The Cat® C13D IPU configuration not only provides the flexibility and options found on a standard industrial engine, but also comes fitted with an integrated cooling system, an on-engine fuel filtration module, as well as full wire harnessing leading to an engine-mounted ECM. Meeting UN ECE R96 Stage IIIA, Brazil Mar-1, and other equivalent emission standards, the IPU allows for easier and faster installation, allowing the customer to spend more time doing the work that matters.
