Cooling System
Durable and efficient
Aluminum Bar Plate Radiator
Cooling system uses a radiator built with rugged, highly efficient aluminum bar plate cores.
The aluminum bar plate construction aids durability and allows for higher heat transfer and superior
corrosion resistance.
Hydraulic Air to Oil Cooler
The new air to hydraulic oil cooler reduces hydraulic oil temperatures improving component life.
The core is built using the same rugged aluminum bar plate design as the jacket water cooler. It is
designed in-line with the water cores to minimize debris plugging in all applications.
Hydraulically Variable, Demand Fan
Provides engine cooling capability that is matched to the ambient conditions. In cooler conditions,
the fan turns at a slower speed, reducing power demands. This reduces fuel consumption in lower load
factor operations. Low speed fan operation also reduces both operator and spectator sound levels.
Attachments
• Ultra low speed option for cold weather applications
• Reversing cooling fan for heavy debris applications
