Immersion chiller

[jun77]

Hi Im thinking of buying large Herms coil immersion chiller for cold break of 90-100 gallon wort
from 100 degree celsius to 20 degree celsius with Duda 90 plate chiller within 30-60 min. But I dont know how much large immersion chiller should I choose (exp; length and width) Is there someone who know appropriate sizes of immersion chiller for cold break of 100 gallon wort ?

Doesn't the size depend on the vessel it is going into?

A little narrower than the diameter of the kettle and as high as the depth of the liquid you are trying to cool.
