This column cooling coil is designed to fit in 6″ Tri-Clamp material columns and allows the user to either chill or heat the column up from the inside which increased the surface area beyond a standard dewaxing jacket and reduces the need for dry ice. This cooling coil is made out of 304 stainless steel and has a 3/8″ diameter coil spiraling from (3) 1/4″ FNPT ports on the top with 2 of them connecting to the coil and one of the connecting to the dip tube
