General
Walk-in panels shall be modular in design and are to be constructed of 3 ½”, 4” or 5 ” thick prefabricated panels manufactured with 100% US made materials.
Panel Construction
Panels to be U.L. foamed-in-place polyurethane insulation between interior and exterior metal pans that have been die-formed and gauged for uniformity. Panel perimeter shall be tongue-and-groove design with 10 lb density foam rail construction. Rails to have a ½ “ indent to assure flush finish surface with metal flange and single bulb NSF gasket. Panels shall be modular in design and connected with cam-locking fasteners to assure airtight seams and structural strength to the panels. Cam locks are lever acting with eccentric hooked locks and mating pins securely anchored in the adjacent panel to assure the ease of alignment and positive seal. Cam-lock spacing shall not exceed 48” on center. Access ports for cam locks to be covered with snap-in cap plugs.
Insulation
CFC free urethane insulation shall have 97% closed cell structure. Class 1 rated urethane foam to have thermal conductivity (K-Factor) of not less than .120 BTU/hr per degree F/ inch and overall heat transfer coefficient (U-Factor) of not more than .030 BTU/hr sq ft. All foam panels to be supplied with Class 1 fire hazard insulation certified by Underwriters Laboratories as having a flame spread of 25 or less and smoke generation of 450 or less when tested in accordance with ASTM-E-84.
Panel Locking System
Assembly of walk-ins shall be accomplished by cam-locking fasteners which shall be foamed-in-place and activated by a hex wrench provided by the factory. Access ports shall be on the interior of panels to allow assembly of walk-ins from inside and shall be covered with snap caps.
Metal Finish
Standard metal is 26 gauge embossed bright galvanized finished. U.S. made G-90 galvanized coating with a certificate of origin.
Floor Construction
Floor panels shall be 4 ½“ thick and constructed with metal bonded to ¾” exterior grade plywood and then foamed-in-place. Standard floor finish is .040 smooth aluminum. Floors shall be designed and manufactured to support uniformly distributed stationary loads up to 700 pounds per square foot. If a floor is not required, alignment channel is provided. Channel is designed to be anchored to masonry floors and to provide a template for wall panels.
Entrance Doors
Standard door shall be overlap or in-fitting, flush design as specified. The door edge shall consist of a PVC perimeter into which the interior and exterior metal skins are secured and shall create a thermal break between metal facings. Magnetic gasket shall be dart and ridge design to allow quick replacement. Freezer doors shall have concealed heated jamb and threshold heater, easily accessible for replacement or service. Heated pressure relief vent port shall be provided on freezer applications. The door hinges shall be heavy-duty cam-lift design in bright chrome finish. Hinges shall have steel pins with nylon bushings and shall be of sufficient size and number to support twice the weight of the door. The door latch shall be made of similar materials and finish as the door hinges. The latch shall incorporate an inside safety release that complies with OSHA standards. All doors shall be self-closing without assistance when opened up to 90 degrees and shall remain open when opened above 90 degrees. The bottom of the door shall have a flexible sweep gasket.
Lighting
Light fixture shall be compact vapor-proof fluorescent type, shipped loose, with a shatterproof globe cover (light bulb included). Light switch with pilot light and digital thermometer shall be factory installed and flush-mounted on the exterior of the door section. All wiring within the door section, light switch, and light fixture, to be factory installed in conduit and shall terminate at the top of the frame. Field connection by others is required for complete operation; 120 volt, 60 cycle, 1-phase. All components to be U.L. Recognized.
