B110/220H Vaccine Fridge

The B110/220H is a 110-litre upright vaccine refrigerator designed for reliable 2°C to 8°C storage in hospitals, clinics, pharmacies, and public health facilities where cold-chain integrity and power resilience are essential. 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 CFC-free high-density polyurethane foam insulation for extended thermal retention. Fan-assisted cooling delivers even temperature distribution across the full cabinet, while three adjustable perforated stainless steel shelves allow flexible stock organisation. 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. Built-in voltage protection safeguards the compressor and control systems against electrical supply fluctuations common in African healthcare environments. Anti-freeze protection helps prevent accidental freezing of vaccines and temperature-sensitive medicines.

The B110/220H maintains safe storage conditions for up to 52 hours at 32°C ambient temperature following a power interruption — a performance level verified to WHO PQS standards. A swing-open service door provides easy access to the condenser for routine maintenance. Backed by Minus40’s service support, with optional maintenance agreements available.

Features

• 2°C to 8°C operating range — stable vaccine storage for healthcare environments
• Fan-assisted cooling for even temperature distribution across the cabinet
• Digital controller with LED display
• Solar-powered display showing cabinet temperature when mains power is unavailable
• Anti-freeze protection preventing accidental freezing of vaccines and temperature-sensitive medicines
• Audible and visual alarms for high/low temperature, door-open, and dirty condenser events
• Built-in voltage protection for reliable operation under variable electrical supply conditions
• 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 reaching temperatures that could damage vaccines and biological products. Built-in voltage protection safeguards the compressor and control systems against supply fluctuations common in African healthcare environments. The lockable latch restricts unauthorised access and supports product security in shared or public-facing facilities.

Temperature Control

The B110/220H 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.
