I felt the lone review was unjustifiably low so I felt I should clear a few things up. I have used 1, 2, and 4 line cool plates for years and here are my opinions._x000D__x000D_I would recommend using SS coils for 1-2 tap boxes and cold plates for anything more than that. This is strictly based on cost and cooler space. You will not have a problem cooling your beer with these if properly used. _x000D__x000D_1. Set this 2-3" from the bottom of the cooler to allow water and ice to envelope the plate._x000D_2. Do not keep draining the water out of the cooler. The more ice/water surface area contact there is the better it will cool. _x000D_3. You will have to play with your gas regulation to get your perfect pour. I usually end up around 18psi with a warm keg. Sitting in the sun, I can end up around 23-28psi. You'll have to do the same with a SS coil.
