Heat Sinks

An anodized (black) aluminum heat sink radiates heat better than a similar silver non-anodized heat sink. The emissivity of anodized aluminum is 0.85 while unfinished is only 0.05. Cooling can be increased by approximately 10 to 45%, depending on the application.

Purchase a heat sink at the same time as one of our control panel kits with pre-punched enclosure (or a standalone pre-punched enclosure) and we will tap the heat sink for you and include mounting bolts at no extra cost. Our heat sinks are made in the USA.
