We have restored CTI equipment for Indian fabs, ISRO centres, and research institutions—ensuring zero downtime for vacuum-dependent operations. We repair all CTI industrial electronics and offer PAN-India service.
Expert cryogenic pump and helium compressor repair across all CTI turbomolecular product lines.
CTI Product Lines We Repair
Our engineers are trained on the full CTI product range. Below are the major product families we service.
CTI Turbomolecular Pumps (TMP)
High-speed turbomolecular pumps used in semiconductor processing, analytical instruments, and space simulation. Common issues include magnetic bearing drift, rotor imbalance, seal degradation, and control electronics failure causing shutdown codes.
CTI Helium Compressor Systems (Cryo-Torr)
Closed-loop helium refrigeration compressors for cryogenic cooling in dilution refrigerators and low-temperature research. Typical faults include compressor motor failure, cold head blockage, solenoid valve malfunction, and pressure regulator offset.
CTI Control Electronics and Power Supplies
Dedicated controllers, power supplies, and frequency converters for pump operation and thermal management. Repair focuses on MOSFET failure, thermal runaway, connector corrosion, and firmware corruption in older units.
CTI Magnetic Bearing Electronics
Precision magnetic bearing control boards that levitate turbomolecular pump rotors without mechanical contact. Failures include bearing sensor drift, amplifier saturation, and loss of levitation pressure—critical for pump integrity.
CTI Pump Interface and Isolation Valves
Solenoid-operated isolation valves, gas lines, and instrumentation interfaces. Common faults include valve coil burnout, diaphragm rupture, pressure gauge failure, and thermal sensor malfunction.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common CTI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CTI equipment arriving at our workshop.
- ✓Turbomolecular pump fails to reach full speed — Magnetic bearing drift or rotor imbalance due to thermal cycling or bearing degradation in CTI TMPs. The position feedback signal drifts outside tolerance, causing the control electronics to limit motor frequency, preventing full 60,000+ RPM operation.
- ✓Helium compressor low discharge pressure or no flow — CTI helium compressor cold head internal blockage (ice formation or debris), compressor motor stall, or check valve failure. Pressure gauge reads near zero despite motor running, indicating compression cycle failure.
- ✓Control electronics display error codes or pump shutdown — CTI control board MOSFET burnout, thermal sensor open/short circuit, or firmware corruption from power loss. Pump may show 'Over Temp' or 'Speed Fault' codes before abrupt shutdown.
- ✓Solenoid isolation valve stuck or not responding — CTI solenoid coil burnout due to voltage transient, diaphragm rupture from repeated pressure cycling, or armature corrosion preventing valve closure. Pump cannot be isolated for maintenance.
- ✓Magnetic bearing electronics unstable or intermittent levitation — Position feedback sensor air gap misalignment, amplifier thermal drift, or bearing coil shorts in CTI pump magnetic bearing module. Rotor may intermittently contact mechanical stop, causing vibration and noise.
- ✓Cryogenic system thermal performance degraded — CTI helium compressor dirty condenser coils, inadequate cooling water flow, thermal siphon line blockage, or expansion valve erosion reducing cold head cooling capacity and equilibrium temperature.

Frequently Asked Questions — CTI Repairs
Do you repair CTI equipment anywhere in India?+
Yes. Synchronics repairs the full CTI product range—turbomolecular pumps, helium compressors, magnetic bearing electronics, control boards, and isolation valve systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other cities. Repairs are completed at our Vadodara facility (Gujarat). Turnaround is typically 3-5 weeks for major repairs with full functionality certification.
What is the typical cost and lead time for CTI turbomolecular pump repair?+
CTI pump repair costs depend on fault severity—magnetic bearing realignment runs INR 25,000–45,000; bearing module replacement, INR 50,000–80,000; rotor re-balancing, INR 15,000–30,000. Lead time is 2–4 weeks after intake, including parts sourcing and thermal vacuum testing. Synchronics provides upfront quotations and repair schedules upon inspection.
Can you repair older CTI pump models or provide refurbished units?+
Yes. Synchronics maintains a stock of refurbished CTI pump cartridges and control electronics. We repair models from the 1990s onwards—CTI 50, 125, 250, 500, 1200 series. Exchange units can be shipped within 5 working days. All refurbished units include 6-month warranty and thermal vacuum certification test reports.
Does Synchronics supply spare parts for CTI equipment?+
Yes. We stock bearing cartridges, magnetic bearing modules, solenoid coils, diaphragms, thermal sensors, power supply components, and helium compressor cold head cartridges. Most common CTI spares are in-stock; specialized items are sourced within 2 weeks. We also provide wiring diagrams, spare parts lists, and maintenance manuals for Indian customers.
How does Synchronics test CTI pumps after repair?+
All CTI turbomolecular pumps undergo functional testing on dedicated test rigs with thermal vacuum chambers. Magnetic bearing stability is verified over 2–4 hours at operating speed. Pressure curves, vibration signatures, and thermal profiles are logged and compared to OEM baseline data. Helium compressors are tested for discharge pressure, flow rate, and cold head equilibrium temperature. Full test reports are provided with certificate of repair.
How do I send my CTI 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 CTI 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 CTI 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 CTI 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.
