The Realmann SDG-N Commercial Low-Profile Island Display Freezer Series is designed for frozen food merchandising in supermarkets, grocery stores, retail chains, and self-service frozen food sections. Available in four models—SDG-1500N, SDG-1800N, SDG-2000N, and SDG-2500N—the series provides usable capacities ranging from 232L to 529L while maintaining a consistent cabinet height of 880 mm.
A defining feature of the SDG-N Series is its low-profile horizontal cabinet design, allowing retailers to present frozen merchandise in a display format that can be incorporated into supermarket aisles and promotional freezer areas.
The freezer features coated tempered glass sliding lids with left-right opening access. This arrangement allows shoppers to view packaged frozen merchandise from above and retrieve products without lifting a hinged cover. Aluminum alloy edging provides a practical frame around the glass opening.
The refrigeration system uses R290 refrigerant with direct cooling technology, supporting a specified operating temperature range of −18°C to −22°C. Donper or GMCC compressor configurations are available, together with digital or mechanical temperature controller options.
The cabinet uses integrated foamed insulation with a thickened, fine-cell foam structure. This helps limit heat transfer through the cabinet walls and supports the freezer’s low-temperature operating requirements.
Inside the cabinet, a pre-coated lining provides a practical surface for routine cleaning. Four or six storage baskets are supplied depending on the model, helping retailers organize different frozen food categories.
For everyday operation, the freezer incorporates drainage provisions at the cabinet rim and inside the storage compartment. Anti-rodent protection around the machinery compartment helps reduce unwanted access to internal components.
A full-length bottom base and enlarged resin casters facilitate cabinet positioning and support handling in commercial retail environments.
The SDG-N Series is supplied without standard interior lighting, making external store lighting an important consideration when planning the merchandise display.
As an OEM/ODM commercial refrigeration manufacturer, Realmann supports wholesale and project-based inquiries from supermarket equipment distributors, frozen food retailers, and international refrigeration importers.
Key Features & Benefits
1. Low-Profile Horizontal Cabinet Design
The SDG-N Series is designed with a consistent cabinet height of 880 mm across all four models.
This provides a coordinated display profile for supermarket freezer layouts, allowing retailers to select different cabinet widths while maintaining a consistent equipment height.
The design is suitable for horizontal frozen food merchandising and customer self-service access.
2. Sliding Tempered Glass Lids with Coated Surface
The freezer incorporates sliding tempered glass lids designed for convenient product viewing and access.
The glass surface includes a coating intended to reduce condensation, helping maintain merchandise visibility under suitable ambient conditions.
The left-right sliding arrangement allows customers to open the glass panels without the outward clearance required by hinged lids.
3. R290 Direct Cooling from −18°C to −22°C
The refrigeration system uses R290 refrigerant and static cooling technology.
The specified operating range of −18°C to −22°C supports suitable frozen food merchandising when actual cabinet conditions meet the products’ storage requirements.
R290 has a low global warming potential but is flammable, requiring appropriately designed equipment and suitable servicing procedures.
4. Four Capacity Options from 232L to 529L
The series includes four cabinet configurations:
| Model | Usable Capacity | Display Area |
|---|---|---|
| SDG-1500N | 232 L | 0.87 m² |
| SDG-1800N | 284 L | 1.06 m² |
| SDG-2000N | 410 L | 1.54 m² |
| SDG-2500N | 529 L | 1.98 m² |
The range allows retailers to select storage volume and display area according to available floor space and merchandising requirements.
5. Integrated Fine-Cell Foamed Insulation
The cabinet incorporates an integrally foamed insulation structure.
The product description specifies a thickened foam layer and fine-cell foaming technology intended to limit heat transfer through the cabinet body.
The exact insulation thickness and thermal conductivity have not been provided, so energy performance should be evaluated using verified manufacturer data.
6. Aluminum Alloy Edging for Sliding Glass Assembly
Aluminum alloy trim surrounds the upper glass opening.
This provides a practical edge structure for the sliding lids and contributes to the cabinet’s commercial appearance.
The trim is suitable for routine cleaning and maintenance according to the manufacturer’s instructions.
7. Donper or GMCC Compressor Options
The supplied technical specifications list Donper and GMCC compressor configurations.
These brands are available as alternatives rather than simultaneous installations.

These features help manage collected water during cleaning and defrosting.
Because the refrigeration system uses static cooling, periodic manual defrosting may be necessary.
11. Anti-Rodent Machinery Compartment Protection
The machinery compartment includes protective features designed to limit rodent access.
This supports equipment protection in retail and storage environments but does not replace normal sanitation and pest-control measures.
12. Integrated Base with Enlarged Resin Casters
The freezer uses a full-length bottom base and enlarged resin casters.
This arrangement facilitates equipment movement during installation or cleaning and helps reduce handling-related damage.
