Walk-in Coolers & Freezers

Foam Rail Indents

While the gaps on the sides of the foam may not seem like something important, they actually are necessary. These gaps allow our machines to bend the exterior metal into the foam so when its stapled it does not extend outside the finished edges of the rail. This indent also allows for a tighter connection which prevents thermal transfer

Tongue and Groove Design

Our tongue and groove design is a cam-locking system that provides an air-tight seal between the panels, restricting air infiltration into the insulation core. This seal keeps the box running at optimal temperatures which keeps the condens-ing unit running more extending the life of the unit. The rough top on the rails is also done intentionally so that the foam rails have better adhesion with the urethane foam.

Our high density foamed-in-place polyurethane foam rails are the optimal choice for manufacturing our Walk-in panels. Here are just some of the reasons why:

• They have incredible flexural strength which eliminates the need for perimeter wood framing (old style construction).
• The panels can easily be made to exact size requirements. There are no restrictions to dimensions, such as perimeter and door location.
• Odd size panels can be manufactured in the same method as standard panels with little effect on cost. This also provides the architect and consultant the maximum design space use.
• Foam rails have better structural integrity, higher thermal efficiency, less frequent panel damage during shipping and installation, and no leakage of the core foam onto the panel skin that has to be cleaned.
• Our high density rail panel can withstand a temperature range from -65C to +85C (-85F to +185F) and is dimensionally stable.
• Foam rails do not warp, twist or deteriorate as wood can when exposed to moisture and cold; panels maintain structural integrity and boxes last longer.

Panel Construction

Our Walk-in Panels are U.L. foamed-in-place polyurethane insulation between interior and exterior metal pans that have been die-formed and gauged for uniformity. Panel perimeter shall be tongue-and-groove design with 10 lb. density foam rail construction. Walkin Panels are Constructed of 3 ½“ , 4, or 5 in panels, insulated with foamed-in-place polyurethane.

Cam Lock Mechanism

Our panels are connected to one another by placing the tongue of the insulation core of one panel
into the groove of the core insulation of the adjacent panel. The resultant tongue and groove joint are sealed at both sides by double barreled NSF approved gaskets. Each one of our panels comes with 3 Cam locks to ensure a better seal.

We hold all our walk-in boxes to the highest quality. That is why here at Commercial Cooling we stand up and inspect our boxes using our 7-point inspection quality control list to ensure that each box meets our quality standards. Commercial Cooling is the only company in the country that uses such quality control measures prior to shipment.

We check the drawing of the box and ensure that the box was manufactured to the exact specification the customer requested.

We inspect the metal, foam rails and wood (if applicable) to ensure that they are free of any defects that could affect the integrity of the Walk-in box.

We check the door(s) of the box and look for any scratches on the finish and inspect the air vent(s) and any electrical wiring (if applicable) to ensure everything is in working order.

We inspect the walk-in panels and ensure they are not damaged or defective in any way.

We assemble the panels and ensure the panels are straight when they lock together and we check for any gaps or other defects.

We check to make sure all accessories are included with the Walk-in box (Screws, vents, or other loose parts).

The quality control manager does one last inspection themselves. The shipper manager checks again to make sure everything that needs to be included with the box is included. Finally the shipping assistant will palletize the box and prepare it for shipment.
