The Realmann Commercial Flat Glass Sliding Lid Display Freezer Series is designed for horizontal frozen food merchandising in supermarkets, grocery stores, frozen food outlets, and commercial retail environments. Covering nine models across the LD, SDG, and SCD product ranges, the series offers different cabinet dimensions, storage capacities, and temperature configurations for retail refrigeration projects.
The LD Series includes four models with usable capacities from 236L to 528L, while the SDG Series provides larger refrigerated display cabinets with capacities from 588L to 878L. Both series use a direct cooling system and are specified for storage temperatures of −15°C or below.
The SCD-316 and SCD-386 models offer a different specified temperature range of −6°C to −12°C, making them suitable for selected frozen dessert and specialty food applications where the required storage temperature is compatible with the equipment.
A defining feature of these cabinets is the double-layer flat sliding glass lid design, which allows customers to view merchandise from above and access products through a sliding opening. The flat glass profile supports a streamlined presentation in supermarket frozen food areas.
The cabinet features a white pre-coated steel exterior and embossed aluminum interior. Removable chrome-plated corner trims provide a practical finishing detail, while the flat-bottom interior supports flexible placement of packaged frozen products and storage baskets.
To reinforce the cabinet structure, the series incorporates internal anti-bulging support bars intended to resist cabinet wall deformation. Enlarged swivel casters facilitate positioning during installation, cleaning, and retail layout changes.
The refrigeration system uses LG compressors, R134a refrigerant, and mechanical temperature controllers, according to the supplied technical specifications.
As a commercial refrigeration manufacturer, Realmann supports OEM/ODM cooperation and wholesale inquiries for supermarket equipment distributors, frozen food retailers, and commercial refrigeration procurement projects.
Key Features & Benefits
1. Double-Layer Flat Sliding Glass Lids
The cabinet features double-layer flat sliding glass lids designed for horizontal frozen food merchandising.
The transparent top enables customers to browse products before opening the freezer, while the sliding mechanism provides convenient access without requiring the clearance of a hinged lid.
The flat glass profile offers a clean and consistent appearance for supermarket freezer installations.
2. Three Product Ranges for Different Storage Requirements
The series includes three groups with different storage capacities and operating temperatures.
| Series | Models | Usable Capacity | Specified Temperature |
|---|---|---|---|
| LD | LD-236 / 358 / 426 / 528 | 236–528 L | ≤ −15°C |
| SDG | SDG-2.0 / 2.2 / 2.5 | 588–878 L | ≤ −15°C |
| SCD | SCD-316 / 386 | 316–386 L | −6°C to −12°C |
This range allows buyers to select cabinets based on product storage requirements, capacity, and available retail floor space.
3. Removable Chrome-Plated Corner Trims
The cabinet incorporates removable chrome-plated corner components.
These trims provide a finished appearance at the cabinet corners and can be removed for appropriate maintenance or replacement.
This construction detail helps distinguish the series from standard chest freezers with fixed plastic corner structures.
4. White Pre-Coated Steel Exterior
The external cabinet uses white pre-coated steel panels.
This provides a clean commercial appearance suitable for supermarket and grocery store installations.
The coated surface also facilitates routine exterior cleaning according to the manufacturer’s maintenance instructions.
5. Embossed Aluminum Interior
The freezer interior features embossed aluminum panels.
The textured aluminum lining provides a practical surface for commercial frozen food storage and cleaning.
This material combination supports a durable cabinet structure for appropriately packaged merchandise.
6. Flat-Bottom Interior for Flexible Product Placement
The flat-bottom structure provides a level interior storage surface.
This allows retailers to arrange packaged frozen foods, cartons, or storage baskets according to product dimensions and available cabinet space.
The final loading arrangement should remain within the manufacturer’s specified capacity and loading limits.
7. Internal Anti-Bulging Reinforcement Bars
The cabinet includes internal reinforcement bars designed to help resist bulging or deformation of the cabinet walls.
These components support structural stability in the horizontal cabinet design.
They should remain installed according to the manufacturer’s instructions and should not be removed without technical approval.
8. LG Compressor with Direct Cooling
All nine models are specified with LG compressors and a direct cooling system.
Direct cooling transfers heat through the cabinet’s refrigeration surfaces without requiring a fan to circulate air within the storage compartment.
Periodic manual defrosting may be required depending on frost accumulation and operating conditions.
9. Mechanical Temperature Control
A mechanical temperature controller provides a straightforward interface for adjusting freezer operating settings.
The appropriate setting depends on the selected model’s specified temperature range and the requirements of the products being stored.
10. Enlarged Swivel Casters
The cabinet includes enlarged swivel casters to facilitate positioning during installation and maintenance.
This feature is useful for supermarket equipment arrangements where freezers may need to be repositioned for cleaning or store layout adjustments.

Commercial Applications
1. Supermarket Frozen Food Merchandising
The LD and SDG models provide horizontal display space for supermarkets and grocery stores.
Their transparent sliding glass lids allow shoppers to view products while helping separate the frozen compartment from the surrounding retail environment.
Adjustable product arrangements and storage baskets can be used for packaged frozen merchandise.
2. Frozen Food Island Displays
The larger SDG-2.0, SDG-2.2, and SDG-2.5 models provide wider cabinet configurations suitable for supermarket island-style freezer arrangements.
The flat glass design creates a streamlined appearance, while enlarged swivel casters support equipment positioning during installation.
3. Packaged Frozen Vegetable and Prepared Food Displays
The LD and SDG models can be considered for packaged frozen vegetables, prepared meals, and other merchandise whose required storage temperature is compatible with the cabinet’s verified operating performance.
Products requiring storage at −18°C or below should not be assigned to these cabinets solely on the basis of their stated ≤ −15°C specification.
4. Selected Frozen Dessert Displays
The SCD-316 and SCD-386 offer a specified range of −6°C to −12°C.
These models may be suitable for selected frozen dessert applications requiring a warmer serving or display temperature than conventional frozen food storage.
Suitability must be verified against the product manufacturer’s temperature requirements and applicable food safety standards.
5. Grocery and Specialty Food Retail
The range provides different cabinet widths, depths, and usable capacities for specialty food retailers.
Buyers can select a model based on available floor space, intended merchandise, and temperature requirements.

It is commonly used for customer-facing frozen product merchandising in suitable retail environments.
Q2: What is the difference between the LD, SDG, and SCD Series?
The primary differences are cabinet dimensions, usable capacities, and operating temperature ranges.
The LD Series offers 236L–528L, while the SDG Series provides larger 588L–878L configurations.
Both have a specified temperature of −15°C or below.
The SCD Series offers 316L and 386L models operating from −6°C to −12°C.
Q3: Are all models suitable for standard frozen food storage at −18°C?
Not necessarily.
The LD and SDG models are specified for ≤ −15°C, which does not guarantee that they can maintain −18°C under all intended conditions.
The SCD models operate at −6°C to −12°C and should not be used for products requiring −18°C storage without a separately verified configuration.
