Vestfrost VT406-45 383 Ltr Ultra-Low Temperature Chest Freezer -45°C

The Vestfrost VT406-45 is a specialist ultra-low temperature chest freezer designed to maintain internal temperatures down to -45°C. This is not a standard commercial catering freezer — it is built for environments where deep, stable freezing is a genuine operational or regulatory requirement. Typical applications include laboratory storage, pharmaceutical and medical facilities, veterinary practices, and specialist food processing operations where conventional freezing depths are insufficient.

The unit runs on a single-compressor system engineered for continuous operation at extreme low temperatures. Temperature stability is central to its design: the cabinet holds consistent internal conditions even as ambient temperatures shift, which matters considerably when the stored materials are sensitive to any variation. A digital controller makes monitoring straightforward, and the unit is prepared for external temperature logging — relevant wherever audit trails are required by protocol or regulation.

From a practical standpoint, the key operational features include:

• Audible and visual alarms for immediate notification of temperature deviation
• Prepared for CO2 backup system integration where protocols require it
• Fitted lock for access control and security
• Hydrocarbon refrigerant for a lower environmental footprint
• Mains-powered with no specialist commissioning needed on installation

Installation is uncomplicated — no gas or water connections are required. Placement does need some thought, however. The unit should be positioned in a well-ventilated space, as ambient temperature around the cabinet directly affects how consistently the compressor can sustain ultra-low operating levels. Floor load capacity is also worth confirming before positioning a fully loaded chest freezer of this size.

This unit is well suited to regulated or specialist environments with a clear requirement for temperatures well below standard commercial freezing. It is not the right choice for general catering cold storage, where a conventional chest or upright freezer would be more appropriate and considerably more economical to run. If your volume or temperature requirements sit outside what this unit covers, alternatives are available.

If you are working through whether ultra-low temperature storage is the right specification for your setting, or have questions about placement, monitoring, or backup requirements, we are happy to talk it through before you make a decision.
