Critical loads
ICU, operating theatres, medical gases, lifts, pumps and IT can have different continuity requirements.
UPS coordination
No-break loads require battery-backed ride-through while the generator starts.
Testing
Automatic start and transfer should be tested regularly under realistic conditions.
What a serious buyer should verify
Common specification mistakes
Common errors include quoting only a headline kVA, ignoring starting current, omitting ATS or protection scope, assuming a silent canopy solves ventilation, and failing to define who is responsible for exhaust, fuel, foundation, cabling and earthing.
For a critical facility, the handover should include an operating sequence, alarm checks and representative loaded testing. The generator is only one component of the backup-power system.
Load behavior in a hospital or healthcare facility
A hospital or healthcare facility rarely behaves like one steady resistive load. Motors, lifts, pumps, compressors, cooling equipment, UPS systems and process loads can start at different times and create short-duration step loads that matter more than the average kW figure.
The useful design question is which loads must remain alive during a grid outage and in what order they are allowed to start. Separating critical from noncritical loads can reduce generator size, improve fuel use and make the emergency sequence easier to control.
Research methodology and freshness
PS Power buying guides 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. Updated 30 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

| 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. |
