Size of product condensers?

[Al Qaemist]

I have a stainless condenser, it's 1-1/2" over 1" and the jacketed section is 700mm long - mixing my units on measure there, but that's how it was cut up. Handles the strip on 3kw no problems, and when running slow for pot stilling gin, the product comes off cool 15oC with just a trickle of cooling water.

My tap water is very cold at this time of year, about 7oC, which may affect the outcome. I think I could easily chuck another few KW's at it without worrying it.
