ARS Product Lines We Repair
Our engineers are trained on the full ARS product range. Below are the major product families we service.
ARS Screw Compressor Control Units
ARS compressor drive systems featuring integrated capacity control, oil management, and thermal regulation. Common faults include solenoid valve failures, pressure transducer drift, and microprocessor lockups causing compressor shutdown or hunting.
ARS Chiller Master Controllers
Industrial chiller control platforms combining temperature sensing, compressor modulation, and safety interlocks. Typical failures involve sensor calibration loss, relay contact degradation, and firmware corruption leading to temperature overshoot or undershoot.
ARS Pressure and Temperature Transducers
High-accuracy industrial sensors for refrigerant pressure monitoring and discharge temperature measurement. Common issues include sensor drift, 4-20mA output failure, connector corrosion in humid environments, and calibration loss after thermal cycling.
ARS Oil Management Electronics
Automated oil level and quality monitoring systems preventing compressor damage from lubrication failure. Frequent repairs address float switch malfunction, electrode degradation in oil condition sensors, and display module failures.
ARS Safety and Interlock Systems
Protective relay circuits and safety logic modules preventing unsafe compressor operation. Common faults involve contactor coil burnout, auxiliary contact welding, and logic board component failure during high-pressure events.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common ARS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ARS equipment arriving at our workshop.
- ✓ARS controller loses refrigerant pressure reading signal — Pressure transducer 4-20mA output cable shorted or sensor calibration drifted due to thermal cycling stress common in Indian summers. ARS transducers are susceptible to connector corrosion in humid coastal regions.
- ✓ARS compressor capacity control valve sticks in fixed position — Solenoid valve coil burnout or spool stiction from refrigerant varnish deposits — especially in systems running continuously in high ambient temperatures typical of Indian summer operations. Mineral oil residues accumulate on valve internals.
- ✓ARS chiller control board displays E04 or E08 fault codes — E04 indicates temperature sensor failure or loose sensor connection; E08 signals high-pressure safety shutdown. Both occur when control board PCB tracks develop cold-solder joints or sensor cables vibrate loose in industrial environments with heavy equipment nearby.
- ✓ARS oil level sensor gives false low-level alarms — Float switch contact points stick or electrode rod corrodes in oil separator. Mineral oil degradation products coat electrode, creating high resistance. Common in systems operating 24/7 in Indian textile, food processing, and pharmaceutical plants without adequate oil change intervals.
- ✓ARS main microprocessor module hangs or reboots continuously — EEPROM memory corruption from power supply voltage spikes or software firmware incompatibility after partial updates. Indian industrial power supplies often deliver unstable voltage during monsoon season, damaging processor memory.
- ✓ARS relay contactor chatters or fails to hold compressor motor starter — Contactor coil voltage drops below pickup threshold due to loose terminal connections or degraded power supply output. Auxiliary contact erosion from inrush current spikes prevents mechanical latch engagement in heavy-duty Indian manufacturing environments.

Frequently Asked Questions — ARS Repairs
Do you repair ARS equipment anywhere in India?+
Yes. Synchronics repairs the complete ARS refrigeration control system portfolio — compressor controllers, chiller master units, pressure and temperature transducers, oil management electronics, and safety interlocks. We offer PAN India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all industrial cities. Our central repair facility in Vadodara, Gujarat ensures rapid turnaround with one-year warranty on all ARS repairs.
How long does ARS compressor controller repair typically take?+
Standard ARS control board repair including PCB diagnostics, component replacement, and calibration takes 5-7 working days. Complex failures requiring microprocessor reprogramming or solenoid valve replacement extend to 10-12 days. Synchronics offers express 48-hour repair for critical units affecting production, with premium pricing. We maintain loaner units to keep your chiller running while we service your controller.
What is the cost advantage of repairing versus replacing an ARS chiller control system?+
ARS chiller controller replacement costs INR 1.5-2.5 lakhs including new unit and installation. Synchronics repair averages INR 18,000-35,000 depending on component damage, delivering 80-90% cost savings. Most ARS controllers remain fully serviceable for 10-15 years when component-level repair is performed. We recommend repair for systems less than 8 years old, especially in India where downtime costs exceed parts costs.
Can Synchronics recalibrate ARS pressure and temperature sensors to match factory specifications?+
Yes. Synchronics has certified test equipment capable of recalibrating ARS PT-500 series sensors and custom transducer modules to factory ±0.5% accuracy. We provide full calibration certificates traceable to ISI standards for pharmaceutical and food industry compliance. Sensor recalibration costs INR 3,500-6,500 per unit — significantly lower than replacement at INR 25,000+ — and restores long-term accuracy for systems in coastal or humid regions where sensor drift accelerates.
Does Synchronics stock genuine ARS spare parts or repair components?+
Synchronics maintains inventory of high-failure ARS components including solenoid valve coils, float switches, relay contactors, pressure transducers, and PCB capacitor/resistor kits. For obsolete ARS parts, we source directly from Japanese distributors within 10-14 days. We do not use non-OEM substitutes — all repairs use genuine ARS or equivalent rated components. Each repair includes parts warranty matching the labour warranty period.
How do I send my ARS 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 ARS 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 ARS 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 ARS 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.
