It is designed for safe, reliable refrigeration of biological samples, vaccines and blood products in hospitals, clinics and blood banks, maintaining the required storage temperature and alarms for preservation.
The unit is designed to maintain a storage temperature of 4 ± 1°C. It is intended to operate in ambient temperatures from 10°C to 32°C.
The fridge uses forced‑air cooling for even temperature distribution and has an automatic defrost function to minimize manual maintenance.
The system uses R134a refrigerant, which is an efficient, widely used option with lower environmental impact compared with older CFC refrigerants.
The interior is made from stainless steel 304 for corrosion resistance and long service life. The outer cabinet is SPCC steel with a powder coating for durability.
The BN-4U88 has a rated power of 175 W and is designed for energy‑efficient operation. Actual daily energy use varies by model and load; consult the full spec sheet for model‑specific kWh/24h figures.
Yes. The series supports alarms for high/low temperature, power failure, sensor error, low battery and door‑ajar conditions. Optional temperature recorders and a USB interface are available for monitoring and data export.
An optional USB interface and optional temperature recorder are available for remote monitoring and data logging. Check the chosen model and options when ordering.
Routine tasks include keeping door seals clean, ensuring adequate airflow around the unit, checking alarm function and calibration periodically, and following the auto‑defrost schedule. Have qualified service personnel perform electrical and refrigeration maintenance as needed.
The BOYN blood bank lineup comes in multiple upright sizes and capacities to suit different needs (examples across the range include 88 L up to over 1000 L). Choose a model based on your storage volume and blood bag capacity requirements.
Yes, provided the ambient temperature remains within the specified 10°C–32°C range, there is adequate ventilation/clearance, and the unit is installed on a stable, level surface and connected to a suitable dedicated power supply (220 V, 50 Hz).
Yes. Models are equipped with LED interior lighting for clear visibility. Shelves and baskets are provided depending on the model; additional or specialized shelving configurations may be available as accessories.
Some models include a door lock with key or can be fitted with optional access control accessories. Verify the specific model configuration and available accessories when ordering.
Noise levels vary by model, but the units are designed to operate quietly for laboratory and clinical environments. Typical acoustic levels are within normal appliance ranges; consult the model specification for exact dB(A) figures.
Confirm model‑specific alarm functions, temperature accuracy and recorder options, refrigerant type, electrical requirements, and that the unit meets your local regulatory and storage protocol requirements for blood and medical products.
