Rosslyn sites
Generators we work on in Rosslyn
Vehicle assembly plants: Industrial generator services
Large plant-room standby systems carrying conveyors, lighting and the controls that keep a line moving.
Automotive component makers: Voltage problems
Three-phase sets behind presses, compressors and assembly cells at the Supplier Park firms that feed the vehicle plants.
Klerksoord factory and warehouse units: ATS and changeover problems
Older units, such as those on Diamant Road, where the set and its changeover panel may be as old as the building.
Workshops and engineering works: Single vs three phase
Welders, lathes and compressors on one set, often loaded unevenly across its three phases.
Warehouses and logistics: Commercial generator services
Sets that carry dock doors, lighting, scanners and the dispatch office, and stand unused between outages.
Industrial parks: Standby generators
Shared or landlord-owned sets serving several tenants, where one fault darkens a row of units.
Repairs
Generator faults we fix in Rosslyn
ATS and changeover problems
The set runs but the building stays dark, or the load never returns to the mains.
AVR and voltage faults: Voltage problems
Low, high or swinging voltage from the AVR, exciter or rotating diodes.
Fuel and injector faults: Fuel system repairs
Contaminated diesel, blocked filters, air in the lines, lift pumps and injectors.
Overheating
Shutdowns from blocked radiators, failed fans, thermostats and coolant leaks.
Control panel errors: Control panel repairs
Alarms, lockouts and wiring faults on DSE, ComAp, SmartGen and other controllers.
Battery and charging faults: Battery not charging
Chargers, charge alternators and batteries that cannot crank the set when the mains fails.
Local conditions
Plant rooms and production lines in Rosslyn
Rosslyn grew around its vehicle plants. BMW has built cars here from 1968, Nissan agreed in January 2026 to sell its Rosslyn plant to Chery South Africa, subject to regulatory approval, and in the Automotive Supplier Park component makers supply the plants. A standby set here is part of a production chain: when a supplier’s line stops, so do its deliveries.
A plant repair starts at the gatehouse: induction, a permit to work, an escort to the plant room. We lock out the set with the site electrician, trace the fault, and test the transfer under real load when production can spare the minutes.
- Inductions and permits arranged with site security
- Fault traced with the set isolated and locked out
- Load transfer tested when production allows
Response
On site in Rosslyn in 1–2 hours
Technicians on site in 1–2 hours, 24/7. Rosslyn lies on the north-western side of Pretoria, with its own train station, and the R566 links it with Pretoria North. Tell us which gate to use, the contractor-access rules and whether a bakkie can reach the set.
While you wait, check only the fuel gauge, main breaker, emergency stop and controller screen, and stop after two start attempts; switchgear and fuel lines stay closed. WhatsApp a photo of the nameplate, controller and hour meter; emergency generator repair explains a night-shift callout.
Every make
Generator makes we repair in Rosslyn
We Service & Repair All Generator Brands. In Rosslyn’s plant rooms that usually means large diesel sets on Cummins, Perkins, MTU or Volvo Penta engines, with Stamford or Leroy-Somer alternators and Deep Sea Electronics or ComAp controllers. Workshops and smaller units run silent diesels from Kipor, Bundu Power, Pramac and others. Our brand pages cover each one.
Prevention
Why a Rosslyn set breaks down twice
A set that fails twice usually kept its cause: a new AVR on a set whose load still crowds one phase, fresh filters fed from the same bulk tank with water in it, or a cleaned radiator still drawing air from a dusty yard. The repair report lists what we saw beyond the fault we fixed.
Planned servicing breaks that cycle. Our Rosslyn generator service and maintenance page explains what a plant-room or factory service includes, how daytime outages bring the next one forward, and our plans for plant managers. Generator repairs shows how we diagnose a fault; we also work in Akasia, Soshanguve and Ga-Rankuwa and Mabopane, and across the Pretoria area hub.

FAQ
Frequently asked questions
Can you repair our Rosslyn plant’s generator without stopping production?
Usually. Diagnosis and most repairs are done with the plant on mains and the set isolated; only the loaded test and the transfer back need production time, and we book those between shifts. We work 24/7.
Our Supplier Park line stopped because the generator never took the load. What failed?
Usually the changeover rather than the engine: a mains-sensing fault, a contactor or breaker that did not close, or a controller left out of automatic. A technician tests it with the set isolated; see changeover and ATS problems.
The voltage drops whenever our press or compressor starts. Is the generator too small?
Sometimes, but often the AVR is slow or the load sits on one phase. We measure starting current and each phase under the real load and say whether the set has margin; see the kVA sizing guide.
Do you work on the older sets in Klerksoord factory units?
Yes. An older set and its changeover panel are tested part by part, and the report says whether a repair makes sense or the money is better spent elsewhere; see repair or replace.
