The B170/220H is a 170-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 170-litre capacity, while three adjustable stainless steel shelves and two drawers allow flexible stock organisation for different pack sizes and configurations. 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 precise 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 prevents accidental freezing of vaccines and temperature-sensitive medicines, reducing the risk of stock loss. Built-in voltage protection safeguards the compressor and control systems against electrical supply fluctuations common in African healthcare environments.
The B170/220H maintains safe vaccine storage conditions for up to 50 hours at 32°C ambient temperature following a power interruption — a performance level verified to WHO PQS standards. Backed by Minus40’s service support, with optional maintenance agreements available.

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 prevents 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 maintains product security in shared or public-facing facilities.
Temperature Control
The B170/220H uses a digital controller with an LED display to maintain a stable temperature within the 2°C to 8°C range, with temperature accuracy of ±2°C. Fan-assisted air circulation ensures uniform temperature distribution throughout the 170-litre cabinet, preventing 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. The B170/220H maintains safe storage conditions for up to 50 hours at 32°C ambient temperature following a power interruption — a performance level verified to WHO PQS standards. Automatic defrost prevents ice accumulation on the evaporator, maintaining consistent cooling performance without manual intervention.
