Wooden Air Cooled Water Chiller?
Does anyone have or know where to find plans for larger sized air cooled water chillers, such as those that used to be next to ice plants. The vertical towers had water dropping through wooden, slanted slats which created chaotic air flow through the water, removing heat and chilling the return water. Essentially speaking, I want to build a tower that can be used to chill large aquaria within outbuildings where fingerling trout are being raised.
In doing web searches all I am finding are the heavy duty industrial chillers that are high energy users, expensive, and would not work with solar driven small water pumps.
Thank you for any help, discussion or steer to websites.
