SPECIFICATIONS

1.0 GENERAL:

1.1 Walk-in coolers and freezers to consist of precision constructed modular 4” or 5” thick rigid polyurethane foamed-in-place interchangeable panels. Panels are designed for easy installation, expansion and relocation.

1.2 Panels shall be prefabricated modular construction consisting of 100% foamed-in-place polyurethane insulation, bonded by an adhesive to the interior and the exterior metal pan skins and heat cured for life long stability.

1.3 Each wall panel skin is to be formed using a double 90° bend on each edge to add strength and rigidity. Panels are to be in 6 inch increments, with a minimum width of 12 inches.

OPTIONS

Selection of interior and exterior surfaces and finishes

■

Various door styles and sizes

■

Wide range of computer sized and balanced refrigeration

systems

SPECIFICATION

GUIDE

1.4 All panels are to bear the UL, FM and NSF label. The panels shall incorporate cam lock type fasteners with reverse wing structural support as joining devices for the adjacent tongue and groove panels. Each device is to consist of a cam action locking arm and a steel rod in adjoining panel so that by rotating the locking arm, the hook engages over the rod and the cam action draws the panel together. The resulting panel joints shall be sealed by a foamed-in-place, continuous one piece gasket.

1.5 Panel joints are to be precisely formed male and female tongue and groove shapes fabricated to force the male edge to contact the female edge, providing additional seal. The panel joint shall have a gasket which provides a positive seal that meets NSF standards. Gasket shall be “locked” to the skins and run in a continuous piece, completely around the panel with only one break to provide the optimal seal.

2.0 INSULATION

2.1 Insulation shall be a full 4 inches or 5 inches thick, UL and FM Class 1 rigid foamed-in-place HFC-134a polyurethane with a minimum

2.0 lbs/cubic foot density. Foam polyurethane shall be injected into the panels by means of a high output, high impingement, froth mixer. Poured-in-place foam injection is not acceptable.

2.2 Environmentally friendly HFC-134A polyurethane foam insulation provides a minimum “R” value of 9 per inch of thickness at a very low mean core temperature.

2.3 Insulation shall be 95% closed cell structure. Flame spread rating according to ASTM E-84/UL 723 shall be 25 or less.

2.4 The use of R-12 and/or R-22 as a blowing agent is specifically prohibited.

3.0 FLOOR STYLES:

3.1 Less floor 4” wall walk-ins shall be supplied with PVC extruded floor sealers with semi-flexible edges, which seal to floor without the use of exposed fasteners. Sealer shall encase the wall panel on both interior and exterior surfaces with a flexible rubber collar a minimum of 3” high from finished building floor. Sealer shall meet NSF requirements for floor cove molding. Additional less floor options include female bottom rail walls for 4” and 5” thick walk-ins and various height foam sealers for 4” thick walk-ins. Consult factory for detailed specifications.

3.2 With floor walk-ins shall be a full 4 inches thick with one piece foamed-in-place edge caps. Edge caps include metal formed adhesion edges which result in the edge caps being a foamed integrated member of the floor panels. Glued-in-place edge caps are not acceptable. Floor panels shall be designed to withstand uniformly distributed loads of 800 pounds per square foot. The joint between the floor and wall shall form a NSF approved 45° angle to allow for easy cleaning.

4.0 CEILING PANELS:

4.1 Ceiling panels shall be a full 4 inches or 5 inches thick with one piece foamed-in-place edge caps. Edge caps include metal formed adhesion edges which result in the edge caps being a foamed integrated member of the ceiling panels. Glued-in-place edge caps are not acceptable.

4.2 Metal face skins are to incorporate seams using a double 90° bend at a maximum width of two feet for additional strength. The joint between the ceiling and wall shall form a 45° angle to allow for easy cleaning.

5.0 FINISHES:

5.1 The interior and exterior walls and interior ceiling shall be supplied with 26 gauge corrosion resistant stucco embossed coated steel. The interior floor surface (when applicable) shall be .100 smooth aluminum. Other finisheds are available.

6.0 DOOR CONSTRUCTION:

6.1 Entrance door shall be in fitting, flush design. The door section shall provide a full 4 inches or 5 inches of polyurethane HFC-134a insulation,

construction and finish shall be the same as the adjoining wall panels.

6.2 The door shall be 4 inches thick, constructed to incorporate heavy duty, molded ABS breaker strip, which is permanently foamed-in-place. Bottom of door shall seal with an adjustable double sweep gasket, uniquely designed to provide complete seal between door, threshold, and door jamb.

6.3 Door jamb to be a fully coved, extruded, welded, structural anodized aluminum, rigid frame design for easy cleaning and maintenance.

6.4 Threshold plate provided shall be constructed of extruded aluminum for bearing strength. Cooler/freezer shall have an anti-sweat heater wire around the entire perimeter of the door opening and under threshold.

6.5 The heater wire (standard in both coolers and freezers) shall provide enough heat to prevent condensation. All conduit for the inner-wiring of the door panel shall be totally concealed in the polyurethane foam panel, exposed conduit is not acceptable.

6.6 Door section to be field wired to surface mounted junction box on the interior door panel. The door size, location and swing to be as indicated in Specifications Drawings.

6.7 Door hardware shall be highly polished chromium plated steel. Hardware shall include a spring actuated door closer, field adjustable cam lift hinges, & deadbolt locking handle with independent key/padlock feature and inside safety release. All hardware shall be attached to extra large 1/2 inch thick, nonconducting synthetic tapping plates.

6.8 Digital thermometer calibrated to indicate interior walk-in temperature shall be provided with each entrance door.

6.9 Remote incandescent vapor proof gasketed UL listed light fixture, made of cast aluminum with plastic coated glass globe. Mounted. at the interior handle side of the door section.
