3512E TIER 4 FINAL ENGINE MEETS CRITICAL LAND DRILLING REQUIREMENTS
A key part of developing our solution to meet U.S. EPA Tier 4 Final emissions standards was meeting with land drilling customers to make sure we understood your requirements. Take a closer look at the Cat® 3512E Tier 4 Final Land Electric-Drive Drilling Engine, and you’ll see that it addresses the critical factors you told us matter most.
WHAT YOU ASKED FOR |
WHAT THE 3512E DELIVERS |
No secondary fluid requirement |
NOx reduction without Diesel Exhaust Fluid (DEF) or urea Our Exhaust Gas Recirculation (EGR) solution eliminates the need for a secondary fluid — thereby eliminating the costs and headaches associated with storing, shipping, stocking and handling DEF on dirty, remote, extreme-temperature sites. |
Reduced operating costs |
Lower fuel consumption to decrease overall costs Though many people think EGR technology increases fuel consumption, we’ve proven otherwise. Comparing identical drilling load profiles, our Tier 4 Final model consumes up to 4% less diesel than the Tier 2 model. No need for secondary fluid reduces operating costs even further. |
Transient performance maintained |
+/-1.5 Hz fluctuation with more than 50% block load With all the added technology required to meet emissions standards, you might expect to lose some performance. Not with the 3512E. Our Tier 4 Final engine beats all expectations, performing the same as the Tier 2 model — even better in some load conditions. |
Similar footprint for ease of packaging |
Minimal changes to existing master skid design We know space is tight on drilling rigs. By building our emissions-reduction solution into the engine itself — with no DEF storage requirements — we’ve kept the footprint of our Tier 4 Final engine about the same as that of the Tier 2 model. |
Same or better service intervals |
Extended top-end overhaul from 11,000 to 16,500 hours You want to spend more time working and less time servicing. We agree. Our Tier 4 Final engine maintains or improves on service intervals with the same maintenance procedures and scheduling as the Tier 2 model — and requires just one top-end overhaul at 16,500 hours instead of two top-end overhauls at 11,000 and 22,000 hours. |
