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.
