Cat 3500 Tier 4 Land Well Service Engine

Posted on May 6, 2013

Caterpillar Global Petroleum has announced the launch of the Cat 3512E (HD) land well service engine. The new EPA Tier 4 final 3512E engine is offered with air-to-air aftercooling (ATAAC) and separate circuit after cooler (SCAC) configurations in two power ratings: 1678 bkW (2250 bhp) at 1800 rpm and 1864 bkW (2500 bhp) at 1800 rpm. The engine will be available for customers to order in 2014, Cat said

Manufactured in Lafayette, Ind., Cat said the 3512E (HD) meets Tier 4 final using a NOx Reduction System (NRS) and Diesel Oxidation Catalyst (DOC), as well as aftertreatment and various engine attachments. Customers will also have the option to purchase the engine with the air cleaners, aftertreatment, and exhaust system installed from the factory, Cat said.

“This greatly simplifies the Tier 4 engine integration for OEMs since Caterpillar has already invested in the design and validation of these engine mounted exhaust systems,” Brian DeCaires, Caterpillar Global Petroleum project engineer said.

The engine will be available with a single ADEM A4 engine control module, Product Link for engine monitoring, optional engine mounted transmission cooler, and optional air shut-off valve.

Caterpillar said that compared to the 3512C (HD) Tier 2 engine, there is up to a 5% improvement in fuel efficiency and increased ambient and altitude capability.

Caterpillar is positioning the new engine as part of a package for well stimulation trailers as one example, noting that the 3512E (HD) can be matched with a Caterpillar CX48 or TH55 transmission, and a newly introduced Caterpillar well stimulation pump.
