HEIDOLPH Product Lines We Repair
Our engineers are trained on the full HEIDOLPH product range. Below are the major product families we service.
Rotary Evaporator Systems
Heidolph rotovaps are precision evaporation units used for solvent removal in pharmaceutical and chemical synthesis. Common issues include motor speed fluctuations, vacuum loss, condenser ice-bath temperature instability, and electronic control board failures.
Overhead Stirrer Systems
Heavy-duty industrial and laboratory overhead stirrers engineered for viscous media mixing. Failures typically involve brushed motor wear, gear slippage, electronic speed controller faults, and bearing degradation under continuous operation.
Immersion Circulators and Heating Baths
Precision temperature control devices for constant-temperature reactions and sample equilibration. Repair needs include temperature sensor (RTD/thermistor) failures, heating element open circuits, electronic PID controller drift, and coolant pump cavitation.
Vacuum Pump and Control Electronics
Integrated vacuum regulation systems and electronic pressure controllers for rotovap and distillation applications. Common faults: vacuum transducer signal drift, solenoid valve sticking, diaphragm pump motor failure, and control board capacitor failure.
Condenser and Cooling Modules
Liebig and Graham condensers paired with integrated coolant circulation. Failures stem from ice-bath temperature sensor malfunction, peristaltic pump wear, internal tube blockage, and thermal control instability.
Electronic Control and Monitoring Boards
Custom PCBs managing motor speed, temperature, vacuum levels, and safety interlocks. Typical repairs: electrolytic capacitor leakage, relay contact corrosion, microcontroller firmware recovery, sensor input conditioning circuit failure.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common HEIDOLPH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HEIDOLPH equipment arriving at our workshop.
- ✓Rotovap motor speed fluctuation or stalling — Worn carbon brushes in the universal motor, degraded motor controller capacitors, or slip-ring contact oxidation. Continuous operation over 2000+ hours without maintenance accelerates wear.
- ✓Temperature controller not reaching setpoint or oscillating — RTD temperature sensor (Pt100) open circuit or calibration drift, PID tuning parameters corrupted, or heating element partial failure. Common in immersion circulators running continuous synthesis runs.
- ✓Vacuum loss or weak vacuum reading — Solenoid vacuum valve stuck in diaphragm pump module, vacuum transducer sensor signal dropout, or internal condenser/rotovap seals degraded. Heidolph vacuum lines are prone to micro-leak accumulation.
- ✓Overhead stirrer motor grinding or loss of torque — Worm gear lubricant breakdown or contamination, motor bearing race spalling, or brush-commutator arcing in brushed DC motors. Heavy viscosity media (polymers, slurries) accelerate gear wear.
- ✓Immersion circulator pump not circulating coolant or making noise — Peristaltic pump tubing perished or kinked, inlet check valve clogged by mineral deposits, cavitation from low coolant level, or pump motor winding short. Soft water use in Indian facilities causes calcium deposit buildup.
- ✓Electronic control board not responding to keypad or display blank — Backup battery failure (CMOS RAM loss), microcontroller EEPROM corruption, cracked PCB solder joints near power entry, or capacitive touch panel sensor malfunction. Power supply surges during Indian grid fluctuations cause this.

Frequently Asked Questions — HEIDOLPH Repairs
Do you repair Heidolph equipment anywhere in India?+
Yes. Synchronics is an authorized Heidolph repair partner across India. We offer PAN-India door pickup and delivery for rotovaps, stirrers, immersion circulators, and control electronics from all Heidolph product lines. Facility in Vadodara, Gujarat. Turnaround: 5-10 working days for most units. Express services available for critical downtime situations.
My Heidolph rotovap shows 'Vacuum Fail' error. What should I do?+
Heidolph rotovap vacuum failures typically signal transducer malfunction, solenoid valve sticking, or pump diaphragm rupture. Before sending in: check hose connections are tight, verify water to the condenser is circulating, and confirm the vacuum pump motor is running. Synchronics will diagnose the fault with vacuum manometry and replace the specific failed component — often a $200-400 repair versus $3000+ for unit replacement.
Can Synchronics service Heidollah equipment with OEM parts or only compatible replacements?+
Synchronics stocks genuine Heidolph OEM parts for all major repairs — motors, pumps, solenoids, control boards, and sensors. We maintain a parts inventory covering rotovaps, stirrers, and immersion circulators. Where OEM parts are unavailable, we qualify equivalent components with full functional verification. All repairs carry a 12-month warranty.
What is your experience with Heidolph overhead stirrer motor and gearbox repair?+
Synchronics has repaired 100+ Heidolph RZR series stirrers for pharmaceutical and chemical plants across Gujarat, Maharashtra, and Rajasthan. Common repairs: brushed motor recondition (Rs 2500-4500), worm gearbox overhaul with lubricant replacement (Rs 3500-6000), and speed controller recalibration. We perform full torque load testing and provide mixing curve verification before shipment.
How much does Heidolph rotovap repair typically cost?+
Routine Heidolph rotovap repairs (motor brushes, temperature sensor, solenoid valve) cost Rs 4,000-8,000. Complex repairs (condenser seal replacement, full electronics rebuild) run Rs 8,000-15,000. Estimates are provided after fault diagnosis. Many repairs cost 60-70% less than new unit purchase, making Synchronics repair a smart choice for Indian manufacturers managing capital equipment budgets.
How do I send my HEIDOLPH 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 HEIDOLPH 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 HEIDOLPH 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 HEIDOLPH 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.
