Key Features of the 200 kW Cummins Natural Gas Generator
Rated Output: Approx. 200 kW (or 250 kVA at 0.8 PF), suitable for open‑type power plant configurations.
Fuel Type – Natural Gas: Offers cleaner fuel option compared to diesel, lower particulate emissions, potentially lower fuel cost.
Open‑Type Skid Design: Easier maintenance access, lower enclosure cost, suitable for engine rooms, industrial plants, or outdoor weather‐protected installations.
Engine Model / Technology: Based on Cummins gas‑generator platforms(e.g., QSJ8.9G)which respond quickly to load changes and meet performance demands.
High Efficiency & Reliability: Cummins natural gas generator sets are designed for high electrical efficiency, fuel variation tolerance, and robust operation.
Flexible Voltage / Frequency Options: Can be configured for 50 Hz or 60 Hz systems and a variety of voltages depending on region and customer requirements.
Comprehensive Control & Protection: Digital control system(e.g., Cummins PowerCommand®)with automatic start/stop, voltage/frequency regulation, fault alarms, and remote monitoring capability.
Environmental Compliance: Natural gas engine technology helps reduce emissions of NOₓ, CO₂ and particulates, making it suitable for stricter regulated sites.
Adaptable Installation: Open‑type design allows for custom enclosures, sound attenuation, or integration into larger power plants or microgrid systems.

Installation, Operation, and Maintenance Guidelines (IOM)
Installation Recommendations
Foundation & Location: Ensure the unit is placed on a sturdy, level foundation with adequate ventilation and exhaust space.
Gas Supply: Verify that the gas supply system (including pressure, quality, and temperature)strictly conforms to the engine manufacturer's specifications.
Accessibility: Dedicate sufficient space and access routes for future maintenance and service.
Startup and Commissioning
Initial Testing: For first-time operation, it is highly recommended to perform comprehensive no-load, half-load, and full-load tests.
System Checks: Thoroughly check and record the gas pressure, control system parameters, unit vibration and noise levels, and verify the correct function of all safety and protection devices.
Routine Maintenance
Periodic Inspection: Regularly inspect the gas delivery system, filters, lubricating oil, coolant levels, unit vibration and temperature readings, control panel status, and electrical cable connections.
Consumables: Follow the manufacturer's specified intervals for replacing consumables (e.g., filters, oil, spark plugs).
Spare Parts and Service
Critical Spares: We recommend maintaining an inventory of critical wear parts(e.g., filters, spark plugs, sensors, control modules)on-site.
Service Contract: Secure a long-term service agreement to ensure operational stability and minimized downtime over the unit's lifespan.
Safety and Environmental Compliance
Safety Measures: Ensure all gas piping meets regulatory standards, the exhaust system is safe, and the generator room is equipped with complete explosion-proof and fire-protection measures.
Compliance: Verify that noise control and emission levels fully comply with all applicable local regulations and codes.
