• Commercial Buildings: Powers HVAC systems, elevadores, iluminação, and IT infrastructure in office buildings, shopping centers, e hotéis.
• 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 soluções.
• Centros de dados: Provides Tier III/IV backup power for server rooms and network operations centers. Explore our data center generator options for mission-critical facilities.
• Canteiros de obras: Powers heavy equipment, iluminação, and temporary facilities on remote job sites.
• Mining Operations: Supplies continuous power for extraction equipment, ventilação, and camp facilities in remote mining locations.

Fuel Consumption Details

Understanding fuel consumption is critical for calculating operating costs. O 50 kW diesel generator consumption varies significantly with load:

Importante: Running a generator below 30% load for extended periods causes “empilhamento molhado” — unburned fuel accumulates in the exhaust, reducing engine life. Always size your generator so the typical load is between 50-80% de capacidade nominal.

Price Breakdown: What Affects the Cost?

The price of a 50 kW diesel generator ranges from $8,000 para $15,000 (FOB), depending on several factors:

1. Marca do motor

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% prêmio
• Perkins: British engineering, widely used in Europe and Middle East
• PESSOA: German engineering, best for high-performance applications, 15-20% prêmio
• Weichai / Yuchai: Chinese engine brands, competitive pricing, growing global acceptance

2. Tipo de gabinete

• Conjunto aberto: Menor custo, requires dedicated generator room
• gerador silencioso: +15-25% custo, reduces noise to 65 dB(UM)
• containerized generator: +25-35% custo, weatherproof, móvel, quick deployment

3. Alternator Brand

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

4. Controller

• Mar Profundo (DSE): Padrão da indústria, confiável, easy to program
• ComAp: Advanced features, monitoramento remoto, multi-unit sync
• SmartGen: Cost-effective Chinese brand, growing market share

How to Choose the Right 50 Gerador de kW

Etapa 1: Determine Your Power Requirement

List all the equipment you need to power simultaneously. Adicionar 20% headroom for motor starting surges and future expansion. UM 50 kW generator is typically suitable for loads between 25-40 kW.

Etapa 2: Choose Standby vs. Poder Principal

• Espera: Emergency backup only, runs less than 200 horas/ano. The generator can output 100% potência nominal.
• Melhor: Operação contínua, corre 8,000+ horas/ano. De-rate by 10% (output is 90% de potência nominal).

Etapa 3: Select the Enclosure

If noise is a concern (residential area, hospital, office building), choose a gerador silencioso. If you need mobility or quick deployment, choose a containerized generator.

Etapa 4: Verifique o fornecimento de combustível

UM 50 kW diesel generator at 75% load consumes approximately 9.8 L/h. For 24-hour operation, you need a base tank of at least 235 litros. Plan for daily fuel delivery or install an external day tank.

Requisitos de instalação

Ventilação

The generator room must provide adequate airflow for combustion and cooling. UM 50 kW unit requires approximately 312 m³/h 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 kg 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 Chave de transferência automática (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.

Cronograma de Manutenção

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