SD-Q Series Commercial Curved Glass Sliding Lid Chest Freezer

The Realmann SD-Q Commercial Curved Glass Sliding Lid Chest Freezer Series is designed for frozen food storage and customer-facing merchandising in supermarkets, convenience stores, grocery outlets, and frozen dessert retail locations. Available in six models with usable capacities ranging from 180L to 615L, the series combines a horizontal display layout with curved sliding glass lids for convenient product access.

Unlike upright glass door freezers, the SD-Q Series uses a direct cooling system and a chest-style cabinet, allowing frozen products to be arranged in removable storage baskets beneath a transparent sliding glass top.

The new curved glass lid design provides a clear view of packaged frozen foods while allowing customers to slide open the cabinet for product selection. A 70mm thick insulation layer helps reduce heat transfer through the cabinet body, supporting frozen storage at a specified temperature of −18°C or below under rated operating conditions.

For merchandising flexibility, the series includes two to seven reinforced food baskets depending on the selected model. Built-in LED lighting helps illuminate the cabinet interior, improving visibility of ice cream, frozen vegetables, packaged meat, and other compatible frozen products.

The freezer features an electrostatically coated exterior cabinet, aluminum alloy front and rear rim profiles, and a seven-position adjustable mechanical thermostat. A main power indicator provides a convenient visual indication of the electrical supply.

A bottom-mounted defrost drain outlet supports water removal during cleaning and manual defrosting. Two fixed-direction wheels and two swivel casters facilitate positioning and movement during retail installation.

Optional electronic temperature control and a rear advertising light box are available for buyers seeking additional control features or branded freezer displays.

As a commercial chest freezer manufacturer, Realmann supports OEM/ODM and wholesale inquiries for frozen food distributors, supermarket equipment suppliers, and ice cream merchandising projects.

Key Features & Benefits

1. Curved Sliding Glass Lids for Easy Product Access

The SD-Q Series features a newly designed curved sliding glass lid, providing a clear overhead view of frozen merchandise.

Customers can slide the lid open to access products without requiring the outward opening clearance of a hinged door.

The curved glazing creates an attractive display profile suitable for supermarkets, ice cream retail areas, and self-service frozen food sections.

2. 70mm Thick Cabinet Insulation

The freezer incorporates a 70mm thick insulation layer within the cabinet structure.

This insulation helps reduce heat transfer between the frozen interior and the surrounding environment, supporting low-temperature storage.

Actual energy consumption depends on the complete refrigeration system, ambient conditions, product loading, and frequency of customer access.

3. Direct Cooling System for Frozen Storage

The freezer uses a direct cooling system rather than fan-forced air circulation.

Cooling is transferred through the cabinet’s refrigeration surfaces, supporting frozen storage at a specified temperature of −18°C or below.

As with other static cooling systems, periodic manual defrosting may be necessary depending on frost accumulation and operating conditions.

4. Six Usable Capacity Options from 180L to 615L

The SD-Q Series includes six models for different merchandising requirements.

This range allows buyers to select compact freezers for smaller shops or wider cabinets for supermarket frozen food aisles.

5. Seven-Position Mechanical Temperature Control

Each model is equipped with a seven-position adjustable mechanical thermostat.

Operators can select the control setting according to the required freezing conditions and product storage requirements.

An electronic temperature controller is available as an optional configuration.

6. Reinforced Food Storage Baskets

The freezer includes reinforced food baskets designed to support organized product placement.

Depending on the selected model, two to seven baskets are provided as standard.

These baskets help separate frozen products by type, brand, or package size, making stock organization and replenishment more convenient.

7. Built-In LED Interior Lighting

An integrated LED lighting system is included as standard.

The lighting helps illuminate products stored beneath the glass lids, making it easier for customers to identify merchandise and for staff to manage stock.

8. Durable Electrostatic-Coated Exterior

The cabinet exterior features an electrostatic powder-coated finish.

Aluminum alloy rim profiles at the front and rear provide a practical cabinet edge structure suitable for everyday commercial use.

This construction supports a clean appearance and routine maintenance in retail environments.

9. Convenient Bottom Defrost Drain

A drain outlet positioned near the cabinet bottom facilitates water removal during defrosting and cleaning.

This helps simplify maintenance compared with cabinets that require water to be removed manually from the interior.

The drain should be used in accordance with the manufacturer’s operating instructions.

10. Four-Wheel Mobility Configuration

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

This arrangement supports directional movement and maneuverability during installation, cleaning, and store layout adjustments.

11. Optional Electronic Control and Rear Light Box

For commercial projects requiring additional features, the SD-Q Series offers an optional electronic temperature controller and a rear-mounted illuminated advertising panel.

These options can be considered for branded frozen food and ice cream merchandising programs.
