CURTIS Equipment We Repair — By Category
CURTIS Product Lines We Repair
Our engineers are trained on the full CURTIS product range. Below are the major product families we service.
Curtis Digital Compressor Controllers
Microprocessor-based control systems managing pressure setpoints, unload/load cycles, and motor soft-starters. Common issues: faulty pressure transducer signals causing erratic load switching, relay contact degradation in solenoid valve circuits, and calibration drift in setpoint regulators.
Curtis Variable Frequency Drives (VFD) for Compressors
Energy-saving motor speed control systems reducing compressor energy consumption by 30-40%. Repair focus: IGBT module failures from thermal cycling, capacitor bank failures, motor encoder communication loss, and firmware corruption causing speed regulation faults.
Curtis Aftercooler & Dryer Control Boards
Temperature and humidity regulation electronics for compressed air quality. Common faults: thermistor open-circuit, fan relay sticking, solenoid dump valve failures preventing condensate drainage, and display panel dead pixels.
Curtis Energy Monitoring Systems
kWh measurement and motor efficiency tracking boards. Repair issues: CT (current transformer) saturation causing measurement errors, data logging memory corruption, real-time clock battery failure, and Modbus communication protocol errors.
Curtis Solenoid Valve Solenoid Coils & Driver Circuits
12/24 VDC solenoid actuation for unload, load, and dump valve operation. Frequent failures: burnt coil windings from voltage spikes, relay contact welding, driver transistor shorts, and EMI-induced logic faults in adjacent circuits.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common CURTIS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CURTIS equipment arriving at our workshop.
- ✓Compressor locked in load position no unload — Curtis pressure transducer (PT-08 or equivalent) signal drift causes controller to misread system pressure. Solenoid unload valve driver relay contact burns out from sustained current, preventing valve energization.
- ✓Curtis VFD motor overspeed alarm F02 — Motor encoder cable disconnection or shorted shield to ground breaks speed feedback loop. Curtis drive firmware interprets zero encoder feedback as runaway speed condition, triggering safety shutdown.
- ✓Aftercooler fan runs continuously cannot modulate — Curtis thermistor temperature sensor becomes open-circuit due to moisture ingress or connector corrosion. Control board measures infinite resistance, defaulting fan to ON to prevent equipment overheating.
- ✓Condensate dump valve stuck open dryer outlet wet — Curtis solenoid dump valve plunger corroded by contaminated condensate, blocking closure. Alternatively, pilot drain line to solenoid cavity becomes plugged, preventing valve de-energization.
- ✓Curtis display panel blank no communication — RS-485 Modbus cable between main PCB and display panel corroded or crimped. Baud rate or node ID mismatch after firmware upload causes handshake failure.
- ✓Energy meter kWh counts erratically wrong consumption reading — Curtis CT (current transformer) secondary winding saturates due to DC bias from asymmetrical load or VFD harmonic current injection. Analog-to-digital converter in meter clamps to false values.

Frequently Asked Questions — CURTIS Repairs
Do you repair Curtis equipment anywhere in India?+
Yes. Synchronics is the Pan-India Curtis repair expert. We repair Curtis compressor controllers, variable frequency drives, aftercooler boards, solenoid valve electronics, and energy monitoring systems. Same-day courier pickup available from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Kolkata, and tier-2 cities. All repairs completed in our Vadodara, Gujarat facility and returned by insured courier.
My Curtis compressor is stuck in load mode and consuming power continuously. What is the most likely cause?+
The Curtis pressure transducer (PT-08) has typically drifted out of calibration, or the unload solenoid valve solenoid driver relay has failed. When the controller cannot read system pressure accurately, it cannot command the unload valve to vent to atmosphere. Synchronics tests the transducer output and replaces it if it reads outside ±2% accuracy. We also inspect the solenoid driver relay contacts and replace burnt contacts immediately.
What is the typical turnaround time for Curtis controller repair at Synchronics?+
Most Curtis controller repairs — pressure transducer replacement, relay contact service, solenoid coil testing — are completed in 5-7 working days. If firmware reprogramming or EEPROM data recovery is required, allow 7-10 days. We provide daily repair status updates via email and expedited turnaround on standby/critical-path equipment at no extra charge.
Can you repair Curtis VFD drives or only the mechanical solenoid-based controllers?+
Synchronics repairs both. Our team specializes in Curtis variable frequency drives (VFD-75, VFD-110, VFD-150 models) — IGBT module replacement, capacitor bank service, encoder reconnection, and firmware restoration. We also repair microprocessor-based Curtis digital controllers (DK4000, DK6000 series). Component-level diagnostics identify root causes, not just symptom-level fixes.
Do you stock Curtis spare parts or do I need to supply them?+
We source genuine OEM Curtis components — pressure transducers, solenoid coils, relay modules, IGBT drivers, and capacitors — through our authorized supplier network. Most parts are available in 2-3 working days. If you have surplus Curtis parts or prefer to supply components, we accept them and charge only labor and test costs. All repairs include 12-month warranty on replaced components.
How do I send my CURTIS 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 CURTIS 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 CURTIS 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 CURTIS 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.
