What Applications Use a 50 Générateur kW?

UN 50 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 50 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 50 kW diesel generator consumption varies significantly with load:

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 50 kW diesel generator ranges from $8,000 à $15,000 (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

• Ensemble ouvert: Lowest cost, requires dedicated generator room
• générateur silencieux: +15-25% coût, reduces noise to 65 dB(UN)
• containerized generator: +25-35% coût, weatherproof, mobile, quick deployment

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 50 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 50 kW generator is typically suitable for loads between 25-40 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 50 kW diesel generator at 75% load consumes approximately 9.8 L/heure. For 24-hour operation, you need a base tank of at least 235 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 50 kW unit requires approximately 312 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 1,200 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:
