ALFA-LAVAL Equipment We Repair — By Category
ALFA-LAVAL Product Lines We Repair
Our engineers are trained on the full ALFA-LAVAL product range. Below are the major product families we service.
Plate Heat Exchanger Control Systems
Electronic controllers for Alfa Laval PHE units manage flow rate, temperature, and pressure in dairy, pharma, and chemical plants. Common faults include temperature sensor drift, solenoid valve control failures, and circuit board corrosion from ammonia-based coolants.
Centrifugal Separator Drive Electronics
Variable frequency drive (VFD) systems and control modules for Alfa Laval centrifugal separators used in oil refining, dairy processing, and biodiesel production. Repairs include bearing vibration monitoring failures, bearing slip ring damage, and separator bowl acceleration faults.
Membrane Separation Automation Modules
Programmable logic controllers (PLCs) and sensor signal conditioning boards managing reverse osmosis, ultrafiltration, and microfiltration systems in Indian water treatment and food processing. Common issues include transmitter signal loss, membrane pressure transducer failures, and inlet valve solenoid faults.
Gasketed Plate Frame Heat Exchanger Electronics
Temperature regulation and safety interlock systems for Alfa Laval GPE/GPC series units. Critical in HVAC, refrigeration, and industrial cooling loops. Faults often involve thermistor failures, relay stiction, and condensation damage to terminal blocks.
Booster Pump and Circulation Drive Control
Motor starting, soft-start, and frequency conversion electronics for Alfa Laval circulation pumps in thermocompressor and waste heat recovery systems. Repairs address capacitor breakdown, phase-sensing relay faults, and pump cavitation detection sensor errors.

Common ALFA-LAVAL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ALFA-LAVAL equipment arriving at our workshop.
- ✓Plate heat exchanger temperature sensor drift and calibration loss — Alfa Laval PT100 and PT1000 resistance temperature detectors (RTDs) in PHE manifolds experience drift due to vibration, thermal cycling, and exposure to process fluids (milk, oil, ammonia). Sensor bridge circuits in the controller degrade, causing incorrect temperature readings and energy loss.
- ✓Centrifugal separator bowl acceleration failure - slip ring signal loss — Alfa Laval separator slip rings accumulate salt and protein residue during continuous operation, causing intermittent electrical contact. Control electronics misinterpret the bowl speed ramp rate, preventing proper separator start-up or creating bowl acceleration timeout errors.
- ✓Solenoid valve control non-response in product discharge circuits — Milk fat, oil residue, and mineral scale buildup inside Alfa Laval solenoid valves increases coil resistance and reduces magnetic force. The control board's solenoid driver output stage suffers from voltage droop, preventing valve actuation in dairy and food processing lines.
- ✓Membrane system pressure transmitter failure and 4-20mA signal loss — Alfa Laval RO and UF system pressure transducers experience zero-shift and hysteresis due to crystallization of salts on diaphragms and corrosion of the 4-20mA signal conditioning circuit. Microcontroller ADC channels fail to recognize valid pressure readings.
- ✓Thermistor open circuit in gasketed plate frame safety interlocks — Alfa Laval GPE/GPC series thermistors used in thermal cutoff circuits experience open-circuit failures due to vibration and flexing of lead wires during freeze-thaw cycling. Missing temperature feedback prevents automatic restart after high-temperature shutdown.
- ✓Capacitor failure and soft-starter malfunction in pump drive control — Aluminum electrolytic capacitors in Alfa Laval booster pump soft-starters dry out under continuous thermal stress (40-55 degC ambient in Indian plants). Capacitor ESR rises, reducing soft-start current ramp smoothness and causing motor inrush spikes.

Frequently Asked Questions — ALFA-LAVAL Repairs
Do you repair Alfa Laval equipment anywhere in India?+
Yes. Synchronics repairs the complete Alfa Laval electronics product range - plate heat exchanger controllers, centrifugal separator drive modules, membrane system PLCs, and booster pump soft-starters. We offer PAN-India door pickup service from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all major industrial cities. All repairs are done in our 25,000+ sq.ft. facility in Vadodara, Gujarat, with rapid turnaround (5-10 days for most faults).
What is the typical repair cost for an Alfa Laval heat exchanger controller?+
Repair costs vary based on fault severity and component replacement needs. Simple recalibration or sensor replacement typically costs INR 8,000-15,000. Board-level repairs involving capacitor replacement or IC component swapping range from INR 12,000-28,000. Full board replacement or multi-module failures run INR 25,000-45,000. Synchronics provides upfront quotation after fault diagnosis and uses OEM-equivalent industrial components with 12-month warranty on all repairs.
How do I know if my Alfa Laval separator is experiencing electronics failure versus mechanical wear?+
Common electronics failure signs: bowl does not accelerate smoothly, control display shows no temperature reading, solenoid valve does not open/close, or 4-20mA transmitter signal is stuck at min/max. Synchronics performs non-destructive electronics diagnosis - we bench-test sensor inputs, solenoid coil resistance, relay contacts, and signal conditioning circuits. If the electronics checks pass, the issue is likely mechanical (bearing wear, bowl imbalance, seal degradation) requiring Alfa Laval mechanical service.
Can Synchronics repair Alfa Laval PLC and automation modules?+
Yes. We repair Alfa Laval MicroControl PLC modules, MembraneGuard monitors, FlowKeeper sensor units, and all associated I/O interface boards. Common repairs include thermistor replacement, RTD signal conditioning, solenoid driver relay replacement, and PLC input/output module repair. We also provide PLC programming re-commissioning and sensor re-calibration after board repair to restore full system functionality.
What warranty do you provide on Alfa Laval electronics repairs?+
Synchronics provides a 12-month comprehensive warranty on all component repairs and replacements, covering defects in workmanship and material failure under normal operating conditions. Warranty does not cover damage from electrical overstress, lightning, or mechanical shock. We also offer optional extended 18/24-month warranties for mission-critical applications in dairies, refineries, and power plants. All repairs come with detailed test reports and component traceability.
How do I send my ALFA-LAVAL 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 ALFA-LAVAL 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 ALFA-LAVAL 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 ALFA-LAVAL 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.
