SD-420F / SD-920F / SD-1450F Flat Top Commercial Glass Door Display Freezer

The Realmann Flat Top Commercial Glass Door Display Freezer is designed for frozen food merchandising in supermarkets, grocery stores, convenience outlets, and commercial retail environments. Available in three cabinet widths, this series combines a flat-top structure with customer-facing frozen product displays and practical maintenance features.

Designed to operate within a specified temperature range of −15°C to −22°C, the SD-420F, SD-920F, and SD-1450F models use fan-forced cooling to circulate cold air throughout the cabinet. The refrigeration system incorporates R290 refrigerant, Cubigel compressors, digital CAREL temperature controls, and an enlarged copper-aluminum finned evaporator with a manufacturer-specified 30% design allowance.

A key feature of this series is its triple-layer electrically heated Low-E tempered glass doors. The insulated glazing helps limit heat transfer, while electric heating reduces the risk of condensation and fogging on the glass surface. This enables customers to view frozen merchandise without opening the cabinet.

The freezer interior features pre-coated aluminum panels, four adjustable shelf levels, and corrosion-resistant aluminum alloy shelf supports. Vertical LED lighting installed along both sides improves visibility of packaged frozen foods, frozen vegetables, ready meals, and other temperature-compatible products.

Self-closing hinged glass doors help reduce the likelihood of prolonged door openings, while the integrated door handle design provides convenient access without prominent external handles.

The cabinet also includes a self-evaporating condensate system and enlarged swivel casters for easier positioning and routine maintenance.

As a commercial refrigeration OEM/ODM manufacturer, Realmann provides equipment configuration and customization services for freezer distributors, retail equipment importers, and supermarket refrigeration projects.

Key Features & Benefits

1. Flat-Top Cabinet with Integrated Door Handles

The freezer features a streamlined flat-top cabinet design and integrated door handles.

Compared with conventional protruding handle structures, the integrated design provides a cleaner front appearance and helps reduce unnecessary projections from the cabinet.

This configuration is well suited to supermarket freezer aisles and coordinated retail installations where equipment appearance and access clearance are important.

2. Triple-Layer Electrically Heated Low-E Glass

The freezer uses triple-layer insulated tempered glass doors with Low-E coating and integrated electric heating.

The insulated construction helps reduce heat transfer through the doors, while electric heating helps control glass condensation and maintain clearer product visibility.

This glazing design is particularly relevant to frozen food display cabinets operating at substantially lower temperatures than the surrounding environment.

3. Fan-Forced Cooling from −15°C to −22°C

The SD Series is designed for frozen merchandise display within a specified cabinet temperature range of −15°C to −22°C.

Fan-forced refrigeration circulates cold air through the cabinet, supporting temperature distribution across multiple product shelves.

For products requiring storage at or below −18°C, appropriate setpoints and actual product temperatures must be verified.

4. Three Cabinet Sizes for Frozen Merchandising

The series includes three cabinet widths to accommodate different retail floor plans:

• SD-420F: 630 mm wide

• SD-920F: 1230 mm wide

• SD-1450F: 1850 mm wide

These configurations allow retailers to select compact or wider display cabinets depending on available installation space and merchandising volume.

5. R290 Refrigeration with Cubigel Compressors

The refrigeration system uses R290 refrigerant and Cubigel compressors.

The SD-420F is specified with one compressor, while the SD-920F and SD-1450F models use two compressors.

R290 has a low global warming potential and is suitable for appropriately designed refrigeration equipment. Because it is flammable, installation and servicing must follow applicable safety requirements.

6. Enlarged Copper-Aluminum Finned Evaporator

The refrigerator incorporates an enlarged copper-aluminum finned evaporator with a manufacturer-specified 30% additional design allowance.

The evaporator provides heat-exchange surfaces for the refrigeration system, while the additional allowance represents a design margin.

Actual freezing performance depends on the complete refrigeration configuration, ambient temperature, product loading, and operating conditions.

7. Four Adjustable Shelf Levels

Each model includes four shelf levels that can be adjusted to accommodate different packaging heights.

Retailers can organize boxed frozen foods, packaged vegetables, frozen snacks, and other suitable products according to their display requirements.

The aluminum alloy shelf supports resist corrosion and facilitate routine shelf adjustment and cleaning.

8. Vertical LED Lighting for Product Presentation

Vertical LED lighting is installed along both sides of the freezer interior.

This arrangement helps illuminate merchandise across multiple shelves, improving visibility and allowing customers to identify frozen products through the glass doors.

9. Self-Closing Hinged Glass Doors

The self-closing door mechanism helps return the doors to their closed position after customer access.

This limits the likelihood of doors being accidentally left open, reducing avoidable warm-air infiltration during normal retail operation.

10. Self-Evaporating Condensate System and Easy Mobility

The integrated self-evaporating condensate system reduces routine manual water disposal requirements under intended operating conditions.

Enlarged swivel casters facilitate cabinet positioning and cleaning access.

Optional door and frame configurations and bottom wheel arrangements are available for project discussion.

Frequently Asked Questions (FAQ)

Q1: What is a flat top commercial display freezer?

A flat top commercial display freezer is an upright low-temperature cabinet with a flat upper profile and transparent glass doors.

It is designed to store and display frozen merchandise while allowing customers to view products without opening the freezer.

Q2: What temperature range does this freezer support?

The SD-420F, SD-920F, and SD-1450F have a specified operating temperature range of −15°C to −22°C.

The correct operating setpoint depends on the frozen products being stored and their applicable storage requirements.

Q3: What are the benefits of triple-layer heated Low-E glass?

Triple-layer insulated glazing helps reduce heat transfer through the freezer doors.

The Low-E coating limits radiant heat transfer, while electric heating helps reduce condensation and fogging on the glass surface.

Together, these features support clearer product visibility in low-temperature merchandising environments.

Q4: What is the difference between the SD-420F, SD-920F and SD-1450F?

The main differences are cabinet width, compressor configuration, and specified usable capacity.

The SD-420F measures 630 mm in width and uses one Cubigel compressor, while the SD-920F and SD-1450F measure 1230 mm and 1850 mm respectively and use two compressors.

Buyers should confirm final usable capacity figures before ordering.
