AERZEN Product Lines We Repair
Our engineers are trained on the full AERZEN product range. Below are the major product families we service.
VM / VSE Screw Compressor Series
Core rotary screw compressors with integrated motor starters and pressure regulators. Common faults: pressure switch failures, unloader valve stiction, motor soft-starter malfunction. Repair involves electronics diagnostics and replacement of control boards.
Delta Blower Series
Single and two-stage rotary blowers for aeration, pneumatic conveying, and vacuum. Typical issues: VSD communication faults, pressure transducer drift, motor phase loss detection failures. Requires calibration and sensor replacement.
Stratos Blower Series
High-efficiency screw blowers with integral variable speed drives. Common repair needs: VSD firmware updates, pressure regulator electronics failure, motor bearing wear detection faults. Electronics-heavy design requires specialist diagnostics.
AeroSmart Control Module Series
Networked compressor management system for multi-unit compressed air stations. Faults include Modbus/profibus slave card failure, power supply module burnout, logic board corrosion. Common in Indian textile mills and food plants.
Cooler Control and Thermostatic Valve Electronics
Temperature regulation electronics for Aerzen air-cooled and water-cooled systems. Typical failures: thermistor sensor malfunction, temperature regulation board short-circuit, fan contactor failure. Critical for plant uptime in tropical Indian climate.

Common AERZEN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AERZEN equipment arriving at our workshop.
- ✓Pressure switch malfunction causes nuisance shutdowns — Aerzen pressure transducers and mechanical switches suffer from dust ingress and moisture condensation in humid Indian industrial environments. Electronic pressure switches suffer from corrosion and calibration drift after 3-5 years of operation.
- ✓VSD communication error - loss of speed control signal — Aerzen Delta and Stratos blowers with integrated VSDs fail when Modbus or profibus communication wiring degrades. High moisture and vibration in Indian pump stations cause connector corrosion and signal cable faults.
- ✓Soft-starter tripping under full load condition — Aerzen motor soft-starters in VM and VSE series overheat due to inadequate thermal dissipation in Indian summer conditions. Control board electrolytic capacitors fail prematurely in compressor rooms exceeding 45C ambient temperature.
- ✓Unloader valve remains stuck in closed position — Aerzen unloader solenoid coils lose continuity after extended operation. Electronics failure in the unloader control circuit prevents solenoid energisation. Common in food processing plants with hygiene washdown water ingress.
- ✓AeroSmart network module offline - compressor invisible in management system — Aerzen AeroSmart Modbus/profibus cards suffer from firmware corruption, corrupted database on SD card, and power supply module failure. Common in large textile mills and pharma plants using centralised compressed air monitoring.
- ✓Thermostatic expansion valve electronics not regulating cooler temperature — Aerzen cooler control boards experience thermistor sensor failure, relay contact welding, and power supply burnout. Leads to compressor overheating and automatic shutdown in Indian monsoon season high-humidity conditions.

Frequently Asked Questions — AERZEN Repairs
Do you repair Aerzen compressors and blowers anywhere in India?+
Yes. Synchronics has factory authorisation to repair all Aerzen rotary screw compressors, blowers, and control systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Vadodara, and 50+ other cities. Fast-track diagnosis at our 10,000 sq.ft. service facility in Gujarat with same-day reporting.
My Aerzen VM compressor keeps tripping on pressure cutout. What could be wrong?+
Pressure transducer calibration drift or mechanical pressure switch wear are the most common causes in Aerzen VM series after 4-5 years. Moisture ingress from humid Indian air can also corrupt the electronic pressure sensing board. Synchronics tests your pressure circuit with certified gauges, recalibrates the transducer, and replaces any failed switch modules. We offer 12-month warranty on pressure control repairs.
We operate a Delta Blower station with Modbus networking. The unit keeps losing network connection. Can you help?+
Delta Blower profibus slave cards frequently fail due to connector corrosion in tropical environments. Synchronics diagnoses the Modbus communication layer, tests and replaces the slave card, and upgrades connectors with sealed military-spec alternatives rated for moisture. We stock genuine Aerzen spare cards and offer field integration support for Indian plant networks.
How long does an Aerzen repair typically take?+
Standard electronics repair — 3 to 5 working days. Complex VSD or AeroSmart network module repairs — 5 to 7 days. We offer express turnaround (48 hours) for critical plant equipment with nominal rush charge. All repairs include full functional testing and pressure/load cycle validation before dispatch.
Do you provide preventive maintenance for Aerzen compressor control systems?+
Yes. Synchronics offers annual and bi-annual preventive maintenance contracts covering thermistor sensor replacement, capacitor health monitoring, relay contact cleaning, and firmware updates for Aerzen equipment across India. Suitable for food, pharma, textile, and water treatment plants. Maintenance visits scheduled during plant maintenance windows.
How do I send my AERZEN 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 AERZEN 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 AERZEN 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 AERZEN 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.
