D40SSH Mobile Fridge/Freezer

The D40SSH is a 40-litre portable fridge/freezer engineered for reliable transport refrigeration throughout Africa. Built with a rugged hard-body cabinet and stainless steel interior and exterior, it is designed to handle harsh road conditions while remaining easy to clean and maintain.

A digital temperature controller allows the unit to be set as either a fridge or a freezer, covering a 10°C to −20°C operating range for flexible cold storage. To support mobile use without complicated power hardware, the D40SSH runs directly from a vehicle’s 12V or 24V DC supply and can also be plugged into 110/220V AC mains power — no external inverter required.

Features such as a lockable lid, low-voltage cut-out, efficient power consumption, and the ability to retain cold when switched off make it well suited to off-road, fieldwork, and trailer applications. Minus40’s medical units are supported by the Minus40 service warranty, and an optional annual service agreement can be specified.

Features

• Lockable lid — helps keep temperature-sensitive contents secure during transport and in the field
• Rugged construction — hard-body cabinet with stainless steel interior and exterior for demanding farm and veterinary environments
• Low-voltage cut-out — protects the vehicle battery during extended field use
• Fridge or freezer mode — selectable performance for flexible cold storage and transport
• Efficient power consumption — designed for mobile environments where power availability is limited
• Retains cold when switched off — supports temperature stability during short stops, transfers, or power interruptions
• Reliable cold-chain support — designed to help maintain set temperatures while moving between sites
• Off-road ready — suitable for rough terrain and off-road trailers

Use Cases

• Veterinary vaccine transport — keeping vaccines and temperature-sensitive medicines within range while moving between farms and sites
• Animal health fieldwork — mobile cold storage for veterinary teams working in remote or off-grid areas
• Farm and agri supply runs — reliable refrigeration for temperature-sensitive materials during long drives and rough-road travel
• Cold-chain support with flexible power — field refrigeration where vehicle DC and/or mains AC is required (no inverter)
