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

The Vestfrost VT546-45 is a low-temperature chest freezer capable of reaching and holding temperatures as low as -45°C. It is designed for environments where standard commercial freezing is insufficient — most commonly laboratories, medical and pharmaceutical storage, blood banks, research facilities, and specialist food science applications. This is not a standard catering chest freezer; it is a purpose-built ultra-low temperature unit for critical storage requirements.

Where conventional chest freezers typically operate in the -18°C to -25°C range, this unit goes considerably further. That extended temperature range makes it suitable for storing biological samples, certain pharmaceutical products, or materials that degrade above -30°C. The single-compressor system is designed to run continuously and maintain stable internal temperatures even when ambient conditions vary, which matters considerably in environments where temperature drift carries real consequences.

In practical terms, operators benefit from:

• Digital temperature controller with reliable, readable readout for day-to-day monitoring
• Audible and visual alarms that alert staff to any temperature excursion promptly
• Prepared connections for external temperature logging systems, supporting compliance requirements
• Option to connect a CO2 backup system, providing continuity of cold storage during a compressor event
• Lockable lid, appropriate for controlled-access storage environments

The unit uses a hydrocarbon refrigerant and cyclopentane insulation, both of which carry a lower environmental impact than older synthetic refrigerants and foam blowing agents. Installation is straightforward — the unit is plug-and-play on a standard supply — but it is worth considering ventilation around the cabinet given the intensity of the refrigeration cycle. Sufficient clearance around the unit is important for compressor performance and longevity. This is a heavy piece of equipment and floor loading should be checked in advance for upper-floor or mezzanine installations.

The VT546-45 is best suited to laboratories, hospitals, pharmacies, research institutions, and any environment requiring certified ultra-low temperature storage. It is not intended as a general-purpose catering freezer. If your requirement sits in the standard -18°C to -25°C range, a conventional commercial chest freezer will serve better and run more economically. For storage volumes greater than 495 litres at ultra-low temperatures, larger capacity models in this category are available.
