B340/220H Vaccine Fridge

The B340/220H is a 340-litre upright vaccine refrigerator designed for reliable 2°C to 8°C storage in hospitals, clinics, pharmacies, and public health facilities where high-capacity cold-chain storage and strong power resilience are essential. With a 64-hour holdover at 32°C and a 340-litre cabinet, it is well suited to environments managing large or critical vaccine stocks where extended power disruptions cannot be ruled out. Developed to Global Health Cold Chain specifications with support from the South African National Department of Health, it is purpose-built for the demands of healthcare environments across Southern Africa.

The cabinet features a Chromadek steel exterior and stainless steel interior, supported by 80mm CFC-free high-density foam insulation engineered for extended thermal retention. Fan-assisted cooling delivers even temperature distribution across the full cabinet capacity, while five adjustable perforated stainless steel shelves and two drawers support flexible stock organisation for different pack sizes and configurations. Double door gaskets enhance sealing and temperature retention, and a pre-fitted probe hole supports integration with independent temperature monitoring devices for cold-chain verification and compliance.

A digital controller with an LED display maintains temperature within the 2°C to 8°C range, supplemented by an additional solar-powered display that shows cabinet temperature even when mains power is absent. Audible and visual alarms activate for high/low temperature excursions, door-open events, and a blocked condenser. Anti-freeze protection helps prevent accidental freezing of vaccines and temperature-sensitive medicines. Built-in voltage protection safeguards the compressor and control systems against electrical supply fluctuations common in African healthcare environments.

The B340/220H maintains safe vaccine storage conditions for up to 64 hours at 32°C ambient temperature following a power interruption. Backed by Minus40’s service support, with optional maintenance agreements available.

• Pre-fitted probe hole for independent temperature monitoring and cold-chain compliance

Safety

Audible and visual temperature alarms alert staff when cabinet conditions fall outside the 2°C to 8°C operating range. A door-open alarm reduces the risk of inadvertent temperature excursions during busy operational periods, and a dirty condenser alarm supports proactive maintenance scheduling. Anti-freeze protection helps prevent the cabinet from reaching temperatures that could damage vaccines and biological products. Built-in voltage protection safeguards the compressor and control systems against supply fluctuations, surges, and spikes common in African healthcare environments. The lockable latch restricts unauthorised access and supports product security in shared or public-facing facilities.

Temperature Control

The B340/220H uses a digital controller with an LED display to maintain a stable temperature within the 2°C to 8°C range, with controller accuracy of ±2°C. Fan-assisted air circulation supports uniform temperature distribution throughout the cabinet, helping to prevent hot and cold spots that could compromise vaccine efficacy. An additional solar-powered display shows cabinet temperature when no mains power is present, enabling cold-chain monitoring during outages without opening the unit. Automatic defrost helps prevent ice accumulation on the evaporator, maintaining consistent cooling performance without manual intervention.
