Behind every Cat machine or generator is a powerful, reliable engine. For industrial purposes, we sell both gas and diesel engines in a range of sizes and specific applications. For tightly regulated industries, we offer U.S. EPA Tier IV Final engines that will position you to easily achieve compliance with all future regulatory standards.

For lesser and non-regulated industries, our engines can still be counted on to delivery exceptional performance and fuel efficiency. The result of more than $500 million in research, the ACERT line of products is our most sophisticated engine yet, featuring an advanced air cooling system and a precision injection technology. To learn more or for assistance choosing the right engine for your needs, contact a Walker power expert today.
