DAK Product Lines We Repair
Our engineers are trained on the full DAK product range. Below are the major product families we service.
Cartridge Heaters
High-density electrical resistance heating elements used in injection molding, extrusion, and industrial ovens. Common failures include element burnout, sheath corrosion, and loss of thermal contact in bore holes.
Immersion Heaters
Submerged heating elements for tanks, vessels, and process baths in pharmaceutical formulation and chemical synthesis. Failure modes include scale buildup reducing efficiency, thermowell breaches, and electrical insulation breakdown in corrosive media.
Temperature Sensors & RTDs
Precision platinum resistance thermometers (Pt100, Pt1000) and thermocouples (Type K, J, S) for process monitoring and feedback control. Drift in resistance values, broken sensor leads, and thermowell contamination are typical issues.
Heating Control Panels & Controllers
Integrated temperature regulation units with power thyristors, PID logic, and digital displays for batch and continuous heating processes. Common faults include thyristor gate drive failures, relay chattering, and display module burnout.
Heating Mantles & Jacketed Vessels
Fabric or ceramic heating sleeves for laboratory reactors, distillation apparatus, and small pilot-scale process equipment. Wear patterns in heating coils and insulation degradation over thermal cycles are common failure points.
Industrial Oven & Kiln Heaters
High-wattage resistance heating systems for batch ovens, annealing furnaces, and curing kilns in ceramics, metals, and composites manufacturing. Element sagging, refractory spalling, and uneven heat distribution are typical wear issues.

Common DAK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DAK equipment arriving at our workshop.
- ✓Cartridge heater complete burnout and loss of continuity — Sustained overload current, dry bore running without thermal contact, or end-of-life resistance drift causing thermal runaway. DAK elements typically fail after 2000-5000 operating hours under normal load.
- ✓RTD sensor reading drift and temperature measurement error — Platinum wire contamination, oxidation inside thermowell, cold junction reference drift in transmitter electronics, or lead wire resistance change due to corrosion. Common in humid pharma environments and corrosive chemical tanks.
- ✓Thyristor heating controller sudden power loss or uneven heat output — Gate drive optocoupler failure, power thyristor junction degradation, or snubber capacitor breakdown causing intermittent firing. Thermal cycling stresses solder joints in DAK power modules.
- ✓Immersion heater sheath corrosion and electrolyte ingress causing short circuit — Hairline cracks in stainless steel or copper sheath from stress corrosion cracking, chemical splash, or galvanic attack in acidic process tanks. Water ingress into insulation causes phase-to-earth faults within hours.
- ✓Digital temperature display showing erratic or frozen readings — Display module LCD failure, microcontroller program memory corruption from power surges, or sensor input signal conditioning circuit failure in DAK controller boards. Often triggered by facility electrical transients.
- ✓Heating mantle fabric deterioration and reduced heating power — Repeated thermal cycling causes ceramic fiber shrinkage and heating coil separation, reducing thermal contact. Moisture absorption in older fabric mantles reduces electrical insulation resistance below safe limits.

Frequently Asked Questions — DAK Repairs
Do you repair DAK heating equipment anywhere in India?+
Yes. Synchronics repairs the complete DAK heating element, sensor, and controller product range across all Indian states. We offer PAN India scheduled pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Surat, Jaipur, and all other industrial cities. All repairs are performed in our Vadodara, Gujarat facility with direct quality control oversight.
How long does DAK cartridge heater or immersion heater repair typically take?+
Element replacement and testing usually takes 5-7 working days from arrival. If thermowell re-machining or sensor recalibration is required, turnaround extends to 10-12 days. We provide daily status updates and expedite high-priority pharmaceutical production repairs within 48 hours on request.
Can you repair DAK temperature controllers and provide calibration certificates?+
Absolutely. Synchronics rebuilds DAK heating controllers, replaces power thyristors, reprograms microcontrollers, and restores display modules. All repairs include NIST-traceable calibration certificates for sensor input accuracy and thermal output verification. We perform functional validation under simulated process loads before dispatch.
What is the typical lifespan of a DAK cartridge heater, and when should I replace it?+
DAK cartridge heaters are engineered for 2000-5000 operating hours at rated wattage. Life extends with lower operating temperatures and reduces under thermal cycling stress or overload. Synchronics recommends replacement when insulation resistance drops below 2 megohms, element resistance drifts over 10 percent, or visible corrosion appears. Preventive replacement every 3-4 years is common in critical pharmaceutical processes.
Do you stock spare DAK heating elements and sensors for quick replacement?+
Synchronics maintains inventory of commonly repaired DAK cartridge heaters, immersion elements, Pt100 sensors, and thermocouple assemblies for immediate dispatch to Indian customers. For custom elements or large industrial oven heaters, we source OEM parts through authorized European distributors within 4-6 weeks. Emergency supply arrangements are available for production-critical applications.
How do I send my DAK 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 DAK 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 DAK 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 DAK 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.
