HANNING Product Lines We Repair
Our engineers are trained on the full HANNING product range. Below are the major product families we service.
EC Motor Controllers
Electronically commutated (brushless DC) motor control modules with integrated feedback loops. Common faults include sensor signal loss, PWM stage failure, thermal shutdown loops, and communication protocol errors on CAN or 0-10V analog inputs.
Centrifugal Fan Drive Modules
Integrated fan speed controllers with soft-start, overvoltage protection, and ambient temperature compensation. Typical failures: capacitor bank degradation, relay chatter, thermistor malfunction, and EMC filter breakdown under industrial noise environments.
Intelligent Sensor Integration Boards
Peripheral control modules integrating pressure, temperature, and speed sensors with CAN gateway functionality. Common issues: sensor interface chip failure, CAN transceiver shorts, ADC calibration drift, and firmware corruption affecting multi-unit synchronization.
Industrial HVAC Gateway Units
Network-enabled controllers bridging HANNING drives to building management systems via Modbus TCP or proprietary protocols. Repair challenges include ethernet port failure, real-time clock drift, SD card corruption, and authentication failure after firmware updates.
High-Efficiency EC Power Supplies
Dedicated 24VDC and 48VDC switched-mode supplies for multi-motor installations with redundancy and monitoring. Typical faults: primary stage MOSFET burnout, control IC failure under voltage transients, and output regulation loss due to optocoupler degradation.

Common HANNING Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HANNING equipment arriving at our workshop.
- ✓EC motor sensor signal dropout and stalling — Hall-effect sensor connector corrosion or internal sensor chip failure is common in Indian humid climates, especially in food and pharmaceutical cold storage where salt spray and moisture ingress degrade sensor leads. Synchronics performs sensor interface diagnostics and conducts full ohm-meter profiling to isolate sensor versus connector faults.
- ✓PWM output stage thermal runaway and shutdown — HANNING's high-frequency PWM stages generate heat under extended full-load operation common in Indian textile and chemical plants. Thermal paste degradation, heatsink contact loss, or internal junction failures prevent proper heat dissipation, triggering protective shutdown at 80-85°C rather than design-rated 100°C.
- ✓CAN bus communication timeout and protocol errors — HANNING's CAN transceivers (NXP or TI variants) suffer signal integrity loss in industrial plants near welding equipment or high-power motor starters. EMC filtering inadequacy and stub-length violations on rushed installation cause bit-error rates that lock out multi-fan synchronization systems.
- ✓Soft-start relay chatter and nuisance tripping — HANNING FanControl modules use sealed relays rated for 500,000 cycles; Indian industrial environments with frequent power surges and unstable supply degrade contact resistance faster. Inrush current limiting circuits fail, causing contact bounce and arc erosion that creates intermittent open-circuit conditions.
- ✓Thermistor calibration drift causing false overtemp shutdowns — HANNING drives use NTC thermistors mounted directly on heatsinks for ambient temperature compensation. Long-term thermal cycling in Indian climate swing (5°C winter to 50°C summer) causes R-T curve aging, misinterpreting normal operating temperature as critical overheat condition.
- ✓CAN node address conflict and duplicate ID assignment — In multi-unit installations typical of Indian food processing and beverage plants, HANNING GatewayHVAC units can assign conflicting node addresses during power-up if backup battery fails. Slave units broadcast identical CAN IDs, silencing gateway communication and cascading system shutdown.

Frequently Asked Questions — HANNING Repairs
Do you repair HANNING equipment anywhere in India?+
Yes. Synchronics Electronics repairs the complete HANNING product range — EC motor controllers, centrifugal fan drives, sensor integration modules, and intelligent gateway units. We offer PAN-India door pickup service from major cities including Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Kolkata, Ahmedabad, and Surat. All repairs are performed at our factory-certified facility in Vadodara, Gujarat with 48-72 hour TAT for most HANNING electronics.
What is HANNING's EC motor technology and why does it fail?+
HANNING EC (electronically commutated) motors are brushless DC motors controlled by sophisticated PWM electronics that adjust speed based on pressure, temperature, or network commands. They fail primarily due to Hall-effect sensor corrosion in humid Indian climates, PWM transistor thermal runaway under sustained full load, and CAN communication loss in electromagnetically noisy industrial plants. Synchronics specializes in EC motor diagnostics and rebuilds, restoring efficiency and eliminating nuisance shutdowns.
Can Synchronics repair HANNING drives that are integrated into third-party HVAC systems?+
Yes, absolutely. Many Indian food processing, pharmaceutical, and data center installations embed HANNING EC drives into custom or OEM HVAC skids. Synchronics repairs these standalone, performs electrical isolation testing to confirm no damage to building management system interfaces, and provides technical documentation of any modifications needed for safe re-integration. We coordinate with your system integrators if required.
Do you stock HANNING spare parts and repair components?+
Synchronics maintains an active inventory of common HANNING consumables including thermal interface materials, relay modules, capacitor banks, and sensor assemblies. For controller-specific components like PWM IGBTs or CAN transceivers, we source OEM-equivalent industrial-grade variants within 2-3 working days. All parts are tested before installation and come with repair warranty.
How quickly can Synchronics repair a failed HANNING fan controller in an Indian pharma plant?+
For critical downtime situations, Synchronics offers same-shift diagnostic (4-hour window) and next-day emergency repair turnaround on HANNING controllers. We pick up from your facility, bench-test immediately in Vadodara, and deliver repaired units or provide loaner controllers to maintain climate stability. Emergency callouts incur 25% premium but prevent product spoilage in temperature-sensitive manufacturing.
How do I send my HANNING 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 HANNING 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 HANNING 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 HANNING 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.
