In an ordinary oil cooler, the oil flows straight through tubing without interruption. The oil nearest the wall of the tubing becomes “cool” and sluggish, while the oil near the center remains “hot” and thin. The cooler outer layer of oil serves as an insulation for the inner hotter oil and the thin, freely flowing oil at the center passes through the coil without the full advantage of heat exchange with the tubing. Simply stated, ordinary coolers are designed to get in their own way.

Perma-Cool® coolers incorporate the patented Turbulator™ fins to “mix” the hotter and cooler oil with oversize tubing to insure ample oil flow. The result is a design that takes full advantage of heat exchange with the coil and prevents stalling of the oil flow while providing more of a temperature drop. This difference is important and it’s only available from Perma-Cool®.
