REFRIGERATION, WALK-IN
Questions to Ask 1. Are you looking for a cooler, freezer or combo unit?
• Consult the factory to help determine the best floor type for your application, as they vary by manufacturer. 6. Will there be a product load or will the unit be for holding only? 7. Will you need a ramp on the unit? 8. What are the overall dimensions of the unit? • Walk-ins can come in exact measurements or nominal sizes. Nominal sizes are standard lengths, widths and heights and are typically the most cost-effective option. 9. What interior metal finish do you want? • Stucco Galvalume – most common and best resistance to corrosion • Stucco Galvanized—brighter finish than galvalume but at an increased cost • Smooth White – moderate price increase; helps to brighten the interior • Stucco White – best option for ceilings and walls inside cooler/freeze-reflects the most light • Stainless Steel – most expensive option; typically used in high-end jobs • Stucco Black – rarely used on interior but common in retail operations; hides dirt 10. What exterior metal finish do you want? • Same options as interior are available
(Note: All temperatures Fahrenheit.) • Cooler standard temperature is 35° • Freezer standard temperature is -10° • Keg coolers range between 32°-35°
• Red wine coolers range between 50°-55° • White wine coolers range between 45°-50° 2. What type of evaporator do you need? • Evaporators are often referred to as “coils.” These are mounted inside the unit and blow the air to cool the unit. » Low Profile – The most commonly used evaporator; typically mounts to one wall and blows towards the opposite wall. » Center Mount – This is a thinner evaporator; mounts to the middle of the box and blows air in both directions. 3. Do you want a self-contained refrigeration unit or a split remote system? • Self-Contained – Typically the most cost-effective option and ideal for smaller boxes under 12’ long. Includes a condenser and evaporator as one unit and needs a 3’ clearance over top of the unit for proper breathing. • Split Remote System – Most common and efficient option and requires the condenser be outside the unit. Be sure to confirm if the condenser will be mounted on the roof of the building or on a pad next to the unit on the ground. 4. Will the unit be located indoors or outdoors? 5. Is a floor needed? • If so, what will be moving around inside (i.e. hand carts, dollies, pallet jacks, etc.)? Accessories and Options* • Loading Ramp – can be internal or external and used for boxes that require a floor • Lights – available in both LED and fluorescent options • Thermometers – available in digital or analog and usually mounts on the door frame • Strip Curtains – plastic strips that hang down from the top of the door to keep cold air inside the unit • Vinyl Swing Door – same function as a strip curtain but in the form of a side-swinging door • Door Alarm – alerts the restaurant that a walk-in door is ajar • Temperature Alarm – alerts the operator that the box is out of operating temperature
11. W hat type of door do you want? • Swing door – right or left hinged • Slider – can be both manual or electric
12. Do you want kick plates on the door for extra protection on the bottom 36” of the door leaf? 13. Do you want a window in the door? 14. Do you want a light mounted at the door?
• Wainscoting – aluminum diamond tread that is mounted to the wall panels to protect from damage caused by rolling carts and pallet jacks • Bumper Rail – hard plastic half-circles that are mounted to the exterior walls of the unit to add protection from rolling cars • Vertical Closures – trim that covers the gap between the walk-in and restaurant wall • Ceiling Closures – trim that covers the top of the walk-in to the restaurant ceiling • Door Heater – a heated cable that runs around the perimeter of the doorframe to keep ice from forming and is only needed in freezers *May vary by manufacturer
