WALK-IN FREEZER SPECIFICATIONS

OUTDOOR INSTALLATION

GENERAL:

A. Walk-in freezer shall be constructed of pre-fabricated, precision-formed, modular panels designed for rapid field assembly. Walk-in freezer shall be manufactured and furnished by Bally. 10 day prior approval for any other manufacturers.

CONSTRUCTION PLANS AND INSTRUCTIONS:

GUARANTEES:

A. Walk-in freezer panels shall be guaranteed for a period of ten (10) years after final approval against poor workmanship and defective materials. Any defect within this period shall be corrected at no charge to Owner. Refrigeration system shall be guaranteed for parts and labor for a period of one year (1) year with an additional four (4) year compressor warranty.

CODES AND STANDARDS:

A. NSF Standards: Comply with applicable National Sanitation Foundation (NSF) Standard 7 construction and recommended criteria. Provide equipment with a NSF “Seal of Approval."

B. UL Labels: Where available, provide UL labels on prime electrical components.

Provide UL "recognized marking" on other items with electrical components, signifying listing by UL where available. Provide UL approval of door electrical circuit assembly.

C. ASTME-84 (UL723): Comply with fire hazard classification ASTME-84 (UL723).

Panels shall be supplied with a fire hazard classification in accordance with ASTME-84 (UL723). Panels shall be classified according to ASTME-84 (UL723) shall be flame spread rating of 25 or less with a certifying Underwriters Label Factory Mutual Approved Toxicity Rated Non-CFC polyurethane foam required.

Insulation tested according to E-84 “shall not flame, glow, smolder or smoke” at a minimum test temperature of 250°F. (Flame Spread 25 indicates lower surface burning of materials. This standard is used solely to measure and describe properties of products in response to heat and flame under controlled laboratory conditions. This rating provides the walk-in panels with additional thermal resistance and may reduce the need for sprinkler systems.)

D. ASTM D-C518: Panels & doors must meet or exceed minimum R-Values for cooler (R25) and freezer R-32) per Federal Regulation 431.304.

E. Refrigeration systems must meet the January 1, 2026 requirement that all new commercial refrigeration products use a refrigerant <300 GWP (R-454A) for systems under 200 Lbs. and <150 GWP (R-454C & R-455A) for systems above 200 Lbs.

PRODUCTS:

A. Furnish one (1) outdoor walk-in freezer to be actual 11’-7“x 14’-5 ½” x 8’ 6“.

B. Walk-in freezer is to comply with the US Energy Independence & Security Act.

C. Interior wall finish: 190 Series embossed white galvanized. Exterior finish: 190 Series embossed white galvanized. Interior ceiling finish: 190 Series embossed white galvanized. Exterior ceiling finish: 190 Series embossed white galvanized.

Single-span reinforced ceiling. 4” thick floor panels with 3/8” inside coved radius built in around the perimeter of skins and NSF certified. Interior floor finish:

0.125” textured aluminum with integral kickplates.

D. Panels shall be equipped with Bally Speed-Loc diaphragmatic joining devices. The distance between locks shall not exceed 46”. Each device shall consist of a cam action, hooked locking arm placed in one panel, and a steel rod positioned in the adjoining panel, so that when the arm is rotated, the hood engages the rod and draws the panels tightly together with cam action. Arms and rods shall be housed in individual steel pockets. Pockets on one side of the panel shall be connected to pockets on the other side in width, by use of 2” wide metal straps set into and completely surrounded by insulation. When panels are joined these straps shall form lock-to-lock connections for superior strength. Locking device shall be accessible from the inside to facilitate installations in confined areas and shall be provided with flush press-fit caps. Surface mounted plastic plugs will not be accepted.

E. Panels shall consist of interior and exterior metal skins precisely foamed with steel dies and roll-form equipment and thoroughly checked with gauges for accuracy.

Metal skins shall be treated on the inside surface with a bonding agent to ensure a stable adhesion with the chemical bonding agents of the urethane. Urethane shall be Enovate 3000 or Solstice foamed in place (poured, not frothed) and, when completely cured, shall bind tenaciously to metal skins to form an insulated panel.

Panels shall contain 100% urethane insulation and have no internal wood or structural members between skins unless required as structural support for external accessories. To ensure tight joints, panel edges must have foamed-in place tongue and groove with flexible vinyl gasket foamed-in place on the interior and exterior of all tongue edges. Gaskets shall be resistant to damage from oil, fats, water and detergents and must be NSF-approved. Gaskets shall not be stapled or glued to metal skins. All panels (except corner panels) shall be made in 23” and 46” widths, fully interchangeable for fast, easy assembly. 11-1/2", 17- 1/4", 34-1/2" wide are to be furnished only if required to fit allocated space. To ensure perfect alignment and maximum strength, corner panels shall employ a right-angle configuration with exterior horizontal dimensions of 12” on each side.

a. Unit shall be fitted with cooler door with 36" x 78" swing out type hinged entrance door. Doors shall be flush mounted, in-fitting type will have a 14-gauge unitized structural “U” channel steel door frame with 1/8” steel plates where all hardware is mounted. The steel frame with an internal thermal breaker will prevent twisting, sagging, and eliminates the need for structural members. Door shall be equipped with a magnetic steel core gasket across the top and both sides of the door. Bottom of the door shall be fitted with adjustable, double vinyl wiper gasket. NSF approved removable gasket.

b. Each door frame shall be provided with an LED vapor proof light fixture and an inside safety release.
