A screen includes a reinforced edge, within which is configured a plurality of spaced apart grommets aligning with and receiving therethrough engaging portions of the fasteners. In one variant, a frame is constructed for supporting the fasteners and attached filter and which is subsequently secured by clips against a flange surface surrounding the intake opening. In a further variant, the screen is configured in wrap-around fashion for supporting against first and second consecutively arranged intake openings along with an interconnecting intermediate flange surface. ## Claims ### Claim 1 A filter assembly for securing to a heat exchanger unit, comprising: a multi-sided assembleable frame, each of said sides exhibiting a thin planar cross section; a multi-sided track secured to said frame, said track including an open forward slot within which are supported a plurality of fasteners; a screen approximating in dimension an outline of said track, said 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; and upon positioning said thin planar frame against an outer flange surface surrounding a heat exchanger opening of the unit, a plurality of clips adapted to engage aligning edges of said frame and flange surface in order to secure said frame, track and screen in place over the heat exchanger opening. ### Claim 2 (depends on 1) The filter assembly as described in claim 1, the heat exchanger unit further including an air cooled liquid chiller unit having coil arrays associated with the heat exchanger openings which are arrayed in a V configuration. ### Claim 3 (depends on 2) The filter assembly as described in claim 2, further comprising a plurality of clamps for temporarily securing together said aligning edges of said frame and intake opening prior to installation of said clips. ### Claim 4 (depends on 1) The filter assembly as described in claim 1, said sides of said frame further comprising overlapping apertures which, upon inter-assembly of said tracks, aligning to permit installation of additional engagement fasteners. ### Claim 5 (depends on 4) The filter assembly as described in claim 4, said engagement fasteners further comprising rivets. ### Claim 6 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. ### Claim 7 (depends on 6) The filter assembly of claim 6, further comprising a multi-sided track adapted to being secured to the outer flange surface of each of the intake faces for supporting said plurality of fasteners. ### Claim 8 (depends on 7) The filter assembly of claim 7, said track further comprising an open forward slot within which are supported a plurality of fasteners such that a rotatable twist or toggle lock portion of each fastener projects through said slot. ### Claim 9 (depends on 7) The filter assembly of claim 7, each of said multi-sided track further comprising an overall U shape adapted to mount to each of extending side and remote interconnecting edges of the outer flange surfaces. ### Claim 10 (depends on 6) The filter assembly of claim 6, the heat exchanger unit further including an air cooled liquid chiller unit having coil arrays associated with the heat exchanger openings which are arrayed in an opposing V configuration. ### Claim 11 (depends on 6) The filter assembly of claim 6, said flexible screen further comprising intermediate cutout locations adapted to conform with a surface geometry of the heat exchanger unit. ### Claim 12 (depends on 6) The filter assembly of claim 6, further comprising any of adhesives, magnets or screws for affixing said fasteners to the outer flange surfaces. ### Claim 13 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. ### Claim 14 (depends on 13) The method as described in claim 13, further comprising providing a plurality of clamps for temporarily securing together the aligning edges of the frame and intake opening prior to installation of the clips. ### Claim 15 (depends on 13) The method as described in claim 13, further comprising configuring the sides of the frame with overlapping apertures which, upon inter-assembly of the tracks, aligning to permit installation of additional engagement fasteners. ### Claim 16 (depends on 13) The method as described in claim 13, further comprising providing a protective layer approximating the dimensions of the assembled frame over a plurality of coils exposed by the intake opening and prior to installation of the assembled frame, track and screen. ### Claim 17 (depends on 16) The method as described in claim 16, further comprising configuration the protective layer as any corrugated or other semi-rigid or rigid material not limited to a heavy duty paperboard. ### Claim 18 The method as described 16, further comprising applying a temporary adhesive to secure the protective sheet over the heat exchanger opening and in order to shield the coils of the chiller during installation of the frame.
