8. How safe is it to order a walk in on-line?
Quality Refrigeration Concepts site is independently certified and encrypted by a third party to provide secure communications between you and our dealers. It is the most secure way to place orders on the Internet.

9. What will it cost to run my walk in?
The cost of running a walk-in varies due to many factors.
 1. The type of insulation in the walk-in.
 2. Where the walk-in is located.
 3. The temperature and the weight of the product being cooled.
 4. How often the door is opened.
 5. Efficiency of the refrigeration system.
 6. Cost of electricity.
 7. The age of the walk-in.
 This is just to name a few. Actually over a hundred factors are considered when   sizing refrigeration systems for a walk-in. Most walk-ins are designed to run 80% of the time or between 16 and 18 hours per day. For a quick estimate of the cost of running the walk-in use the following formula.
((A*V)*17)*(C/1000)
 This takes the total amperage (A) of the refrigeration system times the total voltage (V) of the refrigeration system times 17 (the amount of time the unit will run per day) times the Kilowatt cost of electricity in your area divided by 1000. This will give you an estimate of what the walk-in will cost to run per day in your area.

10. Where can I get specifications of your walk-ins?
Call 704-633-7182 for a Quality Refrigeration Concepts customer service representative.

11. Is NSF and UL Important?
Very, NSF stands for National Sanitation Foundation and is looked upon as the ultimate foodservice design and equipment approval agencies by the local building and heath departments. In many states and counties if it does not have the NSF seal it is not allowed for public use.
UL stands for Underwriter Laboratories and is well known in both the foodservice and building industries as a testing laboratory of products and materials.

12. What is the R-value of your walk in?
R-value is the resistance to heat flow. The higher the R-value the better the insulation is in a walk-in cooler or freezer. K-factor is the ability of heat to flow the lower the better for walk-in coolers or freezers.
R-value of any insulation varies according to age of the insulation, wetness of the insulation, type of insulation, mean temperature of the insulation and condition of the insulation.
Most companies publish the R-values of their walk-in coolers and freezers. These R-values are usually at time of manufacturer of the insulation and not what the R-value is after the unit has been in the field for one year. In the roofing industry after much discussion manufactures publish a 120-day aged R-value at a 75 degree mean temperature. Even these R-values do not take into consideration the moisture content of the insulation, which can lower R-value by as much as 75%.
When buying a walk-in cooler or freezer ask what the aged R-value of the insulation will be 5 years after manufacturer and how resistant to moisture the insulation is. You will be surprised how these numbers vary from their published R-values.
R-values of different types of insulations are as follows:
  Published Projected 5 Year Actual
Polyurethane 32 6
Expanded Polystyrene 19 10
Extruded Polystyrene 32 15

13. What kind of insulation do you use?
Quality Refrigeration Concepts does all three types of insulation that are used in walk in coolers and freezers today, expanded polystyrene, extruded polystyrene and foamed in place polyurethane.

14. Why don't you use all urethane insulation?
Quality Refrigeration Concepts provides walk-ins using three types of insulation expanded polystyrene, foamed-in-place polyurethane and extruded polystyrene. There are few, if any manufacturers manufacturing walk in with all three types of insulation. This allows our company the ability to manufacturer each walk in with the correct insulation best suited for the customer's needs. Since we believe that foamed-in-place polyurethane is a good insulation when it is used not only to insulate but used in an item that has many parts that need to be molded together, we use it to manufacturer our cooler and freezer doors. For cooler walls and ceilings we use expanded polystyrene and extruded polystyrene insulation. Expanded polystyrene for lower cost up front coolers and extruded polystyrene for stronger lower operating cost coolers, freezers and extra strength floors. We do not think that foamed-in-place polyurethane is the insulation of choice for walk in coolers and freezer walls and ceilings.

15. What type of refrigeration do you use and/or recommend?
Quality Refrigeration Concepts has the capability of using several different manufacturers and designs when supplying refrigeration system. Our engineers have chosen several manufacturers as our key suppliers. When you discuss the purchase of a walk in with our sales personnel they will help you decide which design better fits your needs, if you have no preference, supply you with the most competitive price for the system you need from our suppliers. If you have a manufacturer preference we can also quote you their system with the design you need.

16. How do I find out how big of refrigeration system I need?
You can call your customer service representative at Quality Refrigeration Concepts at 704-633-7182 and he will help you size your unit.

17. Do I need a floor in the cooler?
Coolers can be installed on ground contact concrete floors and pads but it is recommended that an insulation barrier be installed under the walls of the unit to reduce condensation on high humidity days. On coolers located on wood frame floors a cooler floor is a necessity. Condensation will develop under the floor and eventually rot the floor out. On freezers a floor or an insulated concrete floor with insulation barrier is required. Check local codes or contact an architect for concrete insulated floor plans for your area.

18. Why do floors need to be reinforced when equipped with a ramp?
Doors and floors are the most used and abused parts of a walk in cooler or freezer. Standard floors are designed with a 600-LB load per square foot. That sounds like a lot of load carrying ability until it is considered that a 200-LB load on a two-wheel cart can develop a load of 50-lbs per square inch or 7,200-lbs per square foot. Usually when a ramp is requested, it is assumed that two-wheel carts carrying heavy loads will be used in the walk in. Due to this factor, Quality Refrigeration Concepts will only provide ramps with reinforced floors.

19. Do you use wood in your boxes?
It is always better not to include wood in walk in coolers and freezers. Wood is a poor insulator and does not do well in the consistently damp or wet environments commonly found in walk in coolers and freezers. Some walk in manufactures actually use 2X4-inch tongue and grove edging around each panel edge throughout their walk-ins. Some walk in companies use wood throughout their walk in doors. Quality Refrigeration Concepts uses no wood products in our standard walk in walls, ceilings, doors and floors. We do use 3/4 inch plywood in our optional extra strength floors and some custom built doors.

20. Is wood bad in walk-ins?
First of all wood is not a good insulator. Second wood absorbs moisture. In a freezer it can then freeze and swell causing the joints to misshape and leak precious cold. Third, damp wood is a food source for mold and can cause mold to grow inside the panel and possibly cause negative health affects. Finally, wood can absorb water vapor lowering its already low R-value. This water vapor, through freeze and thaw cycles, cause water to run down and either freeze inside the walk in or run outside the walk in causing an unsafe slippery floor increasing injuries and liability issues. Therefore wood is not desirable in walk-ins.
