Where Diesel Generators Make Sense

Diesel generators provide immediate, controllable power with strong motor‑starting capability. They are suited to sites where outages disrupt operations, where grid supply is weak, or where prime power is required for construction or remote operations.

Typical scenarios

  1. Homes, clinics, and schools seeking reliable backup during outages.
  2. Shops and SMEs with refrigeration or air‑conditioning loads.
  3. Industrial sites with compressors, pumps, and process motors.
  4. Construction projects and events needing temporary power.

Advantages

  1. High power density and proven durability.
  2. Better fuel economy than gasoline at comparable output.
  3. Readily available service networks and parts.
  4. Can be paralleled for redundancy or growth.

Sizing & Selection

Correct sizing protects your investment and ensures quiet, efficient operation. Our engineers follow a transparent approach:
  1. Load audit: List equipment, running watts, and startup surges; identify single‑phase/three‑phase split.
  2. Duty cycle: Backup vs prime power, expected daily hours, ambient temperatures.
  3. kVA calculation: kVA ≈ kW ÷ Power Factor. Many mixed loads sit around PF 0.8; motors may be lower.
  4. Motor starts: Size for highest simultaneous start (2–6× running current); soft starters/VFDs reduce surge.
  5. Voltage & phases: Single‑phase 230V vs three‑phase 400V; ensure balanced phases.
  6. Altitude & heat: Apply derating for high temperatures and elevation to protect engine life.

Worked example — Home/Office

Essential loads: fans, lights, router, fridge, 1–2 inverter ACs. With documented surges and a realistic duty cycle, many homes fit well around 10–20 kVA—exact rating depends on simultaneity and phase split.

Worked example — Clinic/Workshop

Multiple ACs, medical/lab equipment, compressors or pumps. Systems often fall between 20–50 kVA; for heavier tools or extended runtime, consider 50–100 kVA with room to parallel later.

Popular Ratings & Use‑Cases

No Rating Typical Uses Notes
1 Perkins 20 kVA Homes, small clinics/shops Often single‑phase; strong starts for essential appliances.
2 Perkins 30 kVA Homes with multiple ACs; small offices Balanced output for mixed loads; quiet with a good canopy.
3 Perkins 50 kVA Workshops, mid‑size retail, labs Three‑phase; comfortable motor starting; ATS preferred.
4 Perkins 100 kVA Clinics, campuses, construction Parallel‑ready options for redundancy and growth.

Searching for “10kVA diesel generator price Pakistan” or “100kVA diesel generator price Pakistan”? Final pricing depends on brand, alternator class, canopy/acoustic level, controls, and installation scope. Ask for an itemized quote.

Engine & Alternator Brands

We supply, integrate, and service a range of engines and alternators, including Perkins, Cummins, and FG Wilson—as well as compatible alternators and controllers—based on your budget and uptime targets.

Perkins

Known for smooth operation, parts availability, and broad power range. Searchers for “Perkins diesel generator price Pakistan” should compare model, alternator, and canopy spec—not just kVA.

Cummins

Robust engines with strong service networks. Compare controller features, AVR quality, and sound attenuation.

FG Wilson

Integrated sets with refined acoustics. Evaluate options like two‑wire start, remote monitoring, and rated sound levels.
Brand badges don’t guarantee the same performance across all trims. Always compare alternator class, controller options, sound attenuation, and the installation details that protect longevity.

Silent Canopies & ATS Panels

Silent diesel generators

Acoustic canopies lower noise with lined panels, tuned air paths, and anti‑vibration mounts. When you research “silent diesel generator price Pakistan,” check the rated dB(A) at 7 m, ventilation path, and service access to avoid maintenance headaches.

ATS & synchronization

An ATS panel transfers loads automatically during outages and returns to grid when power stabilizes. We offer AMF/ATS controls, two‑wire start, and options for generator‑to‑generator or generator‑to‑grid synchronization, plus load‑sharing if you plan to parallel sets.

Looking up “ATS panel for generator price Pakistan”? Price depends on rating (A), breakers/contactors, controller brand, and enclosure grade.

Fuel Consumption & Operating Cost

Fuel use depends on load, engine displacement, speed (1500 vs 3000 RPM), altitude, and maintenance. A simplified view:
  1. Engines are most efficient around 60–80% load; idling or very light load wastes fuel and can cause wet‑stacking.
  2. Specific fuel consumption (SFC) is often expressed as liters/kWh. Comparing SFC across models helps estimate per‑hour costs for your loads.
  3. Clean filters, correct oil, and timely servicing protect efficiency and engine life.
For “diesel generator fuel consumption per hour Pakistan,” we provide site‑specific estimates after sizing—far more reliable than generic tables.

Supply, Installation & Commissioning

Site & plinth

We survey airflow, exhaust path, rain exposure, and cable runs. Plinths are sized for weight and vibration; canopies get service clearances for filters and radiators.

Electrical & safety

Correct cable sizing for voltage drop, earthing and bonding, labelled isolators, and compliant changeover schemes to avoid backfeed.
  1. Commissioning includes oil/coolant checks, load tests, controller setup, and operator training.
  2. Handover pack: single‑line diagram, datasheets, warranty cards, and service schedule.
