Open Frame or Silent Generator for Mining and Construction Sites

Why open frame wins on site

• Dust and heat: an open frame has direct airflow and is far easier to clean than a canopy.
• Maintenance: filters, injectors and belts are reachable in minutes, which matters when a machine is down.
• Price and weight: lower purchase cost and easier to move between sites.

Load fluctuation is the real challenge

• On a site, welders, concrete mixers and breakers start and stop all day.
• Size the set for the worst combination running at the same time, not the average load.
• For very unstable loads, consider a larger set running at partial load rather than a small set running at its limit.

Dust and fuel quality protection

• Fit an outer pre-filter or oil bath filter in very dusty conditions and clean it daily.
• Keep the fuel drum sealed and let it settle before refuelling; contaminated diesel damages the injection pump.
• Cover the set when it is not running, but never while it is running.

Transport and site placement

• Open frame sets from 3 kW to 9 kW are light enough for two people to move on the wheel kit.
• Place the set on level ground and never inside a closed room without ventilation.
• Exhaust must point away from working areas and from any intake air.
