3512E DGB Tier 4 Final

Land Well Service 3512E Dynamic Gas Blending dual fuel Engine

The new land well service 3512E Dynamic Gas Blending™ dual fuel engine will be certified to U.S. EPA Tier 4 Final emissions standard while offering the highest natural gas substitution in its class. The 3512E DGB will include factory solutions that emit approximately the same or less greenhouse gas (GHG) emissions as a comparable 3512E Tier 4 Final diesel engine. Additionally, the dual fuel performance of the new 3512E DGB has significantly increased compared to similar engines in its class with the ability to achieve 85% diesel displacement, further allowing for lower operating costs.
