Malls and Commercial Buildings
Diesel generators for malls, offices and commercial buildings: sized for lifts, HVAC and lighting, soundproofing, synchronized systems and maintenance.

In shopping centres, office buildings and shops, lifts, escalators, lighting, checkouts and security systems must keep running during a power failure. A commercial building generator comes online when the mains fails and ensures people’s safety and business continuity.
What matters in commercial buildings?
- Critical loads: Fire pumps, emergency lighting, lifts and security systems must be supplied first.
- HVAC: Chillers create large motor starting loads; the generator must be sized for these starts.
- Noise and siting: In urban areas, a soundproof canopy and a correctly routed exhaust are essential to avoid disturbing the surroundings.
- Flexibility: Synchronized multi-generator systems run efficiently as the building load changes.

Frequently asked questions
Which loads should a generator supply in a commercial building?
At a minimum, the loads needed for the safety of people and property, such as emergency lighting, fire pumps, lifts, and security and CCTV systems. If business continuity is required, HVAC, refrigerated cabinets and checkout systems are also connected to the generator.
Why do shopping malls use more than one generator?
With several synchronized generators, some can be taken offline at low load to save fuel, and the building is never left completely without power during maintenance or a breakdown.
