The Realmann SD-P Commercial Flat Glass Sliding Lid Chest Freezer Series provides practical frozen food storage and customer-facing merchandising for supermarkets, convenience stores, grocery shops, and frozen food retailers. Featuring a horizontal cabinet with flat sliding glass lids, the series allows customers to view frozen merchandise from above while providing convenient access to products stored inside.

Available in four models—SD-320P, SD-420P, SD-520P, and SD-620P—the range offers usable capacities of 273L, 355L, 445L, and 545L to accommodate different retail display requirements.

Unlike curved glass chest freezers, the SD-P Series features a flat glass top profile, creating a streamlined appearance suitable for organized supermarket freezer layouts. The sliding lid design allows customers to access frozen products without requiring additional outward door-opening clearance.

The freezer uses a static cooling system designed to maintain a specified storage temperature of −18°C or below under rated operating conditions. A 70mm thick cabinet insulation layer helps limit heat transfer and supports low-temperature storage.

The exterior features an electrostatically coated finish with aluminum alloy front and rear rim profiles, providing a practical structure for commercial applications.

Inside the cabinet, reinforced food storage baskets help separate frozen products by category and improve merchandise organization. Depending on the model, three to six baskets are included as standard. Integrated LED lighting helps illuminate the storage area, making packaged frozen products easier to identify through the glass lids.

A seven-position mechanical thermostat provides temperature adjustment, while a main power indicator allows operators to check the cabinet’s power status. The bottom-mounted defrost drain simplifies water removal during manual defrosting and cleaning.

Two fixed-direction wheels and two swivel casters support cabinet mobility for installation, store rearrangement, and routine floor cleaning.

An optional electronic temperature controller is available for buyers who require a digital control configuration.

As a commercial chest freezer manufacturer, Realmann supports OEM/ODM and wholesale inquiries from refrigeration distributors, frozen food brands, and supermarket equipment suppliers.

Key Features & Benefits

1. Flat Sliding Glass Lids for Streamlined Merchandising

The SD-P Series incorporates flat sliding glass lids that provide an unobstructed overhead view of frozen merchandise.

Compared with curved glass configurations, the flat lid design creates a level upper profile and a clean appearance suitable for commercial freezer displays.

Customers can slide the lids open to select products without requiring additional space for hinged door movement.

2. 70mm Thick Thermal Insulation

The cabinet incorporates a 70mm thick insulation layer that helps reduce heat transfer between the freezer interior and surrounding environment.

This insulation supports frozen storage and helps the cabinet maintain low internal temperatures under intended operating conditions.

Actual energy performance depends on the refrigeration system, installation environment, thermostat settings, and frequency of lid openings.

3. Static Cooling for Frozen Food Storage

The direct cooling system transfers refrigeration through the cabinet’s internal cooling surfaces without using a fan to circulate cold air.

The freezer is specified for temperatures of −18°C or below, making it suitable for frozen products that require these storage conditions.

Periodic manual defrosting may be necessary depending on frost accumulation and operating conditions.

4. Four Capacity Options from 273L to 545L

The SD-P Series includes four models for different freezer merchandising requirements.

These configurations allow retailers to select appropriate storage volume according to floor space, product assortment, and sales requirements.

5. Seven-Position Adjustable Mechanical Thermostat

The freezer includes a mechanical thermostat with seven adjustment positions.

This allows operators to select temperature control settings according to operating requirements.

The control positions should not be interpreted as exact temperatures without the manufacturer’s calibration information.

An electronic temperature controller is available as an optional configuration.

6. Reinforced Food Storage Baskets

The interior includes reinforced storage baskets designed to organize frozen merchandise.

Each model provides a different standard basket quantity:

• SD-320P: 3 baskets

• SD-420P: 4 baskets

• SD-520P: 5 baskets

• SD-620P: 6 baskets

The basket layout helps separate products and makes replenishment more convenient for retail personnel.

7. Integrated LED Interior Lighting

Built-in LED lighting is included as standard.

The lighting illuminates the freezer interior, improving product visibility through the flat glass lids and supporting easier stock identification.

8. Electrostatic-Coated Exterior Cabinet

The freezer features an electrostatically coated exterior surface intended for everyday commercial use.

Aluminum alloy rim profiles at the front and rear provide structural edging around the cabinet opening.

The combination creates a practical exterior for supermarkets, convenience stores, and frozen food outlets.

9. Bottom Defrost Drain and Power Indicator

A bottom-mounted defrost drain provides an outlet for water removal during cabinet defrosting and cleaning.

The main power indicator offers a simple visual confirmation that electrical power is supplied to the freezer.

These features support routine equipment checks and maintenance.

10. Two Fixed Wheels and Two Swivel Casters

The standard wheel configuration includes two fixed-direction wheels and two swivel casters.

This arrangement supports directional movement and maneuverability when positioning the freezer or cleaning the surrounding floor.

Sliding lids allow product access without the outward clearance required by hinged covers.

3. Ice Cream and Frozen Dessert Retail

The freezer can be used for packaged ice cream and selected frozen desserts when the temperature requirements of the products are compatible with the cabinet’s rated performance.

Integrated LED lighting improves visibility of stored products, while the basket configuration helps organize different flavors or package types.

4. Frozen Vegetable and Packaged Food Sections

The SD-P Series supports appropriately packaged frozen vegetables, prepared meals, and other frozen food items.

Removable storage baskets can be used to separate product categories and simplify replenishment.

Temperature settings should be selected according to the required storage conditions.

Frequently Asked Questions (FAQ)

Q1: What is a flat glass sliding lid chest freezer?

A flat glass sliding lid chest freezer is a horizontal commercial freezer with transparent, flat glass panels that slide open for product access.

It is designed to display and store frozen merchandise while allowing customers to browse products through the glass lids.

Q2: What is the difference between flat glass and curved glass chest freezers?

The primary difference is the shape of the glass lid.

Flat glass chest freezers have a level glass top profile, while curved glass models use an arched lid design.

Both can support overhead product visibility and sliding access, but their external appearance and display geometry differ.

Q3: What temperature range does the SD-P Series support?

The freezer is specified for temperatures of −18°C or below under rated operating conditions.

Actual internal temperatures depend on thermostat settings, ambient conditions, product loading, and lid-opening frequency.

Q4: How thick is the cabinet insulation?

All four models feature a 70mm thick insulation layer.

This helps limit heat transfer through the cabinet body and supports low-temperature storage.
