After Sales & Maintenance

Generator maintenance programs

From scheduled care to emergency call-outs, our generator maintenance covers the whole system, not just the engine.

Annual maintenance contract

Yearly care and upkeep of your generator set under one plan.

Scheduled maintenance

Inspection and servicing at set intervals to prevent breakdowns.

Emergency inspection

Technicians on call to inspect and fix faults when they occur.

Engine oil change

Oil and filter replacement with genuine parts.

Control system & ATS upgrade

Improve or retrofit control panels, MDB and ATS.

Training & consulting

Operation training and technical advice for your team.

Running at low load? Test it properly.

Generator sets that run below 30–40% load, or idle for long periods such as weekly engine tests, burn fuel incompletely. Carbon builds up on the piston crown and sticky residue collects around the intake and exhaust valves.

The result is reduced engine efficiency and white smoke. Our load testing service brings the engine back to working temperature under proper load.
