BDW-86L390 Ultra-Low Temperature Freezer
Built on a reliable, optimized two-stage cascade compression refrigeration system with widely available eco-friendly refrigerants and advanced manufacturing processes, the BeiYin ultra-low temperature freezer series is designed to guarantee personnel safety, sample safety, equipment safety and environmental safety, and is certified to CE and RoHS.
-50 ~ -86°C | 7-inch LCD Touch Screen | 126 mm High-Density Insulation | CE & RoHS Certified
After rigorous performance and life-cycle testing, the BeiYin ultra-low temperature freezers are ensured to operate safely and reliably over long periods of continuous use.
Product Features
- Touch screen interface: Strong human-machine interaction with simple and convenient operation.
- 7-inch LCD touch screen display.
- Robust cabinet: The exterior is made of high-strength cold-rolled steel sheet with a powder-coated surface.
- 304 stainless steel interior liner.
- Adjustable shelves: Stainless steel shelf brackets are height-adjustable and can be installed or removed at will, making cleaning of the inner chamber easy.
- High-density insulation: The insulation layer uses high-density R245fa polyurethane integral foaming. The 126 mm thick foam layer has an extremely low thermal conductivity for greater energy efficiency. R245fa foaming agent is eco-friendly, highly flame-retardant and non-flammable for greater safety.
- Ergonomic door handle: Bionic design with a long lever arm allows one-handed door opening.
- Mechanical lock provided, with padlock hole.
- Reinforced shelves: Each shelf supports a maximum load of 50 kg.
- Backup battery: Keeps the display powered during a power outage.
- Internal and external pressure equalization valve.
- Anti-condensation function.
- Foamed inner doors.
- Heavy-duty leveling casters.
Three-Level Permission Management
- Multiple accounts with different permission levels can be assigned. According to equipment management needs, controller operating permissions can be assigned to three permission levels: administrator, operator and visitor.
Data Logging and Remote Control
- Temperature records can be exported via the USB port on the control panel.
- Remote alarm connection port provided.
- RS-485 interface provided.
Alarm and Protection
- Audible and visual alarms.
- Comprehensive alarms: power failure, high/low temperature, low battery, filter cleaning required, sensor failure, refrigeration system failure, door open too long, and more.
- Complete protection: power-on delay protection and compressor overheat protection.
- Alarm records: all fault alarms and warnings are fully recorded and can be downloaded for review.
- Backup battery: after a power failure, the fully charged backup battery displays the cabinet temperature and power failure alarm information in real time for at least 48 hours.
- Self-diagnosis: when the freezer malfunctions, the display shows the corresponding fault.
Optional Accessories
- CO2 and LN2 backup system: automatic switching safeguards your samples even during a power failure.
- Face recognition: visualized login strictly controls sample access permissions; history of all logged-in users is traceable, with a record capacity of up to 100,000 entries.
- Second in-cabinet temperature sensor: can be placed at different positions as needed, or used to verify the main control sensor.
- Temperature recorder: plug-and-play for quick and convenient use; one-click generation of GMP-compliant PDF reports improves efficiency.
- Paper temperature recorder: provides traceable data records.
- Cryogenic racks and cryoboxes: standard racks and boxes supply everything you need in one stop.
- Power voltage stabilizer: provides stable voltage output when the supply fluctuates abnormally within 160 V to 250 V.
- Remote camera monitoring: allows users to check the freezer’s operating status anytime, anywhere.
