Plain Fins

As standard, our coils are manufactured from the highest quality plain aluminium fin stock to ensure that we get maximum secondary surface resulting in improved performance.

The plain aluminium fin stock is the most economical fin material we offer and tends to be used on around 50% of the coils we manufacture. It works well with heat transfer from the pipe to the extents of the fin block and has been used in refrigeration for well over a century.

We also offer a plain copper fin which gives the best heat transfer possible when used with our copper tubing. The plain copper fin option is usually selected for saline/coast environments as this lasts much better than plain or coated fin in these harsh conditions. We also offer a special electro-tin finish to our copper fin blocks - please click here for more info.
