272–550L Commercial Lockable Top Opening Chest Freezer

The Realmann BD-350, BD-450, BD-550 and BD-650 Commercial Chest Freezers are designed for businesses requiring secure, organized frozen food storage. Available in usable capacities from 272L to 550L, these top-opening freezers provide practical storage for restaurants, grocery stores, catering businesses, frozen food retailers and commercial foodservice facilities.

A distinctive feature of the series is its external handle with an integrated door lock, allowing operators to secure stored merchandise when the freezer is unattended. This design is useful in shared storage areas, small retail businesses and commercial locations where access control is important.

The cabinet uses a direct cooling system with R600a refrigerant and is specified to maintain temperatures of −18°C or below under rated operating conditions. A 75mm insulated cabinet structure helps reduce heat transfer between the freezer interior and the surrounding environment.

The series is classified for SN/T climatic conditions, making it suitable for a broad range of ambient temperatures within the relevant appliance standard. The manufacturer also lists an A+ energy efficiency classification, subject to confirmation of the applicable testing and destination-market labeling requirements.

An adjustable thermostat allows operators to select suitable temperature settings, while a main power indicator provides basic electrical status visibility. A built-in defrost drain simplifies water removal during manual defrosting and cleaning.

Each model includes one or two storage baskets depending on cabinet size. Optional configurations include internal LED lighting, an external condenser, casters, full-basket storage, a digital thermometer, adjustable bottom feet and a stainless steel top cover.

Available in white or silver exterior finishes, the BD Series offers flexible choices for commercial refrigeration distributors and equipment importers.

As a commercial chest freezer manufacturer, Realmann supports wholesale and OEM/ODM cooperation for private-label brands and commercial food storage projects.

Key Features & Benefits

1. Lockable External Handle for Secure Storage

The BD Series features an external lid handle with a built-in locking mechanism.

This enables operators to restrict casual access to frozen inventory during non-business hours or in shared commercial environments.

The integrated lock is particularly useful for grocery stores, small foodservice operations and frozen food storage areas requiring basic merchandise security.

2. 75mm Thick Cabinet Insulation

All four models incorporate 75mm thick cabinet insulation.

The insulation helps limit external heat gain and supports the freezer’s thermal performance during continuous operation.

Actual energy consumption depends on the refrigeration system, surrounding temperature, product loading and lid-opening frequency.

3. Four Storage Capacities from 272L to 550L

The series offers four different storage configurations.

These options allow buyers to match frozen inventory volume with available floor space.

4. R600a Direct Cooling System

The freezer uses R600a refrigerant and direct cooling technology.

Static refrigeration removes heat through the cabinet’s cooling surfaces without requiring an internal fan for air circulation.

R600a has a low global warming potential but is flammable, requiring appropriately designed equipment and safe servicing procedures.

5. SN/T Climate Classification

The BD Series is specified with an SN/T climate class.

Under commonly used refrigeration appliance standards, this designation generally corresponds to a rated ambient range from +10°C to +43°C.

For commercial installations, the actual rating plate and applicable testing standard should be checked to confirm suitability.

6. Manufacturer-Listed A+ Energy Classification

The supplied specification sheet lists an A+ energy efficiency rating for all four models.

This designation should be interpreted according to the relevant energy labeling scheme and test method.

Buyers should request the current energy label and measured consumption figures for the destination market before making efficiency comparisons.

7. Adjustable Temperature Control

An adjustable thermostat allows operators to manage freezer settings according to storage requirements.

The specified freezer temperature is −18°C or below, subject to rated operating conditions.

Operators should verify actual product storage temperatures when handling temperature-sensitive inventory.

8. Convenient Main Power Indicator

A main power indicator provides visual confirmation that electrical power is supplied to the appliance.

This supports basic routine checks by retail and foodservice staff.

The indicator does not independently confirm that the cabinet has reached its target temperature.

9. Built-In Defrost Drain

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

This is useful for commercial freezers that require periodic frost removal as part of routine maintenance.

10. Flexible Basket Storage

The BD-350 and BD-450 each include one standard basket, while the BD-550 and BD-650 provide two baskets.

The baskets support organization of frequently accessed products and help separate smaller packages from bulk frozen inventory.

A full-basket arrangement is also available as an option.

11. White and Silver Cabinet Finishes

The series is available in white or silver finishes.

These options allow distributors and retailers to choose cabinet appearances suited to their product range or installation environment.

12. Optional Commercial Convenience Accessories

Optional configurations include internal LED lighting, external condensers, casters, adjustable feet, full-basket arrangements, digital thermometers and stainless steel top covers.

Final availability should be confirmed according to model and production requirements.
