How long does it take to get a quote?
QRC is very computer oriented. Our computer programs allow the quotation of a custom walk-in while the customer is on the phone. Many of our quotes are done this way. However, some items are not manufactured by our company and need to be specially priced from our suppliers. These quotes are not able to be quoted automatically but should be quoted within 24 hours.
Can QRC email me a quote?
Yes. Use our form here to request a quote. It will immediately be routed to the appropriate sales person, and the quote will soon follow.
Can QRC fax me a quote?
Yes. Fax us a quote request at 336-788-5405. It will immediately be routed to the appropriate sales person. The quote will soon follow.
Can QRC send me a drawing?
Being one of the most computerized walk-in companies, you can go to our web page and enter the information, then a drawing of the walk in you desire will be generated. If you desire help, call our sales department and a salesperson can take the information and immediately send you the drawing. On the extremely complicated drawings call the sales department and they will take the information and quickly give you a drawing. QRC is dedicated to providing you with all the information you need to make your walk-in purchase decision.
How do I contact someone to talk to?
You can call 336-788-5407 for a QRC customer service representative. They are highly trained and capable of answering your questions.
Can I get other sizes than are listed?
Yes. QRC makes all sizes of walk-in coolers and freezers.
Do you do custom sizes?
Yes. QRC has an automated custom manufacturing plant and resources to provide you custom products of the same high-level quality that you find in our standard products.
What will it cost to run my walk in?
The cost of running a walk-in varies due to many factors.
- The type of insulation in the walk-in.
- Where the walk-in is located.
- The temperature and the weight of the product being cooled.
- How often the door is opened.
- Efficiency of the refrigeration system.
- Cost of electricity.
- The age of the walk-in.
This is just a few. 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.
Where can I get specifications of your walk-ins?
Call 336-788-5407 for a QRC customer service representative.
Is NSF and UL Important?
Yes. NSF stands for National Sanitation Foundation and is looked upon as the ultimate food service 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 food service and building industries as a testing laboratory of products and materials.
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 the time the insulation was manufactured 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, manufacturers 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
What kind of insulation do you use?
QRC 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
Why don't you use all urethane insulation?
QRC provides walk-ins using three types of insulation expanded polystyrene, foamed-in-place polyurethane and extruded polystyrene. There are few, if any, manufacturers making walk-ins 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. The expanded polystyrene is best for lower-cost up front coolers, and the extruded polystyrene is bes 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.
What type of refrigeration do you use and/or recommend?
QRC has the capability of using several different manufacturers and designs when supplying refrigeration systems. 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 best fits your needs and, if you have no brand preference, they will 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.
How do you find out how big of a refrigeration system I need?
You can call your customer service representative at QRC at 336-788-5407 and he will help you size your unit.
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.
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 you consider 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, QRC will only provide ramps with reinforced floors.
