Caterpillar has announced two new high-efficiency diesel industrial power units (IPUs) designed to enable OEMs to minimize engineering and assembly costs.
Created for construction, material-handling, and other off-highway applications in the 74 to 134 horsepower power range, the new Cat C2.8 and Cat 3.6 industrial power units are equipped with factory-installed ECM sensors, radiators, cooling packs, filtration, control systems and aftertreatment hardware.
Both IPUs meet the emissions standards of Stage V, Tier 4 Final, China Non-road IV, Korea Stage V and Japan 2014. With the addition of these power solutions, Caterpillar currently offers industrial power units from 48 to 950 horsepower addressing the emissions standards of higher regulated markets.
“OEMs with restricted engineering resources can shorten their design and assembly timelines with Cat IPUs,” said Steve Ferguson, Senior Vice President of Caterpillar Industrial Power Systems.
“These new drop-in packages offer design flexibility, power density, emissions compliance and field-proven durability in an integrated package that can help off-highway manufacturers accelerate their speed to market.”
Industrial power unit design
The flexible and innovative designs of the new Cat C2.8 and Cat 3.6 IPUs offer numerous features to meet the demands of off-highway equipment owners.
The industrial power units feature a common rail direct-injection design with a turbocharged C2.8 or turbocharged aftercooled C3.6 air system.
The ECM and aftertreatment hardware are mounted on the IPU and, along with the fuel filter, are validated to perform in harsh work environments. As well, Cat has developed a new wiring harness to allow for a simple hookup to machine wiring. For fast installation, an optional engine control panel for engine monitoring and speed control is also available.
To reduce downtime for regeneration, each industrial power unit is equipped with an on-engine diesel oxidation catalyst (DOC) and diesel particulate filter (DPF), while the Cat C3.6 also has selective catalytic reduction (SCR).
For operations in challenging work conditions, the IPUs are available with heavy-duty cooling packs that incorporate a pusher fan and erosion screen, as well as heavy-duty fuel filters with increased dirt-holding capacities.
Cat industrial power units enable customers to use renewable liquid fuels such as 100 per cent hydrotreated vegetable oil (HVO) and are equipped with Cat Digital Services, an integrated software suite and hardware solutions supplying the insight equipment owners need to make decisions on the fly, secure the health of their equipment and minimize non-productive time.
