The BDW-86L490 Ultra-Low Temperature Freezer extends the BDW-86L390's certified -86°C biological sample storage platform to 490L — accommodating 16 racks for 320 storage boxes and supporting larger pharmaceutical biological material libraries, extended biobank collections, and higher-capacity research institution biological archives requiring more storage volume than the standard 390L format provides. The BDW-86L490 maintains the full BDW-86L390 feature platform — touch screen controller, data logging, 126mm non-HCFC polyurethane insulation, SS304 stainless steel interior, antibacterial steel exterior, 4 independent inner doors, seven-alarm system, battery backup, mechanical lock, vent port, gasket heating, and CE/RoHS certification — applied to the larger 490L cabinet with identical -86°C performance specifications.
The BDW-86L490 provides 490L of -86°C higher-capacity ultra-cold biological sample storage — with 126mm polyurethane insulation, SS304 interior, 4 inner doors, touch screen data logging, 16 racks/320 boxes capacity, battery backup, mechanical lock, gasket heating, and CE/RoHS certification for pharmaceutical, biobank, and research institution higher-capacity biological material preservation.
The BDW-86L490's 490L nominal capacity and 16-rack/320-box configuration provides 33% more storage volume and 33% more storage boxes than the BDW-86L390's 390L/240-box configuration — accommodating larger pharmaceutical biological reference standard libraries, extended longitudinal biobank sample collections, and higher-volume research institution biological material archives within a single monitored, documented, and secured -86°C storage unit. The 589 × 637 × 1310 mm internal dimensions provide greater internal depth than the BDW-86L390's 589 × 505 × 1310 mm, accommodating the additional rack positions within the same external cabinet height.
The BDW-86L490's touch screen provides intuitive parameter management, real-time temperature display, and alarm threshold configuration for the higher-capacity biological material collection — providing the same comprehensive operational control as the BDW-86L390 across the larger 490L storage environment.
The same 126mm insulation thickness as the BDW-86L390 provides equivalent thermal resistance and energy efficiency for the larger 490L cabinet — maintaining -86°C against the ambient temperature differential with the same compressor duty cycle efficiency that characterises the standard model.
SS304 interior enables thorough cleaning of the larger 490L storage environment after biological material spills or periodic deep cleaning, while the antibacterial exterior coating maintains the infection control standards of hospital, pharmaceutical, and biobank installation environments.
Multi-layer sealing prevents cold air leakage at the larger door perimeter; gasket heating prevents frost formation at -86°C; and 4 independent inner doors minimise per-access cold air loss across the higher-volume 490L storage environment — maintaining the cold chain management performance of the standard model at the larger capacity.
Continuous data logging provides complete electronic temperature history for pharmaceutical cold chain documentation and biobank quality management compliance across the larger 490L biological material collection, and battery backup maintains alarm monitoring and notification continuity throughout power interruption events.
The BDW-86L490 incorporates the full BDW-86L Series seven-alarm system — high condenser temperature, power failure, sensor failure, low battery, high/low temperature, and door open alarms plus mechanical lock — providing comprehensive cold chain protection for the larger 490L biological material collection.
Early warning of refrigeration system anomalies before compressor failure threatens the larger 490L biological material collection.
Immediate notification of power interruption and temperature excursions for the higher-value larger biological material collection requiring emergency response before critical temperature thresholds are reached.
Complete monitoring coverage for the larger 490L storage environment throughout operational periods and power interruptions.
Physical access security for the larger pharmaceutical, biobank, and research institution biological material collection.
