Product information

Energy-Efficient Ultra-Low Temperature Freezing for Biobanks and Research Laboratories

The Axofreeze -86°C ultra-low temperature freezer with 428 liters of usable volume was specifically designed for the safe long-term storage of biological samples in research institutions, biobanks, and clinical laboratories. With a capacity of 300 boxes and up to 30,000 samples, the unit offers ample space for extensive collections. The dual cooling system with two independent refrigeration circuits ensures maximum safety: if one compressor fails, the second compressor alone maintains -80°C continuously, reliably protecting valuable samples.

As an energy-saving model, the ultra-low temperature freezer consumes only 5.9 kWh per day at -75°C and operates at a low noise level of 49 dB(A). The frequency-controlled compressors enable particularly economical operation, while the CFC-free hydrocarbon-based refrigerant (R600a, R1150, R50) with a GWP = 0 meets the highest environmental standards. The 10.1-inch touchscreen control with USB and RS485 interfaces allows for convenient operation and network integration, while comprehensive alarm functions for temperature deviations, power failure, and system malfunctions provide safety at all times.

With its combination of energy efficiency, dual safety, and large capacity, this ultra-low temperature freezer is the ideal solution for demanding storage requirements. Discover our other solutions in the areas of ultra-low temperature freezers and cryogenics, or request a customized quote now.

Frequently Asked Questions About This Model

What is the Axofreeze -86°C ultra-low temperature freezer used for?

The unit is used for the safe long-term storage of biological samples at temperatures from -40°C to -86°C in research laboratories, biobanks, clinics, and pharmaceutical facilities. With a capacity of 300 boxes and 30,000 samples, it is suitable for extensive sample collections such as DNA, RNA, cell lines, tissue, and other temperature-sensitive materials.

What is the power consumption of the energy-saving model?

As an energy-saving model, the ultra-low temperature freezer consumes only 5.9 kWh per day at -75°C. The frequency-controlled compressors and the highly efficient vacuum insulation panel (VIP+) with 90 mm thickness in polyurethane ensure minimal energy consumption with maximum cooling performance. The CFC-free hydrocarbon-based refrigerant also has a GWP value of 0.

Which laboratories and industries is the unit particularly suitable for?

The Axofreeze is ideal for biomedical research institutions, university institutes, hospital laboratories, biobanks, pharmaceutical companies, and diagnostic laboratories. Network capability via RS485 interface, the password-protected control system, and long-term data recording over 10 years via USB make it particularly suitable for GMP- and GLP-compliant environments.

How does the dual cooling system differ from conventional ultra-low temperature freezers?

The dual cooling system features two completely independent refrigeration circuits. If one compressor fails, the second compressor alone maintains -80°C continuously, whereas in standard ultra-low temperature freezers, a compressor failure can lead to a critical temperature rise. This redundant safety architecture reliably protects valuable samples and provides maximum operational safety, with a warm-up time of only 4.5 hours from -80°C to -50°C.

What accessories and maintenance are required for operation?

Optional accessories include drawer racks for boxes of any size, cost-effective polypropylene or cardboard boxes, CO2 backup systems, alarm notifications for push messages/email/SMS, as well as biometric access systems (fingerprint scanner, chip card) and temperature recorders. Regular cleaning of the dust filter on the easily removable front grille with magnetic mounting is important. The unit features two cable ports (Ø 25 mm) for external temperature sensors for monitoring.
