HERZOG Product Lines We Repair
Our engineers are trained on the full HERZOG product range. Below are the major product families we service.
Herzog Temperature Controllers
Precision PID temperature controllers with dual display and alarm functions. Common issues include calibration drift, sensor input failures, relay contact degradation, and firmware corruption from power surges affecting setpoint stability.
Herzog Solid-State Relays (SSR)
Zero-crossing and random-fire SSRs for heating load control and three-phase AC switching. Typical failures include triac burn-out, snubber circuit failure, and thermal run-away due to inadequate heatsink contact or blocked cooling air.
Herzog Heating Element Assemblies
Immersion and circulation heaters with integrated thermostats and overheat protection. Repair work includes element rewinding, terminal replacement, thermostat recalibration, and insulation testing after moisture ingress or thermal cycling.
Herzog Process Control Modules
Modular PLCs with analog I/O, communication interfaces, and heating logic programming. Faults include corrupted ladder logic, analogue card faults, Modbus/RS485 interface failure, and power supply brownout damage.
Herzog Thermal Imaging & Monitoring Sensors
PT100 RTD, thermocouple transmitters, and non-contact IR sensors for process feedback. Failures stem from sensor drift, cable shielding degradation, connector corrosion, and transmitter input stage failure in wet or chemical environments.
Herzog Heating Transformer & Power Distribution
Step-down and isolation transformers with integral thermal cutouts and overload protection. Repair involves winding resistance testing, insulation breakdown diagnosis, core lamination inspection, and reassembly with proper termination.

Common HERZOG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HERZOG equipment arriving at our workshop.
- ✓Temperature overshoot and cycling instability — PID tuning parameters are corrupted or sensor calibration drifts due to thermal cycling in plastic injection or dyeing machines. Herzog controller setpoint becomes unreliable after power disturbance or firmware reset.
- ✓Solid-state relay fails to switch heating load — Triac element degrades from over-current spikes, snubber RC circuit fails due to surge exposure, or internal gate driver becomes intermittent. Herzog SSRs are exposed to unfiltered mains or poor load matching in Indian power conditions.
- ✓Modbus communication timeout and data loss — RS485 interface isolation transformer fails, cable shielding is compromised by moisture or EMI from adjacent motors, or Herzog PCM firmware locks up during rapid polling. Common in Indian plants with poor cable routing and frequent power sags.
- ✓Heating element resistance increases and power output drops — Nichrome wire oxidation accelerates in steam or humidity-rich environments; insulation breakdown between windings reduces heating capacity. Herzog heating cartridges and immersion heaters degrade faster in pharmaceutical and textile wet environments.
- ✓PT100 sensor reading error and temperature mismatch — Sensor lead resistance increases due to oxidized connectors or broken shielding; transmitter input stage fails from EMI coupling; sensor well is fouled by process deposits. Herzog sensor calibration drifts 3-5 degrees in high-vibration or corrosive duty.
- ✓Power supply brownout causes Herzog controller restart and setpoint loss — Inadequate mains filtering and surge protection allow voltage sags below 15% to reset microprocessor and erase user setpoints. Indian industrial power with frequent switching transients stresses Herzog supply capacitors and rectifier diodes.

Frequently Asked Questions — HERZOG Repairs
Do you repair Herzog equipment anywhere in India?+
Yes. Synchronics repairs the full Herzog product range — temperature controllers, solid-state relays, heating elements, process modules, and thermal sensors. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Surat, and all other cities. Same facility in Vadodara, Gujarat. Typical turnaround is 5-7 days for standard repairs, 10-14 days for rewinding and module rebuilds.
What is the typical cost to repair a Herzog EPC temperature controller versus replacement?+
Herzog EPC controller repair at Synchronics averages 40-50% of new purchase cost. We handle sensor recalibration, keypad replacement, display restoration, and firmware updates. If the microprocessor is damaged, replacement cost increases. We provide pre-repair quotation with turnaround time. Most Indian textile and pharmaceutical facilities recover repair investment within 2-3 months of restored production uptime.
Can Synchronics reprogram Herzog PLC modules and restore lost ladder logic?+
Yes, if you have a backup of the original program file or Herzog source code. Synchronics connects to Herzog PCM modules via serial/Ethernet, reads existing logic if accessible, and reprograms new logic via HerzogStudio software. If the code is lost and no backup exists, we help reconstruct the heating control logic based on your process documentation and I/O requirements. Firmware updates and security bit changes are also handled.
Why does my Herzog SSR keep failing after 6-12 months in our injection moulding plant?+
Herzog SSRs fail prematurely due to mains voltage surges, inadequate load matching, or poor heatsinking in dusty environments. Indian power instability and unfiltered switching loads (nearby servo drives, contactors) generate spikes that stress the triac. Synchronics rebuilds your SSR with enhanced snubber protection, recommends proper AC line filtering, and suggests upgrading heatsink contact surfaces. We also test the rebuilt unit on your actual mains and load conditions.
Do you stock Herzog spare components and offers warranty on repaired units?+
Synchronics maintains stock of common Herzog components including PT100 sensors, heating cartridges, relay contacts, electrolytic capacitors, and SSR triac modules. All repaired Herzog equipment carries a 12-month warranty covering parts and labour. Return freight to customer is included. Extended 24-month coverage is available for critical heating systems in pharmaceutical and automotive manufacturing.
How do I send my HERZOG 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 HERZOG 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 HERZOG 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 HERZOG 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.
