Generator Servicing
Regular servicing is the single most effective way to extend your generator's lifespan and prevent unexpected breakdowns. Our comprehensive service covers oil and filter changes, coolant inspection, belt checks, battery testing, and a full load test — available across all Gauteng regions.
- Full oil and filter change with quality-spec lubricants
- Coolant system inspection and top-up
- Air and fuel filter replacement
- Battery and charging system check
Maintenance Plans
A maintenance plan removes the guesswork entirely. We track your generator's service intervals, contact you when it's due, and handle everything from scheduling to paperwork. Businesses and property managers across Gauteng rely on our contracts to keep standby systems ready for loadshedding.
- Customised service schedules by hours run or calendar interval
- Priority callout response for contracted clients
- Full service records and compliance documentation
- Discounted rates on parts and emergency callouts
Emergency Callouts
When your generator fails mid-loadshedding or during a critical power event, every minute counts. Our emergency response team is deployed across Gauteng — Johannesburg, Pretoria, Midrand, Centurion and beyond — with most callouts receiving an on-site technician within 2–4 hours.
- Same-day emergency callouts across all of Gauteng
- Mobile workshops stocked with common failure parts
- Priority dispatch for contracted maintenance clients
- Available for residential, commercial and industrial emergencies
Generator Installation
A professional installation is critical to the safety and longevity of your generator. Our team handles the complete process: site assessment, foundation or mounting, fuel line installation, electrical connections, changeover switch wiring, and commissioning. All work complies with SANS standards.
- Site assessment and generator sizing advice
- Automatic and manual changeover switch installation
- Fuel tank and supply line installation
- SANS-compliant electrical connections
Load Bank Testing
Standby generators that rarely run under full load accumulate wet stacking — unburned fuel deposits in the exhaust system — reducing efficiency and causing premature failure. Load bank testing applies a controlled electrical load, verifying rated output and clearing wet stacking. Compliance documentation provided.
- Tests generator at 50%, 75% and 100% rated capacity
- Clears wet stacking in diesel generators
- Provides compliance documentation for insurers
- Identifies capacity shortfalls before they become emergencies
AVR & Voltage Regulator Repairs
A faulty Automatic Voltage Regulator causes fluctuating or incorrect output voltage, which can damage connected equipment. Our technicians diagnose AVR faults, replace failed units with quality-matched components, and test voltage stability under load to confirm clean, consistent power output.
- Diagnosis of voltage fluctuation and instability faults
- AVR replacement with OEM-spec or quality aftermarket units
- Voltage output testing under varying load conditions
- Applicable to all generator brands and alternator types
Control Panel Repairs
Modern generators rely on digital control panels and AMF (Automatic Main Failure) controllers to manage automatic starting and load transfer. When these systems fault, your generator may fail to start during loadshedding. We repair, reprogram and replace control panels across all major controller brands.
- AMF and ATS controller diagnosis and repair
- DSE, ComAp, Deepsea and SmartGen controller support
- Relay, fuse and circuit board replacement
- Full auto-start and shutdown cycle testing
Fuel System Repairs
Diesel degradation, water contamination, and blocked injectors are among the most common causes of generator failure in South Africa. Our fuel system service covers fuel polishing, injector cleaning and replacement, lift pump and injection pump repairs, and fuel tank cleaning.
- Fuel polishing and contamination removal
- Injector cleaning, testing and replacement
- Fuel lift pump and injection pump repairs
- Fuel tank inspection and internal cleaning
Generator Rewinding
When a generator alternator suffers winding failure — from insulation breakdown, overloading, or moisture ingress — rewinding is often the most cost-effective solution. Our workshop rewinds stators and rotors to factory specifications with full insulation resistance testing before return.
- Stator and rotor rewinding to OEM specifications
- Insulation resistance testing before and after rewind
- Suitable for all alternator brands and frame sizes
- Often 40–60% cheaper than full alternator replacement
