The heat sink is a precision thermal dissipator designed to extract heat from controller and power assemblies, reducing operating temperatures under sustained load. Finned geometry and optimized contact surfaces promote consistent thermal transfer when mounted to the designated heat interface points on Dualtron systems. Constructed from thermally conductive materials with corrosion-resistant finish, the unit bolts directly to factory mounting locations to improve cooling performance under load. Suitable for high-demand configurations within the Storm lineup.
