DILO Equipment We Repair — By Category
DILO Product Lines We Repair
Our engineers are trained on the full DILO product range. Below are the major product families we service.
DILO Gas Recovery Units (GRU)
DILO GRU systems recover, recycle, and purify SF6 gas from high-voltage switchgear during maintenance and decommissioning. Common issues include pump seal failures, moisture ingress in filter cartridges, pressure regulator drift, and compressor bearing wear affecting gas purity and recovery efficiency.
DILO Moisture Analysers and Diagnostic Systems
DILO moisture analysers measure water vapour content in SF6 gas to ensure switchgear insulation integrity. Typical faults include sensor calibration errors, display PCB corrosion, serial communication failures, and drift in humidity measurement readings impacting maintenance schedules.
DILO High-Voltage Switchgear Monitoring Systems
Integrated condition monitoring and control modules for GIS equipment. Repair needs centre on relay contact wear, digital interface card failures, real-time gas quality monitoring sensor faults, and communication protocol errors in networked substations.
DILO SF6 Gas Filling and Handling Trolleys
Mobile or stationary trolleys for SF6 gas transfer, filtration, and metering at substations and switchyards. Common failures include pressure gauge accuracy loss, flow meter malfunction, solenoid valve sticking, and hose connector leakage reducing operational efficiency.
DILO Purity Testing and Decomposition Analysis Equipment
Laboratory-grade systems for SF6 decomposition analysis and purity certification prior to equipment commissioning. Failures typically involve gas chromatography detector drift, sample inlet contamination, calibration gas regulator malfunction, and data logging system corruption.

Common DILO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DILO equipment arriving at our workshop.
- ✓DILO GRU pump seal leakage and gas loss — Continuous operation without maintenance degrades dynamic seals in DILO GRU compressor units. High-pressure cycling and exposure to residual moisture accelerate seal wear, leading to SF6 gas escape and reduced recovery capacity.
- ✓DILO moisture analyser sensor drift and false readings — MIXTROL capacitive moisture sensors degrade after years of exposure to SF6 gas, especially in high-humidity environments common in Indian monsoon seasons. Contamination inside the sensor electrode chamber causes calibration shift and unreliable alarm thresholds.
- ✓DILO GRU filter cartridge saturation and clogging — Moisture and particulate contamination in SF6 gas saturates DILO's desiccant and activated carbon filter cartridges faster in dusty Indian industrial environments. Clogged filters increase pump back-pressure, reduce gas flow rates, and force system shutdown during critical switchyard maintenance windows.
- ✓DILO switchgear monitoring system PCB corrosion and display failure — DMS-100 and DMS-200 display and control PCBs suffer electrochemical corrosion in high-humidity substation environments, especially near coastal or industrial areas with salt-laden air. Solder joint cracks and component pad delamination interrupt signal transmission and cause intermittent or complete display blackout.
- ✓DILO pressure regulator creep and gauge inaccuracy in GRU systems — DILO precision pressure regulators in gas recovery units experience internal spool drift due to spring fatigue and contamination ingress over 5-10 years of operation. Gauge needle calibration drift shows false pressure readings, misleading technicians about actual gas purity and system safety margins.
- ✓DILO gas chromatography detector baseline drift in decomposition analysers — Extended operation without preventive maintenance contaminates the thermal conductivity detector (TCD) or flame ionisation detector (FID) filament in DILO decomposition analysers. Column coating degradation and carrier gas line blockages degrade peak resolution, producing unreliable decomposition product measurements.

Frequently Asked Questions — DILO Repairs
Do you repair DILO equipment anywhere in India?+
Yes. Synchronics repairs the full DILO product range — gas recovery units (GRU), moisture analysers (MIXTROL), switchgear monitoring systems (DMS), and SF6 diagnostic equipment. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. All repairs are completed in our ISO 9001 facility in Vadodara, Gujarat, with same-day turnaround for critical substation equipment.
Can Synchronics certify DILO gas recovery unit repairs for utility compliance?+
Yes. All DILO GRU repairs undergo pressure cycle testing, gas purity verification, and performance certification. We document seal integrity, pump flow rates, filter efficiency, and regulator accuracy with test reports compatible with Indian electrical utility standards (CEA, state SEB audit requirements). Our certification is accepted by major power distribution utilities across India.
What is the typical turnaround time for DILO moisture analyser repair?+
DILO MIXTROL-P and MIXTROL-K moisture sensor repairs typically take 5-7 working days. This includes sensor replacement or calibration, PCB cleaning (if corrosion present), display module testing, and full humidity range validation. Critical switchyard equipment can be expedited to 2-3 days. We keep common DILO sensor and display modules in stock at Vadodara.
Does Synchronics stock genuine DILO spare parts?+
Yes. We maintain an extensive inventory of DILO OEM spare parts including filter cartridges, pressure regulators, moisture sensors, solenoid valve assemblies, and pressure gauges for GRU and monitoring systems. We also source additional parts directly from DILO Germany when required. All spares are verified for authenticity and compatibility before use in repairs.
Can you repair DILO decomposition analysers used for SF6 purity testing?+
Yes. Synchronics repairs DILO SF6 decomposition analysers, Rapidox 5100 moisture monitors, and complete gas purity testing systems. We recalibrate detector baselines, replace contaminated columns, service carrier gas flow systems, and validate all measurements against certified reference standards. This is critical for utilities commissioning new GIS equipment or certifying existing switchgear compliance with IEC 60480 purity limits.
How do I send my DILO 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 DILO 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 DILO 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 DILO 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.
