Abstract:
1. A method of applying enamel slip to a heat exchanger coil comprising the steps of: mounting a heat exchanger coil on a rotatable shaft; while the heat exchanger coil is mounted to the rotatable shaft using an actuator to pivot the heat exchanger coil from a first position wherein the heat exchanger coil is not contained in an upwardly opening container of enamel slip, to a second position wherein the heat exchanger coil is substantially submerged in enamel slip contained in the upwardly opening container of the enamel slip to coat the heat exchanger coil with enamel slip; using the actuator to pivot the heat exchanger coil from the second position to a position where the heat exchanger coil is removed from the enamel slip and free to rotate on the rotatable shaft; after the heat exchanger coil is removed from the enamel slip initiating driving the rotatable shaft and causing the heat exchanger coil mounted thereto to rotate; and continuing to rotate the heat exchanger coil until the coating slip coating the heat exchanger coil is no longer liquid.
