Abstract
A fluid heater for heating high solids fluids having a solids content approximately 50% or higher, which fluids are applied to a substrate by a coating process, includes a cylindrical body of thermally conductive material having a helical channel formed on the outer periphery thereof and including a section member dividing the channel into a pair of side-by-side passages, each having a cross-sectional area of about 0.119 square inches and a length of about 80 inches. A common input plenum identical in size to the cross-sectional area of the channel communicates with one end of each of the passages and the other end of the passages are connected to a common output plenum. An electric heating element is located in said body along the central axis thereof and is sized to produce a watt density on the surface of said passages in the range of 7.5 to 8.0 watts per square inch whereby the high solids fluids are heated for ease in application with a minimum loss of fluid pressure upon passing through the heater.
