Abstract

A retrofit kit replaces the thermostatic element in a radiator steam trap having a hollow body with a horizontal side steam inlet, a vertical bottom condensate outlet, and a top cover. The retrofit kit contains an insert with a restricted passageway that rests in and over the condensate outlet, a cylindrical spring for blocking the flow of particles into the restricted passageway of the insert, and a compression coil spring for holding the insert and screen in position. The restricted passageway in the insert contains a plurality of horizontal radial inlets in the upper portion of the insert that communicate with a vertical conduit extending downward through the insert, the vertical conduit having an opening at the bottom, but not at the top, of the insert.
