Services included with every sale

Site survey & load analysis

We perform a full electrical load assessment to correctly size the generator and to plan for starting currents and essential circuits.

Installation & commissioning

Certified electricians and technicians handle mechanical installation, wiring, ATS (automatic transfer switch) integration and commissioning tests.

Load testing

On-site load testing with reporting and certification to verify performance under expected loads.

Planned maintenance

Service contracts, spare parts stocking and emergency callout options keep downtime to a minimum.

Industrial generator buying guide

1. Understand your load — identify critical circuits, motor starting loads and peak demand.
2. Choose fuel type & configuration — diesel is common for industrial sites; choose canopy vs containerised based on site constraints.
3. Consider redundancy — parallel multiple sets for N+1 resiliency when required.
4. Plan for installation — bunding, acoustic treatment, fuel tanks and access for refuelling must be included in the plan.
5. Service & support — confirm local support, spare parts and service-level agreements.
