Noise specification
Ask for dB(A), distance and load condition.
Cooling
A restrictive canopy can cause overheating if airflow is poor.
Outdoor use
Weather protection, drainage, foundation and exhaust still require engineering.
What a serious buyer should verify
How to use this guide
This guide provides a practical starting point for buyers and technical teams. Use the related guides to compare capacity, configuration, installation and lifecycle-support requirements before requesting a project-specific quotation.
Final decisions should use current quotations, manufacturer data and project-specific engineering rather than treating a general web page as the final specification.
Questions that improve a technical quotation
Ask the supplier to state assumptions instead of leaving them implicit: operating duty, environmental conditions, included accessories, site works, tests, delivery, commissioning, warranty and exclusions. If two offers cannot be normalized to the same scope, their prices are not directly comparable.
For a major purchase, keep the final technical schedule attached to the commercial order. This reduces ambiguity later when equipment is inspected, installed or handed over.
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.
