Standard Specifications
General:
The walk-in coolers and/or freezers specified under this portion of the specifications shall be manufactured by Southwest Insulated Panels, LLC. The walk-in shall be designed and constructed to allow fast and easy field assembly, disassembly, relocation and enlargement of the unit by the addition of like modular panels.
Panel Construction:
All panels shall consist of metal pans, finish to be as specified, formed to precise dimensions. Insulation shall be "Foamed-In-Place" urethane bonding permanently to the complete inner surfaces of both interior and exterior metal pans to form a strong rigid panel. Each panel shall be 100% urethane foam insulation exclusive of metal pans. Panels shall not have non-insulating members like wood or metal support straps. Perimeter structure shall be formed with high-density urethane rail insulation forming strong tongues and grooves to assure airtight and vapor proof joints and to prevent pre-installation damage and deterioration of exposed urethane surfaces.
Standard wall panels shall be made in 46", 34-1/2", 23", and 11-1/2" widths. Standard ceiling panels shall be made in 46", 35", 34-1/2", 23", 23-1/2",and 11-1/2" widths. Standard floor panels shall be made in 46", 35", 34-1/2",23",23-l/2", and 11-1/2" widths. All panels shall be interchangeable with like panels for fast and easy field assembly.
Standard height with floor is 7' 6", 8' 6", 9' 6", or continue in 12" increments.

Panel Locking Assemblies:
Assembly of tbe walk-in shall be accomplished by earn-action panel fasteners (Cam-Locks) consisting of a cam-action hook arm assembly set in one panel (male joint) and a self-aligning, self centering, pin assembly set in the matching panel (female joint). Counter clock-wise rotation of the cam-action hook arm shall pull and lock panels together to form an airtight, vapor proof seal. Counter clock-wise rotation of the cam locks shall be operated from inside the walk-in through access ports that are later sealed with vinyl snap-in hole covers. No metal straps or connecting rods shall be used inside the panels for assembly.
Panel Gaskets:
Double beaded N.S.F. approved gaskets shall be used on both the interior and exterior of all panels. These gaskets must be located at all male sides of panels. Gaskets shall be impervious to stains, grease, oils, mildew, sunlight, etc.
Entrance Doors and Frames:
Each walk-in shall be equipped with a standard 34" x 76" flush mounted, hinged-type entrance door(s) and shall be mounted in a standard 46" panel (door) section frame. All components used in the door and door section are to be U.L. and N.S.F. approved.
