H+H Equipment We Repair — By Category
H+H Product Lines We Repair
Our engineers are trained on the full H+H product range. Below are the major product families we service.
H+H Heating Controllers
Precision electric heating control modules used in textile dyeing, chemical processing, and plastic extrusion. Common faults include sensor drift, contactor relay failure, and firmware calibration errors affecting temperature accuracy and ramp-up speed.
H+H Temperature Regulation Units (TRU)
Integrated thermostatic and flow-control systems for closed-loop thermal management in molding and casting. Typical issues include proportional valve stiction, sensor nonlinearity, and PID tuning drift leading to temperature overshoot or undershoot.
H+H Digital Display Modules
Touchscreen and LED diagnostic interfaces for real-time temperature and process monitoring. Repair-critical failures include LCD panel degradation, RS485 communication hangs, and configuration memory corruption.
H+H Sensor Interface Cards
Analog input conditioning and signal conversion modules for RTD, thermocouple, and resistance bridge inputs. Common defects: input amplifier offset drift, ADC quantization noise, and isolation barrier breakdown under vibration.
H+H Power Supply Modules
Industrial-grade 24V DC and 48V DC regulated power modules for heating control systems. Typical failures: capacitor dry-out, thermal shutdown trigger under continuous load, and output voltage regulation drift after thermal cycling.

Common H+H Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in H+H equipment arriving at our workshop.
- ✓Temperature sensor drift and calibration loss — H+H RTD and thermocouple input modules suffer sensor signal degradation due to PCB moisture ingress in humid Indian environments, corrosion of connector pins, and long-term amplifier offset drift. Symptoms include slow temperature response and ±5-10°C reading errors.
- ✓Heating contactor relay chattering and coil failure — H+H heating control modules rely on mechanical relays to switch high-current heating elements. Repeated thermal cycling, dust ingress in poorly sealed enclosures, and inadequate snubber capacitors cause contact bounce, arcing, and eventual coil open-circuit or shorted turns.
- ✓Proportional valve stiction in temperature regulation units — H+H TRU series proportional valves stick due to sludge buildup from degraded heat transfer fluid, corrosion of spool guides, and loss of pilot pressure. This prevents smooth temperature control and causes overshoot or cold-start delays.
- ✓LCD display module pixel failure and screen degradation — H+H digital display modules (DDM series) suffer LCD panel deterioration due to sustained 40-50°C operating temperatures near heat sources, backlight inverter aging, and long-term contrast loss. Pixels become stuck or fade, making process readouts unreadable.
- ✓RS485 communication timeout and Modbus hang — H+H heating controllers with networked temperature displays lose RS485 link due to termination resistor failure, ground loop noise in long cable runs (common in Indian textile mills with inadequate plant wiring), and receiver IC latch-up under EMI transients.
- ✓Thermal shutdown and power supply overtemperature shutdown — H+H PSM power supply modules trigger thermal shutdown at lower-than-expected load due to aged bulk capacitors, cooling fan bearing wear, and dust caking on heatsinks. This causes intermittent heating shutdowns during peak production shifts.

Frequently Asked Questions — H+H Repairs
Do you repair H+H equipment anywhere in India?+
Yes. Synchronics repairs the full H+H product range — heating controllers, temperature regulation units, display modules, sensor interface cards, and power supplies. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other metros and Tier-2 cities. All repairs are performed in our Vadodara, Gujarat facility with turnaround time of 5-10 working days including testing and calibration.
What is the typical turnaround time for H+H heating controller repair?+
H+H heating controller repairs typically take 5-7 working days including fault diagnosis, component replacement, calibration, and thermal validation. If sensor recalibration or proportional valve cleaning is required, add 2-3 days. We offer 24-48 hour express service for critical production faults; customers pay additional express shipping and priority bench fees. Emergency same-day bench diagnosis is available upon request.
How do you handle H+H sensor calibration and certification?+
Synchronics recalibrates H+H RTD and thermocouple input modules using NIST-traceable reference standards and decade resistance boxes. We validate input linearity across the specified temperature range (typically 0-100°C or custom span), document offset and gain errors, and provide signed calibration certificates with measurement uncertainty bands. All calibrations comply with ISO 9001 standards and Indian pharmaceutical/food industry requirements.
Can you repair H+H display modules that show garbled or missing temperature readouts?+
Yes. Garbled displays usually indicate LCD panel pixel failure, corrupted display firmware, or RS485 communication errors. Synchronics performs non-destructive firmware re-flash, replaces defective LCD panels with industrial-grade equivalents, and tests RS485 handshake under real Modbus load. We also check power supply ripple and backlight inverter function. Most display faults are resolved within 3-4 days.
Do you stock original H+H replacement parts or use compatible third-party components?+
Synchronics maintains stock of critical H+H components: relay coils, electrolytic capacitors (high-temperature rated), RS485 transceiver ICs, sensor interface amplifiers, and LCD display panels. For OEM-branded components, we source genuine H+H parts through authorized Indian distributors with lead times of 7-14 days. For non-critical items, we use industrial-grade equivalents (same ratings and pinout) to minimize cost while maintaining performance. All parts are tested in final validation before shipment.
How do I send my H+H 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 H+H 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 H+H 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 H+H 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.
