WALK-IN SPECIFICATIONS
General
Walk-in coolers and freezers shall be prefabricated of modular design and construction. They shall be
designed and constructed to allow fast and easy field assembly, disassembly and enlargement by the
addition of panels.
Panel Fabrication
Standard wall, ceiling and floor panels shall be fabricated in 47” and 23” in width and shall be
interchangeable with like panels. Partition and other panels placement shall be within 1/2”
increments to meet job site conditions.
Available standard height with floor panels: 6’-6”, 7’-7”, 8’-7” . Available standard height without
floor panels with NSF vinyl screed: 6’-2”, 7’-2”, 8’-2”. Panels shall consist of Extruded Polystyrene
(XPS) rigid foam insulation, bonded permanently to interior and exterior metal “skin”. Tongue and
groove edges of panels shall be of the same panel core insulation with non-corrosive thermoplastic
cam-action panel fastener. NSF approved compression gasket shall be applied to the tongue side of all
panels on both interior and exterior.
Floor Construction
Floor panels: Shall be fabricated similar to other panels and shall be designed to withstand uniformly
distributed load of 700 lbs per square foot, suitable for foot traffic. 1,300 lbs per square foot suitable
for light rolling cart traffic. The ULTIMATE with load bearing capacity of 2,750 lbs per square foot,
suitable for hand pallet jack application.
Floorless: Provided with NSF vinyl screeds. Screed will be coved with 1/2” radius, designed to sit flat
on a finished tile/concrete floor. Screed shall be lag fastener to floor.
Insulation
Insulation shall be 4” thick, rigid Extruded Polystyrene (XPS) foam closed cell, void free, hydrophobic
or high resistance to water abortion as tested in accordance to ASTM C272 classified to UL 723 (ASTM
E84). Core material has a flame spread of 15 or less and a smoke developed of 165 or less. Self
ignition temperature of 896 degree Fahrenheit and flash ignition temperature of 734 degree
Fahrenheit as tested in accordance with ASTM D 1929. Standard with a 50 year R-value warranty.
Thermal resistance: For Coolers R-25 minimum (reported at 55 F mean temperature). For freezer R-
32 minimum (reported at 20 F mean temperature). Floor R-30 minimum.
