BRUNNER Product Lines We Repair
Our engineers are trained on the full BRUNNER product range. Below are the major product families we service.
Brunner Temperature Control Units (TCU)
Compact and industrial-scale temperature control units for injection molding, die-casting, and extrusion processes. Common issues include sensor drift, heater element burnout, and PID controller malfunction affecting process temperature stability.
Brunner Circulation and Heating Systems
Modular circulation pump systems with integrated heating for water and oil-based cooling loops. Faults typically involve pump cavitation, heater short-circuits, and flow sensor failures impacting thermal cycling speed.
Brunner Thermostat and Sensor Controllers
Precision thermostatic controllers with analog and digital interfaces for setpoint regulation and alarm logic. Common defects include RTD/thermocouple sensor breakage, relay contact corrosion, and display panel failures.
Brunner Heating Element Assemblies
Immersion and flanged electric heating elements rated up to 400V three-phase. Failures manifest as partial heating, element burnout, and terminal corrosion affecting power delivery and temperature ramp rate.
Brunner Process Fluid Management
Complete fluid handling systems for chilled water, hot water, and thermal oil distribution in multi-zone manufacturing environments. Failures include valve stiction, fluid oxidation, and blockage in heat exchanger circuits.

Common BRUNNER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BRUNNER equipment arriving at our workshop.
- ✓Brunner thermostat sensor open-circuit fault — RTD (resistance temperature detector) or thermocouple connectors oxidize due to moisture ingress or vibration loosening in high-humidity manufacturing environments. Brunner sensor leads are exposed at terminal blocks, making corrosion a common field failure in Indian textile, chemical, and plastics plants.
- ✓Brunner circulation pump cavitation and noise — Pump inlet suction lines develop air leaks or fluid level drops below minimum in the Brunner reservoir tank, causing vapor pocket formation in the pump chamber. Common in Indian pharmaceutical and food processing facilities with inconsistent fluid maintenance schedules.
- ✓Brunner heater element burnout and tripped breaker — Electric heating elements in Brunner TCU units short internally due to moisture ingress through element gaskets or terminal degradation from thermal cycling stress. Three-phase phase imbalance or undersized breaker settings accelerate element failure in Indian industrial power environments.
- ✓Brunner PID controller sluggish response or temperature overshoot — Tuning parameters (Kp, Ki, Kd gains) drift out of calibration, sensor response lag increases due to fouling, or setpoint adjustment potentiometer contacts develop intermittent resistance. Brunner controllers are sensitive to slow sensor feedback in fast-cycling processes.
- ✓Brunner temperature display shows erratic readings or blanks intermittently — LCD panel connector corrosion, loose ribbon cable between main PCB and display module, or internal voltage regulator failure on the Brunner controller board. Power supply ripple from nearby VFD or welding equipment can trigger display dropout.
- ✓Brunner valve block internal leakage and setpoint drift — Solenoid valve spool stiction or erosion in Brunner multi-way valve blocks causes internal cross-leakage between supply and return lines, resulting in uncontrolled temperature drift. Contaminated Brunner fluid (water or metal particles) accelerates valve seat wear in Indian industrial environments with poor fluid maintenance.

Frequently Asked Questions — BRUNNER Repairs
Do you repair Brunner equipment anywhere in India?+
Yes. Synchronics repairs the full Brunner temperature control, heating system, and thermal management product range across India. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities. All repairs are performed at our central facility in Vadodara, Gujarat with 24-48 hour turnaround for most Brunner faults.
What makes Brunner temperature control units fail in Indian manufacturing plants?+
Brunner TCU failures in India are typically caused by: (1) sensor corrosion from high humidity in coastal and monsoon regions, (2) heater element burnout due to phase imbalance in Indian three-phase power supplies, (3) circulation pump cavitation from inconsistent fluid maintenance, and (4) controller tuning drift in fast-cycling plastic and die-cast processes. Synchronics has repaired 500+ Brunner units across Indian facilities and understands these regional failure patterns.
How do you source Brunner spare parts and components?+
Synchronics maintains direct sourcing relationships for genuine Brunner components including heater elements, circulation pump impellers, solenoid valves, thermostats, and controller modules. We also stock compatible replacement parts for legacy Brunner models no longer in production. All parts are tested before installation and come with repair warranty.
Can you repair Brunner equipment remotely or provide field service?+
Synchronics offers remote diagnostics via video call or email for basic Brunner troubleshooting and can advise on temporary fixes. For hands-on repairs, we arrange door pickup across India — customers ship equipment via courier to Vadodara or our technicians visit large facilities for on-site work. Field service rates apply for direct customer site visits.
What warranty do you provide on Brunner repairs?+
Synchronics guarantees 12 months on all repaired Brunner equipment including controller cards, heater elements, circulation units, and sensor replacements. Warranty covers defects in workmanship and component failure (not wear or misuse). Extended warranty and preventive maintenance contracts are available for continuous operation environments.
How do I send my BRUNNER 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 BRUNNER 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 BRUNNER 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 BRUNNER 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.
