Merchandising Refrigeration Guide

Turn cold storage into hot sales with high-visibility display coolers
Refrigeration isn't just about keeping food cold; it's about selling it. Merchandising refrigeration. From glass-door drinks coolers to open-air grab-and-go cases, is the silent salesperson of your foodservice operation. Unlike back-of-house storage units designed purely for preservation and efficiency, merchandisers are engineered for maximum visibility, clear lighting, and impulse appeal. Whether you run a convenience store, a supermarket deli, a floral shop, or a high-volume cafeteria, the right display cooler catches the customer's eye and drives the "last 10 feet" of the sale.
Merchandising refrigeration combines product preservation with powerful visual marketing. Often utilizing specialized lighting, anti-fog glass, and barrier-free designs, these units drive impulse purchases for beverages, flowers, and grab-and-go meals. Choosing the right unit, whether a floral cooler with gentle airflow or a high-traffic open air case, boosts revenue per square foot.
Types of Merchandising Refrigeration
Merchandisers are defined by what they sell and how the customer accesses it. From barrier-free air curtains to humidity-controlled floral cases, each type serves a specific sales goal.
Glass Door Merchandisers (Refrigerators & Freezers)
The workhorse of the convenience store and supermarket industry. These upright units feature double- or triple-pane glass doors to keep cold air in while showing off colorful product packaging.
Swing Door Merchandisers
Swing door units are the standard for energy efficiency. The self-closing doors pivot on a hinge, creating a tight magnetic seal that keeps cold air in and dramatically lowers your utility bill compared to older models. They are ideal for aisles where there is ample room for the door to open fully without blocking customer traffic.

- Best For: Maximum energy efficiency and operations with wide aisles.
- Pros: Self-closing mechanisms ensure doors don't stay open; generally cheaper to operate due to better seals.
- Cons: Doors swing out into the aisle, requiring more floor space and potentially blocking traffic flow.
Slide Door Merchandisers
Slide door units are problem-solvers for tight spaces. Because the doors slide laterally on a track, they never intrude into the walkway, making them perfect for narrow aisles or high-traffic zones where multiple customers might be shopping side-by-side.

- Best For: Tight aisles, small convenience stores, and high-traffic areas.
- Pros: Does not intrude into the walkway; easy for multiple customers to shop simultaneously.
- Cons: Doors can be left slightly ajar by customers; typically slightly less energy efficient than swing doors.
Open Air Merchandisers (Air Curtain)
Also known as "Grab-and-Go" cases, these units have no physical barrier between the customer and the product. They use an "air curtain", a focused stream of air that circulates from top to bottom, to keep cold air inside the case.

These are the ultimate high-volume sales tools. By removing the "barrier to entry" (opening a door), you reduce the psychological friction of the sale. Customers can reach in and grab a yogurt, sandwich, or drink without breaking their stride, which significantly boosts impulse purchases.
- Best For: High-impulse items like sandwiches, bottled drinks, salads, and yogurt parfaits near checkout lines.
- Key Advantage: Lowest barrier to sales; maximizes grab-and-go volume.
- Trade-off: Less energy-efficient than glass door units due to cold air loss into the ambient room.
Optimizing Air Curtain Performance
Because they have no door, air curtains are sensitive to their environment. Follow these placement rules to prevent spoilage.
| Factor: | Recommendation: | Why? |
| Room Temperature | Max 75°F | Hotter room air overpowers the air curtain barrier. |
| Humidity | Max 55% RH | High moisture causes coil freeze-ups and sweating. |
| HVAC Vents | Keep Away | Ceiling vents blowing down will disrupt the air curtain. |
| Sunlight | Avoid Direct Sun | UV heat load is too high for the unit to combat. |
| Stocking | Keep Fully Stocked | Mass holds cold; an empty case works harder to stay cool. |
Display Cases (Deli, Bakery, Sushi)
These are "service" merchandisers where staff typically serve the product (though self-serve options exist). They are specialized by what they hold:
Deli & Meat Cases
Fresh meats and cheeses are highly sensitive to airflow. Standard fans will dry them out, turning expensive product into waste. Deli cases typically use Gravity Coil refrigeration, where a cooling coil at the top of the cabinet allows cold air to gently "fall" over the food without a drying fan.

- Technology: Gravity Coil refrigeration.
- Why It Matters: Prevents the drying effect of fans, keeping unpackaged meats, cheeses, and salads fresh and moist without strictly wrapping them.
Bakery Cases
Bakery display cases come in two main varieties: refrigerated (for cream-filled items) and "dry" (room temperature for bagels and cookies). Refrigerated versions use gentle Forced Air with higher humidity to keep pastries moist and frosting intact.

- Technology: Forced air with high humidity control.
- Why It Matters: Preserves the texture of delicate frostings and fillings that would melt at room temperature or dry out in a standard fridge.
Sushi Cases
Sushi is both a visual art and a food safety challenge. These specialized countertop units provide heavy-duty cooling in a small footprint to keep raw fish safe, but they manage humidity carefully to ensure the vinegar rice (shari) doesn't dry out and become hard.

- Technology: Countertop specific cooling with humidity balance.
- Why It Matters: Raw fish requires strict temperature control for safety, but the airflow must not dehydrate the rice.
Ice Cream Merchandisers
Dipping Cabinets
The centerpiece of any scoop shop. Dipping cabinets are designed for service, holding tubs at a perfect scooping temperature (usually slightly warmer than deep storage) so the ice cream is pliable. They often feature a glass sneeze guard and a viewing window for customers to pick flavors.

- Function: Service-oriented display for easy scooping.
- Feature: Holds temperature steady even with the lid frequently opened; includes flavor tag rails.
Novelty Freezers
These are the self-service glass-top or upright freezers found in convenience stores. They are designed for pre-packaged goods like ice cream bars, pints, and popsicles. The key here is visibility, customers look down through sliding glass tops or into an upright glass door to make a quick selection.

- Function: Self-service for pre-packaged items.
- Feature: High visibility; baskets for organization; often branded with graphics.
Floral Merchandisers
Critical Distinction: You cannot store flowers in a standard beverage cooler. Standard refrigerators blow high-velocity cold air that dehydrates delicate petals, killing flowers effectively.

Floral Merchandisers utilize "Low Velocity" airflow and specialized baffled evaporator coils. This creates a high-humidity environment with gentle cooling that mimics a spring day, keeping stems crisp and petals vibrant for days longer than a standard fridge.
- The Difference: Low velocity airflow + High humidity.
- Best For: Florists, grocery store floral departments, and gift shops.
Bar & Wine Display
Merchandising alcohol requires specific lighting and temperature zones.
Wine Refrigeration
Wine is a living product that is easily damaged by light and vibration. Commercial wine refrigerators often use UV-filtering glass (often tinted) to prevent "light-strike" from ruining the vintage. In some cases, they feature wooden or coated wire racks designed to dampen compressor vibration, which can disturb the sediment in fine wines.

- Feature: UV-filtering glass and vibration dampening.
- Goal: To display the label clearly while protecting the liquid inside from environmental stress.
Back Bar Coolers
These are the unsung heroes of the bar. Sitting under the counter, they act as a visual menu for seated customers. With glass doors and bright LED lighting, they showcase your bottled beer and white wine selection, encouraging customers to order what they see.

- Feature: Under-counter height with glass visibility.
- Goal: Serve as a visual menu for bottled beverages; quick access for bartenders.
Bottle Coolers
Traditional deep-well coolers are often a solid stainless steel, great for speed but poor for sales. Slide-Top models change the game by allowing customers standing at the bar to look down into the well. This visibility turns a storage unit into a merchandiser.

- Feature: Slide-tops for visibility.
- Goal: Allows customers to see the beer selection, driving sales in fast-paced bar environments.
Merchandiser vs. Standard Storage: What's the Difference?
While they may look similar, a glass door merchandiser is not the same as a kitchen reach-in refrigerator. Misusing them can lead to health code violations.
| Feature: | Reach-In Storage Refrigerator: | Merchandiser Display Cooler: | Merchandiser Display Cooler: |
| Primary Goal | Food Preservation & Component Storage | Product Sales & Visibility | Product Sales & Visibility |
| Typical Location | Back-of-House (Kitchen) | Front-of-House (Customer Area) | Front-of-House (Customer Area) |
| Interior Finish | Stainless Steel / Aluminum (Food Safe) | Painted Steel / Plastic (Display Safe) | Painted Steel / Plastic (Display Safe) |
| Food Type | Open Food Pans, Prepped Ingredients | Packaged/Sealed Products Only | Packaged/Sealed Products Only |
| NSF Rating | NSF-7 (Safe for Open Food) | NSF-7 Display (Packaged Only) | NSF-7 Display (Packaged Only) |
| Shelving | Heavy Duty Wire / Pan Slides | Coated Wire / Gravity Feed | Coated Wire / Gravity Feed |
Important: Most merchandisers are NOT approved for storing open food pans (like a tub of tuna salad). They are strictly for sealed bottles, cans, and wrapped sandwiches.
Selecting the Right Unit
Compressor Location: Top vs. Bottom mount
Where the engine sits matters for your environment.
Bottom Mount
- Pros: It raises the bottom shelf product to eye level, which is prime "buy level" for customers. It is also much easier for technicians to service without a ladder.
- Cons: The compressor is near the floor, meaning it acts like a vacuum for dust, dirt, and flour. It requires more frequent cleaning of the coils.
Top Mount
- Pros: The compressor stays cleaner because it is away from the floor dust. Heat rises away from the cabinet, keeping the box cooler.
- Cons: Top shelves may be harder for short customers to reach. Servicing the unit requires a ladder.
Lighting: The Silent Salesperson
Standard fluorescent lighting is fading away. LED Lighting is the new standard for merchandising.
- Vibrant Color: LEDs have a higher Color Rendering Index (CRI), making red coke cans and green salads pop.
- Cooler Operation: LEDs emit almost no heat, unlike fluorescents which add heat load to the box.
- Vertical vs. Horizontal: Look for units with Vertical LED strips down the door frames. This eliminates dark spots on lower shelves that horizontal top-lighting can create.
Shelving & Organization
- Gravity Feed: Angled shelves that slide the next product forward automatically (common in convenience store drink coolers).
- Flat Shelves: Better for bulky items like cakes or deli platters.
- Adjustability: Ensure shelves can be raised/lowered to fit your specific packaging height without wasted vertical space.
Installation & Maintenance
Clearance & Airflow ("Breathing Room")
Merchandisers are heat exchange machines. They suck in cool room air and blow out hot exhaust.
- The Golden Rule: You typically need 2-3 inches of clearance on the back and sides (some front-breathing models can be built-in).
- Failure Consequence: Pushing a unit flush against a wall chokes the compressor. It will run hot, double your electric bill, and eventually seize up, voiding your warranty.
Cleaning the Condenser
- Frequency: Monthly.
- The Task: Dust acts as a sweater on your condenser coil. Use a stiff bristle brush or a vacuum to remove the "bunny" of gray dust that accumulates.
- Why: A dirty coil is the #1 cause of service calls for "unit not cooling."
Loading & Air Curtains
- The Load Line: Never stack product above the "Load Line" marker inside the case.
- Blocking Vents: In open air merchandisers, do not push product over the return air vents at the bottom front. This disrupts the air curtain, causing the case to sweat and the food to spoil.
Frequently Asked Questions
Can I use a standard beverage cooler for flowers?
No. A beverage cooler strips moisture out of the air and blows cold wind directly on the product. This will turn fresh flowers brown and brittle in less than 24 hours. A dedicated Floral Merchandiser uses low-velocity, high-humidity cooling to preserve blooms.
What is the difference between a dipping cabinet and a chest freezer?
A dipping cabinet is designed for serving. It raises the tubs to a comfortable scooping height and often has a glass sneeze guard/viewing window. A chest freezer is deep storage where tubs sit at the bottom; good for backstock, but terrible for service.
Are open air merchandisers efficient?
They are less energy-efficient than glass door units because some cold air inevitably escapes. However, the trade-off is higher sales volume. The removable barrier encourages impulse buys ("grab, pay, leave"), which often outweighs the extra electricity cost in high-traffic zones.
Can I put food in a glass door beverage cooler?
Check the rating. Some strictly "Beverage Coolers" are virtually identical to food refrigerators but may not be NSF-7 certified for "Time/Temperature Control for Safety" (TCS) foods like milk or sandwiches. Always look for the NSF/ANSI 7 certification if you plan to store open food or dairy.
What is a "convenience store merchandiser"?
This typically refers to a robust glass-door cooler (often 2 or 3 doors wide) with bright LED lighting, self-closing doors, and deep shelving designed for high-volume drink stocking (soda, beer, energy drinks).
Why is my open air cooler sweating?
Sweating usually means the air curtain has been disrupted. Check for three things: 1) Is an HVAC vent blowing warm air directly into the case? 2) Is product stacked over the return air vent? 3) Is the ambient room humidity too high (over 55-60%)?
Do wine refrigerators get cold enough for beer?
Often, no. Wine fridges are designed to run warmer (45°F - 65°F) for vintage preservation. Beer coolers need to get down to 33°F - 38°F. While dual-zone units exist, a standard single-zone red wine cooler will serve warm beer.
How loud are commercial merchandisers?
Commercial units have powerful compressors and are louder than residential fridges, typically ranging from 50 to 70 decibels. If placement is in a quiet area (like a library café or small floral shop), look for units with bottom-mounted compressors or specific "quiet operation" ratings.
Can I install a floral cooler myself?
Smaller, self-contained units simply plug into a standard outlet (though check the voltage/amperage). However, large walk-in display coolers require professional installation to ensure proper refrigeration line connections and drainage.
How long do merchandising refrigerators last?
With proper maintenance (especially cleaning the condenser coil monthly), a commercial merchandiser typically lasts 7-12 years. Neglecting maintenance can cut this lifespan in half.
