Is Derale Tube-Fin Power Sterring Cooler Made with Copper

Question:

Lookin for cooler that has stainless steel tubing. Is this true with the derale 13212. All the specs never mention stainless tube. I do want this size of cooler but must have stainless steel tubing for my liquid I use to not cause me erosion problems. Cant use copper tubing. Thanks

These particular Derale Tube-Fin Coolers, part # D13309 and part # D13212, are copper tube with aluminum fin construction. Most of the coolers available will use copper and aluminum. Copper is used because it has excellent heat transfer abilities so it can transfer heat easily to aluminum which has excellent heat dissipation properties. Stainless does not transfer or dissipate heat as well.

Derale does offer some all aluminum coolers where both the tubes and fins are made of aluminum for those fluids that react with copper. If you have a range of acceptable sizes, I should be able to track down something that is all aluminum in a size that may work.
