Cold chain management remains a critical factor in safeguarding the integrity of temperature-sensitive medical products, especially in resource-constrained settings. Power instability, limited space, and mobile service delivery continue to pose real challenges for health facilities across Southern Africa.
In response to these evolving needs, Minus40 has introduced three compact medical refrigeration solutions: the MED35GHD Countertop Fridge, B65/220H Vaccine Fridge, and D70M Mobile Fridge. Each model is engineered for environments where standard-sized units are impractical, yet compliance, performance, and reliability cannot be compromised.
Shared Performance Characteristics
Although these units differ in capacity and application, they share the same core engineering and safety principles:
- Tightly regulated temperature control (2°C to 8°C) via digital controllers
- Fan-assisted cooling for temperature uniformity
- Stainless steel interiors for durability and infection control
- Integrated alarms for temperature deviation or door opening events
- Built-in voltage protection, safeguarding against electrical instability
- Space-efficient upright form factors, ideal for fixed or mobile installations
All three models are designed and manufactured in South Africa and supported by Minus40’s national service infrastructure and optional maintenance agreements.
MED35GHD: Countertop Cooling for Clinical Precision
At just 35 litres, the MED35GHD is the most compact unit in the Minus40 range, offering full medical-grade refrigeration within the footprint of a standard microwave. Its size makes it especially well suited to consulting rooms, aesthetic practices, veterinary clinics, and laboratory benches.
Despite its dimensions, it includes a lockable glass door, fan-assisted cooling, and a pre-fitted temperature probe port for independent monitoring — features often absent from smaller medical fridges.

B65/220H: High Standards in a Small Format
The B65/220H is a 65-litre vaccine and medication fridge designed for fixed installations where space is limited. Commonly used in pharmacies, primary care facilities, and satellite clinics, it combines high storage reliability with a compact, undercounter footprint.
Key features include a 26-hour holdover capacity at 32°C ambient temperature, a lockable self-closing door, LED internal lighting, and both standard and solar digital displays. It offers a dependable solution for daily clinical use under challenging power conditions.

D70M: Field-Ready Cold Chain for Mobile Health Delivery
The D70M offers the same internal volume as the B65/220H but is purpose-built for use in mobile clinics, outreach vehicles, and rural field settings. In addition to mains power, it operates on 12/24V DC and features integrated eutectic cooling technology, capable of maintaining cold temperatures for up to 26 hours without power.
Its rugged construction and dual power capability make it an effective solution for maintaining cold chain integrity during transport or in locations with unreliable infrastructure, particularly in public health, animal health, and humanitarian settings.
