Description of Cummins KTA50 G3 Generator Engine

• Dual Frequency to Meet Diverse Energy Needs
• Cummins KTA50-G3 Diesel Engine is both 50and 60 Hz capable, with a wide voltage rangefor Continuous, Prime or Standby applications in commercial, residential, industrial, utilities, and more. It is widely acknowledged as the most robust and cost effective diesel engine in its power range for the generator set market.
• An Engine That Works Harder, Longer
• Cummins KTA50 G3 generator is recognized forperformance, reliability and durability worldwide. With its very high derating threshold fortemperatures, altitudes and humidity,  KTA50-G3 Industrial Engine ranks among the top performers inthe harshest operating environments.
• A Unit That Stays Cool, In The Hottest Places on Earth
• The cooling system is engineered to meet Limiting Ambient Temperature (LAT) up to 50°C at Continuous rating. Designed with vertical hot air discharge, the KTA50 G3 series engine is suitable for multiple set installations.

Features

• Integrated Design: Products are supplied complete with cooling package and air cleaner kit for a complete powerpackage. Each component has been specifically developed and rigorously tested for G-Drive products, ensuring highperformance, durability and reliability.
• Aftercooler: Large capacity integral aftercoolers are supplied with cooling water separate from the engine jacket. This provides cooler, denser intake air for more complete combustion and reduced engine stresses for
  longer life and low exhaust emissions.
• Cooling System: Gear driven centrifugal water pump, two loop system must be employed, namely the engine jacket is cooled by one radiator or heat exchanger and the aftercoolers are cooled by a separate radiator or heat exchanger.
• Pistons: Pistons are dual Ni-resist, aluminium alloy, cam ground and barrel shaped to compensate for thermal expansion assures precise fit at operating temperatures. Grooved skirt finish provides superior lubrication. Oil cooled for rapid heat dissipation.
