Class Information
Number: 137/338
Name: Fluid handling > With heating or cooling of the system > Air heated or cooled (fan, fins, or channels)
Description: Fluid handling systems in which (1) air as a heating or cooling fluid for the system has a thermally caused movement through channels whereby it is warmed by contact with the earth and/or an object buried in the earth, such as a pipe line; or (2) the fluent material system or a part thereof is equipped with a fan or fins to aid in the heating or cooling of the device or the fluid by heat exchange with the air.
