Technology
Air Cooled, Copper Tube / Aluminum Fin
Mobile Air Cooled Copper Tube/Aluminum Fin Core
The DH Series is a low cost, high performance mobile core that is an excellent choice for radiator face mount fuel or transmission cooling. This series features moderate flows, high heat removal and an optional internal pressure bypass for cold start-up protection. Material options are also available including steel tanks and steel fins for rugged off-highway applications. Aggressive turbulators allow for optimal heat rejection at lower flow rates.
Engineered for hydraulic circuits up to 70 HP and oil flows up to 150 GPM in mobile systems.
Consult catalog for additional sizes and technical information.

Can DH Series cool a 150 HP diesel-powered hydraulic system?
Yes, the DH Series is suitable for diesel-powered hydraulic systems. But it depends on the heat you need to reject. DH is rated for up to ~70 HP heat removal and up to 150 GPM oil flow. If your calculated heat load is ≤ ~70 HP, DH can be a fit; if it exceeds ~70 HP, select a higher-capacity series via XSelector® or contact Application Engineering.
When should I use the internal pressure bypass?
Recommended for cold-start protection and variable-duty mobile systems.
What are the available material options?
Aluminum or steel fins and tanks for high-vibration or corrosive environments.
Can I use DH for transmission and fuel cooling?
Yes, the DH Series is optimized for radiator face mount and auxiliary cooling applications.
