Frequently Asked Questions about the Haier DW-86L959BPT

Why is Frequency Conversion Technology important for this ULT freezer?

This technology dynamically adjusts the compressor speed to the actual cooling demand inside the chamber. This massively reduces energy consumption compared to standard compressors, saving on operating costs. At the same time, it reduces mechanical stress, increases the unit's lifespan, and ensures extremely quiet operation.

Is the unit suitable for continuous operation at exactly -40°C?

No, the unit is optimized for a working temperature range of -60°C to -86°C. Due to the special cascade technology of the refrigeration system, continuous operation at only -40°C is technically not recommended. For medium freezing temperatures, dedicated laboratory freezers should be selected to protect the compressors.

How is storage temperature documented and monitored?

The unit features a 10-inch touchscreen display for real-time display of all parameters and an integrated USB interface for data download. A comprehensive alarm system monitors power failures, sensor errors, and temperature deviations both acoustically and visually. In addition, a potential-free contact enables connection to external remote alarm systems for seamless sample monitoring.

Technical data & description

The ultra-low temperature freezer was used from April 2023 to February 2024 for the storage of the BioNTech vaccine "Comirnaty". It was located in an air-conditioned hall and was only opened once every few months. Subsequently, it was kept as a backup unit in the switched-off state. It may show slight signs of use. Technically, it is virtually indistinguishable from a new unit. Max. capacity: 700 cryoboxes (50 mm high) in 28 racks of 25 boxes each Frequency Conversion Technology: load-dependent compressor frequency reduces power consumption to only 9.8 kWh/24h and the noise level to 47 dB(A). Furthermore, high temperature stability of +/-3°C.
