CHROMALOX Product Lines We Repair
Our engineers are trained on the full CHROMALOX product range. Below are the major product families we service.
Chromalox Immersion Heaters
Electric immersion heaters used in tanks, vessels, and process streams. Common failures include element burnout due to low liquid level, thermostat failure, terminal corrosion, and control board short circuits. Temperature sensing degradation is frequent in high-salinity or corrosive environments.
Chromalox Duct Heaters
Industrial air heating systems for HVAC, dryers, and process air applications. Failure modes include element breakage from thermal shock, airflow blockage, control thermostat drift, and contactor burnout. Humidity and dust ingress in Indian humid climates accelerate deterioration.
Chromalox Process Heating Controllers
Standalone and panel-mount temperature control systems with PID logic. Common faults include sensor input failure, proportional valve solenoid malfunction, relay and contactor fatigue, and calibration drift. Power supply board failures occur in high-vibration industrial environments.
Chromalox SCR Power Controllers
Silicon-controlled rectifier modules for variable power control to heating elements. Failures include SCR gating circuit faults, snubber capacitor failure, thyristor short circuits, and firing angle control instability. Heat sink corrosion is common in coastal or chemically aggressive plants.
Chromalox Thermal Sensors and RTDs
Platinum resistance thermometers and thermocouples integrated with Chromalox heating systems. Common issues include sensor junction oxidation, lead wire insulation breakdown, cold-junction compensation failure, and transmitter calibration loss due to thermal cycling stress.
Chromalox Industrial Heat Exchanger Heaters
Integrated heating systems for heat recovery and process fluid warming. Typical faults include scale buildup on element surfaces, internal corrosion leakage, control valve blockage, and bypass thermostat failure. Indian water quality and mineral content accelerate fouling.

Common CHROMALOX Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CHROMALOX equipment arriving at our workshop.
- ✓Immersion heater element open circuit failure — Chromalox immersion heating elements burn out due to insufficient liquid level, loss of process fluid, or prolonged dry-run operation. Thermal stress from rapid temperature cycling in seasonal Indian climates also causes wire brittleness and fracture.
- ✓SCR controller thyristor short circuit — Chromalox SCR power modules suffer thyristor gate-cathode shorts from overvoltage transients, moisture infiltration, or thermal fatigue. Inadequate snubber capacitor ratings and poor heat dissipation in dusty Indian factory environments accelerate failure.
- ✓Temperature sensor reading drift and calibration loss — Chromalox RTD sensors and thermocouples develop junction oxidation, lead-wire insulation degradation, or transmitter calibration offset after years of thermal cycling. High-temperature process environments and chemical process vapors cause sensor head corrosion.
- ✓Control thermostat sticking and hunt cycling — Chromalox built-in thermostats mechanically stick or calibrate inaccurately due to mineral deposits in liquid heater applications, thermal cycling stress, or contact burnout from high switching currents. Setpoint drift causes temperature overshoot and equipment hunting.
- ✓Duct heater contactor chattering and element burnout — Chromalox duct heaters experience contactor chatter from line voltage sag, inadequate control transformer capacity, or load inrush current spikes. This causes intermittent element heating and accelerated thermal fatigue in high-volume air applications.
- ✓Power supply board failure and blown fuses — Chromalox control panels suffer power supply failures from rectifier diode failures, electrolytic capacitor drying, or transient voltage spikes entering from plant electrical distribution. Inadequate input power conditioning in Indian industrial facilities increases component stress.

Frequently Asked Questions — CHROMALOX Repairs
Do you repair Chromalox immersion heaters and duct heaters anywhere in India?+
Yes. Synchronics repairs the complete Chromalox heating equipment portfolio — immersion heaters, duct heaters, process heating controllers, SCR power modules, and thermal sensors. We offer pan-India door pickup and courier from Vadodara, Gujarat. We serve Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all industrial cities. Most repairs are completed within 5-7 working days.
What is the typical cause of Chromalox immersion heater burnout in Indian plants?+
Chromalox immersion heaters fail most often due to low liquid level operation, loss of process fluid circulation, or thermostat malfunction allowing dry-firing. In coastal and chemically aggressive plants, corrosion of the sheath and terminal leads shortens service life. Synchronics recommends installing low-level cutoff interlocks and annual preventive maintenance to extend element life from 3 to 5+ years.
Can Synchronics recalibrate Chromalox temperature controllers and sensors?+
Yes. Synchronics offers full recalibration and adjustment of Chromalox analog and digital temperature controllers, RTD transmitters, and thermostat setpoints. We use calibrated instrumentation traceable to national standards. We also troubleshoot PID tuning issues and modify control logic to improve process temperature stability and reduce oscillation in high-inertia heating applications.
How do I prevent Chromalox SCR controller failure?+
Synchronics recommends regular inspection of SCR module heat sinks for dust and corrosion buildup, replacement of filter capacitors every 4-5 years, and input power conditioning using isolation transformers or UPS systems. We also test snubber capacitors annually and replace them before failure. Proper heatsink temperature management and thermal cycling control significantly extend SCR controller life.
What is your warranty on Chromalox repairs?+
Synchronics provides 12 months parts and labour warranty on all Chromalox equipment repairs. We use genuine Chromalox spares where available and high-grade industrial alternatives certified to equivalent performance standards. Emergency repairs and expedited 24-48 hour turnaround are available for critical petrochemical and power generation applications across India.
How do I send my CHROMALOX unit for repair?+

What is the cost of repairing a CHROMALOX 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 CHROMALOX 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 CHROMALOX 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.
