The Realmann Commercial High Front Glass Seafood Display Freezer Series is developed for frozen seafood merchandising in supermarkets, seafood markets, grocery chains, and commercial frozen food retail environments. Featuring an enlarged front viewing window and double-layer sliding glass lids, the series provides enhanced product visibility from both the front and top of the cabinet.

Available in three models—SDG-2000N, SDG-2500N, and SD-26000N—the series offers 687L, 851L, and 910L usable capacities, providing large horizontal display configurations for retail businesses requiring substantial refrigerated merchandising space.

Unlike conventional chest freezers that primarily allow customers to view products from above, this series features an extra-high front viewing window made from Low-E coated glass. The enlarged front glazing helps customers see displayed merchandise from the aisle, improving the presentation of packaged seafood and suitable refrigerated food products.

The cabinet also incorporates double-layer sliding glass lids at the top, providing convenient merchandise access without the outward clearance required by hinged doors.

An aluminum alloy rim and chrome-plated corner components provide a finished structure around the glass assembly. The exterior uses white pre-coated steel, while the interior features pre-coated aluminum panels for routine cleaning and commercial storage.

The refrigeration system uses R290 refrigerant, Donper or CMCC compressor configurations, and static cooling technology. The specified temperature adjustment range is 0°C to −18°C, allowing buyers to select settings appropriate to the intended application, subject to verified cabinet performance.

Inside the cabinet, a flat-bottom structure provides a practical surface for product placement. Internal anti-bulging reinforcement bars help resist outward cabinet deformation, while four to six storage baskets provide convenient product organization depending on the selected model.

The series supports digital or mechanical temperature controller configurations according to the supplied specifications.

As a commercial refrigeration manufacturer, Realmann offers OEM/ODM cooperation for supermarket equipment distributors, seafood retailers, and international commercial refrigeration buyers.

Key Features & Benefits

1. Extra-High Front Viewing Window

The defining feature of this series is its enlarged front viewing window.

Unlike standard horizontal freezers with primarily top-down product visibility, the high front glass allows customers to see merchandise from the front of the cabinet.

This is particularly useful for customer-facing seafood merchandising where product presentation and visual accessibility are important.

2. Low-E Coated Glass for Display Visibility

The front viewing window uses Low-E coated glass.

The Low-E coating helps reduce radiant heat transfer through the glazing, supporting the thermal design of the display cabinet.

The transparent construction maintains product visibility, while actual condensation performance depends on ambient humidity and glass temperature.

3. Double-Layer Sliding Glass Lids

The cabinet features double-layer sliding glass lids at the top.

The glass panels allow customers to browse merchandise from above and access products through a sliding opening.

The double-layer construction provides an insulated barrier between the display compartment and surrounding retail environment.

4. Large Storage Capacities from 687L to 910L

The series provides three usable capacity configurations:

These capacities support large-scale horizontal merchandise presentation and allow retailers to select equipment according to available display space.

5. Adjustable Temperature from 0°C to −18°C

The series is specified with a temperature adjustment range from 0°C to −18°C.

This enables buyers to evaluate the cabinet for suitable chilled or frozen products, depending on the required storage temperature and verified operating performance.

The adjustable range does not establish independently controlled temperature compartments.

6. R290 Static Cooling

The refrigeration system uses R290 refrigerant and direct cooling technology.

Static refrigeration removes heat through the cabinet’s cooling surfaces without using an internal fan to circulate air.

R290 has a low global warming potential but is flammable, requiring appropriate equipment design, installation, and service procedures.

7. Donper or CMCC Compressor Options

The supplied specification lists Donper and CMCC compressor configurations.

These are alternative compressor options, and the selected brand should be confirmed during procurement.

The exact compressor model and quantity have not been supplied.

8. Aluminum Alloy Rim with Chrome-Plated Corners

The cabinet incorporates aluminum alloy edging and chrome-plated corner components around the glass opening.

These components provide a finished commercial appearance and support the cabinet’s glass lid assembly.

9. Pre-Coated Steel Exterior and Aluminum Interior

The exterior uses white pre-coated steel panels, while the interior features pre-coated aluminum.

The coated surfaces provide practical finishes for commercial food display and facilitate routine cleaning.

10. Flat-Bottom Interior Structure

The cabinet includes a flat-bottom storage compartment.

This provides a level surface for arranging appropriate packaged seafood products, cartons, and storage baskets.

The final arrangement should remain within the manufacturer’s specified loading limits.

11. Internal Anti-Bulging Reinforcement Bars

Internal support bars help resist outward deformation of the horizontal cabinet walls.

These bars form part of the structural construction and should remain installed according to the manufacturer’s instructions.

12. Digital or Mechanical Temperature Control

The technical sheet lists digital and mechanical temperature controller options.

Buyers can discuss their preferred control interface according to installation and operational requirements.

The actual temperature settings and controller functions depend on the selected configuration.

Technical Specifications

SDG-2000N / SDG-2500N / SD-26000N Comparison

*The supplied image lists the SD-26000N dimensions as 2500 × 1200 × 8600 mm. The 8600 mm height appears inconsistent with the product category and the other models. The model number and height should be verified before publication. The table preserves the original values rather than assuming a correction.

Additional Product Specifications

Commercial Applications

1. Supermarket Seafood Display Sections

The series provides a horizontal seafood merchandising solution for supermarkets requiring greater product visibility.

The high front viewing window allows shoppers to see products from the aisle, while the sliding glass lids provide access from above.

2. Frozen Fish and Seafood Retail

The cabinets can be used for appropriately packaged frozen seafood where the required storage temperature is maintained.

Products requiring continuous storage at −18°C must be held under conditions that meet that requirement.

3. Fresh and Chilled Seafood Merchandising

The adjustable temperature range includes settings near 0°C, allowing the cabinet to be evaluated for selected chilled seafood applications.

However, actual product temperatures, sanitation requirements, and storage methods must be verified before using the equipment for fresh seafood.

4. Frozen Food Promotional Displays

The high front window can support product visibility in supermarket promotional areas.

Retailers can organize packaged frozen foods in the available baskets and display compartment.

5. Commercial Seafood Markets

Specialty seafood retailers may use these cabinets for suitable packaged fish, shellfish, and other temperature-compatible products.

The larger capacity options support broader product assortments than compact seafood display cabinets.

6. Seafood Distribution and Retail Equipment Projects

Seafood distributors and equipment importers can consider the series for retail placement projects requiring horizontal refrigerated displays.

The three cabinet configurations offer different usable capacities and installation footprints.
