The Realmann BD-700D / BD-900D / BD-1000D Commercial Double Lid Chest Freezer Series is designed for businesses requiring substantial frozen food storage capacity in a practical horizontal cabinet. Available in three usable capacities of 670L, 850L, and 945L, the series supports bulk frozen inventory management in commercial kitchens, restaurants, supermarkets, food processing facilities, and frozen food distribution operations.

Unlike conventional single-lid chest freezers, the BD-D Series features a double top-opening lid design, allowing operators to access different areas of the freezer without necessarily opening the entire cabinet. Each lid is equipped with an external locking handle, providing convenient access and basic security for stored merchandise.

The freezer uses a static refrigeration system designed to maintain temperatures at approximately −18°C or below under rated operating conditions. Its 80mm thick cabinet insulation helps reduce heat transfer between the frozen compartment and the surrounding environment, supporting continuous commercial frozen food storage.

The BD-D Series features an adjustable thermostat for temperature management, a main power indicator for basic operating checks, and a defrost drain outlet to facilitate water removal during manual defrosting and cleaning.

Two internal storage baskets are included as standard, providing convenient space for frequently accessed frozen products. Adjustable bottom feet support stable installation on suitable flooring.

Depending on the selected model, the technical specifications list R134a, R290, or R600a refrigerant configurations. The appropriate refrigerant should be selected according to the final equipment design and destination-market requirements.

For additional operating convenience, buyers can choose optional internal LED lighting, an external condenser configuration, casters, full-basket arrangements, a digital thermometer, and a stainless steel top cover.

As a commercial chest freezer manufacturer, Realmann provides wholesale supply and OEM/ODM manufacturing support for foodservice equipment distributors, frozen food businesses, and international refrigeration importers.

Key Features & Benefits

1. Double Top-Opening Lids for Convenient Access

The BD-D Series features two separate top-opening lids, providing access to different areas of the storage compartment.

Compared with a single large lid, the double-lid construction allows operators to open one side when retrieving products stored in that section.

This arrangement can help limit unnecessary exposure of the entire cabinet opening during routine access, although actual heat loss depends on usage patterns and equipment construction.

2. Large Storage Capacities from 670L to 945L

The series provides three storage configurations for commercial frozen inventory.

These models allow buyers to select frozen storage volume according to operational requirements, cabinet footprint, and available installation space.

3. 80mm Thick Insulated Cabinet

All three models incorporate an 80mm thick cabinet structure specified for thermal insulation.

The insulation helps reduce heat transfer into the freezer compartment, supporting the low-temperature storage environment.

This construction is especially relevant to larger commercial chest freezers that may operate continuously in foodservice or storage facilities.

4. Static Cooling for Bulk Frozen Food Storage

The freezer uses direct, or static, refrigeration without relying on a fan to circulate cold air inside the storage compartment.

The specified storage temperature is approximately −18°C or below, depending on model and operating conditions.

This makes the series suitable for appropriately packaged frozen products that require conventional commercial freezer temperatures.

5. Lockable External Handles for Inventory Security

Each freezer is equipped with external locking handles.

These provide convenient lid operation while allowing businesses to restrict casual access to stored frozen merchandise.

The locking arrangement is useful in shared commercial kitchens, food storage areas, and retail backrooms.

6. Adjustable Thermostat for Temperature Management

An adjustable thermostat allows operators to select refrigeration settings according to the required storage conditions.

The mechanical control provides a straightforward interface for everyday freezer operation.

Actual cabinet and product temperatures should be verified with an appropriate thermometer when precise storage conditions are required.

7. Two Standard Storage Baskets

Every model includes two internal storage baskets.

These baskets help organize frequently accessed products and separate smaller packages from larger frozen inventory stored in the main compartment.

An optional full-basket configuration is available for businesses requiring additional interior organization.

8. Adjustable Bottom Feet for Stable Installation

Adjustable feet allow the freezer to be leveled on suitable flooring.

Proper leveling helps maintain stable cabinet positioning and appropriate lid alignment.

Optional casters are available where additional mobility is required.

9. Main Power Indicator and Defrost Drain

The main power indicator provides a visual reference showing whether electrical power is supplied to the appliance.

A defrost drain outlet facilitates water removal during manual defrosting and cleaning.

Both features support basic operating checks and routine maintenance.

10. Flexible Refrigerant Configurations

The supplied specifications list alternative refrigerant configurations for different models.

• BD-700D: R134a or R290

• BD-900D: R134a or R600a

• BD-1000D: R134a or R600a

Each appliance uses the refrigerant specified for its final refrigeration circuit. Refrigerants are not interchangeable without appropriate system design and validation.

11. Optional Stainless Steel Top Cover

A stainless steel top cover is available as an optional configuration.

This provides an additional exterior material option for equipment buyers with specific appearance or maintenance requirements.

The material grade and final construction should be confirmed before ordering.

12. OEM/ODM Options for Commercial Refrigeration Buyers

Realmann supports optional LED lighting, condenser configurations, cabinet mobility, basket arrangements, and temperature monitoring accessories.

These options allow equipment distributors and wholesale customers to discuss specifications for different commercial markets and applications.

Technical Specifications

BD-700D / BD-900D / BD-1000D Comparison

Specifications follow the supplied manufacturer table. The BD-700D temperature is written as −18°C, while the other two models are specified as ≤ −18°C. The table lists ST climate class, whereas the descriptive material states SN/T; the correct classification requires manufacturer confirmation. Refrigerant listings indicate alternative model configurations rather than simultaneous refrigerant use.

Standard and Optional Features

Commercial Applications

1. Restaurant and Hotel Kitchen Frozen Storage

The BD-D Series offers substantial freezer capacity for restaurants, hotel kitchens, and commercial food preparation facilities.

The double-lid design provides practical access to different storage areas, while the large cabinet volume accommodates appropriately packaged frozen ingredients and prepared foods.

The BD-700D can be considered for operations requiring approximately 670L of frozen storage.

2. Frozen Meat and Seafood Inventory

Foodservice operators and seafood suppliers can use these freezers to store appropriately packaged frozen meat, fish, and seafood.
