Panel Construction:

Worldwide Refrigeration Industries, Inc. is in the unique position of being able to offer you a variety of panel construction options for your walk in freezer or walk in cooler. In all cases, the metal panel facings are laminated under pressure to rigid insulation with an elastic adhesive.

This ensures a strong and permanent bond while allowing for expansion and contraction with variations in internal and external temperatures. When compared to a “foam-in-place” type of construction, this manufacturing process allows us to offer the most flexibility in panel sizes and insulation (types and thicknesses); assuring you of the most cost-effective solution for each of your walk in freezers and walk in coolers. It also eliminates the possibility of areas in your panels being “void” of insulation which may occur in a “foam-in-place” panel. Worldwide’s ten-year panel warranty is evidence enough of our confidence in the strength and durability of the construction of our panels. Your satisfaction will be testament to the flexibility that we offer.


Panels with Cam-Action Fasteners:

Panels manufactured using cam-action fasteners for a walk in cooler or walk in freezer provide for a fast and easy installation with provisions for future expansion or relocation of your refrigerated room.
Cam-Action Panels
These panels are available in a maximum width of 47”, with insulation thicknesses of 3”, 4” or 6”, and a maximum length of 22 feet. Through the locking action of the fastener, the panels are drawn firmly together forming a positive, airtight seal. These fasteners are made with a tongue and groove construction, which aids in the easy and accurate alignment of the panels during installation.

In order to complete the airtight seal between panels there are two options available. Worldwide Refrigeration offers a factory applied NSF approved gasket, which makes your installation quick and easy. As the panels are drawn together using the cam-action fastener the gasket is compressed assuring the seams are sealed. As an alternative, at the time of installation caulking can be applied on the insulation between the panels with a finishing bead of silicone on the seams after the room is assembled. The caulking and silicone are supplied by Worldwide Refrigeration with your walk-in to assure that the products you are using are of the best quality and suited for a refrigerated application.

Worldwide Refrigeration offers walk-in coolers and walk-in freezers that have been certified by NSF and meet their strict regulations as required in NSF/ANSI standard #7 for food equipment. In addition, our insulated freezer doors have been certified by Underwriter’s Laboratories (U.L.).


“Snap & Seal Panels”:

Using a patented locking system (patent #6,122,879) developed by Worldwide Refrigeration Industries, Inc. for walk-in coolers and walk-in freezers, we can offer a highly cost-effective alternative to the standard insulated panels using cam-locks. These panels are available in a
Snap and Seal Panels
maximum width of 45 5/8”, with insulation of virtually any thickness and a maximum length of 22 feet. To allow for easy and accurate alignment these panels are made with a tongue and groove construction. Along the edge of each panel the metal is designed to lock the panels securely in place simply by pressing the edges of two panels together allowing the metal edge to compress and then snap back. During the installation, caulking and silicone (supplied by Worldwide Refrigeration) are applied in the seams to provide an airtight seal.

These “Snap & Seal” panels are unique in their design because they were developed specifically to meet the needs of refrigeration applications. They are easy to install, snap securely together providing a truly airtight seal and may be taken down and re-installed without causing damage to the panels.
