The Realmann SD-420QIC and SD-520QIC Curved Glass Ice Cream Display Freezers are designed for organized frozen product storage and self-service merchandising in convenience stores, supermarkets, ice cream retail outlets, and grocery shops.

Available with 355L and 445L usable capacities, the two models provide medium-capacity horizontal freezing solutions for retailers seeking an accessible display format without installing a larger commercial freezer island.

The cabinets feature newly designed curved sliding glass lids, allowing customers to view packaged frozen merchandise from above. The sliding mechanism provides convenient product access without the outward opening space required by hinged lids.

A static refrigeration system is specified to maintain freezer temperatures at or below −18°C under rated operating conditions. The cabinet incorporates 70mm thick insulation to help reduce heat transfer and support frozen storage.

The freezer exterior features an electrostatically coated finish with aluminum alloy profiles along the front and rear cabinet openings. These components provide a practical structure for commercial retail operation.

Inside the cabinet, reinforced storage baskets help organize packaged ice cream, frozen snacks, frozen vegetables, and other temperature-compatible products. The SD-420QIC includes four baskets, while the SD-520QIC provides five baskets. Integrated LED lighting improves merchandise visibility through the curved glass lids.

A seven-position mechanical thermostat supports straightforward temperature adjustment, while a main power indicator provides visual confirmation of electrical supply.

For routine maintenance, the freezer includes a bottom-mounted defrost drain for water removal during cleaning or manual defrosting. Two fixed-direction wheels and two swivel casters allow staff to position the cabinet more conveniently.

As a commercial ice cream display freezer manufacturer, Realmann supports wholesale and OEM/ODM cooperation for refrigeration distributors, frozen food suppliers, and retail equipment procurement projects.

Key Features & Benefits

1. Curved Glass Top for Ice Cream Merchandising

Actual energy consumption depends on the complete refrigeration system, ambient temperature, product loading, and customer usage.

4. Static Cooling for Frozen Storage

The SD-420QIC and SD-520QIC use a static, or direct, cooling system.

Rather than circulating cold air with a fan, the system transfers heat through refrigerated cabinet surfaces.

The specified operating condition is −18°C or below, suitable for products whose storage requirements are compatible with that temperature.

5. Seven-Position Mechanical Temperature Control

The standard mechanical thermostat offers seven adjustable positions.

This provides a simple control method for retail operators without requiring a digital control interface.

Actual cabinet temperature should be checked with an appropriate thermometer because numbered thermostat positions do not represent fixed temperature values.

6. Reinforced Food Baskets for Organized Storage

The SD-420QIC includes four storage baskets, while the SD-520QIC includes five.

The reinforced basket arrangement allows retailers to separate frozen products by flavor, type, packaging, or brand.

This supports easier stock organization and replenishment during daily retail operation.

7. Integrated LED Lighting

Both models feature built-in LED lighting as standard.

The illumination helps customers identify products inside the cabinet and supports visibility during product restocking.

8. Electrostatic-Coated Exterior with Aluminum Alloy Rims

The exterior cabinet uses an electrostatic coating, while aluminum alloy profiles reinforce the front and rear rim areas.

This construction supports a clean commercial appearance and provides practical edging around the glass lid opening.

9. Bottom Defrost Drain for Routine Maintenance

A bottom-mounted defrost water outlet allows collected water to be removed during manual defrosting and cleaning.

This helps simplify maintenance when frost removal is required.

10. Four-Wheel Cabinet Mobility

The freezer uses two fixed-direction wheels and two swivel casters.

The combination provides directional movement and maneuverability for positioning the cabinet during installation, cleaning, or store layout changes.
