What Applications Use a 100 Générateur kW?

UN 100 kW diesel generator is a versatile power solution that serves multiple industries and applications:

  • Usines de fabrication: Provides backup power for production lines, ensuring zero downtime during grid outages. A single 100 kW unit can support a mid-size factory with critical loads.
  • Bâtiments commerciaux: Powers HVAC systems, ascenseurs, éclairage, and IT infrastructure in office buildings, shopping centers, and hotels.
  • Healthcare Facilities: Serves as emergency backup for hospitals and clinics where power interruption is not an option. Must comply with NFPA 110 requirements for 10-second start. See our hospital generator solutions.
  • Centres de données: Provides Tier III/IV backup power for server rooms and network operations centers. Explore our data center generator options for mission-critical facilities.
  • Chantiers de construction: Powers heavy equipment, éclairage, and temporary facilities on remote job sites.
  • Mining Operations: Supplies continuous power for extraction equipment, ventilation, and camp facilities in remote mining locations.

Fuel Consumption Details

Understanding fuel consumption is critical for calculating operating costs. Le 100 kW diesel generator consumption varies significantly with load:

Niveau de chargeConsommation de carburant (L/heure)Coût quotidien (24h @ $1.2/L)
100% (Attendre)24$691
75% (Typique)19$547
50% (Low load)14$403

Important: Running a generator below 30% load for extended periods causes “empilement humide” — unburned fuel accumulates in the exhaust, reducing engine life. Always size your generator so the typical load is between 50-80% de capacité nominale.

Price Breakdown: What Affects the Cost?

The price of a 100 kW diesel generator ranges from $15,000 à $28,000 (FOB), depending on several factors:

1. Marque du moteur

The engine is 60-70% of the total cost. Premium brands cost more but offer better reliability and resale value:

  • Cummins: Most popular globally, excellent parts availability, 5-10% prime
  • Perkins: British engineering, widely used in Europe and Middle East
  • PERSONNE: German engineering, best for high-performance applications, 15-20% prime
  • Weichai / Yuchai: Chinese engine brands, competitive pricing, growing global acceptance

2. Type de boîtier

3. Alternator Brand

  • Stamford / Leroy Somer: Premium, best for non-linear loads
  • Marathon / Mecc Alte: Good quality, competitive pricing
  • Chinese brands (Non, etc.): Budget-friendly, adequate for standard applications

4. Controller

  • Mer profonde (DSE): Norme industrielle, fiable, easy to program
  • ComAp: Advanced features, surveillance à distance, multi-unit sync
  • SmartGen: Cost-effective Chinese brand, growing market share

How to Choose the Right 100 Générateur kW

Étape 1: Determine Your Power Requirement

List all the equipment you need to power simultaneously. Ajouter 20% headroom for motor starting surges and future expansion. UN 100 kW generator is typically suitable for loads between 50-80 kW.

Étape 2: Choose Standby vs. Puissance principale

  • Attendre: Sauvegarde d'urgence uniquement, runs less than 200 heures/an. The generator can output 100% puissance nominale.
  • Prime: Fonctionnement continu, court 8,000+ heures/an. De-rate by 10% (output is 90% de puissance nominale).

Étape 3: Select the Enclosure

If noise is a concern (residential area, hôpital, immeuble de bureaux), choose a générateur silencieux. If you need mobility or quick deployment, choose a containerized generator.

Étape 4: Vérifier l'approvisionnement en carburant

UN 100 kW diesel generator at 75% load consumes approximately 19 L/heure. For 24-hour operation, you need a base tank of at least 456 litres. Plan for daily fuel delivery or install an external day tank.

Exigences d'installation

Ventilation

The generator room must provide adequate airflow for combustion and cooling. UN 100 kW unit requires approximately 625 m³/heure of ventilation air. Install intake louvers on the low wall and exhaust louvers on the high wall opposite the radiator.

Foundation

The foundation must support the static weight of 1,800 kilos plus dynamic loads during operation. A reinforced concrete pad of at least 200mm thickness is recommended, with anti-vibration mounts between the generator and the pad.

Electrical Connection

Use an Commutateur de transfert automatique (ATS) to switch between grid and generator power. The ATS should be rated for the full load current and include time-delay features to prevent unnecessary starts during momentary outages.

Calendrier d'entretien

Regular maintenance extends engine life and ensures reliable starting when you need it most:

IntervalleTâche
Tous les joursVérifier le niveau d'huile, niveau de liquide de refroidissement, niveau de carburant, tension de la batterie
HebdomadaireRun under load for 30 minutes, vérifier les fuites
MensuelClean air filter, check belt tension, test safety shutdowns
Chaque 250 heuresChange oil and oil filter, check valve clearance
Chaque 500 heuresReplace fuel filter, clean fuel tank, check injector nozzles
Chaque 1,000 heuresAdjust valve clearance, test alternator insulation, check control system
Chaque 2,000 heuresOverhaul cylinder head, replace coolant, test alternator winding resistance

For a detailed checklist, see our diesel generator maintenance schedule guide.
