B130/40/220H Vaccine Fridge with Freezer

The B130/40/220H is a combined vaccine fridge and freezer designed for healthcare facilities requiring both 2°C to 8°C vaccine storage and on-site ice pack freezing capability in a single upright unit. With a 130-litre fridge compartment and a separate 40-litre freezer compartment operating at -15°C to -10°C, it is well suited to clinics, hospitals, pharmacies, and public health programmes where cold-chain management and outreach preparation occur in the same facility. 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. Two independent compressors — one dedicated to the fridge, one to the freezer — allow each compartment to operate and be controlled separately, without either affecting the other. Fan-assisted cooling delivers even temperature distribution across the fridge compartment, while three adjustable perforated stainless steel shelves support flexible stock organisation. Double door gaskets on both compartments enhance sealing and temperature retention, and a pre-fitted probe hole supports integration with independent temperature monitoring devices.

Each compartment is managed by its own digital controller with an LED display, providing independent temperature regulation. An additional solar-powered display shows fridge compartment temperature 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 in the fridge compartment. Built-in voltage protection safeguards both compressors and control systems against electrical supply fluctuations common in African healthcare environments.

The fridge compartment maintains safe vaccine storage conditions for up to 52 hours at 32°C ambient temperature following a power interruption. Automatic defrost operates on the fridge compartment; the freezer uses manual defrost to maintain consistent sub-zero temperatures. 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

• 52-hour fridge holdover at 32°C — cold-chain protection during power outages
• Integrated 40-litre freezer compartment at -15°C to -10°C for ice pack preparation supporting vaccine outreach
• Two independent compressors — one dedicated to the fridge, one to the freezer — for separate compartment control
• Dual digital controllers each with LED display for independent temperature regulation of fridge and freezer
• Fan-assisted cooling for even temperature distribution across the 130-litre fridge compartment
• Solar-powered display showing fridge 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 fridge 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 fridge compartment reaching temperatures that could damage vaccines and biological products. Built-in voltage protection safeguards both compressors 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 B130/40/220H uses two independent digital controllers — each with an LED display — to maintain separate temperature ranges in the fridge (2°C to 8°C) and freezer (-15°C to -10°C) compartments, with controller accuracy of ±2°C. Fan-assisted air circulation supports uniform temperature distribution throughout the 130-litre fridge compartment, helping to prevent hot and cold spots that could compromise vaccine efficacy. An additional solar-powered display shows fridge compartment temperature when no mains power is present, enabling cold-chain monitoring during outages without opening the unit. Automatic defrost operates on the fridge compartment; the freezer compartment uses manual defrost to maintain consistent sub-zero temperatures without unintended temperature rise.
