Vestfrost VT546-45 495 Ltr Ultra-Low Temperature Chest Freezer -45°C

Product No: VT546-45

Product Description

The Vestfrost VT546-45 is a purpose-built ultra-low temperature chest freezer designed to reach and maintain temperatures as low as -45°C. This places it in an entirely different category from standard commercial catering freezers, which typically operate in the -18°C to -25°C range. It is built for environments where temperature stability is critical and where temperature excursions carry serious consequences — laboratories, blood banks, pharmacies, hospitals, and specialist research or food science facilities.

The single-compressor refrigeration system is designed for continuous operation, maintaining stable internal temperatures even as ambient conditions fluctuate. This kind of consistent performance matters in regulated environments where documentation and traceability are as important as the cold storage itself. The unit uses a hydrocarbon refrigerant and cyclopentane foam insulation, both of which carry a lower environmental impact than older synthetic alternatives.

From a practical standpoint, the unit is equipped to support the monitoring and compliance demands of professional storage environments:

  • Digital temperature controller with clear, readable display for routine monitoring
  • Audible and visual temperature alarms to alert staff to any excursion promptly
  • Prepared connections for external temperature logging, supporting audit and compliance requirements
  • Option to connect a CO2 backup system, maintaining cold chain continuity during a compressor event
  • Lockable lid, appropriate for controlled-access or security-sensitive storage settings

Installation is straightforward on a standard supply connection, but adequate clearance around the cabinet is important given the intensity of the refrigeration cycle — restricted airflow will affect compressor performance over time. This is a substantial piece of equipment, and floor loading should be verified before installation on upper floors or mezzanine levels.

The VT546-45 is well suited to laboratories, healthcare settings, pharmacies, and research institutions with a requirement for certified ultra-low temperature storage. It is not a general-purpose catering freezer, and if your requirement sits within the standard commercial range, a conventional chest freezer will serve the purpose more economically. For sites requiring greater storage volume at ultra-low temperatures, higher-capacity models in this category are available.

If you have specific compliance, temperature range, or installation questions before committing, our team is glad to talk through the details with you.
