i work with a stainless steel immersion chiller. it takes me about 1-1.5 hours to chill the liquid to 25 degrees (celsius). i have a pump that flows water from a stainless steel 30 liter pot with a lot of ice in to the chiller and the water goes back to the pot, when the water heats up i replace the pot with fresh cold water and ice (i do this action usually twice). do i have a better way to do it? and most important faster!? thank you.
