Filter kit, assembly, and method for installation within a support surface associated with a heat exchanger unit not limited to such as an air cooled liquid chiller

A filter assembly for securing to first and second consecutively positioned and angled intake faces of a heat exchanger unit, the intake faces each having an outer flange surface surrounding a central opening, along with an intermediate interconnecting surface, said filter assembly comprising:

• a flexible screen having a reinforced edge through which are formed perimeter spaced and grommet defining apertures, said screen approximating in dimension a combined area of each of the first and second angled intake faces, along with an additional area equaling the intermediate interconnecting surface located between the intake faces;
• a plurality of fasteners adapted to being supported upon at least one extending side the outer flange surfaces of each of the angled intake faces;
• and
• upon aligning said screen with said fasteners, engaging portions of said fasteners securing said flexible screen to cover the first and second intake faces.

A method for installing a filter assembly over an intake opening of a heat exchanger unit, comprising the steps of:

• constructing a multi-sided frame exhibiting a thin planar cross section;
• securing a multi-sided track secured to the frame, the track including an open forward slot within which are supported a plurality of fasteners;
• providing a screen approximating in dimension an outline of the track, the screen including a reinforced edge within which is configured a plurality of spaced apart grommets aligning with and receiving therethrough engaging portions of said fasteners extending through said slot to secure said screen to said track and frame;
• positioning the frame against an outer flange surface surrounding the heat exchanger opening;
• and
• attaching a plurality of clips adapted to engage aligning edges of the frame to the flange surface in order to secure the frame, track and screen in place over the heat exchanger opening.
