The Cat® C7.1 marine diesel generator set has 50 Hertz three-phase ratings of 100, 118 and 150 ekW with heat exchanger cooling and meets U.S. emissions regulations. EPA Tier 3 commercial, IMO II and EU CC2. It also has three-phase 60 Hertz power ratings of 118, 150 and 175 ekW with heat exchanger cooling, complying with U.S. emissions regulations. EPA Tier 3 commercial, IMO II and EU CC2.

Why Choosing It

Common rail fuel system

 

One of the main advantages of the C7.1 generator set is the Common Rail fuel system, with variable multiple injection and a high compression ratio that ensure optimal fuel efficiency and very low smoke production.

 

Excellent fuel consumption, optimal combustion, reduced emissions

 

The injection pressure of the model is independent of load and speed. While all injection characteristics are optimized for each operating phase of the engine

 

The model provides for a reduction in NOx and soot emissions, where the amount of reduction depends on the actual operating conditions of the engine.

 

Control panel

 

Location interchangeable between 3 positions
