01
Sizing & installation interfaces
Share starting currents, phase requirements and load sequence. Ventilation, exhaust, access, noise and fuel arrangements require a site assessment.

BM CONTRACTORSENGINEERING · TANZANIAGenerators, ATS & power integration
Standby power. Considered as a whole.
BM handles generator system enquiries, installation integration and service-parts sourcing requirements. Generator capacity, transfer equipment and the building installation must be considered together.

A CONSIDERED SCOPE
Generation, transfer and distribution.
Who is it for?
Businesses and institutions needing standby power, with essential loads, operating hours and a suitable installation location clearly identified.
Your quotation should set out the assessed equipment, installation, documentation and agreed delivery terms.
02
ATS, service & parts
Discuss manual/automatic transfer, protection and integration with solar or UPS. For service parts, provide generator, engine and alternator identifiers; compatibility is verified before quotation.
EQUIPMENT & APPROACH
Selection follows the requirement.
Generator set and controller; manual or automatic transfer equipment; suitable protection and cabling; starting battery; model-specific filters, belts and service consumables.
Explore equipment & specification guidance ↗Assessment, installation & handover
Review running and starting loads, phase and supply details, access, ventilation, exhaust routing and fuel arrangements. Agree the transfer design and installation responsibilities, then perform documented functional checks within the approved scope.
Maintenance & ongoing care
Follow the specific manufacturer service schedule and operating-hour record. Log faults, fluid checks and battery condition. Provide the engine and alternator model/serial details when requesting parts; appearance alone is insufficient.
THE TECHNICAL BRIEF
The genset is one part of the power system.
BM generator enquiries cover assessed supply, installation, changeover, control and service requirements. Confirm the exact genset identity before specifying parts.
| Option / application | What to assess |
|---|---|
| kW / kVA and duty | Distinguish active power from apparent power, and standby duty from prime duty. Size for phase balance, motor starting, ambient conditions and the intended operating schedule. |
| ATS / AMF | ATS switches the power path; AMF control monitors supply and manages generator start/stop. The controller, switching assembly and protection must work together. |
| Controls and service parts | Record genset, engine, alternator and controller model/serial numbers. Filters, belts, sensors and chargers require exact compatibility, not just an engine-brand match. |
Site integration
Assessment includes access and base, ventilation, exhaust route, noise-sensitive areas, fuel arrangements, cable/protection and earthing. A controller change needs wiring, sensing and protection review; factory settings should not be assumed suitable.
Commissioning and care
Agree mains-failure/return tests, transfer and retransfer behaviour, staged load testing, alarms and operator handover. Service intervals follow the exact engine/genset manual, operating hours and conditions; no universal service interval is promised.
Does a DSE controller include the automatic transfer switch?
No. A controller such as the DSE7320 MKII manages AMF functions; appropriately rated switching equipment and a correctly designed installation are still required.
Equipment references & manufacturer documentation
These references help compare systems. They do not establish BM stock, dealership, partnership or model availability. Confirm equipment, compatibility and supply terms in the quotation.

BEFORE YOU DECIDE
Questions worth asking.
Can you select a generator from my electricity bill?
A bill gives consumption context, not the complete peak or starting demand. An equipment schedule and load assessment are needed.
Are service parts interchangeable?
Do not assume so. Confirm engine model, serial number and the required part reference before ordering; availability and suitability require a quotation.
