The Realmann SDO-N European-Style Commercial Island Display Freezer Series is designed for organized frozen food merchandising in supermarkets, grocery chains, convenience stores, and retail food outlets. Combining a horizontal cabinet structure with curved sliding glass lids, the series provides customer-facing frozen product display space in a distinctive European-style cabinet design.

Available in four models—SDO-558N, SDO-658N, SDO-758N, and SDO-858N—the range offers usable capacities from 329L to 727L and specified display areas from 0.87 m² to 1.98 m².

The cabinet features left-right sliding curved tempered glass lids with a coated glass surface intended to reduce condensation and maintain clear merchandise visibility. Aluminum alloy edging surrounds the glass opening, providing a practical finished structure for frequent retail access.

The refrigeration system uses R290 refrigerant, Donper or GMCC compressor options, and direct cooling technology. The freezer is specified for an operating temperature range of −18°C to −22°C, supporting frozen food storage and merchandising when the actual cabinet conditions meet the products’ requirements.

A key construction feature is the integrally foamed insulated cabinet, incorporating a thickened insulation layer and fine-cell foaming technology. This design helps limit heat transfer through the cabinet walls and supports the refrigeration system’s thermal requirements.

Inside the freezer, a pre-coated interior lining provides a practical surface for routine cleaning. Depending on the model, five to eight storage baskets are supplied for organizing packaged frozen products.

The cabinet incorporates drainage provisions at both the upper rim and interior compartment to help manage collected water during cleaning and maintenance. An anti-rodent protective design around the machinery compartment provides an additional consideration for commercial installations.

A full-length bottom base and enlarged resin casters support cabinet positioning and help reduce damage associated with handling or movement.

Unlike display freezers that rely on illuminated interiors, the SDO-N Series is specified without standard interior lighting, making it important for buyers to evaluate the store’s ambient lighting when planning product presentation.

As a commercial island freezer manufacturer, Realmann supports OEM/ODM cooperation and wholesale supply for supermarkets, frozen food distributors, and commercial refrigeration project buyers.

Key Features & Benefits

1. European-Style Cabinet for Supermarket Merchandising

The SDO-N Series features a European-style horizontal freezer cabinet designed for organized customer-facing frozen food displays.

Its clean cabinet profile and curved glass top provide a merchandising format suitable for supermarket freezer islands and grocery retail installations.

The four model sizes allow retailers to choose equipment according to floor space and product assortment.

2. Curved Tempered Glass with Left-Right Sliding Access

The freezer uses curved tempered glass lids that slide horizontally to the left and right.

This configuration allows customers to browse frozen products from above and access merchandise without lifting a hinged lid.

The glass incorporates a surface coating intended to help reduce condensation, supporting clearer product visibility under suitable operating conditions.

3. R290 Refrigeration for Commercial Frozen Storage

The refrigeration system uses R290 refrigerant, a hydrocarbon with a low global warming potential.

R290 is flammable and must be used in appropriately designed refrigeration systems with suitable safety provisions.

The SDO-N Series operates with direct cooling and is specified for temperatures from −18°C to −22°C.

4. Integrated Foamed Cabinet Construction

The cabinet incorporates integrated foaming technology, creating an insulated structure around the frozen storage compartment.

The product design also specifies a thickened insulation layer and fine-cell foam structure.

These features help reduce heat transfer, although the exact insulation thickness and energy consumption have not been provided.

5. Four Capacity Options from 329L to 727L

The series provides four usable capacity configurations:

The smaller SDO-558N and SDO-658N models provide compact freezer options, while the wider SDO-758N and SDO-858N accommodate larger frozen product assortments.

6. Coated Tempered Glass for Clear Product Viewing

The coated glass construction is designed to help reduce visible condensation on the freezer lid.

This is useful in commercial environments where humidity and temperature differences can lead to moisture formation on refrigerated glass.

Actual anti-condensation performance depends on ambient conditions, glass construction, and operating temperatures.

7. Aluminum Alloy Rim Protection

Aluminum alloy edging surrounds the upper cabinet opening and glass lid assembly.

The metal rim provides a practical finishing detail and supports the sliding glass structure during normal retail operation.

8. Dual Drainage Design

The SDO-N Series includes drainage provisions at the cabinet rim and inside the freezer compartment.

This design supports water management during cleaning and defrosting.

Because the freezer uses direct cooling, periodic manual defrosting may be required depending on frost accumulation.

9. Anti-Rodent Machinery Compartment Design

The machinery compartment incorporates anti-rodent protective features intended to reduce access by rodents.

This supports equipment protection in commercial installations, although it does not replace appropriate pest-control measures or sanitation procedures.

10. Pre-Coated Interior for Routine Cleaning

The freezer interior features a pre-coated lining designed for regular cleaning and maintenance.

The smooth, coated surface provides a practical storage environment for appropriately packaged frozen merchandise.

The exact lining substrate should be confirmed where a particular material specification is required.

11. Reinforced Storage Baskets

The freezer includes multiple storage baskets for product organization.

Basket quantities vary by model, allowing retailers to separate frozen foods by category, packaging size, or brand.

12. Full-Length Base and Enlarged Resin Casters

The cabinet uses an integrated bottom base and enlarged resin casters.

This arrangement supports cabinet mobility and helps reduce handling-related damage during positioning.

The freezer should be moved and installed according to suitable commercial equipment handling procedures.
