Walk-In Panel Insulation

At the heart of all walk-in panels is insulation, and the type of insulation used makes a big difference. While several different kinds of insulation are available, Norlake uses foamed-in-place polyurethane because it provides many advantages over other types.

Polyurethane has greater energy efficiency due to its superior temperature-retaining properties. Using polyurethane, Norlake provides panels with an R-value of 32, which meets or surpasses DOE regulations.
Polyurethane foam permanently adheres to metal panels adding strength and reliability
Superior moisture resistance due to polyurethane’s 97% closed-cell content
Maximum walk-in storage space because polyurethane foam allows for thinner walls
An environmentally-friendly blowing agent with a global warming potential of 1 to meet EPA SNAP and CARB guidelines
Norlake also forms walk-in panels in horizontal presses so they lay flat during the foaming process. With this method, the injected foam doesn’t have to rise as far, significantly reducing foam voids.

Walk-In Panel Construction

Norlake designs walk-in panels to fit together tightly and form a dependable seal against warm outside air.

Panels feature a soft nose construction meaning there is no hard rail or wood along the edge
When locked together, soft nose panels are more flexible and fit together better than other methods
Tongue and groove fittings and unique gasket designs also protect your valuable stored items from heat leak at the seams
Norlake’s standard wall and roof panels are four inches thick with an optional five-inch thickness for additional insulation efficiency and added support in snow load situations
Standard corrosion-resistant 26-gauge acrylic-coated galvanized steel interior and exterior finish
Many other finishes are available to match individual design schemes and budget requirements.

Additionally, the Norlake cam-locking system makes it simple to assemble your walk-in. Locks require only a factory-supplied 5/16-inch hex wrench to operate. Should the walk-in need relocation or expansion, you can disassemble panels as quickly as assembled.

Walk-In Doors

The door is arguably the most vital yet abused part of a walk-in. Doors must close completely to keep your walk-in airtight, increase energy efficiency, and form an airtight seal against warmer outside air.

Three main components on the door support the seal: hinges, door closers and gaskets.

Hinges

Norlake doors contain cam-lift hinges, which are spring-loaded. As the door closes, the springs in the hinges press the door shut for an easier, more positive closure.

Over time, any door can get out of alignment and create an air leak. That’s why Norlake doors feature field-adjustable hinge backing plates. These plates ensure a proper fit of the door to its opening during installation and also allow for any necessary future adjustments. Loosen the hinge bolts, re-align the door properly, then shim and tighten the bolts—no need to remove the door or frame.

Door Closers

Spring-activated door closer devices also make sure your door closes completely. As the door closes, a roller mounted on the door fits into a hook on the closer frame, which pulls the door shut.

Gaskets

Gaskets are a third method of maintaining a dependable seal. They are installed around the inside top and edges of the door to prevent cold air from escaping. Norlake hinges are magnetic, so they attract to the frame metal and snap the door shut within an inch.

Sweep gaskets installed along the bottom of the door keep cold air inside. Sweep gaskets are vertically adjustable to seal the gap between the door and the floor.

Other Door Features

Other door features include:

LED lighting
Deadbolt-locking handle
Digital thermometer
Vapor proof light
Pressure relief port on freezer doors
Heated frames on the freezer door

Heavy-Duty Doors

Take walk-in security and reliability to the next level with Norlake’s heavy-duty doors offering added features for increased efficiency.

Heavy-duty doors feature a welded structural anodized aluminum rigid frame for added durability. The wide strap hinges, cam-lift and spring-loaded, help the door hold up to daily usage.

Walk-In Floors

Walk-in floors, when required, are standard with a smooth aluminum surface and support 800 pounds per square foot (evenly distributed stationary load).

A reinforced floor can be provided in applications with frequent traffic from heavy handcarts, dollies or forklifts. This heavy-duty floor contains a layer of foamed-in-place plywood to distribute weight of light wheeled traffic across the floor.

For even heavier usage, Norlake’s structural floor is designed to withstand a pallet jack or equivalent transporter with an evenly distributed load of up to 5000 pounds over all four wheels. It also allows for maximum weight storage on internal shelving. At the same time, it saves labor by allowing carts or lifts to be driven directly into the walk-in and unloaded.

Walk-In Refrigeration Systems

Norlake saves valuable time by being a one-source provider of walk-ins and refrigeration systems. Our refrigeration options include self-contained, remote and multi-compressor models, ensuring a quality system matching your cold storage requirements.

Split-Pak refrigeration systems

Remote Refrigeration Systems

Split-Pak™ remote refrigeration systems consist of condensing units and evaporator coils designed for walk-in coolers and freezers.

Condensing units feature a condenser coil, compressor, receiver tank and other components assembled on a common base.

Evaporator coils are ready to mount in position on a walk-in and are available with air (off cycle) defrost, electric defrost or optional reverse cycle defrost when equipped with the LogiTemp® Plus With Reverse Cycle Defrost system.

If you have an application calling for a water-cooled system, Norlake can provide one at the same lead time as an air-cooled system.

Self-Contained Refrigeration Systems

Capsule Pak™ and Capsule Pak ECO™ self-contained refrigeration systems.

Capsule Pak™ self-contained systems are easy to install and service. Indoor and outdoor systems feature a cord and plug electrical; indoor models do not require a floor drain.

Capsule Pak ECO™ systems for indoor walk-in coolers and freezers are highly sustainable with a significantly reduced Global Warming Potential of 3. Their patent-pending design combines efficient components with R290 natural refrigerant for the most eco-friendly and energy-efficient systems.

Capsule Pak ECO models also feature a smaller footprint (up to 28% shorter and 20% narrower) for more working space and easier handling.

Capsule Pak and Capsule Pak ECO systems with LogiTemp® electronic controllers boost energy efficiency.

Electronic Controller Systems

LogiTemp electronic controllers increase food safety while reducing energy and installation costs compared to all-mechanical systems. LogiTemp is standard on all self-contained Capsule Pak™ refrigeration systems, with a more limited feature set on Capsule Pak ECO™ systems. On remote Split-Pak™ systems, it is standard on freezer systems 6 H.P. and above and optional on other systems.

Suppose you are in hot, humid, or heavy-use situations. In that case, our patented LogiTemp® Plus With Reverse Cycle Defrost option will help you avoid iced evaporator coils, particularly during long hot summers.
