SPP style etching of condensor coil

[kerberos]

If etching SPP packing allows the liquid to slide off more easily would a reflux condenser benefit from the same treatment?

I am thinking that if the condensate is on the coil for as little time as possible it would retain more energy when it returns to the column. Would this help the condensate be as high a temperature as possible on its return to the column?

It should also mean that less energy is taken from the coil due to the less time the condensate is in contact with the coil. This could also help in re-circulatory systems in keeping the water cooler for longer.

I am in the process of putting a couple of plans together for review here and this may or may not be part of them depending on feedback.

Any views on this will be gratefully received.

etching has the opposite effect, it helps wetting the SPP. You dont want that on your condenser .

So are we saying a polished coil is more effective?

If anyone has any links on etching and the science behind it i will be very grateful, thank you.

Etching a surface raises tiny "bumps" on its surface, making other things adhere to it better. Hence the term "wetting". It causes the fluid to stick to it better. SS isn't as good of a conductor as is copper, so it needs help.
