PART 2: PRODUCTS

2.1 MATERIALS:

A. General: The cold storage room shall be UL listed (UL Directories -
1989; Fire Resistance and Recognized Components - Volume 1), Flame
Spread of 25 or less with a 450 Smoke Developed. Electrical wiring and
components, including the refrigeration system shall also meet the UL
standards. Insulated wall panels shall be Factory Mutual 4880 listed and
approved, Class 1 building type for insulated wall and ceiling
construction in combination. The cold storage room shall be NSF 7
listed. The cold storage room shall be prefabricated, all metal clad,
sectionally constructed and be designed for easy, accurate field
assembly with provisions to facilitate disassembley for relocation, and
to add extra panels to increase size. Nominal size of cooler will be \[[
]{.underline}\] wide x \[[ ]{.underline}\] long x \[[ ]{.underline}\]
high.

B. Components:

1\. [Panels Construction]{.underline}: Wall panels shall be \[single
height\], profile design. Panels shall be made in standard widths, fully
interchangeable for fast, easy assembly. To assure perfect alignment and
maximum strength, corner panels shall be 90 degree angles with an
exterior horizontal dimensions of 12 inches on each side. Panels shall
consist of interior and exterior metal pans, of 24 gauge bright
galvanized steel, precisely formed with steel dies and roll form
equipment and thoroughly checked with gauges for uniformity and
accuracy. The metal pans, or \"skins\" shall be placed into steel molds
and liquid urethane injected between them. Urethane shall be
formed‑in‑place and, when completely heat‑cured, bind tenaciously to the
metal skins to form a rigid 4 inch thick insulated panel (R‑50). Panels
shall contain 100% urethane insulation and have no internal wood or
metal structural members between the skins. To insure tight joints,
panel edges must have formed‑in‑place tongues and grooves with a
flexible vinyl gasket also formed‑in‑place on the interior and exterior
of all tongue edges. Gaskets shall be resistant to oil, fats, water,
detergents, and sunlight and must be NSF 7 approved.

2\. [Panel Fasteners]{.underline}: Panels shall be assembled with
\"speed lok\" joining devices. Each joining device shall consist of a
cam‑action, hooked locking arm of a replaceable type (in the event of
damage) placed in one panel, and a steel rod precisely positioned in the
adjoining panel, so that by rotating the locking arm, the hook engages
over the rod and with cam‑action, draws the panels tightly together. The
cam‑action hook locking arm assembly shall connect across each panel
horizontally with a steel strap.

3\. [Ceilings]{.underline}: The ceiling shall be supported by a self
supporting steel structure. Structure shall consist of 14 gauge
galvanized steel \[6 to 8 inches\] high by 4 feet long formed angle.
Angle shall be bolted to an 8 inch \"C\" channel to form the edge load
supports. \"C\" channel shall be predrilled to bolt into the ceiling
hanger clips. Hanger clips shall be of 20 gauge galvanized sheet metal
and shall interlock into the speed‑lok system in such a way as to create
an intra‑panel suspension system. Ceiling panels shall be as specified
in panel construction. Where indicated on the drawing, there shall be a
4 inch \"C\" channel not to exceed 8 inches long which shall bolt into
the 8 inch \"C\" channel to form a compressor support stand. Between the
4 inch \"C\" channel, supply two 3 inch x 3 inch x 1/4 inch angle frame
ties. Ties shall be welded to the 4 inch channel and shall be drilled
with the proper size hole and the correct location, so that the
condensing unit may be bolted down.

4\. [Insulation]{.underline}: Insulation shall be 6 inch rigid urethane
foam poured‑in‑place, not frothed. It shall have a Underwriters\'
Laboratories label on every panel. The expanding agent shall be only
Freon 11 with an inherent pressure of 38 psi when foam is heated to 150
degrees F. The thermal conductivity factor (\"K\") shall not exceed
0.118 Btu per hour per square foot per degree Fahrenheit. Overall
coefficient of heat transfer (\"U\" factor) shall not exceed .020
(\"R50\") for 6 inch thick walls. The insulation must remain stable at
an operating temperature range of \[minus 90 degrees F. to plus 250
degrees F\].

5\. [Sliding Door]{.underline}: Single slide entrance door shall be
provided. It shall slide horizontally to the right by electric
operation. The sliding door shall be a minimum \[[ ]{.underline}\]
inches thick and \[[ ]{.underline}\] wide x \[[ ]{.underline}\] high. It
shall slide freely on metal tracks with steel rollers. Finish,
construction and insulation of the door shall be similar to the
remainder of the structure. Gaskets shall be resistant to oil, fats,
water and sunlight, and of replaceable type and form a positive, tight
seal. Hardware shall be cadmium plated cold‑rolled steel. Door shall
have an inside safety release to prevent persons from being locked
inside the cooler.

6\. [Door and Wall Guards]{.underline}: Supply \[\[[ ]{.underline}\] x
\[[ ]{.underline}\] x \[[ ]{.underline}\] thick x \[[ ]{.underline}\]
high\], steel tube door guards where shown on the drawings. Guards shall
have 12 inch x 12 inch x 3/8 inch plate and shall be anchored to the
concrete floor with 1/2 inch expandable anchors. Guards to come shop
primed for later painting. Provide wall guards of similar construction.
Wall guards shall be 24 inches high with a dual row of 4 inch \"C\"
channel. One row to be at the top, the other row to be 12 inches above
the floor.

7\. [Door Curtains]{.underline}: Doors shall be equipped with clear
vinyl strip curtains. Vinyl strips shall be 12 inches wide, .125 inch
thick and shall be installed with 2/3 overlap. Strip curtains shall be
12 inches higher than opening and 6 inches wider than opening on each
side. Strip curtain hardware shall be face mounted and bolted to door
header on inside of cooler. Mounting hardware shall be aluminum and all
fasteners shall be plated to resist corrosion. Vinyl strips shall be
capable of remaining clear at minus 40 degrees F. temperature.

8\. [Lighting]{.underline}: Lights inside cooler shall be incandescent
light \[[ ]{.underline}\] watt fixtures. Supply one 6 volt emergency
power‑out light system. The system shall be designed to provide light
instantaneously upon failure of normal electrical service. The unit
shall have a capacity of not less than 1 1/2 hours of operation and
shall have two 6 volt floor lights on the interior of the cooler.

9\. [Refrigeration]{.underline}: Refrigeration equipment shall be of
size as required to maintain \[40 [+]{.underline} 2 degrees F\].
temperature and \[35% [+]{.underline} 5% R.H.\] in the cooler at \[95
degree F.\] ambient temperature. \[Relative humidity shall not exceed
40%\]. The compressor size shall be \[5 H.P. and 208/60/3\]. The system
