SCHUBERT & SALZER Equipment We Repair — By Category
SCHUBERT & SALZER Product Lines We Repair
Our engineers are trained on the full SCHUBERT & SALZER product range. Below are the major product families we service.
Coalescer Control Systems
Schubert & Salzer coalescer units with integrated electronic control and differential pressure monitoring. Common repair issues include stuck solenoid valves, failed pressure transducers, and corroded control board connectors in humid industrial environments.
Filter Management Electronics
PLC-based and analog control modules for multi-stage filtration systems. Typical faults include clogged filter element signal loss, relay chatter on bypass valves, and communication breakdowns between filter cartridges and master control units.
Separation Equipment Control Boards
Dedicated electronics for oil-water and liquid-liquid separation systems. Prone to capacitor degradation in high-temperature refineries, relay failure under motor starting load transients, and corroded terminal blocks from aggressive chemical vapors.
Condition Monitoring Interfaces
Remote monitoring and diagnostics modules for large-scale separation installations. Faults include broken Ethernet jacks, failed power supply modules, and calibration loss of differential pressure and temperature sensors after power surges.

Common SCHUBERT & SALZER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SCHUBERT & SALZER equipment arriving at our workshop.
- ✓Solenoid valve stuck in coalescer drain circuit — Schubert & Salzer coalescers operate in harsh fluid environments where mineral deposits and corrosion internally lock solenoid plungers. Humidity in motor terminals prevents proper coil demagnetization, holding the valve open or closed permanently.
- ✓Differential pressure transducer signal loss or drifting readings — Schubert & Salzer filter and coalescer units expose pressure sensors to pulsating fluid systems and temperature swings. Sensor diaphragm rupture, blocked impulse lines, or connector corrosion in Gulf humidity regions causes reading loss or erratic filter bypass signals.
- ✓PLC analog input module failure in filter management system — Schubert & Salzer filter control PLCs operate in electrically noisy refineries where motor starters and pump drives create high-frequency noise. Input card isolation fails, and surge energy damages the ADC circuit, causing false pressure readings and unwarranted filter element bypass commands.
- ✓Relay chatter and contact erosion on bypass solenoid driver — Schubert & Salzer separation systems must pulse bypass solenoids rapidly when filter pressure spikes occur. Insufficient contact pressure in relay contacts, combined with inductive kickback from solenoid coils, causes rapid contact bounce, arcing, and eventual failure to energize the bypass.
- ✓Ethernet communication loss on remote monitoring gateway — Schubert & Salzer condition monitoring gateways in outdoor skids or cable tray installations suffer broken RJ45 connectors from vibration, corrosion of the PCB Ethernet jack from salt spray in coastal refineries, or failed isolation transformer secondary windings.
- ✓Capacitor swelling and power supply voltage regulation failure — Schubert & Salzer control electronics in tropical Indian petrochemical plants experience high ambient temperatures (40-50°C) where aluminum electrolytic capacitors degrade rapidly. Overvoltage transients from pump motor switching accelerate capacitor aging, causing voltage rails to sag and reset PLC programs unexpectedly.

Frequently Asked Questions — SCHUBERT & SALZER Repairs
Do you repair Schubert & Salzer equipment anywhere in India?+
Yes. Synchronics Electronics repairs the complete Schubert & Salzer product range — coalescers, filter management systems, separation equipment electronics, and condition monitoring gateways. We offer pan-India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all other major cities. All repairs are completed in our Vadodara, Gujarat facility with turnaround times of 5-10 working days for most faults.
My Schubert & Salzer coalescer is cycling the bypass solenoid continuously. What causes this?+
Continuous solenoid cycling in a Schubert & Salzer coalescer typically indicates a stuck or drifting differential pressure transducer, incorrect PLC gain tuning, or a failing solenoid valve that cannot fully close. Synchronics will bench-test your transducer output, recalibrate the PLC control algorithm, and replace the solenoid if necessary. We often find that routine inlet filter clogging triggers false high-pressure signals — we inspect and upgrade your inlet strainer design to prevent recurrence.
Can Synchronics repair legacy Schubert & Salzer analog control boards from older separation skids?+
Absolutely. Synchronics has extensive experience repairing Schubert & Salzer analog relay and potentiometer-based control modules used in 1990s and 2000s separation systems. We stock replacement relays, timers, and terminal blocks compatible with your legacy board, and we can rebuild failed op-amp circuits and power supplies. For plants running 24/7 operations, we offer expedited 2-3 day turnaround on analog board repairs.
What warranty do you provide on Schubert & Salzer repairs?+
Synchronics provides a 12-month parts and labor warranty on all Schubert & Salzer repairs — both component replacements and reprogrammed electronics. We test every repair on Schubert & Salzer test benches simulating your actual operating conditions (fluid type, temperature, pressure, duty cycle) before shipment. If a fault recurs within warranty, we repair or replace the unit at no charge and cover return courier costs.
How do I know if my Schubert & Salzer control module is worth repairing versus replacing?+
Synchronics provides a free diagnostic evaluation of your Schubert & Salzer module within 48 hours of receipt. We identify the root fault, provide a repair cost estimate, and compare it to new replacement pricing from Schubert & Salzer distributors. For most Indian plants, repair of Schubert & Salzer electronics costs 40-60% less than replacement and takes 1-2 weeks instead of 4-8 weeks for import. We recommend repair for units under 10 years old with repairable faults (capacitor failure, relay stiction, connector corrosion) and replacement only for obsolete or irreparably damaged modules.
How do I send my SCHUBERT & SALZER 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 SCHUBERT & SALZER 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 SCHUBERT & SALZER 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 SCHUBERT & SALZER 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.
