HEINRICHS Equipment We Repair — By Category
HEINRICHS Product Lines We Repair
Our engineers are trained on the full HEINRICHS product range. Below are the major product families we service.
Heinrichs Thyristor Modules and Power Controllers
Solid-state power switching devices used in resistance heating circuits for furnaces, ovens, and process heaters. Common failures include thyristor gate control faults, output stage burnout, and firing circuit instability causing temperature oscillation or complete heating loss.
Heinrichs Temperature Controllers and PID Units
Digital and analog temperature regulation controllers with multiple input types and relay/analog outputs. Typical issues include sensor input failures, display malfunction, control loop oscillation, and calibration drift affecting setpoint accuracy and process repeatability.
Heinrichs Heating Element Assemblies
Immersion and surface heating elements with integrated protection and switching circuits. Common repair needs include element burnout, terminal corrosion, insulation breakdown, and thermal sensing probe failures in harsh chemical and steam environments.
Heinrichs Digital Display and Sensor Modules
Multi-function display units with RTD, thermocouple, and resistance input interfaces for real-time temperature monitoring. Frequent failures involve sensor connector corrosion, input circuit damage, LCD display failure, and analog-to-digital conversion errors in humid plant environments.
Heinrichs Relay and Contactor Interface Boards
Control interface modules managing heating element contactor switching and load distribution across multiple heating zones. Common faults include relay coil burnout, contact welding, signal isolation failures, and switching noise causing nuisance shutdowns in high-vibration industrial settings.
Heinrichs Process Automation Interfaces
Gateway modules providing Ethernet/Profibus connectivity between heating systems and plant SCADA networks. Typical issues include communication protocol errors, port failures, IP address conflicts, and data logging corruption affecting process traceability.

Common HEINRICHS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HEINRICHS equipment arriving at our workshop.
- ✓Heinrichs thyristor gate drive circuit failure — Optocoupler degradation or gate resistor burnout in the control stage causes loss of thyristor switching signal. This typically occurs after 8-12 years in high-temperature furnace environments or after voltage surge damage from power network instability common in Indian industrial areas.
- ✓Heinrichs temperature sensor input circuit burnout — RTD or thermocouple lead-in protection circuits fail when moisture ingress or corrosive gas penetration causes insulation breakdown. Chemical and pharmaceutical plants in Gujarat and Maharashtra report this fault when sensor connectors lack adequate IP-rated sealing.
- ✓Heinrichs control loop oscillation and hunting — PID tuning parameters drift or proportional band setting becomes mismatched after firmware update or after relay switching delay increases due to contact wear. Temperature swings of 20-30°C occur in critical batch processes, especially in autoclave and sterilizer applications.
- ✓Heinrichs digital display LCD segment failure — LCD segment crystallization or backlight LED failure causes partial or complete loss of temperature readout visibility. Common in automotive paint-cure ovens and injection molding machines operating continuously at elevated ambient temperatures above 45°C.
- ✓Heinrichs relay contact welding and switching failure — Inductive switching transients or excessive load current cause main heating element contactor contacts to weld closed, preventing heating cutoff. Arc suppression circuits degrade over time in high-vibration textile and chemical plants, leading to uncontrolled heat rise and thermal runaway.
- ✓Heinrichs Profibus communication timeouts and data errors — Shielded cable degradation, connector pin corrosion, or galvanic isolation circuit failure disrupts serial communication with plant SCADA. Poor grounding practices in Indian industrial facilities exacerbate EMI coupling into signal lines running alongside high-current power cables.

Frequently Asked Questions — HEINRICHS Repairs
Do you repair Heinrichs equipment anywhere in India?+
Yes. Synchronics repairs the full Heinrichs product range — thyristor controllers, temperature regulators, heating element assemblies, and process automation modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Indore, Jaipur, and all other major cities. All repairs completed at our Vadodara facility with 48-72 hour turnaround for non-component replacements.
What is the typical repair time for Heinrichs thyristor power modules?+
Standard diagnosis and component-level repair (optocoupler replacement, gate drive restoration) takes 24-36 hours at Synchronics. If thyristor power stage replacement is needed, we maintain stock of Heinrichs original and approved equivalent thyristors for common modules (HV3000, HV5000). High-voltage testing and firing angle calibration add 6-8 hours before return shipment.
Can Synchronics repair Heinrichs controllers damaged by power surges or lightning strikes?+
Yes. Synchronics specializes in surge-damaged industrial electronics repair. We assess damage to input protection circuits, gate drive stages, and output relay drivers. Most surge damage is repairable through component-level replacement and transient suppression circuit enhancement. We recommend adding external varistor or MOV protection on customer site to prevent recurrence in lightning-prone regions.
Do you have spare parts stock for Heinrichs heating elements and sensor probes?+
Synchronics maintains stock of common Heinrichs heating element variants (immersion 2-3kW and surface heating 1-2kW) and RTD/thermocouple probe assemblies. For specialty high-watt-density elements or custom sensor configurations, we source original parts directly from Heinrichs distributors in Germany with 5-7 day delivery to India. Emergency same-day substitution possible for standard industrial RTD and sheath thermocouples.
How does Synchronics handle Heinrichs equipment under warranty or OEM support contracts?+
Synchronics is an independent authorized repair partner for Heinrichs in India. We provide warranty-compliant repairs documented with full troubleshooting reports and component-level repair certifications. Many Indian plants use Synchronics repairs to extend equipment life beyond OEM warranty period cost-effectively. We coordinate with your Heinrichs OEM support team if OEM warranty is still active.
How do I send my HEINRICHS 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 HEINRICHS 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 HEINRICHS 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 HEINRICHS 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.
