KUHNKE Equipment We Repair — By Category
KUHNKE Product Lines We Repair
Our engineers are trained on the full KUHNKE product range. Below are the major product families we service.
KUHNKE Electromagnetic Relays
General-purpose and industrial relays with coil voltages ranging from DC 5V to AC 400V. Common faults include coil burnout, contact erosion, armature stiction, and chatter. Used extensively in Indian textile mills, printing presses, and machinery control cabinets.
KUHNKE Solenoid Valves and Actuators
2/2, 3/2, and 4/3 solenoid-operated directional control valves for pneumatic and hydraulic systems. Repair focuses on coil insulation breakdown, spool stiction, and seal degradation causing leakage in Indian food processing and automotive assembly plants.
KUHNKE Control Modules and Switching Units
Modular switching and logic control units for machinery automation. Faults typically involve PCB corrosion, relay contact failure, and power supply regulation issues in humid industrial environments across India.
KUHNKE Contactor and Motor Control Devices
Industrial-grade contactors and soft-starters for motor control in Indian pump stations, compressor systems, and textile machinery. Common issues include coil burning, contact pitting, and thermal overload trips.
KUHNKE Timing Relays and Time-Delay Modules
On-delay, off-delay, and pulse-timer modules used in Indian process automation and safety circuits. Faults include capacitor drift, RC circuit aging, and relay chatter at module level.
Why Choose Synchronics for KUHNKE Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on KUHNKE equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
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 KUHNKE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KUHNKE equipment arriving at our workshop.
- ✓KUHNKE relay coil burnout and insulation failure — Prolonged voltage overspike, incorrect coil voltage applied, or moisture ingress causing partial short in the coil windings. Common in Indian factories with poor power conditioning or high humidity near coastal plants.
- ✓Contact welding and pitting in KUHNKE relays — High inrush current, arc discharge during switching, or contaminated contact surfaces. Particularly seen in Indian heavy machinery and textile mills operating 24/7 under harsh dust conditions.
- ✓Solenoid valve spool stiction and sluggish response — Varnish buildup in hydraulic lines, sand contamination in pneumatic systems, or corrosion on the spool valve lands. Frequent in Indian water treatment plants and food processing lines with contaminated media.
- ✓KUHNKE armature chatter and erratic switching — Loose armature mechanically, air gap misalignment, or AC coil hum combined with weak spring tension. Common when relay mounting is loose or vibration from nearby machinery affects the control cabinet.
- ✓Solenoid coil insulation breakdown and winding short — Moisture from condensation in humid Indian climates, repeated thermal cycling in un-airconditioned cabinets, or manufacturing defect in the coil wrap. Typically results in partial winding short and loss of magnetic force.
- ✓Control relay module PCB corrosion and track failure — Salt spray in coastal Indian factories, humidity in non-climate-controlled warehouses, or condensation in poorly sealed electrical enclosures. Corrosion on PCB traces or component leads causes intermittent circuit faults.

Frequently Asked Questions — KUHNKE Repairs
Do you repair KUHNKE equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full KUHNKE product range including electromagnetic relays, solenoid valves, control modules, and contactors. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bengaluru, Kolkata, and all tier-2 cities. All repairs are completed in our Vadodara, Gujarat facility by trained technicians certified in relay and solenoid repair.
What is your typical turnaround time for KUHNKE solenoid valve repair?+
Standard KUHNKE solenoid valve repairs take 5-7 working days including diagnostics, disassembly, cleaning, seal replacement, and functional testing under load. Urgent repairs can be expedited to 48 hours if required. For coil rewinds, turnaround extends to 10-12 days. We test all repaired valves on test benches simulating your application parameters before dispatch.
Can Synchronics handle KUHNKE relay coil rewind and custom voltage conversions?+
Yes. Synchronics operates a full coil rewinding facility for KUHNKE electromagnetic relays and solenoid coils. We can rewind coils to original specifications or custom voltages (DC 5V through AC 400V). Our rewound coils match OEM insulation class and winding density. We also test coil performance on our automated test rigs before final assembly into relay modules.
Do you stock KUHNKE spare parts and replacement modules?+
Synchronics maintains stock of commonly replaced KUHNKE components including contact bridges, armature assemblies, solenoid coils, seals, and springs. For OEM-original parts, we source directly from KUHNKE's German headquarters or authorized distributors with 1-2 week lead times. Emergency parts can often be sourced from our relationship with Indian electrical wholesalers within 24-48 hours.
What documentation do you provide after KUHNKE equipment repair?+
Every KUHNKE repair includes a detailed test report with before/after megohm readings, coil resistance, contact gap, valve flow rates, and switching times. We provide a 12-month warranty on all repairs covering parts and labor. For critical equipment, we offer preventive maintenance contracts with quarterly inspections, lubrication of solenoid spools, and coil insulation monitoring to extend KUHNKE device life.
How do I send my KUHNKE 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 KUHNKE 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 KUHNKE 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 KUHNKE 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.
