Commercial Flat Top Glass Door Display Freezer

The Realmann SD-FT Commercial Flat Top Glass Door Display Freezer Series is designed for organized frozen food merchandising in supermarkets, grocery chains, convenience stores, and frozen food retail outlets. Available in six models with usable capacities ranging from 448L to 1980L, the series combines a flat-top cabinet profile with low-temperature refrigeration and customer-facing product display.

Unlike conventional display refrigerators intended for chilled products, the SD-FT Series operates within a specified temperature range of −15°C to −20°C, making it suitable for frozen merchandise when the cabinet temperature meets the individual product’s storage requirements.

The freezer features triple-layer electrically heated Low-E tempered glass doors. The insulated glass assembly helps reduce heat transfer, while electric heating helps limit condensation and fogging on the glass surface. This allows customers to identify packaged frozen products without opening the freezer.

The fan-forced cooling system uses R290 refrigerant, Cubigel compressors, and digital CAREL temperature controls. An enlarged copper-aluminum finned evaporator incorporates a manufacturer-specified 30% design allowance to support the refrigeration system’s heat-exchange requirements.

Inside the cabinet, adjustable shelves with corrosion-resistant aluminum alloy supports provide flexible space for packaged frozen foods, frozen vegetables, desserts, and other suitable products. Vertical LED lighting along both interior sides improves visibility throughout the display compartment.

The self-closing hinged glass doors help reduce accidental prolonged openings, while the self-evaporating condensate system reduces the need for routine manual water disposal. Extended door handles and enlarged swivel casters further support convenient commercial operation.

As a commercial display freezer manufacturer, Realmann offers OEM/ODM cooperation for distributors, supermarket equipment buyers, and frozen food retail projects requiring different cabinet sizes and optional accessories.

Key Features & Benefits

1. Flat-Top Cabinet Design for Supermarket Freezer Layouts

The SD-FT Series features a flat-top cabinet profile designed for commercial refrigerated equipment arrangements.

Its streamlined upper cabinet structure provides a clean appearance for supermarket freezer sections and coordinated retail installations.

With cabinet widths of 685 mm, 1370 mm, and 2050 mm, the range offers different footprints to accommodate a variety of frozen merchandising layouts.

2. Triple-Layer Electrically Heated Low-E Tempered Glass

The insulated glass doors combine three layers of glazing, a Low-E coating, and electric heating.

The triple-layer structure helps limit heat transfer between the frozen interior and ambient retail environment. Electric heating helps reduce condensation and fogging, improving the visibility of displayed merchandise.

This construction is particularly relevant to low-temperature commercial freezers operating in environments where humidity and temperature differences can affect glass clarity.

3. −15°C to −20°C Frozen Product Display

The SD-FT Series provides a specified temperature range of −15°C to −20°C.

This low-temperature operation supports suitable frozen food merchandising, including packaged frozen vegetables, prepared meals, and selected frozen desserts.

Storage suitability must be determined according to the products’ required temperatures and applicable food safety requirements.

4. Six Usable Capacity Options from 448L to 1980L

The series includes six models for different retail capacities:

• SD-580FT: 448L

• SD-690FT: 546L

• SD-1180FT: 1055L

• SD-1390FT: 1266L

• SD-1780FT: 1577L

• SD-2090FT: 1980L

The smaller configurations suit limited retail floor space, while the larger models support extensive frozen food merchandising.

5. R290 Refrigeration with Cubigel Compressors

All models use R290 refrigerant and Cubigel compressors.

The SD-580FT through SD-1780FT are specified with one Cubigel compressor per model, while the SD-2090FT is equipped with two compressors.

R290 is a hydrocarbon refrigerant with a low global warming potential. Because it is flammable, the refrigeration system must be designed and serviced in accordance with applicable safety requirements.

6. Enlarged Copper-Aluminum Finned Evaporator

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

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

Actual freezing performance depends on the equipment configuration, installation conditions, product loading, and ambient temperature.

7. Digital CAREL Temperature Control

A digital CAREL temperature controller provides an interface for refrigeration setting adjustments and temperature monitoring according to the controller’s configuration.

This supports practical temperature management across different frozen food merchandising applications.

8. Adjustable Shelves with Aluminum Alloy Supports

The freezer includes adjustable shelves supported by aluminum alloy shelf rails.

These corrosion-resistant supports help facilitate shelf repositioning and routine cleaning.

Retailers can arrange shelves according to the dimensions of frozen food packages, boxed products, and suitable frozen desserts.

9. Self-Closing Glass Doors with Extended Handles

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

This reduces the risk of doors being unintentionally left open and helps limit warm-air infiltration.

Extended handles provide a convenient grip for routine customer and staff use.

10. Vertical LED Lighting and Reduced Condensate Handling

Vertical LED lighting along both interior sides helps illuminate frozen merchandise throughout the cabinet.

The self-evaporating condensate system is designed to reduce routine manual water disposal, while enlarged swivel casters facilitate cabinet positioning and maintenance access.
