BLOHM Product Lines We Repair
Our engineers are trained on the full BLOHM product range. Below are the major product families we service.
Blohm Temperature Controllers
Digital and analog temperature control modules for process heating. Common faults include display failures, sensor signal loss, and PID tuning drift in high-temperature pharmaceutical and chemical applications. Synchronics repairs the full controller range including legacy and current models with complete recalibration.
Blohm Thyristor Power Packs
High-current thyristor modules controlling heating element power in injection molding and extrusion lines. Repair challenges include thyristor bridge faults, cooling fan failures, and logic board degradation from thermal cycling. Synchronics stocks replacement thyristor bridges and performs full load testing.
Blohm Heating Element Assemblies
Industrial-grade immersion and cartridge heaters with integrated terminal blocks. Common issues are open-circuit coils, terminal corrosion in humid environments, and insulation breakdown. Synchronics performs winding resistance testing and provides hot-swap replacement assemblies.
Blohm PID Tuning Modules
Proportional-integral-derivative control cards for precise temperature stability in pharmaceuticals and food processing. Failures stem from capacitor aging, sensor interface circuit faults, and firmware corruption. Synchronics recalibrates sensor inputs and reprograms control logic.
Blohm Sensor Interface Modules
RTD and thermocouple signal conditioning cards for Pt100 and K-type inputs. Common faults include bridge amplifier drift, reference voltage instability, and connector oxidation in high-humidity mills. Synchronics performs full analog circuit repair and sensor calibration.
Blohm Relay Output Modules
Logic relay cards and soft-start modules for actuator control and load switching. Repair issues include relay contact welding, optoisolator failures, and control logic circuit faults in packaging and textile machinery. Synchronics provides relay replacement and circuit-level diagnostics.

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 BLOHM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BLOHM equipment arriving at our workshop.
- ✓Blohm controller display blank or flickering — LCD panel degradation, backlight inverter failure, or loose ribbon cable connection caused by thermal expansion and contraction in high-temperature plant environments. Moisture ingress into display connectors also common in humid Indian manufacturing units.
- ✓Blohm temperature reading stuck or drifting — RTD sensor wire breakage inside the thermowell, thermocouple cold-junction compensation circuit failure, or sensor interface amplifier IC degradation. Common in plastics extrusion plants where process liquids corrode sensor connections.
- ✓Blohm thyristor power pack no heating output — Open-circuit thyristor in the bridge rectifier, failed gate drive optoisolator, or logic board firmware corruption preventing gate pulse generation. Thermal cycling in metal die casting and injection molding facilities accelerates thyristor junction failures.
- ✓Blohm PID controller overshooting or oscillating temperature — Incorrect PID tuning parameters stored in EEPROM, sensor signal noise due to poor shielding near high-current drives, or integral/derivative time constants not matched to process thermal lag. Pharmaceutical batch processing especially sensitive to tuning drift.
- ✓Blohm relay output card sticking or failing to switch — Relay contacts welded due to inductive load spike without snubber diode, or optoisolator LED aging reducing gate drive signal. Mechanical relay fatigue after millions of cycles in continuous-duty chemical dosing or packaging line applications.
- ✓Blohm sensor interface module reading noise or instability — Loose RTD or thermocouple connector causing intermittent contact resistance, 50 Hz mains pickup in unshielded sensor cable running alongside power lines, or amplifier reference voltage regulator capacitor dried out. Textile mills and metal processing plants especially prone to EMI.

Frequently Asked Questions — BLOHM Repairs
Do you repair Blohm equipment anywhere in India?+
Yes. Synchronics repairs the full Blohm product range - temperature controllers, thyristor power packs, heating element assemblies, PID modules, and relay cards. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Vadodara, and all other cities. Same facility in Vadodara, Gujarat where 180+ engineers handle Blohm repairs with thermal test facilities and calibration equipment.
What is Blohm PID controller tuning and why does it fail?+
PID (Proportional-Integral-Derivative) tuning is the core algorithm inside Blohm controllers that maintains setpoint temperature by adjusting heating output. Tuning parameters drift or corrupt due to power surges, firmware corruption, or capacitor aging in the control card. Synchronics uses industry-standard relay-feedback auto-tuning methods to restore optimal performance, then documents the tuning coefficients for your process.
How do Blohm thyristor modules fail and what is the repair timeline?+
Blohm thyristor power packs fail when the silicon thyristor junction opens or gates fail to trigger, stopping all heating output. Gate drive optoisolators age and reduce signal strength. Synchronics stocks replacement thyristor bridges and reprograms gate logic within 3-5 working days including thermal load-bank testing at rated amperage.
Can Synchronics provide calibration certificates for Blohm temperature controllers?+
Yes. Synchronics performs full thermal calibration of Blohm controllers using NIST-traceable calibration blocks and thermal bath equipment at Vadodara facility. We issue calibration certificates showing pre-repair and post-repair sensor accuracy across your operating temperature range, required for pharma GMP and food safety compliance in Indian manufacturing.
What causes Blohm sensor reading errors in high-humidity chemical plants?+
Blohm RTD and thermocouple connections corrode and develop intermittent contact resistance when exposed to chlorine vapors, ammonia, or salt spray in coastal chemical facilities. Moisture ingress into connector pins causes oxidation. Synchronics replaces all connectors with stainless-steel or gold-plated contacts, applies silicone sealant, and uses shielded twisted-pair sensor cabling to reject mains interference common in Indian chemical plants.
How do I send my BLOHM 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 BLOHM 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 BLOHM 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 BLOHM 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.
