HSI Product Lines We Repair
Our engineers are trained on the full HSI product range. Below are the major product families we service.
Immersion Heaters (Electric Screw-In & Flange-Mounted)
Direct immersion heating elements for tanks, vessels, and process streams. Common failures include element burnout, terminal block corrosion, and thermowell damage from thermal shock or sediment accumulation in high-mineral water applications.
Circulation Heaters (Inline Process Heat Exchangers)
Closed-loop heating for liquid circulation systems in plastics extruders, chemical reactors, and food processing. Typical faults: element failure under pressure, scale buildup reducing heat transfer, and pressure vessel corrosion in aggressive media.
Temperature Controllers & Thermal Management Units
PID-based control modules with analog and digital inputs for precise temperature maintenance. Failures include sensor signal loss, relay chattering, calibration drift, and firmware glitches under power surges common in Indian industrial environments.
Thermal Sensors & Thermowells
RTD and thermocouple assemblies with stainless steel protection tubes for harsh environments. Common issues: sensor lag from fouling, well corrosion in acidic or saline processes, and connector oxidation in humid coastal Indian plants.
Energy-Efficient Modular Heating Systems
Stackable, multi-element heating units for large-scale industrial applications. Challenges: uneven element aging, phase balancing issues in 3-phase systems, and thermal expansion stress in aluminum or composite housings.

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 HSI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HSI equipment arriving at our workshop.
- ✓Element open circuit or burnout failure — Nichrome wire degradation under sustained high temperature, moisture ingress causing internal corrosion, or excessive current from scaling/mineral deposits reducing resistance and overheating the element coil.
- ✓Thermowell or sensor fouling and signal loss — Mineral scale, process chemical deposits, or biological growth coating the thermowell exterior, creating thermal lag or complete loss of RTD/thermocouple signal to the controller.
- ✓Temperature overshoot or undershoot in control loop — PID tuning drift due to aging sensor, calibration error, loose terminal connections causing intermittent signal, or relay switching hysteresis in older HSI controller modules.
- ✓Pressure vessel or flange corrosion and weeping leaks — Galvanic corrosion in mixed-metal flanges, aggressive process chemicals (acids, salts) attacking stainless steel, or stress corrosion cracking from thermal cycling in Indian monsoon conditions affecting coastal plants.
- ✓Multi-element imbalance and uneven heating — Age-related element resistance drift in parallel-connected stacks, capacitor bank failure in 3-phase balancing circuits, or loose inter-element busbars causing current redistribution and premature burnout of weaker elements.
- ✓Connector oxidation and intermittent contact loss — Exposed copper terminals in humid tropical Indian environments, loose wire stranding creating high resistance, or IP-rated connectors with failed seals allowing ingress of moisture and salt spray near coastal facilities.

Frequently Asked Questions — HSI Repairs
Do you repair HSI equipment anywhere in India?+
Yes. Synchronics repairs the full HSI product range — immersion heaters, circulation heaters, temperature controllers, thermal sensors, and modular heating systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, Bangalore, and all other cities. Single repair facility in Vadodara, Gujarat with 180+ engineers and OEM test benches for every HSI product family.
How do I know if my HSI immersion heater element has failed?+
Common signs: no temperature rise after 30 minutes, intermittent heating, burning smell from the element, or loss of electrical continuity measured across the terminals with a multimeter. Synchronics performs non-destructive megohm insulation testing (>50 MΩ for healthy elements). If resistance is <1 MΩ or infinite (open circuit), element replacement is required. We test your replacement element under your exact voltage, phase, and fluid conditions before shipping back.
What is the typical repair turnaround time for HSI circulation heaters?+
Synchronics delivers HSI circulation heater repairs in 7-10 working days for element replacement, seal kit overhauls, and pressure testing. For thermal controller reprogramming or sensor recalibration, turnaround is 3-5 days. Complex cases (corrosion mitigation, material upgrades, custom flange modifications) may take 12-15 days. Express 48-hour emergency service available for critical production lines — contact our Vadodara facility directly for same-day diagnostic assessment.
Can you refurbish older HSI thermal management modules with modern PID controllers?+
Yes. Synchronics retrofits legacy HSI analog controllers with digital PID modules maintaining the original flange, wiring harness, and sensor connections. We program new controllers to match your existing process setpoints and tuning parameters. Retrofit cost is typically 40-50% of a new HSI unit. All upgrades include calibration verification and 12-month warranty on controller function.
Do you supply replacement parts for HSI equipment or only repair complete units?+
Synchronics repairs complete HSI assemblies with warranty. We source genuine HSI spare parts (elements, seals, thermowells, connectors, capacitor banks) directly from German suppliers and maintain a parts inventory for rapid turnaround. For non-critical consumables (gaskets, fasteners, wire), we use OEM-compatible industrial equivalents certified to match HSI specifications. Request a parts quote if you prefer to supply your own materials.
How do I send my HSI 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 HSI 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 HSI 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 HSI 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.
