are re-tested in clean-room conditions to pharma GMP standards. Typical calibration cost is 30-40% less than factory service.
What is the typical cost and turnaround for repairing an Air Products cryogenic liquid level sensor?+
Air Products liquid oxygen and nitrogen level probes typically cost INR 18,000-35,000 to repair or replace, depending on sensor type (capacitive vs. radar). Synchronics carries emergency stock of level sensor cartridges. Turnaround is 5-7 working days from receipt. We also supply refurbished sensors at 40-50% cost reduction if original units are uneconomical to repair.
Does Synchronics repair Air Products PLC modules and gas distribution control systems in steel plants?+
Yes. Synchronics has repaired Air Products distributed gas control systems in leading Indian steel mills (JSW, Tata Steel, ArcelorMittal) and refineries. We diagnose and repair PLC input/output card failures, Ethernet communication modules, pressure transmitter interfaces, and safety interlock logic boards. We test repaired systems on test benches to verify gas flow regulation accuracy before returning equipment. Typical steel plant gas control panel repair: INR 45,000-80,000 with 2-3 week turnaround.
Can you supply spare parts for Air Products gas equipment or only repair existing units?+
Synchronics primarily offers repair and calibration services. For spare parts, we source OEM Air Products components through authorized distributors. However, for obsolete or long-lead-time components, we can recommend equivalent industrial-grade alternatives (pressure transducers, solenoid coils, sensor cartridges) that are compatible and cost-effective. Contact our technical team with your Air Products model number for availability and lead times.
How do I send my AIR PRODUCTS 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 AIR PRODUCTS 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 AIR PRODUCTS 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 AIR PRODUCTS 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.
