ABSTRACT:
An atmospheric evaporator for reducing the water content of various chemical solutions, more particularly useful in the electroplating industry, wherein the evaporator includes a solution-secure molded tank in which a removable blower sleeve is mounted having a blower inlet duct and support strut members formed at the opposite end thereof to support a multiplicity of finned evaporator members over which the solution is sprayed. When a large-volume, low RPM blower is mounted to the inlet duct, a straight-line downdraft of both air and solution is created, allowing the air and evaporated water to exhaust through an up-facing outlet duct, thus defining a substantially "U" shaped duct arrangement from the inlet side to the exhaust side of the tank with the heavy chemical particles returning to the process tank from the bottom of the evaporator tank.
