Hydra-Kool HK-GDT-80-S 78 In. Dual Temperature Triple-Door Glass Merchandiser, Self-Contained, Vertical LED, R290

SKUHK-GDT-80-S BrandHydra-Kool

The Hydra-Kool HK-GDT-80-S Glass Door Merchandiser Refrigerator

The Hydra-Kool HK-GDT-80-S is a 78-inch triple-door glass merchandiser that runs as either a freezer or a refrigerator, switchable between -1°F to -6°F and 33°F to 39°F. If your merchandising mix shifts between frozen and refrigerated through the season, or you need a single case that pulls double duty in a smaller store footprint, this unit handles both without a technician visit or any hardware changes. You get 30.6 cu. ft. of net volume, 30 sq. ft. of total display area, and 40.6 sq. ft. of refrigerated shelf area spread across four levels of adjustable shelving behind three self-closing hinged doors with double tempered glass.

Electronic Temperature Control with Programmable Automatic Defrost

An electronic temperature controller gives you direct access to set the operating range for either freezer or refrigerator mode. Switching between modes is a controls adjustment, not a mechanical reconfiguration. Programmable automatic defrosting runs on a schedule you set, so ice buildup never reaches the point where it blocks airflow or reduces visibility. The electric evaporation system handles defrost water automatically, eliminating the drain pan checks and manual draining that eat into staff time on older units. Between the controller, the defrost programming, and the evaporation system, day-to-day temperature management requires minimal operator intervention.

Four-Level Adjustable Shelving with Vertical LED Lighting and Double Tempered Glass Doors

Four levels of removable, adjustable, and tiltable shelves let you configure the interior for anything from tall beverage bottles on fewer levels to shallow dairy and deli trays stacked across all four. The shelves tilt forward for gravity-feed presentation, which keeps product faced toward the customer without constant restocking. Vertical LED lighting runs the full height of the cabinet on both sides, so every shelf level gets even illumination without the hot spots and shadowed corners you see with overhead-only fluorescent setups. LEDs also generate less heat inside the cabinet, which means the compressor works less to hold temperature. Three self-closing hinged doors with double tempered glass reduce fogging and thermal loss every time a customer opens and walks away without closing the door fully.

Ventilated Self-Contained Refrigeration with R290 and PUR/H2O Insulation

The refrigeration system is self-contained and ventilated, so it installs as a plug-in unit with no remote condenser or rooftop equipment to plan for. R290 refrigerant carries a GWP of 3, which puts it well ahead of older HFC refrigerants from a regulatory and environmental standpoint. PUR/H2O (polyurethane water-blown) insulation lines the cabinet walls, providing high thermal resistance without ozone-depleting blowing agents. The unit is rated for ambient conditions up to 25°C (77°F) at 60% relative humidity (climate class L1/M1). Standard voltage is 230V/1Ph/50Hz, with optional configurations available at 115V-60Hz, 120V-60Hz, and 220V-60Hz. Nominal power draw is 2,906W at 14.23A. The exterior features a front decoration in painted plate with a RAL finish and a display area in skinplate, with solid sides and adjustable feet standard. Castors with brakes are available as an option.

    About Glass Door Merchandiser Refrigerators

    A glass door merchandiser refrigerator is an upright commercial cooler with glass doors and interior LED lighting. It holds beverages, dairy, prepared foods, and grab-and-go items at safe service temperatures while merchandising the product to customers from behind glass. Convenience stores, supermarkets, beverage retailers, hotel breakfast counters, hospital cafeterias, and grocery prepared-food sections use them at customer eye level. Common product lines include bottled drinks, canned beverages, energy drinks, milk, juice, packaged sandwiches, prepared salads, and grab-and-go meals. The same equipment is also called a commercial glass door refrigerator, glass door display refrigerator, glass door cooler, or commercial beverage refrigerator.

    The right glass door merchandiser refrigerator depends on three things: floor footprint, the product line, and how many doors the venue needs for browsing. Catalog widths run from 15 to 98 inches with capacities from 6.5 to 71 cubic feet. Single-door units suit small convenience stores and offices. Double-door units cover most mid-volume retail. Triple and quad-door units serve high-volume supermarkets, large convenience stores, and beverage retailers. Swing doors give full-width access; sliding doors save aisle clearance in tight spaces. Common configurations, buying guidance, and frequent buyer questions follow below.

    Common Types and Configurations

    • Single glass door merchandiser refrigerator: One swing or sliding glass door. Catalog units run 15 to 30 inches wide with 6.5 to 19.2 cubic feet of capacity. Suited to small convenience stores, gas stations, offices, and specialty grocers.
    • Double glass door merchandiser refrigerator: Two swing or sliding glass doors side-by-side. Catalog units run 38 to 54 inches wide with 26 to 45 cubic feet. Most common configuration for mid-volume convenience stores, supermarkets, and beverage retailers.
    • Triple glass door merchandiser refrigerator: Three swing or sliding glass doors. Catalog units run 59 to 78 inches wide with 42 to 71 cubic feet. Suited to high-volume convenience stores and supermarket beverage aisles.
    • Four glass door merchandiser refrigerator: Four glass doors. Catalog 98-inch unit for the largest supermarket beverage and prepared-food sections.
    • Slim line merchandiser: Narrow profile at 15 inches wide with 6.5 cubic feet for tight retail layouts where a standard merchandiser would not fit.
    • Wide merchandiser: Extra-wide format at 93 inches for high-volume beverage retailers needing maximum single-cabinet capacity.
    • Energy Star series: Select catalog lines are Energy Star certified for reduced operating cost in 24/7 retail environments.
    • Display refrigerator with lightbox: Top backlit signage panel above the glass door for branding and category callouts. Lifts impulse purchase in high-traffic retail.
    • Swing vs sliding doors: Swing doors give full-width interior access for fast restocking. Sliding doors save aisle clearance in tight retail layouts where a swing door arc would block customer flow.

    What to Look at Before You Buy

    • Floor footprint and door count: Catalog widths run 15 to 98 inches. Match door count to merchandised category breadth: 1 door for a focused beverage or grab-and-go program, 2 doors for mid-range retail, 3 to 4 doors for full supermarket beverage aisle.
    • Product line: Bottled and canned drinks suit standard wire shelving. Milk and dairy fit shelved configurations with sturdy adjustable shelves. Packaged sandwiches, salads, and grab-and-go meals need shallower shelves and stronger lighting. Tall energy drink and sports drink merchandising fits the slim-line format.
    • Swing vs sliding doors: Swing doors suit operators that prioritize fast restocking access. Sliding doors fit tight retail layouts and avoid blocking customer aisles when a door is open. Sliding glass doors are also standard on back-bar applications.
    • Capacity: Catalog runs 6.5 to 71 cubic feet. Small operations need 6.5 to 19 cubic feet (single door). Mid-volume retailers need 19 to 45 cubic feet (double door). High-volume retailers need 42 to 71 cubic feet (triple or quad door).
    • Refrigerant and energy: R290 hydrocarbon refrigerant has lower GWP than legacy refrigerants. Energy Star certification on select catalog lines reduces operating cost in 24/7 retail environments. Confirm a dedicated 115V or 208V circuit depending on the model.
    • Finish: Stainless steel suits modern retail and supermarkets. Black and white suit convenience stores and gas stations where the case sits against painted walls or branded fixtures.
    • Lightbox and branding: A top lightbox panel lifts impulse purchase by drawing customer attention. Available on select catalog units. Worth the upgrade in front-of-store merchandising positions.
    • Cleaning access: Removable shelves, accessible interior, and easy glass cleaning matter for daily sanitation. Confirm shelf adjustability for product reset between merchandising programs.

    Frequently Asked Questions

    What is a glass door merchandiser refrigerator used for?

    A glass door merchandiser refrigerator is a commercial upright refrigerator with glass doors and interior LED lighting. It holds beverages, dairy, and prepared foods at safe service temperatures while merchandising the product to customers from behind glass. Convenience stores use them for bottled and canned drinks, energy drinks, sports drinks, milk, and packaged grab-and-go items at the front of the store. Supermarkets use them for the beverage aisle, milk wall, and prepared-food sections. Hotel breakfast counters use them for juice, milk, and yogurt at the buffet line. Hospital cafeterias and corporate offices use them for grab-and-go sandwiches and salads.

    What is the difference between a glass door merchandiser refrigerator and a reach-in refrigerator?

    A glass door merchandiser refrigerator has glass doors and interior LED lighting designed to display product to customers in retail and grocery environments. It sits on the customer-facing side of the store. A reach-in refrigerator has solid doors with no display function. It sits in the back of house for kitchen storage or in the line for cook access. The two formats use the same underlying commercial refrigeration but optimize for different jobs: merchandising versus storage. Both hold product at safe service temperatures, but the merchandiser is built for visibility while the reach-in is built for capacity and energy efficiency behind closed doors.

    What size glass door merchandiser refrigerator do I need (1, 2, 3, or 4 door)?

    Match door count to merchandised category breadth and floor footprint. Small convenience stores, offices, and specialty grocers with a focused program suit a single-door unit at 15 to 30 inches wide with 6.5 to 19 cubic feet. Mid-volume convenience stores, supermarkets, and beverage retailers need a double-door unit at 38 to 54 inches with 26 to 45 cubic feet. High-volume supermarkets and large convenience stores need a triple-door unit at 59 to 78 inches with 42 to 71 cubic feet. Full supermarket beverage aisles need a four-door unit at 98 inches. The slim-line single-door format fits tight retail layouts where a standard merchandiser would not fit.
