Abstract
An enamel flow coating process and apparatus is arranged as a four arm Ferris wheel like apparatus which is mounted over a bathtub like tank which holds enamel slip. Coils of steel tubing formed into heat exchangers are mounted to the arms of the wheel to rotate and to pivot. The wheel is rotated between four stations. In the first station, a coil is loaded onto the wheel. In a second station the coil is pivoted into the tank of enamel slip, where it is coated, and withdrawn by operation of a pivoting bracket. The coated coils are rotated through third and fourth stations where the coating solidifies, and the coated heat exchanger is removed, and replaced with an uncoated one in the first station. After leaving the wheel, the heat exchanger is fired and installed in a water storage tank.
