OKC Series

Description

These coolers use a combination of high performance cooling elements and high capacity, compact AC Electric powered fans to give long trouble free operation in hydraulic applications.

The compact design allows the coolers to fit most equipment and provide the highest cooling performance in heat dissipation while minimizing space required.
