3516B with Dynamic Gas Blending

3516B Diesel Generator Set with Dynamic Gas Blending

Producing oil and gas is a complex task that requires specialized power generation equipment. Cat 3500 generator sets with Dynamic Gas Blending offer the lowest owning and operating cost by displacing diesel with low cost gas. They are specifically designed for the oilfield and combine decades of experience in diesel and gas engines with the latest electronics to ensure highest performance, optimum dual fuel operation, low emissions, and simplified operator interface.Cat generator sets are backed by the worldwide network of Cat dealers ready to support your operation with technical support, service, parts, and warranty.3516B generator set with dynamic gas blending kit. Ratings: 1600 ekW (2000 kVA) @ 50 Hz (1500 rpm).

Dynamic Gas Blending System

- Achieves up to 70% substitution while maintaining dieselperformance and safe engine operation- Closed loop control system enables maximumsubstitution over the widest load range in the industry- Maintains traditional diesel generator set power andtransient response performance- Accepts a wide range of gas quality and automaticallyadjusts to fuel quality changes, eliminating the need forfield calibration- EMCP 4.4 control panel features simplified rig integration,remote monitoring capabilities, and single point interfacefor the engine, generator, and Dynamic Gas Blendingfunctions- Leverages current hardware from G3516 product linewhile minimizing change to core diesel engine- Maintains existing diesel maintenance and overhaulintervals proven in oilfield applications

Engine Design
