The BDW-25L300RF Combined Refrigerator and Deep Freezer integrates two independent temperature-controlled zones — 200L refrigerator at 2–8°C and 100L deep freezer at -10 to -25°C — with independent microprocessor control, high-efficiency compressor, digital display, battery backup alarm continuity, mechanical lock, password protection, and optimised airflow design in a single 330W floor-standing unit for pharmaceutical, hospital, and research laboratory storage.
The BDW-25L300RF's defining feature is its dual independent temperature zones — the 200L upper refrigerator chamber maintained at 2°C to 8°C for pharmaceutical, biological, and diagnostic material refrigerated storage, and the 100L lower deep freezer chamber maintained at -10°C to -25°C for frozen sample, reagent, and vaccine storage. Both zones maintain their target temperatures independently — changes in one zone do not affect the other — with 0.1°C temperature resolution displays for precise monitoring of actual temperature in both compartments simultaneously.
The BDW-25L300RF's two storage zones are served by independent cooling systems — providing separate temperature regulation circuits for the refrigerator and freezer compartments. Independent cooling systems ensure that the thermal performance of one zone is not compromised by the demands of the other — preventing the temperature cross-talk that occurs in shared-cooling dual-zone units, where heavy freezer duty can temporarily affect refrigerator temperature stability. This independence is critical for pharmaceutical and clinical applications where both zones must simultaneously maintain their defined temperature ranges.
The BDW-25L300RF uses a high-efficiency compressor that achieves fast temperature recovery after door opening — reaching the refrigerator setpoint within ≤0.8 hours and the freezer setpoint within ≤2.6 hours from ambient. Rapid recovery is essential for pharmaceutical and clinical storage applications where frequent door access during active working hours must not result in sustained temperature deviations that compromise stored material integrity or temperature excursion documentation requirements.
The BDW-25L300RF's optimised airflow design distributes temperature-controlled air uniformly throughout both the 200L refrigerator and 100L freezer compartments — maintaining temperature uniformity of ≤±4°C throughout each zone. Uniform temperature distribution ensures that samples, reagents, and biological materials stored at any position within each compartment — from front to back, top shelf to bottom drawer — experience consistent temperature conditions within the specified range rather than localised warm or cold spots that can occur in non-optimised refrigeration designs.
The BDW-25L300RF is designed for low-noise operation — ensuring that the compressor and refrigeration system do not create acoustic disruption in shared laboratory, clinical, and hospital ward environments where noise management is an important operational and occupant wellbeing consideration. Low-noise refrigeration system design is achieved through vibration-damped compressor mounting, optimised refrigerant flow noise reduction, and sealed insulation that attenuates mechanical noise from the refrigeration circuit.
The BDW-25L300RF uses R290 (propane, HC) refrigerant — a natural hydrocarbon refrigerant with zero ozone depletion potential (ODP = 0) and extremely low global warming potential (GWP = 3) compared to conventional HFC refrigerants (GWP typically 1000–4000). R290 also provides excellent thermodynamic efficiency, contributing to the BDW-25L300RF's energy efficiency at 330W rated power. For pharmaceutical organisations and healthcare institutions with environmental sustainability commitments, the R290 refrigerant system supports ESG reporting and green procurement objectives.
The BDW-25L300RF's cooling systems achieve temperature recovery to the refrigerator setpoint within ≤0.8 hours and to the freezer setpoint within ≤2.6 hours after door opening — performance specifications that ensure pharmaceutical and clinical storage materials are returned to their required temperature range rapidly following routine access events. These recovery times support compliance with pharmaceutical storage temperature excursion monitoring requirements and minimise the duration of any temperature deviation records generated during normal daily access to both compartments.
The BDW-25L300RF provides 2 adjustable shelves and 3 drawers across 6 storage levels — offering flexible storage organisation for diverse pharmaceutical, biological, diagnostic, and research materials across both zones. The adjustable shelves in the 200L refrigerator accommodate varied-height pharmaceutical storage containers, while the 3 drawers in the 100L freezer provide organised frozen sample management with easy pull-out access — reducing the duration and frequency of door open events required for frozen sample retrieval during busy laboratory periods.
The BDW-25L300RF Combined Refrigerator and Deep Freezer incorporates ten independent safety, monitoring, and security systems — covering temperature alarms, power failure protection, sensor integrity, door management, battery backup continuity, mechanical security, and automatic recovery — providing comprehensive protection for high-value pharmaceutical, biological, and clinical materials in continuous 24/7 laboratory and hospital storage.
The BDW-25L300RF provides both audible and visual alarms for all alert conditions in both the refrigerator and freezer zones — ensuring that temperature, power failure, and door open events are communicated immediately to operators regardless of proximity or laboratory noise levels. The dual-mode alarm system is critical for 24/7 pharmaceutical and clinical storage applications where unattended overnight operation requires reliable alarm escalation for any storage condition deviating from the defined temperature requirements.
The BDW-25L300RF monitors both the refrigerator (2–8°C) and freezer (-10 to -25°C) zones continuously and activates high and low temperature alarms when either zone temperature exceeds the configured threshold. High and low temperature alarms are independently configured for each zone — allowing appropriate alarm thresholds to be set based on the sensitivity of the specific materials stored in each compartment. This dual-zone alarm independence provides customised protection for the different temperature-critical materials simultaneously stored in the refrigerator and freezer sections.
The BDW-25L300RF activates a power failure alarm immediately upon interruption of the electrical supply — alerting operators to loss of active cooling before temperature in either storage zone rises to a level that could compromise stored materials. In pharmaceutical, blood bank, and vaccine storage applications where regulatory and quality requirements mandate documentation of all temperature excursion events including those caused by power interruptions, the power failure alarm provides the immediate notification required to initiate emergency response procedures.
The BDW-25L300RF continuously monitors the operational integrity of temperature sensors in both the refrigerator and freezer zones, activating sensor failure alarms if either sensor malfunctions. In a combined pharmaceutical and clinical storage unit operating 24/7, undetected sensor failure could allow temperature deviations to persist without alarming — the sensor failure alarm system ensures monitoring gaps in either zone are immediately communicated to operators for prompt investigation and corrective action.
The BDW-25L300RF's door open alarm activates when either the refrigerator or freezer door remains open beyond the configured time threshold — preventing sustained temperature deviations caused by inadvertent door left-open events during busy clinical or laboratory working periods. In vaccine storage, blood bank, and pharmaceutical cold chain management applications, documented door management compliance is an important quality assurance requirement — the door open alarm supports this compliance through automatic alerting of door closure non-conformances.
The BDW-25L300RF incorporates a built-in battery backup system that maintains alarm display and alert functionality during power outage — ensuring that power failure alarms, temperature excursion alerts, and storage status information remain visible to operators even when mains power is interrupted. In hospitals, clinical laboratories, and pharmaceutical storage facilities where power outages can occur during non-working hours, the battery backup alarm continuity provides the critical notification capability for emergency response to power interruption events affecting stored pharmaceutical and biological materials.
The BDW-25L300RF's mechanical door lock secures both the refrigerator and freezer compartments against unauthorised access — a critical security feature for pharmaceutical storage, controlled medicine management, blood product storage, and vaccine programmes where regulatory requirements mandate physical access control to temperature-controlled storage. The mechanical lock provides reliable physical security independent of the electronic control system — ensuring that access control is maintained even during power interruptions or electronic system maintenance events.
The BDW-25L300RF's password protection system prevents unauthorised changes to temperature setpoints, alarm thresholds, and operational parameters — ensuring that only authorised personnel can modify the storage conditions for pharmaceuticals, blood products, vaccines, or biological reference materials. Password-protected parameter management is a standard quality management requirement for pharmaceutical and clinical storage equipment — the BDW-25L300RF's built-in password system supports GxP and regulatory compliance without requiring external software or separate access control systems.
The BDW-25L300RF automatically restores both cooling systems to their pre-interruption temperature setpoints when mains power is restored after an outage — without requiring manual operator reset. Automatic restart is a critical pharmaceutical and clinical storage feature: manual restart requirement after power restoration would extend the temperature recovery period during unattended overnight events, increasing the duration of any temperature excursion and potentially pushing materials outside their defined storage temperature ranges for longer than necessary.
The BDW-25L300RF enters a defined safe mode operation state in the event of a sensor failure — maintaining cooling operation at conservative defined parameters designed to protect stored materials even when accurate temperature monitoring is unavailable. Safe mode operation prevents a sensor failure event from immediately compromising stored pharmaceutical, biological, or clinical materials — providing a protective holding condition that allows time for sensor replacement and restoration of normal monitored operation.
