Separate critical loads
Operating theatres, ICU, medical gases, emergency lighting, lifts, pumps, IT and diagnostics can have different continuity needs.
Coordinate UPS and generator
Sensitive equipment may require UPS ride-through while the generator starts and stabilizes.
Test the whole system
Routine tests should verify automatic starting, transfer, return to mains, alarms, batteries and fuel readiness.
Buyer checklist
Verify the complete project scope
Confirm exact equipment model and rating, scope of supply, installation responsibility, commissioning, warranty, spare-parts path and after-sales support. For industrial power projects, the lowest initial price is not automatically the lowest lifecycle risk.
Advanced buyer notes
For meaningful comparison, normalize the exact technical specification, installation and commissioning scope, written warranty, spare-parts route and after-sales response. Search rankings, company names and import volume are useful discovery signals, but the project decision should be based on equivalent technical offers.
Research methodology and freshness
PS Group research pages separates company claims, public third-party data and general engineering guidance. Dataset-specific figures are labelled with their scope; competitor names are used for buyer comparison without implying affiliation; and technical values are treated as references until verified against the final project and manufacturer documentation. Last reviewed 21 September 2026.
Evidence worth requesting before purchase
Ask for the manufacturer data sheet, serial/model references, warranty terms, commissioning checklist and a clear list of inclusions and exclusions. For high-capacity or critical installations, request evidence of load testing and confirm the site engineering assumptions before delivery.
Brands commonly researched in Bangladesh
Industrial buyers frequently research Perkins, Cummins, Ricardo, Mitsubishi, Volvo Penta, Yanmar, Weichai, Yuchai, MTU, Baudouin, Doosan, Lovol. The practical comparison is not only brand versus brand: exact engine model, complete genset configuration, project duty and after-sales support determine whether a proposal fits the application.
Generator specification checklist
| Component | What should be written in the offer |
|---|---|
| Engine | Manufacturer and exact engine model. |
| Alternator | Manufacturer/model and insulation/protection class where specified. |
| Controller | Exact controller and required communications. |
| Rating | Prime and standby kVA/kW with applicable standard. |
| Enclosure | Open, silent canopy or containerized configuration. |
| Switching | ATS, motorized breaker or synchronizing scope. |
| Site works | Foundation, exhaust, fuel, cable, earthing and commissioning responsibility. |
Frequently asked questions
How quickly should backup start?
It depends on load classification and project requirements; some loads require no-break UPS support.
Should hospitals use redundant generators?
Critical facilities often evaluate N+1 or multiple-set architectures.
Why test under load?
It can reveal cooling, fuel and electrical-transfer issues before a real outage.
