GWK Product Lines We Repair
Our engineers are trained on the full GWK product range. Below are the major product families we service.
Compact Chillers (WSK, WTK series)
Compact, wall-mounted or floor-standing water coolers for small to medium production areas. Common issues include refrigerant leakage, compressor bearing wear, and thermostat sensor drift affecting temperature accuracy within ±0.5K tolerance windows.
Modular Chilling Systems (SLK, SLK XT)
Stackable, scalable cooling modules for large production facilities and process loops. Failures typically involve heat exchanger fouling, expansion valve icing, and loss of PLC communication between master and slave units in cascade configurations.
Precision Temperature Controllers (TS, TSX series)
Standalone or integrated controllers managing multiple cooling loops with ±0.1K stability for cleanrooms and semiconductor processes. Repair focuses on sensor calibration drift, relay contact erosion, and PID loop tuning failures after power surges.
High-Performance Chillers (WK series)
Industrial-grade chillers for continuous 24/7 operation in automotive component testing, pharmaceutical batch cooling, and chemical synthesis. Common faults include oil circulation problems in semi-hermetic compressors, capacitor bank failures, and loss of subcooling in the refrigerant circuit.
Control Electronics (KS, KSX display units)
Touchscreen and button-operated interface modules for GWK chillers with integrated data logging and alarm management. Typical failures: display pixel dropout, membrane keypad debouncing issues, and EEPROM corruption after mains voltage transients.

Common GWK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GWK equipment arriving at our workshop.
- ✓Loss of cooling output / reduced chiller capacity — GWK compressors suffer from refrigerant circuit restrictions due to sludge buildup in the oil or frozen expansion valve orifices, especially in monsoon-heavy Indian climates where moisture ingress is common. Low subcooling or superheat readings confirm blockage.
- ✓Temperature sensor reading instability / erratic display — GWK temperature probes (Pt100 RTD or NTC thermistor types) develop signal drift due to sensor contact corrosion in aggressive coolant environments or loose connector pins. Moisture inside the probe sheath causes intermittent open-circuit faults.
- ✓Compressor not starting / motor hum without rotation — GWK semi-hermetic and hermetic compressors jam due to liquid slugging (unvaporized refrigerant entering the compressor chamber), oil starvation from low oil levels, or three-phase winding short-circuits from thermal overstress during monsoon humidity spikes.
- ✓PLC / control board display blank or frozen screen — GWK control boards suffer from capacitor dry-out in high-temperature equipment rooms (>40C ambient common in Indian plant floors), power supply noise from nearby VFDs/welders, or corrosion of PCB traces from condensation in non-AC rooms.
- ✓High-pressure cutout alarm / system shutdown cycles — GWK pressure transducers or relief valve spools stick due to mineral deposits in glycol-based coolants (common in Indian recycled water systems). Blocked condenser tubes or fan motor failure reduce heat rejection, causing pressure creep.
- ✓Compressor short-cycles / runs frequently with poor cooling — GWK thermostat contacts wear or stick in the neutral position, preventing proper ON/OFF switching. Expansion valve hunting (rapid opening/closing) from undersizing or hunting oscillations also causes short-cycling and temperature swings beyond tolerance.

Frequently Asked Questions — GWK Repairs
Do you repair GWK equipment anywhere in India?+
Yes. Synchronics repairs the full GWK product range including compact chillers, modular systems, temperature controllers, and control electronics. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major cities. All repairs are performed at our central facility in Vadodara, Gujarat, with typical turnaround of 5-10 working days for standard repairs, and 24-48 hours for emergency breakdowns.
What is the most common failure in GWK chillers in Indian factories?+
Refrigerant circuit blockages due to moisture and sludge contamination are the leading fault we see. This is amplified by India's high humidity, intermittent power supplies causing compressor cycling stress, and use of non-OEM refrigerants. Preventive maintenance every 18 months—including filter dryer replacement, acid number testing, and oil analysis—prevents 80% of GWK failures in Indian plants.
Can you calibrate GWK temperature sensors and control loops on-site?+
Yes. Synchronics provides on-site calibration and commissioning services for GWK systems. We bring calibrated reference blocks, multifunction meters, and GWK configuration software to verify sensor accuracy within ±0.1K and validate PID tuning parameters. We also provide customer training on alarm codes, preventive maintenance schedules, and alarm response procedures.
Do you stock GWK spare parts?+
We maintain a working stock of high-failure GWK components including filter dryers, expansion valves, thermostats, pressure transducers, capacitors, and thermal probes. For larger items (compressors, heat exchangers, control boards), we source OEM and equivalent parts via our supplier network within 2-3 working days. All parts carry replacement warranty.
What documents do I need to send for GWK repair?+
Send the equipment nameplate photo, fault description, and any error codes or alarms displayed. If available, maintenance logs and previous repair records help us diagnose faster. Once we receive the unit, we perform full system testing, provide a detailed diagnostic report with repair quote, and proceed only after your written approval.
How do I send my GWK 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 GWK 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 GWK 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 GWK 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.
