Engineering Excellence Since 1975
Minus40 began its journey in 1975 with a clear purpose: to provide dependable refrigeration solutions for rural communities facing unreliable power supply.
By the late 1990s, we collaborated with South Africa’s Department of Health and the CSIR to create a vaccine refrigerator featuring an industry-first 50-hour holdover capability – a direct answer to the global vaccine cold chain challenges highlighted by the Bill & Melinda Gates Foundation in 2015.
This breakthrough shifted Minus40’s focus towards specialised medical and laboratory refrigeration – a direction that continues to shape our business today. In 2010, new leadership accelerated our innovation pipeline and reinforced our longstanding commitment to quality and reliability. Every Minus40 product is now sold with a service guarantee and backed by a trusted, nationwide support network.
Over the years, our product offering has grown to serve every stage of the human lifecycle – from breast milk storage solutions to advanced mortuary refrigeration systems – ensuring care, precision and performance where it matters most. Today, Minus40 excels in five core refrigeration categories – Medical, Vaccine Cold Chain, Laboratory, Mortuary and Alternative Energy solutions – all underpinned by our unwavering commitment to service excellence.
Global Leadership in Specialist Refrigeration
At Minus40, we lead the way in specialist refrigeration designed for the demanding conditions of the African continent. Our equipment is built to withstand harsh environments while ensuring the safety and quality of sensitive materials, from vaccines to laboratory samples. Recognised for setting new industry standards, our signature vaccine refrigerators maintain precise temperatures for over 50 hours without power – a benchmark in cold storage reliability for remote and off-grid locations.
With decades of experience in medical refrigeration, laboratory refrigeration and cold chain solutions, we are trusted by healthcare providers and laboratories across Southern Africa and beyond. By combining advanced technology, durability and dependable service, Minus40 continues to raise global standards in refrigeration performance and reliability.
